Kisuke wasn't done yet and pulled his hand out from the wall before muttering, "5th Gate: Acceptance."
Kisuke knew that he was outclassed by Chaos in almost all aspects and if he wanted even a little bit of a chance to suppress him, he needed to use everything he could manage, focus it, and hit him where it hurts the most.
Stepping on the wall and pushing against it, Kisuke instantly made a big crater in it and shook the entire structure of the Dungeon as he launched himself toward the headless Chaos.
Kisuke positioned his sword horizontally and swung it with all of his momentum and strength when Chaos came within his reach. The headless man moved his arm to block Kisuke's blade but it did nothing except allow himself to be cut along his torso. The cutting power behind his sword was so strong that it left a deep scar along the walls of the dungeon.
But despite this, Kisuke couldn't be happy as he could see small tentacles emerging from the bisected part and reconnecting themselves. Kisuke reached out his free hand and pointed it towards Chaos, "Hadou no 88, Shin Hiryuu Gekizoku Shinten Raihou (Flying Dragon-Striking Heaven-Shaking Thunder Cannon)!"
A modified Kidou that truly encompasses the majesty and pride of a Dragon thanks to the experience he got from the real thing. Instead of a normal blue gigantic blast of Spiritual Power and Ki, it took the shape of an Eastern Dragon and was mixed with his own bloody aura giving it a deep red color. The blood 'Dragon' swallowed the bisected Chaos whole and attempted to incinerate him into nothing inside its 'stomach' while also pushing him deep into the Dungeon's wall.

On the outside, the battlefield is only heating up now with Issei, Vali, Crom, and Sairaog in the lead against the more than five thousand Deities that suddenly teleported on the surface. Although they were still weakened, even if only by a bit since Chaos removed the poison that Kisuke had given them and most of them already had the power to fight back.
"Hey... Isn't this a bit too much?" Issei asked while in his Bishop Promotion form and blasting the cannons behind him almost indiscriminately.
Vali kept reducing and absorbing the power of those he touched until the victim Deities couldn't even maintain flight. But before his stunt earlier, even if he could recover his energy, his body was still strained, "...He's not expecting us to deal with all of them by ourselves, right?"
"What's this? You're actually agreeing with Issei? I thought you'd be more like that?" Sairaog turned to them after splitting the head of an enemy and pointed towards a certain direction where a man with blonde and black hair is rampaging gleefully while taking on the attacks of the Deities.
"Even I have my limits," Vali replied, "Well, just let him release his pent-up frustrations. His training has been paying off recently but there was nowhere to vent. I assume he could be classified as the third Heavenly Dragon just from his strength alone."
[I agree.] Ddraig also spoke up, [Seven years is not a long time by Dragon standards, yet he improved tremendously during that time.]
[But that also means the future is that grim. Such pressure to push a powerful Dragon beyond his limits... The Evies won't be an easy opponent.] Albion also added.
'Is that why Dragons have always stood at the very top of the food chain?' Sairaog asked himself after hearing that, 'When there's a stronger species, the Dragons automatically adapt and vie for the top. Or maybe, it's due to the enormous vacuum that Great Red and Ophis left.'
If his guess was correct, then that would explain the sudden explosion of strength among those who are related to Dragons, 'In any case, I can't be left behind!'
Meanwhile, the rest of Team DxD was behind them giving support and long-range attacks as a form of containment. They only have one goal today and that is to keep the enemy Deities from interfering in the most important battle.

Kisuke wanted to continue his assault but he had to stop momentarily to cool down. If not, he'd only be shooting himself in the foot.
As he tried to calm down the turbulent energy within him, Kisuke carefully watched Chaos and saw him effortlessly regenerate everything that he did to him, 'That easy? As expected... I have to anchor his existence somewhere first before I can think of killing him.'
However, Kisuke could also see that Chaos was not left unscathed. Although he looked fine, there's something about him that's a bit weaker from their first encounter, 'Alright... Time to push him to the edge.'
Kisuke pointed his sword forward and his red hagoromo from his Shunkou wrapped around his blade as he muttered, full of killing intent, "...Ban...Kai."
From the five 'eyes' behind him, five mechanical fingers with a blade on their tips slowly emerged. Soon, red, shining outlines drew themselves on these giants and menacing fingers and red strings of energy materialized around Kisuke himself. As his aura exploded multiple times over, he continued, "Kannonbiraki Benihime Aratame..."
Using the power provided by his Shunkou and the path that the Hougyoku left behind before it disappeared, Kisuke unlocked a new form of his Bankai that seems to have fused with him instead of normally materializing.
At the same time, however, Chaos also finished regenerating as if nothing happened to him. Except, he has this incredibly pissed expression and he turned his deep dark eyes to Kisuke. He ignored this new and strange form and with a pissed voice, he uttered softly, "You pest... Die in ignorance."
Kisuke had been stronger than ever, but unfortunately for him, his lack of complete information regarding Chaos finally bit him back... And Chaos bit hard.
He didn't know when, but Kisuke suddenly found himself floating in the darkness where there was nothing. He couldn't tell if he was standing or falling. He couldn't tell if he was breathing or not. He couldn't tell if he was blinded or if it was just the absence of light. He couldn't see his own body and feel his own aura. It's as if his mind alone was transported to a very dark world.
However, he could feel dread and just now, he had a strange feeling that his left flank entirely disappeared despite not having any senses. In all of his life after his reincarnation, death had never been closer.
