It became a staring contest between Kisuke and Chaos for a single moment before the both of them disappeared from their spots and a clash of something akin to metal rang out not far from them. Such clashes then continued on for some time.
Those who were below a certain level could only hear the sound of the clashes produced and couldn't even see the figures of the combatants.
But to those who were involved, it was like a slow-mo movie playing out to their senses with each movement being caught by the other.
Chaos would reshape and harden his body to his will to attack and it would look like he has at least ten to a hundred arms in varying instances. Kisuke would block them using his sword and the five 'fingers' around him, but even then, multiple hits would still go through his defense due to their sheer numbers and speed. To make matters worse, some of these attacks also had 'Devour' mixed in so it was additional pressure and focus that Kisuke needed to commit to accurately figure out which 'arm' had this. And in his current state, any additional injuries only brought him closer and closer to actual death.
But although Kisuke was at an extreme disadvantage, his strange ability was actually sending a wave of panic through Chaos, which became obvious with his apparent impatience. With each moment, five invisible knives would cut open his 'arms' and stitch them back up. The next instant, these arms imploded into themselves and Chaos had no way of repairing them like he should've been able to easily do. Without much choice, he had to recreate the destroyed 'arm' to keep the numbers up, but it was taking a toll on his reserves even if he had an absolutely massive amount.
And despite being confident in his 'unkillable' nature, Chaos was always the first one to disengage from their clashes while Kisuke, who's on the verge of death, would follow him like the madman he is.
'This guy... Doesn't know how to fight.' Kisuke came to this realization after having a deeper understanding of his opponent from their clashes. He was another being that was born into power and didn't really think about surviving nor having a natural enemy, 'Despite his overtuned specs, he can't utilize most of them so I shouldn't be worried about the small nicks he's doing. Big techniques, however, are still a problem which means I can't give him too much space for something like that.'
'But if he ever repeats that one from earlier...' A strange glint surfaced on Kisuke's remaining eye as he modified the 'arms' he touched.
Chaos gritted his teeth and tried getting away. With each clash, the cuts and stitches were doing worse and worse damage to him as his 'arms' didn't just simply implode, 'He's actually poking holes in me now! My power is leaking and I have no way to easily repair them! Just what is this ability!? And how come a mere mortal like him has something like this!?'
Chaos tried mixing up his attacks with other techniques, but the detestable 'cut and stitches' would cause them to fail. As he audibly clicked his tongue, he thought, 'I can't do anything else aside from that. But that would leave me depleted and I would have to go back up to replenish.'
Nevertheless, after watching the crazed Kisuke as he hounded him without any regard for his own life, a tiny, tiny bit of fear finally sprouted in his mind, 'But if I can remove this variable... It's a shame, but I will have to call down my children to clean up the rest of them.'
Coming to a decision, Chaos immediately acted upon it.
He sped away and the 'arms' all around him retracted as his whole body turned into a black mist. Along within it was the same blood-freezing aura that almost drowned everyone and it was way worse since he's doing it now on the surface and in everyone's view.
Chaos' body expanded rapidly and engulfed the whole area, "Try surviving this again.", however, he thought he saw Kisuke grin when he was about to be swallowed by the darkness that almost killed him earlier.
A sphere of darkness was instantly created so that no outside interference could influence the inside.
Yoruichi and the others got worried that he got swallowed once again, but the former knew what Kisuke was capable of and how he dealt with things he already saw once.
And as she was expecting, five cuts were created on the surface of the sphere before it was immediately stitched up. A second later, the perfect sphere turned wobbly before it collapsed back into Chaos' figure, but this time, his body was partially melting as he coughed out black 'blood', "...Y-you! How!?"
Kisuke, who just stood still and came out perfectly fine, gave him a large grin, "Even the most terrifying guy I know wouldn't carelessly touch me twice."
No matter how inexperienced Chaos was, he finally realized his opponent's ability, "Modification through understanding?" Chaos' initial guess of him concocting specialized poisons was very wrong.
"Great job, but sadly, no prize for you." Kisuke disappeared from his spot and reappeared in front of the still disoriented Chaos, "I'm too poor for that."
Chaos hurriedly solidified his limbs to block all six blades that were coming to him, but as soon as he touched them, the neverending cuts and stitches appeared once again, imploding his defenses into nonexistence. He instantly recreated his limbs and while doing so, created even more. However, it became very obvious that he didn't have the same vigor he had before.
Chaos then turned his attention to his home and attempted to call down his children to push back and smother Kisuke using their sheer numbers. In that instant, however, there was a lapse in his concentration and Kisuke found an opening to dismember him into several pieces.
Kisuke's opponent didn't actually mind this since he was confident that Kisuke hadn't understood enough of his very essence to make any direct modifications on him. What he was wondering and what caused him to be cut down, however, was that there were no responses from his children. Or more specifically, he lost his way of communicating with his 'home' and he only realized it just now. Chaos couldn't even open the path to the void, as if someone was holding the door tight. He could pry it open, but he would need a lot more effort.
Kisuke, on the other hand, guessed what was on his mind and said, "Why did you think I didn't have those Dragons with me when they can freely cross the boundaries between dimensions?"
In other words, Chaos's home was locked from the inside by the two bigshots and his children were trapped inside along with them. No matter how numerous they were, they wouldn't be able to do anything against the True Dragon and the Dragon God, at least not for a very long time.
