The barrier around them collapsed like a tall broken pane of glass crashing downwards and Chaos couldn't do anything about the collapse of his own body until there was only a five-inch wide eyeball with a red pupil surrounded by a thick dark mist left.
Kisuke's smile disappeared when he saw this and immediately tried cutting it into two. However, his sword only went through it as if he slashed at nothing. He then used Benihime's modification ability to at least cut it open but neither Kisuke nor Benihime couldn't 'find' this eye. It's as if it's not existing at all.
[Cease your futile attempt.] Kisuke heard Chaos' voice inside his head, only this time, in a much calmer or even apathetic tone, [You've won. I can no longer proceed with my plans.]
"You discarded everything and only left the most essential part?" Kisuke guessed that this is the real Chaos and the Chaos earlier is just a manifestation through 'eating' various things endlessly.
The eye stared down on him but Kisuke could only feel a bit of irritation from it akin to splashing juice on his new clothes, [You've won but I'll continue living and return to get what's truly mine while you'll be remembered as someone who sacrificed himself to fend me off.]
"Sacrificed myself? I'm sorry but I'm not heroic enough to do something so selfless."
[Stop pretending. I know that the moment that form of yours is broken, you won't be able to keep yourself alive anymore. After all, I ate more than half of what makes you, including the very essence of your existence.]
Kisuke became silent. He already tried pushing his regeneration but there was no response from it as he expected, 'There's no need to regenerate because there's nothing missing. I, as I am now, am 'complete' that the regeneration isn't kicking in.'
And as powerful as his Bankai is, all modifications it has done were just temporary alterations and reality will correct itself once the influence of his power disappears. Benihime knew this so that's why she was more obsessed with the desire to kill Chaos and taking back what was stolen than Kisuke. And now that she finally realized why Tiamat and Kisuke repeatedly affirmed that Chaos couldn't be killed, she became a bit desperate, [Oi, Kisuke! You came here knowing a way to eliminate him, right? If so, do it now! You're already at your limit and he's about to leave!]
Kisuke ignored Benihime and replied to Chaos, "Good job noticing that, but aren't you too confident? Who knows, I might just pull out a miracle and suddenly cut you."
[You of all people know that for a miracle to happen, there has to be a basis for it.] Chaos started floating and the space above them began quivering. Ophis, Flanna, and Lilith were trying to keep it closed, but Chaos' return to the void was the natural order of things and couldn't be stopped, [You had two chances for that miracle to demonstrate itself. One is already long gone and the other one is still sleeping deep within the Dungeon, both of which are already far too late to utilize.]
Chaos was so confident that nothing would be able to touch him that he revealed the only things that could work against him.
Kisuke, meanwhile, completely agreed with his confidence. After a few moments of observation, he guessed that he was in a state where the boundaries between real and unreal were blurred to the extreme. If he were to continue his conjecture, Kisuke speculated that Chaos' existence itself was deeply ingrained in the void where he's residing most of the time and without cutting this connection, Chaos would just return again and again.
However, this is something that Kisuke already expected from studying the beasts of the void from long ago. Since Benihime kept shouting at his consciousness, it was about time to pull out his last card, 'I didn't really want to leave my fate to others since I already died once by doing just exactly that... But I guess I don't really have a choice anymore.'
Kisuke snapped his fingers and the quivering space stopped and five golden lights suddenly shot up from the ruins of Orario to the vast expanse of space before a thin golden barrier connected the lights, "Negacion."
Chaos looked around and felt the space around them closing off. The barrier was even stronger than what he'd erected earlier and was designed to secure a perimeter. However, he could also see that it wouldn't last long as its strength is proportional to its longevity, [What's the point of this? To keep me here longer? Will you attempt waking up Null? I'm sorry to break it to you because even if you could open her eyes, she'd just destroy everything in this world while birthing more monsters. She's not exactly in a state where you could reason with her.]
If Chaos had a head, Kisuke would've been able to see him sneer. Nevertheless, he ignored his reaction and pulled out a dagger that was somehow kept safe.
Benihime always wondered what this dagger was and why it gave her a very bad feeling, but only after Kisuke pulled it out of its hilt did she finally understand what he had been hiding, [Kisuke!!! You bastard!!!]
Kisuke only chuckled at Benihime's uproar and said, "Just think of it as my ticket to save myself."
[Kuh!!! No!!! But still...] Benihime couldn't make up her mind, [AAHHHH!!! I'll cut you up later!]
"It's true that I can't do any miracles, but creating the foundation for one? I'd like to call myself an expert on that." Kisuke then let go of Benihime and his Bankai was withdrawn. As soon as it disappeared, the strings that were keeping Kisuke together also disappeared and as an extension, his Shunko was also dispelled, leaving him in a state ever closer to death.
Chaos thought that he'd already given up, but the smile on Kisuke's half-face didn't disappear as he continued to broadcast his intent, [Say hi to your new neighbor, Benihime. Descend, Tiamat!]
The dagger in his hand melted into a black substance, but unlike Chaos' black goo, it was Tiamat's black sea. It then reformed itself into a longsword with a soft greenish sheen on its double edged blade and the pommel was reminiscent of Tiamat's Dragon horns.
Chaos knew what that longsword's existence meant and hurriedly flew up while desperately trying to open the space, [HOW!!!?]
Without the Shunko's and Benihime's support, Kisuke immediately lost his focus, and his senses rapidly dimmed as he plunged down. But with all of his remaining strength, he threw his longsword and saw it hit the bullseye before losing consciousness, 'I hope this won't be the last time I'll be sleeping.'
