leviathan

Underworld*

A Blue-Haired Man with a muscular body was standing outside a mansion with well-made designs and fortified barrier magic surrounding the layout.

*Knock* *Knock*

The Man crossed his muscular arms as he waited for the door to be opened. And to his convenience the door was answered. A man with Dark Brown Hair was standing inside the mansion, behind the door. The Mans Emerald Eyes staring deep into the Visitors Atlantic Blue Orbs.

"Ah, welcome Leviathan-sama." Greeted the Brown Haired Man as he welcomed the newly revealed Satan. "Basara, your household is as beautiful as ever." Complimented Leviathan with a genuine smile.

"You're too kind my lord." Said Basara Modestly. The Satan giggled and soon entered the Beautiful Mansion. As Leviathan stepped inside the Mansion and scanned the interior, he was greeted by a beautiful Woman with White-ish Blonde Hair, very nice curves and a massive bust size.

"It is wonderful to meet you again, Leviathan-sama." Greeted the Busty woman as she bowed her head down with respect. "Raise your head, Helena. I wouldn't want your son to think that I'm a Tyrant of some sorts." Said Leviathan as he chuckled shortly.

"Of course, if it is what you wish..." Stated Helena with a smile as she rose her head. "Now, where is that ever growing Handsome Young Man?" Asked Leviathan as he looked around the Mansion, hoping to spot the son of Basara and Helena.

Leviathan looked around the Mansion but could not find the boy, he was about to sigh in disappointment until he was called out.

"Uncle Leviathan!" Shouted a Young Man with Light Brown hair and Brown Eyes. It was obvious to Leviathan that the boy had taken a lot from his Father, which wasn't necessarily a bad thing.

Leviathan grinned as the boy came crashing down on him, embracing the boy with a hug. "It seems that you are stronger than the last time we met Issei." Said Leviathan with a grin as he and Issei connected their fists.

"I've been training hard! I can even do a bit of Water Magic now!" Informed Issei as he opened his palm and a sphere of water formed. "That's good! You are slowly becoming a Leviathan in your own way. And keep training your body the way you are right now and the girls wont be able to resist you when you grow up!" Teased Leviathan as he soon smirked when he saw Issei blush.

"I see you're still trying to get my Brother to become a Leviathan fanatic... But it'll never happen." Said a new female voice, getting Leviathan to look at the voice's direction with a slightly annoyed aura.

"I did not realize you were awake, give the True Leviathan his due respect. It is embarrassing to see a member of the family disrespecting Leviathan-sama." Said Helena slightly disappointed in her Daughter's rude manners.

"Fear not mother, I shall return to my slumber after a good meal. And I don't care about his due respect, whatever he does to my brother I know that Issei will follow the path of Swordsmanship and not Wet girly magic." Informed the Daughter of Helena with clear distaste towards the Satan.

"Good to see you too, Nashetania." Greeted Leviathan Sarcastically. "Spare me the sarcasm." Said Nashetania as she headed towards the Kitchen to make her meal.

Leviathan looked to his side to see Issei frowning, he knew that the boy wanted to learn how to use the same magic he did. But he also knew that Issei loved his sister very much, the two went through a tragedy and that apparently got them closer to each other.

"Issei could you come with me for a bit?" Asked Leviathan. "May I ask what for?" Asked Helena curiously. "I merely wish to discuss something with the boy." Replied Leviathan vaguely. "I see, forgive me for my insolence..." Apologized Helena as she bowed her head down.

"Well?" Asked Leviathan as he looked towards Issei. "Sure!" Replied Issei Enthusiastically. Leviathan nodded with a grin as he created a Magic Circle which teleported both him and Issei.

...

Issei was surprised to see that he had been teleported to Leviathan's office. The boy looked on with awe and praise as the Satan's office looked like the World's Best Aquarium, with the exception of fish.

Leviathan saw this and grinned proudly. "So Issei, how do you like my office?" Asked Leviathan curiously, although he already knew the boys answer.

"It's awesome! Wow, you really take being a Leviathan seriously!" Replied Issei Enthusiastically. "Hehehe, well anyway... I bet you're wondering why I brought you here right?" Asked Leviathan as he crossed his arms.

Issei nodded positively, which gave Leviathan the signal to release a small amount of his aura. This shocked Issei as this powerful aura was almost enough to bring him down on his knees, and Issei knew that the Satan wasn't releasing anything close to 5% of his full power.

'T-This aura is amazing! B-But it doesn't seem hostile... It's like a beacon of some sort...' Thought Issei still in shock at the sudden outburst of power. Soon enough the Leviathan smiled and refrained from letting anymore of his aura leak out.

Issei and Leviathan just stood there, silent. Until the door to the office burst open.

*BURST!*

"I have arrived Grandfather!" Shouted a girl with long brown hair, a pair of glasses and blue-grey eyes. "Good to see you, Katerea. This is Issei Hyoudou, the Son of one of my most trusted allies." Greeted Leviathan as he introduced Issei. The girl looked at Issei with a slight blush but soon greeted him.

"I-It's nice to meet you Hyoudou... -san." Greeted Katerea as she bowed her head down in respect. Issei blushed at the girls cute welcome, but the boy controlled his hormones and greeted the girl properly. "It's nice to meet you too, Katerea-chan!" Greeted Issei. Katerea blushed at the addition of chan, but this simply made Leviathan grin, as it seemed something was going according to his plans.

"Now, Issei. The reason I brought you here was because I wanted to introduce you to my Nephew, Katerea Leviathan." Stated Leviathan as he grinned. "But, why did you want me and this boy to meet Grandfather?" Asked Katerea curiously as she tilted the staff that she was holding. "W-Well... You see..." Uttered Leviathan nervously before looking towards Issei's direction and grinning.

"Issei, Katerea here will become your fiancée." Stated Leviathan, not taking no for an answer. Issei looked towards Leviathan for a few moments, and then to Katerea, and then back to Leviathan. Soon the two younglings shouted simultaneously.

"WHHHAAATTT?!" Shouted Katerea and Issei Simultaneously. "What do you mean she's gonna be my fiancée?!" Asked Issei shocked. "Exactly what it means, the two of you will one day get married and make children." Replied Leviathan with a grin. "Grandfather! You can't just make that happen because you desire it! Not even you have the power to do that legally!" Argued Katerea with a fact.

Leviathan frowned and looked down at the ground, his bangs covering his eyes. Katerea paled a bit after seeing here Grandfather like this, she had made him mad. Or so she thought.

"T-That's true..." Uttered Leviathan, getting the hopes of Issei and Katerea up. "BUT! Both of your parents have already agreed to it! Hahahaha!" Added Leviathan before laughing, with a victorious smirk pasted across his facial structure.

"N-No way! There's no way my mother would agree to a marriage with someone I don't even know!" Stated Issei with shock and disbelief. "True, but it was your Father who agreed to this! Basara Toujou Hyoudou!" Informed Leviathan before laughing once again.

"F-Father..." Muttered Issei as he fell on the ground on his knees, defeated. '... Why am I not surprised?' Thought Issei before an image of his father laughing with his arms crossed appeared on his head.

"S-So I really am going to marry this boy?" Asked Katerea, sounding defeated as well. But even though she wouldn't admit it, she found the boy to be handsome. 'O-Only slightly!' Said Katerea in her head.

"But fear not! The Marriage will commence once both of you are at the age of 18! And once you are a Devil King Katerea, Issei will be your greatest warrior and your lover at the same time!" Reassured Leviathan, as he stated some reassuring news.

"THAT'S NOT REASSURING AT ALL!" Shouted Issei and Katerea at the same time.

...

*8 Years Later*

Leviathan was sitting inside his office, with full battle armor. 'A shame that we must attack Heaven now of all times... I guess I'll be there for dinner at the very least.' Thought Leviathan before a soldier opened the door to his office.

"Leviathan-sama! Lucifer-sama is calling for you." Informed a Devil Soldier. "Thank you, tell Lucifer that I'll be there soon." Said Leviathan. The Soldier nodded before leaving.

Leviathan summoned a magic circle which fit perfectly beside his ear. It seemed to be ringing like a cellphone.

"Hello?" Asked a man who seemed to be contacted by the Satan. "Basara... It's Leviathan." Said Leviathan, he chuckled a bit when he heard Basara's coffee spill from the magic circle or phone in this case.

"L-Leviathan-sama! What do you require from me?" Asked Basara regaining his composure. "Look... I'm about to gather with the other Satan's to prepare for our attack on Heaven, and since our opponent is God... I wanted to thank you for your loyalty, your family has served me well." Stated Leviathan with a sad tone, even a Devil can develop feelings of comradery.

"Leviathan-sama... You speak as if your death is guaranteed." Muttered Basara lowly. "Hehehe... You know it is. But when Issei learns of my death, tell him it wasn't in vain... Because I will NOT die without taking that old geezer with me." Said Leviathan confidently.

"... He will be sad... But what about his engagement?" Asked Basara concerned. "Oh yeah... When I die, the engagement will definitely be canceled as I have sponsored it." Replied Leviathan disappointed. "And I wanted to see it through as well..." Added Leviathan.

"Heh, the two of them became really good friends too... Just for the engagement." Stated Basara. "Yeah... But maybe this time the man will have to work for his girl, whoever it may be..." Said Leviathan jokingly.

Basara stayed quiet as he couldn't find it within himself to laugh, or even chuckle. "... Basara, you are relieved of your duties." Stated Leviathan as he retracted the magic circle, disconnecting the call with Basara Hyoudou.

Leviathan then exited his office and headed to the battlefield alongside Lucifer, Asmodeus and Beelzebub. The Satan's and their armies flew up and entered the massive portal to Heaven, the Great War that had been going on for years was about to end.

'Time to die... I suppose.' Thought Leviathan as he charged in with his massive army.

"... Basara, you are relieved of your duties." Stated Leviathan as he disconnected his link with Basara Toujou Hyoudou. "L-Leviathan-sama?! Leviathan-sama!" Shouted Basara as he was shocked at the sudden goodbye.

Basara stood up and headed towards the balcony of his mansion, which was at the second floor. He watched from far away, the armies of Devils charging into Heaven. What caught his eyes though, was a certain man with godly armor and streaks of water surrounding his form.

'Leviathan-sama... Even if you die, my family will serve your descendants and those who hold the title of Leviathan... That is one thing that not even you can take away, Leviathan-sama.' Thought Basara as he closed his eyes. But his thoughts were interrupted when a spear of light penetrated his knee.

'W-What...?' Thought Basara before his head was hit by another Light Spear. From the sky, descended ten angels. 'A-An ambush? The Capital is in danger... I-I'm sorry Issei... Helena... And Nashetania.' Thought Basara before his body disintegrated due to the Angels.

Helena headed to the balcony as she heard some commotion, only to witness the terrifying sight of her husband getting killed by a group of Angels. "B-Basara? N-No... It cant be!" Uttered Helena in disbelief as her husband disintegrated.

"I-It's the Tsunami Queen! Kill her quickly!" Ordered one of the Angels as the group started throwing light spears at the woman. The Light Spears were all blocked by a wall of water. "N-No way!" Uttered one of the Angels.

"Destroy." Muttered Helena as the water morphed into multiple spears and shot themselves at the Angels, killing six of them. Only four of the Angels survived the attack, this was most likely due to their high rank, the angels had eight wings.

"Take this!" Shouted one of the female Angels as she created a massive light spear and threw it at the Tsunami Queen. "Useless." Muttered Helena as she formed a beast of some sort with her water magic and used it to devour the Light Spear. The Angel looked on in horror as the Water Beast soon ascended and devoured her entire body.

Helena quickly dashed towards one of the angels and stabbed them with a sword made out of water from behind. "W-Why you..." Uttered the Angel before he fell on the ground lifeless.

Helena faced the other two Angels to see them chanting some sort of spell, but she wouldn't allow it to happen. Helena unleashed a barrage of water attacks, but there was a powerful barrier surrounding the two Angels. 'Are they calling for backup?' Thought Helena as she continued thrusting her water spears at the barrier.

"Your prayers have been answered my brothers..." Stated a man with short brown hair and a beard, eight wings shining brightly behind his back and a halo above his head. "Y-You?! Why are you not in Heaven assisting the other Angels?!" Asked Helena confused at the sudden appearance of the Legendary Angel.

"I was part of the Ambush Team, assigned by my father... But it seems I was too late to save some of them, forgive me o' lord." Replied the Angel as he prayed for forgiveness. Helena looked doubtful, she was not sure she could take this man alone. However she then saw Nashetania outside the mansion with Issei.

"Mother! I'm coming!" Shouted Nashetania as she quickly summoned multiple of her blades. "Me too!" Said Issei as he looked like he was about to summon something, until his mother interrupted him. "No! Both of you stop! I will not have you dying here! Nashetania, take Issei and run!" Ordered Helena.

Knowing her mother, Nashetania knew that her mother would just scold her if she didn't obey. "F-Fine..." Replied Nashetania hesitantly. "What?! Just like that!? We cant leave her here!" Shouted Issei before he was quickly knocked out by Nashetania as she summoned a blade behind the devil and used its hilt to knock him unconscious.

"That's a good girl..." Said Helena with a loving smile. Nashetania formed tears on her eyes as she quickly ran away from their soon to be destroyed mansion.

"Shall we continue?" Asked the Angel, who had been patiently waiting for the family and its matters to finish. "Yes, I am fully prepared to die fighting you... Son of God, Jesus Christ." Replied Helena as her body was surrounded by water.

*20 Years Later*

"Wake up! If you don't wake up I'll k-k-kiss you!" Uttered an Alarm with a Tsundere girl. A boy with Light brown hair and brown eyes was waking up, he soon turned his alarm off as it was annoying him to a slight degree.

"Yo, Issei wake up!" Said a girl with amazing curves, white-ish blonde hair, crimson red eyes and a very nice bust size. "Onee-chan... Five more minutes!" Said Issei as he rolled beneath his blanket. "You know it's your first day at school! If mother were here she would splash you with water, so you're lucky I'm not all too familiar with that archetype of magic!" Retorted Nashetania as she started to pull Issei out of his bed.

"But I'm like 38 years old! Why do I have to go to school?!" Asked Issei desperately as he tried to get back to bed. "You're only 18 in human age! So you have to go to school!" Replied Nashetania as she successfully threw Issei onto the cabinet which contained his uniform.

"Ugh! Fine!" Said Issei as he gave up and simply proceeded to put his uniform on. "Good, breakfast's downstairs." Stated Nashetania as she left the room. 'Jeez, she's wearing nothing but a t-shirt and really short shorts... I wonder if she's just teasing me or trying to get me to make a move on her...' Thought Issei as he removed his shirt, beneath was a muscular body with six-pack abs. Issei had a body that girls could die for, but then again so did his sister.

'Maybe it runs in the family...' Thought Issei suggestively as he buttoned his uniform and put his shoes on.

{Partner, you do realize that there are a few Devils attending this "Kuoh Academy" right?} Asked a deep menacing voice, but it seemed that only Issei was able to hear him.

"Of course I do Ddraig, maybe you're thinking too little of me again? Need I remind you that I can fight on par with you in your Prime State." Replied Issei. Getting Ddraig to laugh.

{Hahaha! Your ferocity never ceases to entertain me, Partner.} Informed Ddraig as he soon returned to his slumber. 'Back to sleep so soon? Lazy lizard...' Thought Issei annoyed.

As Issei finished getting dressed and packing up, he proceeded to go downstairs to eat breakfast. Issei looked at the table to see that his Sister had made him some Tempura, which he was grateful for.

"Thanks for cooking my favorite." Thanked Issei genuinely as he began to eat the delicious prawn. Nashetania, who was watching TV smiled at her brother's gratitude.

"Well, if you really wanna thank me... How about a kiss?" Asked Nashetania teasingly. Issei almost choked on his food, but was able to swallow. "Haha... Good one." Said Issei as he interpreted it as a joke.

Nashetania dropped the remote and dashed towards Issei with a small thin dagger. Issei was completely immobilized. "It wasn't a joke..." Whispered Nashetania as she licked Issei's ear.

"W-What... The hell?" Muttered Issei as Nashetania began laughing and went back to the couch where she was watching TV. 'Ddraig... H-Hey you there?' Called Issei in his thoughts.

'Great... He's still asleep...' Thought Issei as he finished eating his meal and exited the house after saying goodbye to Nashetania. He then proceeded to go towards his school.

As Issei was approaching his new school, Kuoh Academy. He could feel the presence of a supernatural being, a fallen angel. 'Hmm? I'm being watched... Azazel perhaps?' Thought Issei as he simply ignored the fallen angel.

...

After a few minutes of walking, Issei had arrived at the gates of his school. There were hundreds of students in the campus and Issei immediately knew that he would be experiencing hell, ironically.

"Wait, is he a student?!" Asked a female student. "... He totally is! He's even wearing the uniform!" Replied a different female student. "He's so hot!" Said a female student blushing.

'Heh, perhaps I can form a Harem here...' Thought Issei. {That would be a massive downgrade, a dragon like yourself should only get the best girls.} Said Ddraig as he complimented Issei.

'That'd be too much, I don't think of myself as a God of some sorts...' Said Issei in his thoughts as he began walking inside the campus. All of the females were looking at him with lust, while the boys looked at him with jealous eyes.

Issei arrived outside of his classroom to be greeted by his teacher. The teacher had told him to wait until he was called so that he may introduce himself properly.

"Alright, we have a new student today. You can come in now." Called the Teacher after settling the class. The slide door was opened and what came in was an incredibly handsome light brown haired male student.

After seeing Issei come in, the girls all squealed in excitement. "Now, introduce yourself." Said the teacher as he gave the boy some chalk. Issei nodded and wrote his name on the board behind him.

"My name is Issei Hyoudou, I was born in Europe and have come to Japan interested in its culture. Please take care of me." Introduced Issei as he bowed his head down. All of his classmates were impressed by his calm demeanor and manners.

"Good job, now I will allow three questions for Issei Hyoudou. Make it count." Stated the teacher as he opened up a panel for questions. Multiple females raised their hands and so did some boys.

Issei looked over to a boy with glasses and picked him as he was raising his hand. The boy smirked as he stood up. "Why did you come here of all places? Did you come to take all of the girls?" Asked the boy with a smirk. As he asked this question, the girls in the class looked at him with fire in their eyes.

"How dare you try to infect him with your perversion!" Shouted one of the girls with pink hair as she tried to hit him with a wooden sword. But was surprised to see that it was blocked before it hit the boy, it was blocked by none other than Issei.

"It's alright, I will answer any question given to me." Stated Issei as he went back in front. Everyone was surprised to see that their new classmate was skilled with Martial Arts.

"Now, I came here because as I said I am interested in the country's culture. And no, I did not come here to take every girl away. I already have a fiancée." Answered Issei as he frowned slightly.

'Well, I guess that last part isn't true... Not anymore at least.' Thought Issei, slightly depressed that he was no longer engaged with the beautiful woman.

"Awww! He's engaged!?" "NOOOO!" Shouted the girls in the class with disappointment, as they no longer had a chance with Issei Hyoudou.

Issei continued to call another student for their question. He called a female with brown hair and glasses. "So, who exactly are you engaged with? And what are her features?" Asked the female, getting Issei to flinch slightly.

'D-Damn... I don't even know anymore, its been ages!' Thought Issei struggling to answer the question. {Heh, you're trapped.} Stated Ddraig before laughing, much to the annoyance of Issei.

"W-Well... She has massive breasts, beautiful blue-grey eyes... And, sexy curves..." Answered Issei, not entirely sure if his answer was correct as Katerea could have changed in the past years.

The boys in the class were drooling as they imagined Issei's fiancée, while the girls were jealous. "A-Alright, thanks for the honest answer." Thanked the girl as she sat down. "Alright! That's enough, we're going to start the lesson now, please find a seat Mr. Hyoudou." Said the teacher as he began writing on the board. Issei nodded as he then found a seat at the back, beside the window.

Issei did not listen to the lesson as he already knew most of the lessons that humans teach to other humans, he simply stared outside the window, waiting for somethin exciting to happen.

"Mr. Hyoudou, could you please answer this equation?" Called the teacher as he noticed Issei was not listening. Issei stood up and answered the problem easily, once finished he went back to his seat. The teacher and the entire class was surprised to see that Issei, who was supposedly not listening, answered the hardest problem with ease.

"G-Good job, Mr. Hyoudou." Complimented the teacher as he continued with the lesson. Soon enough, classes ended and it was time to take a break. Issei headed outside the building and sat under a tree, devouring the tempura his sister made for him.

'Ahh, if there's one thing that Sis does right its Tempura!' Thought Issei joyfully as he swallowed his food. Issei was about to eat another one until he saw someone looking at him.

Issei looked at the direction it was coming from, it seemed to be coming from one of old school buildings, one where the supposed Occult Research Club was located. When Issei looked over to the building, he saw a red haired beauty looking at him, her hair flowing with the air.

'If I'm not mistaken, that's Rias Gremory of the Gremory Household.' Thought Issei as he stared right into her eyes. {You got that right, Partner. There is no mistake, I can sense the aura of a Devil within her.} Said Ddraig informatively.

Issei watched as the Devil closed the window, further denying Issei sight of her. 'Well, at least I have my privacy now...' Thought Issei as he was about to start eating again, until he saw from far ahead that multiple girls were running towards him. "Crap!" Said Issei as he quickly packed his food and began running away.

*Rias POV*

'That boy, he's definitely not human...' Thought Rias as she stared at the handsome young man from inside her clubroom. "Find anything interesting, Rias?" Asked a raven haired beauty with purple eyes and a bigger bust size compared to Rias.

"Yes, this new student. Do you happen to know his name, Akeno?" Asked Rias as she closed the window and sat down on a couch. "Hmm? Him? I believe it was Issei Hyoudou, class 2-B" Replied Akeno as she placed two cups of tea on the table. "Thank you." Thanked Rias as she grabbed a cup of tea and drank it.

"Kindly have Koneko investigate." Ordered Rias as she sipped on her tea. "Understood, Rias." Replied Akeno as she went to do her master's bidding.

'Hopefully you're strong, Issei Hyoudou...' Thought Rias hopefully. But it never occurred to her that this certain devil might've been too strong for her.

Issei had hidden from the dozens of girls that ran after him, but he was safe within a locker. 'What the hell is up with these girls?!' Thought Issei panting softly. {Knowing you already have Godly looks naturally, adding the Boosted Gear's natural ability to attract the opposite sex. It is only natural that humans have no resistance whatsoever to your charms.} Explained Ddraig, getting Issei to smirk a bit.

'Well... If you put it like that...' Thought Issei as an image of a massive harem appeared in his perverted head. {What you're imagining right now isn't impossible, in fact the chance of you obtaining a massive harem is quite high.} Stated Ddraig, getting Issei to blush even more perversely.

As Issei was imagining his harem, an image of a certain brown haired female giggling appeared. "Ah!" Shouted Issei as he then looked down at his pants to see his shaft, pulsing.

{Did you seriously get turned on by the giggle of Katerea Leviathan, but not when imagining a massive harem?} Asked Ddraig, dumbfounded.

'Don't judge me!' Said Issei in his head before paling at the sight of a few females roaming the area. "Damn, where did he go? I really wanted to eat with him..." Said a female student. "I know right? Then we could've fed him!" Said another female, disappointed.

'What other twisted fantasies do they have about me?' Thought Issei as he sighed, waiting for the right time to get out.

As Issei's break time had finished, he went through the rest of the classes. After class, many clubs wanted to recruit him, but Issei couldn't decide yet. Due to this he decided to proceed back to his home, as he had nothing else to do at school.

It was getting late and Issei wanted to get home quickly for breakfast. But he stopped walking at a small bridge to check his messages on his phone, until he noticed the very same fallen angel presence he felt earlier. But this time it was approaching him.

Issei looked to his right to see a pretty raven haired student with purple eyes. She was definitely from another school, as Issei got a close up look on the female attire of Kuoh Academy, much to his disdain.

"U-Umm, you're I-Issei Hyoudou... Right?" Asked the girl blushing, but Issei could tell it was forced. {I can sense evil intention from her, she's probably trying to get close to you... Just to kill you later on.} Stated Ddraig informatively. 'Yeah, I can tell.' Said Issei in his head, but he decided he would play along.

"Y-Yes?" Replied Issei, with incredible acting. {Hahaha! I almost forgot you were an incredible actor.} Said Ddraig as he laughed at his partner's talent.

"That's great! W-Would you like to go out with me?" Offered the Fallen Angel. 'Ah, so a date is her course of action...' Thought Issei amused. {You should accept it, she has a pretty nice rack. And I'm sure Albion would give his opinion on her ass if he was here.} Suggested Ddraig, adding some extra details.

'So you're the Breast Dragon Emperor, while Albion is the Butt Dragon Emperor? Hahahaha!' Thought Issei as he laughed inside his head, struggling to keep himself from laughing in the real world. {D-Don't say anything like that again... For some reason that name makes me depressed...} Said Ddraig as he decided to shut up.

"R-Really?! Sure!" Replied Issei as he accepted the offer. The Fallen Angel perked up, but once again it was forced. "Thank you so much! Does Sunday sound alright?" Asked the Fallen Angel. Issei nodded his head saying yes.

"Great! I guess I'll see you on Sunday! We'll meet by the mall. Sorry, but I have to go now!" Said the Fallen Angel as she began going to opposite direction of Issei. "You still haven't told me your name!" Said Issei, slightly insulted. 'Does she think that I'm so desperate that I'd go on a date with some whose name I don't even know?' Thought Issei.

"It's Yuuma!" Replied the Fallen Angel as she ran off with a fake smile. 'Heh! Hopefully Nashetania and Katerea wont mind.' Thought Issei. {You're not engaged with the descendant anymore, she wouldn't mind even if she were here.} Said Ddraig bluntly. Issei pouted but continued walking back to his home.

*Underworld*

a beautiful girl with long, black hair tied into twin tails was humming a tune as she was walking towards the office of a certain devil. "Sirzechs-chan? You in there?" Asked the girl with a smile on her face. The doors opened and revealed the Crimson Satan, Sirzechs. having the appearance of a man in his early 20's with shoulder length crimson red hair and blue-green eyes, he looked almost exactly like his sister, Rias Gremory.

"Serafall, I see you've received my message." Said Sirzechs as he welcomed the fellow maou inside. "Yep! You said it was important so since I had nothing to do I came immediately!" Informed Serafall as she stepped inside the office and took a seat.

Sirzechs closed the doors and took a seat as well. "So! What's so important that we had to talk in private?" Asked Serafall with a cheerful tone. "Serafall, do you remember one of the old Devil Household's, The Hyoudou Household?" Asked Sirzechs with a serious face.

After hearing this Serafall formed a serious face as well. "Yes I do... Why do you ask?" Replied Serafall, asking another question. "Some of the spies I sent over to watch over my baby sister... Reported some interesting news..." Informed Sirzechs as he took out some files.

Serafall took the files and opened one, reading the content. "Rias has taken interest in making one of Kuoh Academy's new students... Issei... Hyoudou?!" Uttered Serafall as she read the file. "P-Perhaps it could just be a coincidence? I mean, there might be some human families with the name Hyoudou right?" Suggested Serafall, in slight disbelief.

"That's what I thought at first... But, what if he is a member of the Hyoudou Household? Would you take him in as your personal bodyguard?" Asked Sirzechs curiously. Serafall thought really carefully and decided on her answer.

"I mean... The Hyoudou household should be loyal to the Leviathan's right? So if he decides to pledge his loyalty to me then I'll gladly accept his services." Replied Serafall with a cheerful face. Sirzechs smiled at this.

"That would be very beneficial for us, the Hyoudou Household was one of the most powerful back in the day... But they were mostly known for ending the life of Jesus Christ himself." Said Sirzechs informatively. Serafall nodded at this.

"We shall wait and see then. If he does turn out to be a member of the Hyoudou Household... We'll get him to join us." Said Sirzechs.

*Time Skip, Sunday*

Issei was going through his clothes, choosing the best one for his date with the Fallen Angel. The one who called herself, Yuuma.

"You know, I could pick your clothes for you. I do know your body well and I'm a girl." Suggested Nashetania with a slight bit of tease. Issei looked at her with an uninterested face.

"No no, you're my sister. I'm not interested in you at all..." Said Issei Bluntly. Nashetania appeared to have a tick mark on her head as she then pointed a sword at Issei's neck, making him flinch.

"Not interested at all? Do you realize how much that sentence pisses my body off?" Asked Nashetania with an annoyed face. Issei chuckled weakly as he raised his arms up in surrender.

{Waaah! You were the best host I've ever had! And now you're gonna die! I'm sorry I failed you partner!} Sobbed Ddraig jokingly. 'Oh, shut up!' Said Issei in his head.

...

Issei had arrived at the location of his supposed date. He was waiting for Yuuma by a fountain, until he was approached by some cosplayer. 'Hmm? A familiar?' Thought Issei as he accepted the piece of paper given to him, but he knew it was a contract.

{It seems the Gremory girl is making her move on you.} Said Ddraig. 'Yeah... But does she expect to make me her servant? I mean a High-Class devil wont be able to turn an Ultimate-Class like me into her servant.' Thought Issei confused. {Well, some people are desperate. She just happens to be one of them, and besides you're hiding your true strength so nobody knows how powerful you really are.} Stated Ddraig.

'I guess that's true...' Thought Issei before the sight of Yuuma brought him back to reality. "Issei! You really came! Did I keep you waiting?" Greeted Yuuma sweetly.

"Ah, no I actually just got here." Replied Issei before grinning. 'I've always wanted to say that.' Thought Issei happily.

"Well! Let's start shall we?" Suggested Issei as he offered Yuuma his hand. Yuuma blushed before happily grabbing Issei's hand. The two went through a mall, an aquarium and a few restaurants and stores, and they then arrived at a park with a fountain at dusk. Issei assumed that this was the time, the time where Yuuma would try to do something supernatural.

Issei walked with Yuuma, their hands connected. They arrived In front of a fountain at an empty park, where Yuuma suddenly broke off their hands and headed closer to the fountain with her purse in hand.

'She's making her move.' Thought Issei excited. {Best not to be too confident, what if she turns out to be a Fallen Angel Leader?} Asked Ddraig, giving a possible situation.

'A Fallen Angel Leader wouldn't be so inexperienced at hiding their aura.' Said Issei in his head as he then watched Yuuma turn to him with a smile.

"I really had fun today..." Said Yuuma with a cheerful tone. "Yeah, this was the best date ever!" Said Issei, obviously acting. "Can I ask you a question? In order to honor our first date, there's something I'd like you to do... To commemorate this special moment." Asked Yuuma as she approached Issei.

"Sure, I'll do anything." Replied Issei with a fake blush, but it looked convincing. {Partner...} Said Ddraig with a warning tone. 'Wait for it...' Said Issei in his thoughts.

"Would you die for me?" Asked Yuuma with a deeper more mature voice. "I-I'm sorry, could you repeat that? I think there's something wrong with my ears today..." Uttered Issei, still acting. Yuuma grinned as she then whispered to his ear "I want you to die for me..."

"Ahahaha!" Laughed Yuuma as she then began to take the form of a Fallen Angel. 'Ah, so this is how she ends her little act. Amusing.' Thought Issei as she acted like he was shocked and fell to the ground.

"Well, I have to admit I did have some fun today... Considering how naïve and childish you are, things could've been much much worse! And thanks for the gift by the way, very sweet. But! Even so..." Said Yuuma as she summoned a spear that was glowing. 'Naïve and childish? I wonder how she would react to seeing my True state...' Thought Issei darkly. {Don't get carried away, Partner.} Said Ddraig, getting Issei to come back to his senses.

"It's time to die!" Said Yuuma as she threw the Light Spear towards Issei. But she was suddenly shocked, she saw that her Light Spear hadn't pierced Issei's stomach.

Issei was holding the light spear with two of his fingers. "What?! H-How are you holding that?! You're just a mere human!" Said Yuuma surprised. "I was expecting a four winged Fallen Angel at the very least, but hell... This is even more disappointing than I expected." Said Issei disappointed.

"W-Why you!" Uttered Yuuma before throwing two more light spears, but Issei blocked them with his left arm as he activated something that filled Yuuma with pure fear.

{BOOST!} Shouted the Boosted Gear as a gauntlet formed on Issei's left hand. "B-Boosted Gear?! Nobody told me that you held the Boosted Gear!" Stuttered Yuuma as she flew away with panic. "Sorry, but I cant let you go now that you've seen my Boosted Gear." Stated Issei as he released his devil wings, to add even more fear to her spirit, she was facing not only the Wielder of the Boosted Gear, but also an Ultimate-Class Devil.

"Y-You wield the Boosted Gear and you have ten wings?!" Uttered Yuuma with shock. Issei smirked as he flew up and smashed Yuuma down to the ground.

A crater had been formed at the fountain, the Fallen Angel was unconscious due to the hit. Issei landed and retracted his Devil wings.

"Well, time to die I guess." Said Issei bored as he created a magic circle beneath Yuuma and released a blast of energy. Her body had been completely disintegrated.

As soon as all of the damage had been fixed, Issei proceeded to return to his home. His Sadistic side was disappointed, but his Normal side was just purely bored and tired. {You know, you didn't have to use the Boosted Gear...} Said Ddraig confused.

"True, but I wanted to show her fear... So I released my Devil wings and used you, and besides I haven't used the Boosted Gear in awhile." Stated Issei as he shrugged.

...

A magic circle appeared at the very same park where the battle between Issei and Yuuma had commenced, although it wasn't really much of a battle.

As the magic circle's light died down, it revealed Rias Gremory and Akeno Himejima. "No... I was too late..." Muttered Rias as she saw that neither Issei nor the Fallen Angel was in the park.

"I guess we should've arrived earlier. I'm sorry Rias." Comforted Akeno. Rias shook her head and prepared another magic circle to return to their previous location.

*The Next Day*

"P-Please wake up... I don't want to be alone..." Said a sad cute girl, until Issei turned off his alarm. 'Hmm? Nee-san isn't coming to wake me up?' Thought Issei as he rubbed his sleepy eyes. {Well, you know what that means...} Said Ddraig as he cut off his connection with Issei.

'Huh... Oh no...' Thought Issei before a blue magic circle appeared on the floor, as the light died down it revealed a beautiful and attractive young woman with a voluptuous figure, long black hair with split bangs, and hazel gold eyes with cat-like pupils.

"K-Kuroka... What're you doing here?" Asked Issei surprised to see the Wanted Devil. "Nyaa, is it so bad that I want to see My little Issei? Your sis allowed me to come and visit since it's my day off!" Replied Kuroka as she got closer to Issei and wrapped her body around his, which made him blush.

"H-Hey... Wait, day off? What is your job anyway?" Asked Issei curiously. "Nyaa? You didn't know? Nyahaha, well I guess I'll just keep it a surprise." Replied Kuroka, not revealing her Job.

"Well, I need to get dressed so- Ah!" Said Issei before being pushed down on the bed by Kuroka. "Leaving so soon? How about you just be absent for today and we can have some fun here?" Suggested Kuroka as she pulled down her kimono slightly, revealing more cleavage.

"I-I don't think Nee-san would like that very much..." Stated Issei nervously. "Don't worry, I already put down a magical barrier with my senjutsu, only Satan-Class beings will be able to get through that." Reassured Kuroka as she then took off her kimono, revealing her beautiful skin and big bouncy breasts to Issei.

'Shit! Going into overdrive!' Thought Issei as his shaft was about to burst out of his pants' zipper. "At least some part of you wants me." Said Kuroka teasingly as she looked at Issei's bulging pants.

"Ah, to hell with this..." Said Issei as he took his shirt off, revealing his incredible body and six-pack. Making Kuroka blush hard.

*LEMON WARNING! WARNING! WARNING!*

Issei quickly dashed towards Kuroka and slammed her against the wall. "Ahh, I like it rough. Nyaa!" Purred Kuroka as Issei then began kissing her neck, which made her even more horny.

Kuroka grabbed Issei's back with both hands as she then started making out with him, French style. Their tongues battling for dominance. But Issei soon overpowered her and Kuroka released a moan within the kiss.

Issei separated the kiss and carried Kuroka to his bed. Kuroka grinned as she landed on his bed, she then removed her last piece of clothing, which was her pair white panties. As she removed them, she spread her legs giving Issei a good view of her goodies.

Issei stared lustfully as he then removed his boxers and revealed to her his throbbing shaft, clearly it was excited. "Nyaa, so naughty!" Said Kuroka as she got closer and grabbed hold of his cock. Stroking it up and down.

Issei groaned at the sudden pleasure and watched as Kuroka began sucking on it like an ice cream. She was making sexual noises as she sucked which turned Issei on further. Once she stopped sucking, Issei grabbed both of her arms and lay both of them on the bed.

"Spread them..." Whispered Issei, making Kuroka blush but she nodded and spread her legs wide open. Issei only took a few moments before inserting his shaft inside of her cave. "Ahhhh~!" Moaned Kuroka loudly, as Issei began thrusting into her slowly.

"Nyaa~! Ohhh~! Yes~! Faster!" Moaned Kuroka as Issei then started to increase in his thrusting speed. He could feel her wet pussy grinding against his cock inside. Issei groaned as Kuroka moaned.

"Ohh, fuck!" Groaned Issei as he could feel himself climaxing. "Yes! Yes! Give me your babies!" Moaned Kuroka as Issei then thrust as deep as he could and came inside of Kuroka.

"AHHHHH~!" Moaned Kuroka loudly as she could feel Issei's hot stuff inside of her.

*LEMON END!*

As Issei and Kuroka had finished with their session the two got dressed and proceeded downstairs. Kuroka was walking down with a smile of satisfaction on her face, while Issei sighed.

"Hoi! Issei, why didn't you go to school?!" Asked Nashetania slightly irritated. "I-I was distracted! I'm going now!" Replied Issei as he quickly grabbed his packed food and got out of the house. Kuroka looked at the door which Issei had exited and smiled.

"You look pretty happy, Kuroka-Chan. Did something happen?" Asked Nashetania curiously. "Nyaa? Nothing happened, you're just hallucinating." Replied Kuroka as she then sat down the table and began to eat.

Nashetania looked at the Nekomata Devil confused.

Issei was walking pretty fast as he was going to be late for school if he didn't hurry. As he was walking down in the center of the town, he heard a high pitched yelp. He looked to his right to see a short blonde and petite girl had tripped over clumsily. It seems like she had a nun outfit.

'A nun? Quite a dangerous place for someone from the church.' Thought Issei as he simply continued walking, minding his own business. He looked behind once again to see that a tall female with navy blue hair and yellow eyes helped her up and began walking away with her, Issei could sense that the female was a Fallen Angel.

{Are you feeling the need to help that girl? Because I am, she must have an affinity with Dragons.} Said Ddraig. 'An affinity with Dragons? How come I don't feel anything for that girl?' Asked Issei in his head. {Maybe it's because you're sadistic, or maybe you have some high resistance to her affinity.} Replied Ddraig, somewhat jokingly.

'That's not very nice...' Thought Issei as he was getting close to his school. {It was a joke, Partner.} Stated Ddraig as he chuckled at his host's seriousness. Issei sighed after hearing this and just continued walking.

As Issei arrived at his school, he noticed that there were no students outside. Which meant that he was late, Hurriedly Issei ran towards the building and headed for class immediately.

Issei ran the hallways with unfathomable speed and quickly arrived at his classroom's door. Getting ready to apologize he entered the room and immediately bowed his head down. "I'm very sorry! I was late due to some personal matters!" Apologized Issei, getting all of his classmates and his teacher to look at him with shock.

But they weren't shocked because of his apology, they were shocked at something else. "I-Is something wrong?" Asked Issei as he looked up to see everyone looking at him with wide eyes.

"N-No... It's just... You weren't dead?" Asked the Teacher as if he had seen a ghost. "What? Why would I be dead?" Asked Issei confused as he began scratching his head. "The Student Council announced that you had been a victim of a terrible car crash, I will report this immediately. Excuse me!" Replied the Teacher as he exited the classroom and headed to the Student Council Office.

Issei sighed as he then took a seat, waiting for his teacher to return. His classmates were all asking questions, the girls mostly asked if he was ok, while the boys were telling him that he should've died. Issei just waved the questions off, saying that he was never in a car crash accident and that he was home the entire time.

The class heard the door to the classroom open, so everybody immediately returned to their seats. But to everyone's surprise it wasn't their teacher that came in their classroom, it was Rias Gremory.

"Rias-Senpai! What brings you to our classroom?" Asked one of the girls. Rias simply raised her hand at her, telling her to keep quiet. The girl obeyed, Rias soon pointed her hand towards Issei.

"You, I need you to come with me." Said Rias as she pointed her finger at Issei. 'Ah, I understand now...' Thought Issei as he stood up. "Me? What for?" Asked Issei curiously. "We have some important matters to discuss with you, you will be excused from your classes for today." Replied Rias as she approached him and grabbed his hand, pulling him out of the classroom.

"H-Hey! Where are you taking me?!" Asked Issei as he was being dragged through the school hallways. "I will explain everything once we get to the clubroom." Replied Rias as they entered the old school building.

As Rias had gotten Issei inside her clubroom, she offered him a seat, which he accepted. "Oh my, Why did you bring him here, Rias?" Asked Akeno curiously. "He should've died from that Fallen Angel, but yet here he is." Replied Rias as she took a seat on the opposite couch to Issei's.

"Fallen Angel? What are you talking about?" Asked Issei, playing dumb. "Issei Hyoudou, do you know about Devils, Angels and Fallen Angels?" Asked Rias as she took a cup of tea from Akeno. She also nodded to the two people that entered the clubroom, Yuuto Kiba and Koneko Toujou.

"Uh, yeah?" Replied Issei. "Well, to make it simple we're devils." Stated Rias as she and the rest of the devils in the room released their wings. 'Hmm? Only one pair for all of them? That makes them pretty weak.' Thought Issei as he analyzed each of them.

"W-Wait, why are you telling me this?" Asked Issei confused. "Before I answer that, I need you to answer a few of my questions first." Said Rias as she put her cup of tea down. Issei looked around him to see that they were forming some kind of barrier, they weren't planning on letting him go and they were keeping their guard up.

"Now, tell me... How did you survive your encounter with that Fallen Angel?" Asked Rias as she narrowed her eyes. "I don't know, I didn't have an encounter with a Fallen Angel." Replied Issei looking confused. Rias got slightly irritated.

"Don't lie to me! We know that the Fallen Angel you went on a date with planned on killing you, so you must've done something to prevent that." Stated Rias as she crossed her legs. Issei was impressed by this girls boldness, she didn't even know who she was messing with yet she's so confident.

Issei sighed as he crossed his legs as well and cracked his knuckles. "Well you're certainly confident, Princess." Said Issei as he looked at Rias with serious eyes. Rias flinched a bit at this and the other members of her peerage got cautious.

"I see no reason to answer your questions, Gremory. So how about you convince me?" Suggested Issei before Kiba pointed his sword at his throat. "Kiba wait!" Ordered Rias as Kiba then put his sword away. Issei grinned at the Knights actions.

"What can I do that'll make you talk?" Asked Rias seriously. "I want to see your dedication, so how about you strip for me?" Replied Issei, getting everyone else in the room to get ready to fight. Rias looked at Issei disgusted.

"Hahahaha! Just kidding!" Said Issei as he laughed. Everyone was confused at Issei's actions, but decided to calm down for a bit. "I was just messing with you, go on then, ask away!" Added Issei with a smirk.

Rias hesitantly nodded and sat down. "S-So, how did you stop the Fallen Angel from killing you?" Asked Rias curiously. "Simple, I killed her." Replied Issei quickly. Rias was shocked for a moment but decided to continue.

"What are you exactly? You're definitely not human." Said Rias as she asked her next question. "Half-Devil, Half-Dragon." Replied Issei with a grin of pride. Everyone looked at Issei with shock, awe and caution.

"You're a devil? What household are you from?" Asked Rias curiously. "One of the Old Household's extinguished from the Last Great War, the Hyoudou Household. The very same one that killed Jesus Christ." Replied Issei as he stood up and revealed his ten devil wings.

"T-Ten?!" Uttered Rias with fear, the other devils were also affected by this massive power. Seeing their reactions Issei smirked as he retracted his wings.

"I believe that's all I will answer for now, I must be going." Stated Issei as he left the room of shocked devils.

*Underworld*

Sirzechs was drinking some coffee as he was going through some reports. Until he heard somebody knock at his door. "Come in." Said Sirzechs as he allowed the visitor to enter.

"Sirzechs-sama! I have urgent news!" Stated the Soldier that entered the office. "Hmm? What is it?" Asked Sirzechs slightly interested.

"We have received confirmation of Issei Hyoudou's origins, he is indeed a member of the Original Bloodline." Reported the Soldier. Sirzechs nearly spilled his coffee at the report, he then fixed himself and smiled. "It seems that Serafall will be getting a new Bodyguard after all." Muttered Sirzechs happily as a small magic circle appeared on his right ear.

Issei was walking back home as it was actually pretty late already. But as Issei was walking back, he noticed a few supernatural aura's at the church nearby. He could feel the aura's of Devils and Fallen Angels.

'Ah, so Rias has made a move on the rogue Fallen Angels...' Thought Issei as he continued to walk home. {You know, Nashetania is going to kill you for all of the things you've revealed today...} Stated Ddraig Honestly. 'Why do you say that?' Asked Issei in his head.

{Your arrogance has gotten the best of you once again. You not only revealed that you were part of the Hyoudou Household, but also that you were an Ultimate-Class Devil.} Scolded Ddraig. Issei pouted at this.

'Hey! I didn't think it would do any harm, I mean... So what if they know I'm an Ultimate-Class?' Argued Issei in his thoughts. {She probably sent a report over to her brother, Sirzechs Lucifer. Either they try and do something with you for the benefit of the Devil Race or they erase you.} Replied Ddraig sounding irritated.

'Let them try, I almost beat Ophis once. No ordinary devils can defeat me.' Thought Issei as he arrived at his home.

*The Next Day*

Issei was at school, looking outside the window of his classroom. He was utterly bored, until he was called by someone who entered his classroom.

"I'm looking for Issei Hyoudou." Stated a young man who was also known as Genshirou Saji. "Ah, Mr. Hyoudou please follow Mr. Saji here." Said the teacher, Issei sighed as he nodded and followed the young devil.

'He's the Wielder of Vritra isn't he?' Asked Issei in his head. {Indeed, but it seems he isn't awakening due to the fact that he was split into multiple Sacred Gears.} Replied Ddraig. Issei then noticed that he had arrived at the door to the Student Council Office.

"We're here." Said Saji as he opened the door. Saji and Issei stepped inside to see the Student Council President, Sona Shitori.

"Ah, thank you for bringing him here Saji." Thanked Sona as Saji nodded and sat down on one of the couches. "Please, take a seat." Offered Sona to Issei Hyoudou. Issei nodded as he accepted the offer.

"Issei Hyoudou, I heard from Rias that you were a member of the Hyoudou Household which killed Jesus Christ... Is that correct?" Asked Sona curiously. "Indeed it is, is there a problem with that?" Replied Issei as he asked a question.

"Not at all, in fact that is the reason you were brought here. To fulfill your duty as a Member of the Hyoudou Household." Replied Sona as she stared directly at Issei. This confused Issei as he never really had any duty.

"What duty?" Asked Issei curiously. Sona was about to reply until a female with some magical girl costume appeared from a magic circle.

"Your duty to loyally serve the Leviathan of course!" Answered Serafall Leviathan, one of the current Maou's.

THE END

Thank you guys for reading! I honestly had some lazy moments here, like in the date of Issei and Raynare. But I guess I'm just excited to finally get into the meat of the story, and we get there once Issei reunites with Katerea. Issei will also become the Personal Bodyguard of Serafall Leviathan for the next few chapters, so expect him to interfere with dangerous manners involving Serafall's sister, Sona Sitri.

Also please tell me what you thought of Issei and his family during and before the Last Great War, did you like how I implemented Jesus Christ into the story? And if you're wondering why I gave such an important figure In the Bible Eight Wings instead of Twelve, it's because in the church near my town there is a painting of Jesus with Eight Angel Wings.

Anyway, I hope you enjoyed and please do not hesitate to Review and give your opinion!

NEXT TIME ON DRAGON GOD OF LEVIATHAN

"Bodyguard?"

"Sorry, I'm afraid that this girl is under my protection."

"You dare touch me you low-class brat!?"

"You're interesting, Issei Hyoudou. But are you really going to loyally serve Serafall Leviathan?"
