Great demon king

It had been more than two days since the news of Eiji defeating the Sea God Poseidon spread to the ears of every supernatural faction. Although that man himself didn't seem to care much and would rather have fun with his woman.

I don't know who said it first, but the title "God Killer" was put on Eiji's head which made the human magician in every magician organization, people from the hero clan, and certain groups containing Sacred Gear, Holy Sword and Demon Sword users feel interested in him until many of them started to find out about him.

Especially a man who became the leader of a group called the Hero Faction.

The group is also actually affiliated with the world's most notorious terrorist organization, the Khaos Brigade.

But put that aside.

Right now, Cao Cao, the descendant of Cao Cao from the Three Kingdoms era who was the leader of the Hero Faction looked very happy after hearing the news about the human who managed to kill a god a few days ago.

"His name is Eiji Seiya, his race is human, has very strong power even though he doesn't have Sacred Gear? Killing one of the main gods of the famous Greek Mythology, Poseidon with a single strike? Everything, already decided.

"We should invite this guy to the Hero Faction."

"Cao Cao, none of us are against your decision. It's just that would the person in question be interested in joining our group?"

Perseus, the heir of the god spirit Perseus asked a reasonable question. Cao Cao understood, but he was very confident and said.

"He will. With such a powerful force and as a human, how could he refuse to join our Hero Faction that has the noble goal of ridding this world of evil creatures such as devils, fallen angels, and dragons?"

A blonde woman who had just finished watching Eiji and Poseidon's battle video on her cell phone raised her hand. Cao Cao nodded at the woman as if to let her speak.

"Cao Cao, I don't mind this handsome man joining our group. But doesn't he seem to be related to the devil? His appearance when killing Poseidon is also said to have something to do with devils."

"Who said that to you?"

That woman, Jeanne who carried the spirit of the Maiden of Orleans, Jean of Arc from the legend showed the devil-devil commentary on the video on her cell phone.

Cao Cao frowned, honestly he didn't really investigate other details about Eiji Seiya after watching his battle video and the information he got from the Hero Faction's intelligence.

I only know Eiji Seiya is a human without Sacred Gear, from his fighting style he seems to be a magician and that's enough for me.

"Georg, is that true?"

If it's about the information the Hero Faction got, Georg who is a descendant of Johan Georg Faust is usually the one in charge of verifying its authenticity.

Feeling everyone's gaze on him, the bespectacled man called Georg adjusted the position of his glasses slightly before saying.

"What Jeanne said is not wrong. Although Eiji Seiya is a human, a high school student, he also has two devil fiancés who are actually the heirs of Gremory and Sitri from the underworld."

Cao Cao's expression gradually became ugly, but Georg quickly continued.

"As for his appearance when killing Poseidon, he seems to have various abilities. One of them is to change his physiology into something devil-like although that has not been fully confirmed."

Hearing this, Cao Cao's expression became more favorable.

"If it's just one of his abilities fine! As long as he's human, I still want him to join the Hero Faction."

"What if he refuses?" Jeanne asked.

Cao Cao smiled.

"If he refuses then that man must have been manipulated by his two devil fiancés! He's also an evil being, I will personally eradicate his existence with my True Longinus."

The object he was referring to was the spear that suddenly appeared in his hand. With a dark blue colored shaft, golden metal decorations, a sharp arrow-shaped tip that rotated in a double helix pattern. Of the first thirteen Longinus created by the God of the Bible, True Longinus is known as the strongest Longinus.

Although he knew Eiji Seiya was so powerful that he could kill a god, Cao Cao who had a god-killing weapon in his hand was confident that he could kill the man if he refused his invitation.

"For now does anyone know his home address?"

...

Meanwhile.

In Eiji's house, which was beautiful and fragrant because there were many beautiful girls living there.

Eiji, Lala, and Peke were busy playing with the mechanism that Lala had just made with a little help from Eiji here and there.

Lala told Peke to install a bolt on a certain object attached to the corner of the gate of the house that had now been remodeled into a short passage to enter the yard.

"Is this enough, Lala-sama?" Peke who was flying in the air asked with a screwdriver in her round Doraemon-like hand. Eiji wondered how Peke could hold a screwdriver and even other objects like cookware since she also usually helped Asia and Grayfia in the kitchen.

Lala nodded and gave a thumbs up. "Enough! Peke, come back here."

"As you wish, Lala-sama. Excuse me Eiji-dono."

Peke sat on the chair next to him and Lala.

"...." Eiji.

"Eiji! It's ready! Would you like to activate Anti-Intruder-Man-Kun now?"

[That's a... nice name. As expected from Lala.]

Eiji nodded at the brightly smiling pink-haired girl. There was no way I could refuse her, nor could I comment on the name she gave.

"Activate it now. The sooner the better."

"Okay!"

Lala pressed the red button on the small device in her hand. Instantly, there didn't seem to be anything wrong with the gate of his newly renovated house.

But with his Rinnegan, Eiji could see through the 3D object and see that the new mechanism installed on the gate was already active. In addition to Alien science and knowledge, there was also the power of magic, chakra, and reiatsu mixed in. About 50 traps were set up in the hallway of his gate which should be strong enough to penetrate the defenses of a god-class creature.

Just because I'm bored and there's no protagonist who dares to seek trouble with me. I haven't even had the chance to try out my Zanpakuto unless I take the initiative to seek trouble with others. Me, Lala and Peke made crafts that would make many supernatural beings in this world probably tremble in fear.

"Eiji, do you want to try it? Although it's made especially for men, I certainly set you up as an exception and I can change it at any time." Lala said something dangerous to her future husband.

Do you really love your fiancé, Lala?

Although it's not enough to kill me, but I'm sure that man's anti intruder mechanism is capable of ruining my clothes.

¶{Isn't it just clothes? You're so reluctant...}

Miss System, you don't love your host either.

¶{...So what do you want to do to test it?}

This woman ignored his words and changed the topic by asking something else.

This was totally her style.

"There's no need for your fiancé to test her. Lala, we can let someone else try it." Eiji said to his pink-haired fiancée. Now that it was Sunday, besides them, there were only Grayfia, Asia, Momo and Nana at home. The other girls had their own business outside the house.

"Eh? But this mechanism is only made exclusively for men. Eiji, do you have any male friends?"

Now Lala said something rather embarrassing to him. Eiji thought, what about Basara? If he called that boy to play at his house now, something bad would happen to him, his beautiful aunt would definitely lose her favor on him.

Everything he did two days ago would be in vain!

That goddess's ass, ah...

What about the protagonist Rito?

¶{Admit it you don't have any male friends. All the ones you've mentioned up to this point are male protagonists who are the targets of your green hat operations. Can they be considered real friends? You're not very close with Rito either, and that boy doesn't consider you a friend.}

Miss System, you're so cruel.

Eiji began to feel Lala's innocent gaze hurt him somewhat.

"Lala, didn't Lavinia come to the house this morning? Has she gone home?"

Lala shook her head. "No, I heard she specifically came to teach magic to Momo and Nana."

"Lavinia is a woman by the way."

Eiji looked at the pink-haired girl flatly. The girl giggled, oh was she joking?

"Never mind. I'm sure this mechanism works fine. Deactivate it on men who have something to do with the women around me. Turn it up to low to high for people I don't like or strangers who might have bad intentions when they come to the house."

At first he wanted to ask Lavinia to call Tobio to come here. But that would be too intentional in Lavinia's eyes, so it was better to cancel the plan and let nature take its course.

After cleaning up their belongings in the yard, and Lala turned on the TV to watch Magical Kyouko in the living room. Eiji remembered wasn't that girl also one of the heroine? The girl was somewhat similar to Momo except that her hair color was black and she was a half-human half-alien hybrid girl who could create fire or something.

When he was a little interested in watching with Lala and Peke, his cell phone happened to ring which made Lala look at him curiously.

Eiji looked at the caller's name and said, "It's Run."

"Run?"

"Yes, she called me during her working hours as an Idol."

Just like Ai, Run is also now officially an Idol and the girl is just as talented as in her original work. She has created four love-themed songs so far and the songs are quite popular although it's still a long way to go to beat the popularity of Ai's latest song which if I'm not mistaken is titled "Idol".

Speaking of Ai Hoshino, he had completely forgotten about the girl because of some plot that happened before. Eiji was a little worried, he was neglecting that girl too much!

After solving the problem of Run suddenly calling, I really need to go see that star-eyed girl and arrest her!

"Hello Run. What's wrong? You're calling me at this hour. Lala and I are watching Magical Kyouko in the living room right now."

"There she is!" The green-haired girl on the other side of the phone shouted.

"....." Eiji and Lala fell silent. What was wrong with this girl?

"Eiji! Please help me and Ai! We, we're now at Magical Kyouko's studio!"

"Yes? Why are you two there? Are there bad people looking for trouble with you guys? Don't worry, I'll come there and beat them up."

With the Master-Servant contract that Run also had, Eiji could know the exact location of the girl and could teleport there right now. However, the green-haired girl interrupted him and said.

"No! Eiji, that's not it! There are no bad guys here!"

"Then why do you sound panicked?"

Eiji was feeling a little thirsty now, he saw Lala holding a milk bottle... The kind Lala pushed the bottle of milk to him and he drank a little.

"It tastes good. Thanks Lala."

"Hehe~" After laughing, Lala also started drinking her daily milk while watching Magical Kyouko. By the way I could see the heads of Run and Ai who were hiding backstage from the TV screen.

Those girls are really there?

"This... The director at the agency asked us to collaborate with the director who aired the show Magical Kyouko to play songs and roles in the show."

Eiji felt he remembered something about this plot in the original work. But with the addition of Ai Hoshino, this plot clearly changed and became something else.

"Yes yes, then? Is the director a pervert and asked you to wear very skimpy clothes? I'm going to kill him."

"No... Eiji, why did you even think of such a plot? Me and Ai are still wearing more or less the same clothes as our Idol outfits."

Run, you don't understand. Usually in this kind of plot. There's more chance of the director or whoever forcing the pretty girl to show off her skin and take advantage of her innocence.

I'm just asking just in case.

"If that's not the case, that's fine. Get to the point, what do you need from me, Run? Just tell me, I won't refuse as long as it's not a weird request."

When Eiji said that, he was actually a little regretful because what happened next was...

"If there's a problem, I solve it by burning!! Explosive Heat Girl Magical Kyouko Flame!! I'm Kirisaki Kyouko, a descendant of witches, who's in the second year of high school, and I'm very busy being bothered by love."

"With the power of love, I will defeat the Demon King who hurts innocent people!"

"My friends, witch Ai Hoshino and witch Run. Will you two help me?"

The beautiful black-haired and violet-eyed girl dressed as a witch was holding a wand, a real fireball burning at the tip of her wand. People watching the show thought it was fake and just a visual effect.

Ai and Run who were also wearing magical girl outfits looked at each other with quivering lips as they stared at her.

""Yes! Magical Kyouko, we will lend you our powers!"'

The girls shouted at the same time.

Eiji felt he was too soft on his women. Otherwise, there was no way he would have agreed to replace someone's role as the Demon King on a television show watched by millions of people in Japan!

What kind of plot is this?

¶{Pfft!!}

Miss System, are you very happy to see your host become like this?

¶{I am... Hahaha! Just do it, it's also a plot after all. You will increase the heroines' favorability and get rewards from the system after going through this plot.}

¶{So get excited my host! Show off your acting skills to everyone watching!}

Well this actually wasn't too bad. The Demon King outfit prepared by the event team wasn't an ugly Demon King either. This is a Demon King usually seen in Korean novels, a Demon with a handsome face and his outfit consists of a black noble-style robe that is somewhat tattered to depict him having just woken up from a long sleep.

His white hair and natural red eyes don't help either, it makes him look like a real Demon King although that's not wrong since he's in Varvatos form!

Now to follow the script, he took the initiative to display the same black aura as the Demon King on his body. He only displayed it visually without putting any power into it.

Otherwise, I'm afraid it would hurt the three girls who were pretending to be Magical Girls in front of him.

"Defeat me? With just the three of you?"

"In all of heaven and earth, I am the only one who is honorable. As a great Demon King, I say you humans are overconfident."

"Know your place!"

!!!

In front of everyone's eyes, the event stage became more realistic with the sight of the Demon King's castle and the Demon King himself sitting on the throne. He looked down at the camera while uttering words that were so arrogant and mocking that it made the people watching gulp, especially the women who felt their panties get a little wet.

Truly worthy of being a great Demon King!

This actor animates the character he plays!

Kyouko, Run, and Ai were also stunned.

To be honest when she first met Eiji, Kyouko had a crush on the handsome man's appearance. However, she didn't expect the girl Run invited to be the same Eiji whose inner voice she often heard.

When he agreed to help her in this event, her liking for him increased. Not only that, when he showed his power as well...

Kyouko's eyes lit up, with Ai and Run singing behind her to boost her power. Or so the story went, the fireball at the tip of her staff was getting bigger.

"We won't know until we try. Demon King, I will show you the power of humans."

"We humans are not weak!!"

"Extreme Explosion!!!"

The audience of the show including Lala in front of the TV watched with their mouths open as this scene became too big and real.

Sitting on the throne, Eiji simply tapped the armrest with one finger and instantly a purple magic circle appeared in front of him. From within the magic circle, a 50 meter purple fireball comparable to Magical Kyouko's fireball was shot out.

*Boom!!!*

The two attacks collided and created a huge explosion.

The spectators could see Magical Kyouko's clothes being blown away along with the smoke around her.

When the smoke of the explosion cleared, Kyouko had sweat dripping down her forehead because it was the first time she had used that much power and she was a little tired. Even so, she was excited! Sure enough, Eiji was as strong as she knew from his inner voice! That's why she didn't hold back.

Seeing Magical Kyouko smiling even though she looked exhausted after using high-level magic, the audience in front of the TV cheered for her to defeat the Demon King.

However, there were actually many girls or adult women watching the show who were also cheering for the Demon King for him to defeat Magical Kyouko and her friends. This Demon King's good looks were even better than those famous male artists.

How could they not be excited?

This is the best Magical Kyouko episode they've ever seen!

"Sister, is it just me or does the Demon King fighting with Magical Kyouko look like your boyfriend?"

"...."

In front of the TV in her apartment room, Nodoka came to play and they happened to be watching Magical Kyouko while eating donuts. Mai doesn't have to worry about her weight, she's been eating a lot of sweets lately which makes her younger sister jealous because she never gains weight.

But put that aside.

"Nodoka, how do you know my boyfriend's appearance?"

"Ah... That..." Nodoka remembered that she kept her meeting with Eiji a secret in the bathroom. Seeing her older sister looking at her suspiciously, she knew she couldn't hide it anymore.

Back at the studio airing Magical Kyouko where the crew and the show director themselves had no idea how the inside of the studio really became the Demon King's magnificent and terrifying castle. Regardless, the professional director told the cameramen to shoot!

Ai Hoshino and Run who were singing the sountrack were also glowing with a pink and light green aura on their bodies. Unlike Run who knew this must be a visual effect created by Eiji, Ai was actually surprised because it was her first time seeing a magic show of this magnitude even though she knew Eiji was a witch from the start.

As a professional, she still did her job to sing while watching Eiji and Kyouko who kept fighting and shooting magic at each other.

With panting breath, Kyouko looked at Eiji doubtfully because... Do you still remember the script? Eiji, you must lose!

Let me win!

Eiji who noticed the girl's gaze remembered he was the villain and the other party was the protagonist in this event. So he pretended to cough and vomit blood as if he was also injured from continuing to fend off Kyouko's fire-based magic attacks which were actually very weak.

He was still sitting on his Demon King throne and staring at the girl in annoyance.

Kyouko who saw this gripped her staff with both hands and immediately said her lines.

"Demon King, you will lose! Evil will always be defeated by the light of justice! With the hopes of the people who trusted me, I will not let them down! I... I Magical Kyouko will definitely win and bring peace to this world!"

This dialog... Eiji felt a little embarrassed living here. However, his acting skills were not weak either. Under the gaze of people who were moved and crying to hear because they heard Kyouko's words. No, it must also be because of the soundtrack that Ai and Run were singing in the background.

He smiled wickedly like the Demon King even though he was really one. He sneered at Kyouko and looked at her with disdain.

Wait, that disgusted look was too much, right? Kyouko silently complained, but she was a little nervous when she saw Eiji get up from his throne and walk towards her step by step.

This isn't in the script!

Are you improvising again?!

Under the dumbfounded gaze of the director and the audience, they saw the Demon King lift Magical Kyouko's chin with his hand.

That Demon King smiled and made Magical Kyouko blush!

"D-Demon King, what are you doing? We're fighting! I'll beat you!" Kyouko didn't what Eiji was playing at, but the smile on the man's face was deadly for a face lover like her.

Eiji was more handsome than Ikemen-san.

Speaking of a boy with brown hair and green eyes who was one year older than Kyouko, that boy was also watching and staring at the two with an ugly expression on his face.

His Kyouko-chan was touched by another man!

Eiji honestly didn't remember there being such a character in the original work but whatever, he looked at Kyouko's beautiful face and said something that surprised all the spectators.

"Your name is Kyouko, right? I've already decided."

"Decided? Decided what? Demon King, we must continue the fight!" Kyouko couldn't cry or laugh, the improvisation of this script had gone too far but the director didn't seem to complain either. The old man actually gave the two of them a thumbs up.

"You want peace to this world, right? There's no need to fight. I the Demon King will surrender and in exchange I want you to be my woman." Eiji said that and everyone including the audience fell silent.

"Ehh!!!"

Kyouko's face turned red and screamed, this... This is still acting, right?

This script is wrong!

Why did the climax become the Demon King's confession to Magical Kyouko?!
