Within the barren wasteland that only screamed and soul of the dead roam the land. Issei along with Jeanne arrived in the realm of the dead to find Hades and enslaved him. He would be unaware that his being manipulated and would allow Issei to find the rest of the Alliance of hell.
"So this is the realm of the dead? Its really like how I imagine it but much worse."(Jeanne)
"Be careful since its hard to find you once you wander off. Here grabbed my hand."
Issei held out his hand to Jeanne who blushed from the gesture but accepted it. She was embarrassed and happy at the same time causing to be flustered.
Seeing her reaction made Issei chuckled then spread his senses to find Hades and to ensure no one else would interfere. He sense a single person inside the temple and confident it was his target.
Issei felt from the distance that drawing his attention. There's a place that was calling him and thought of going once he get Hades. He turned to the flustered Jeanne then said.
"Alright hold on tight. We should arrive in Hades temple."
Jeanne only nodded as both of them swiftly move towards the temple while holding hands. She was struggling to keep up with Issei speed who notice her struggle decided to princess carry her into his arms.
She panic from the action becoming beet red as Issei used his physical strength run through toward the temple. Issei could have just used teleportation but he unconsciously flirted with Jeanne. He didn't even notice it that his stealing another maiden's heart.
"W-What are you doing? I can run by myself, Ise-kun."
"Hehehe but I thought you'd like it. Hey how about we go on date?"
"Whaat are you saying!? You already have so many lovers though!"
"Hey like I said I'm a harem king and especially now I'm partially a dragon as long I set my eyes on a pray I won't let them go."
Issei whispered into her ears causing shivers throughout her back. His personality becoming more stable as time goes on and the newly purified bloodline inside him had reshaped his mindset. Unbeknownst to him, it was the effect of being [Guider] which he would soon find out.
"A-Alright.."
"Great! Just tell me where you want to go then I won't hesitate to bring you there."
Issei gave a wide grin while Jeanne felt happy seeing the smile. His divine presence causes her soul to feel blessed. Few minutes passed by and finally arrived in the temple where inside was Hades sitting on his throne surrounded by grim reapers.
"How can this be!? Why has those bats and crows been destroying my plans!! Have any of you dare betray me!!"
He released a horrifying deathly aura quivering the grim reapers as it was pressure from one of the time strongest in Draconic Deus. Hades has growth frustrated from his lost contact with rizevim and recent interference of the devil. He couldn't moved without being directed to him.
Hades felt like he was in someone's palm since every time he tried planning it falls apart. His last chance was getting contact with Nyx and Erebus along with Angra mainyu but Issei had already sent Azi Dahaka, Apophis and Crom Cruach to deal with them. They would gladly fight them since in the previous timeline all of them was dying to fight them.
He provides them a special seal for each of them. It would be a waste to kill them and making them slaves is a much better punishment. Issei still suspicious of why the dark apostle didn't try contacting them put it aside. The location of the old devil faction still unknown which leaves him empty-handed in information.
"You lot call Thanatos and tell him to arrive quickly as I have a task for him."
Sending one of the grim reapers, Hades rests on his throne slamming his hand causing a fissure of cracking on the ground. He was ignorant that Issei and Jeanne were observing him from above.
"What are you planning anyway Issei?"(Jeanne)
"The date or Hades?"
"Dat-I mean hades! What are you planning to do with him!"
Issei teasingly smiled while enjoying Jeanne's flustered state as she adorably tried to hit him. They were surrounded by a tier of magic concealing their present. He didn't use [Nihility] as it wasn't necessary and only did it for training.
"Hehehe Alright I'm going stop but you do you looked cute pouting."
"Stop being meanie Issei and tell me."
"Well I thought killing or sealing them would be a waste of strong fighter. I planned to just enslave them since it's a better punishment for them."
"I see that does explain it since Hades is one of the strongest and other primordial who allied with him can provide support."
"Exactly! Anyway, I think Thanatos just arrive. Well, this will two in one huh?"
They both resumed watching as the newly arrived grim reaper with a much thicker and pure aura than the rest of the grim reaper appeared. Issei was surprised that he came since Thanatos was known to ignore hades request.
"In what reason you summon me, Hades?"
"Watch your tongue, Thanatos! I am not tin he mood with your antics for I have a task for you."
"And what would that be?"
"Thanatos my task is fo-"
Before he could finish his words, both felt space distorts and trapped in the powerful barrier. Hades quickly summoned his staff while Thanatos his scythe.
"Who dares intrudes in my domain!?"(Hades)
"Well for a host your quite bad. You hadn't offered me a single refreshment."
"Show yourself!"(Thanatos)
"You two are surely blind."
They couldn't shake the feeling of danger despite being one of the strongest. Both turned to see a young man with long white hair wearing a red jacket and baggy pants. His overall aura was strange as it didn't gave any indication of power but still exude danger.
Issei chuckled sensing their stiff aura, he had left Jeanne deal with the other grim reaper. The two gods were ready to attack any time if he took a single step.
"Mortal tell me your reason for coming here."(Hades)
"Quite simple. To enslave you."
Issei used a quick step called flash step appearing in front of the two gods who instantly countered with Thanatos slash his scythe towards Issei who easily caught it between his fingertips shocking him since it had the power to easily absorb a soul.
Hades who took a step back summon dozen of magic spells then used sealing magic on Issei but was shocked that it instantly shattered while the blasted magic spell was absorbed in a black sphere. Then Hades was surrounded by the black sphere getting hit by his own attack.
Issei who recently unlocked Abaddon's power of the hole was convenient to lessen his use of energy. Furthermore, his hole could double its power due to the influences of Boost. He was a literary walking cheat at this point.
Thanatos was astonished from the attack but terrified when he couldn't even budge his scythe from Issei who turn emotionless towards him. He then burst aura to the maximum causing Issei to loosen his grip letting the grim reaper do a clean slash on his head.
Yet to alarm when the head didn't even fall and the wound on his neck was instantly healing exuding black flames. Issei held out his palm creating a magic circle foreign to him then felt his consciousness fading.
"Eternal Enslavement."
Casting an enslavement spell, Thanatos was now Issei's servant for all eternity even if he somehow dies then both of them will perish. It's a spell that essentially reprograms the psyche of anyone as long the person is weaker than the caster. They won't be mindless slaves but will only be utmost loyal to him.
"You are one of those bat huh!? Well, I congratulate you for wounding me but this will be your end!"
Issei lazily glances where Hades was healing himself due to the wound he sustains. He was increasing his death aura to maximum but Issei remains bored. Hades was infuriated by how his opponent dared to be so arrogant.
He summons a much stronger spell while used his divinity to increase his strength. Issei did the same summoning destruction bullet countering each of them. The blast causes everything to crumble to dust then in flash Issei appeared behind Hades slamming him into the ground.
"Well then let me turn you into my slave."
Hades didn't even know his assailant was and only felt utmost loyal towards him willing to do anything to please him. Not in that way perverts!
