A vein popped on Chaos' forehead but he reigned in the rage that was boiling deep within him. He's not stupid enough to fall into Kisuke's pace over and over again. Ignoring what he'd just said, Chaos continued, "Did you really think that just because I'm busy here, you can take me on all by yourself? If that's not arrogance, I don't know what it is, since you're not a fool."
Kisuke observed the situation more and found that a black tentacle coming out of Chaos' leg is attached to the embedded person's belly and from her, black veins spread out through the entire Dungeon, "That's not Tiamat... Is it?"
Chaos smirked and began muttering, "Ah~ Right. You managed to kill Tiamat against all of my expectations. What should I do~? I'm very tempted to wake her sister up and see what she'll do~."
Kisuke's neutral expression changed to that of a frown, "...Sister?"
Chaos looked down at the woman and proceeded to step on her head, "Yes. Arguably, the real 'Mother'. If Tiamat created order, Null created the substance." As he ground his foot on her, Kisuke could see the pleasure on Chaos' face and almost reeled from it, "But for such powerful beings, they were too naive. I had a great time as their advisor. Ahh~ Those were good times..." At this point, the twisted smile on Chaos is the worst that Kisuke had ever seen, "Corrupting them and slowly leading them to their demise as I gobble everything up... I want to relish that experience once again."
All of a sudden, a whistling sound pulled Chaos from his nostalgia and he stretched his left hand to catch the crimson arc that was aimed directly at him before crushing it and reducing it into motes of light, "What a rude fellow."
Kisuke lowered his sword and said, "I apologize. I saw something disgusting and felt the need to destroy it."
The disgusting smile from Chaos' face finally disappeared as he faced Kisuke once again, "Looks like you won't stop bothering me until I give you a lot of pain."
The answer that Kisuke gave him was another swing of his Benihime. Similar to before, Chaos just casually dealt with the sword arc that's enough to injure a strong God by slapping it away with his bare hands.
Naturally, Chaos wouldn't just passively defend himself. Although he didn't move from his position, Kisuke suddenly felt small tremors on the ground and the walls and immediately jumped up. In his previous position, he saw numerous black tentacles that attempted to skewer him multiple times.
"As I said, your arrogance is the cause of your death." Chaos spoke while sending more tentacles toward Kisuke, "This is my domain and you have no say in it."
Kisuke didn't say anything back and just defended himself. He would attack if there's an opening but overall, his goal is to maintain the status quo, 'He also doesn't want to push me harder than this. That would mean that he's on a crucial part and I could potentially interrupt him.'
Kisuke knew that he had to interrupt him, however, he didn't know how he should be interrupted. As he didn't have much information, he doesn't know if his brash attempt would only make it worse for him. And as Chaos had predicted, Kisuke would need to first understand the situation or he won't be able to do much.
It became a race against who would reach their own goal first.
After a few minutes of observation and tracking the flow of energy, 'Null, huh? It's not really very helpful that Tiamat decided to hide her existence from me. It's as if she just left everything to fate and she's fine with disappearing too.' Kisuke clicked his tongue, 'Having a teammate that doesn't really care is a pain in the ass. I hope my last card works properly.'
Hearing that click of a tongue, Chaos thought that Kisuke was getting frustrated that he couldn't find an opening. But contrary to his belief, Kisuke had already found something but just hadn't found the right timing yet.
'Chaos is not 'eating' this Null, but absorbing a certain aspect of her. I don't really know how Chaos' ability works but I can assume it within the [Gluttony]-class of abilities.'
The [Gluttony]-class abilities. It's a group of abilities that has the concept of absorption. Some of Saji and Vali's abilities fall into this category, 'In Chaos' case, it seems to be the main concept. Or I could be wrong and he has something like [Assimilation]. In any case, I just have to find the right spot for the most effective disruption.
'Found it!' In his last attack, Kisuke finally found a converging spot at the wall furthest away from him and where most of the tentacles seem to emerge. But before he could attack it, he had to prepare for what's coming next, [Benihime, get ready to go all out. Once the timing is right, I'm releasing you along with my Shunkou.]
[Don't you dare use Hollowfication in that state if you want to stay alive. You might have immense regeneration in that form but the combined power output will destroy you from the inside. I'll handle your injuries.]
[If I were to insist, how many seconds could you handle keeping me in one piece?]
[Seven, give or take.]
[That's plenty.]
[But forget about fighting after that.]
[If I can't kill him after that, then I would have lost anyway.]
Kisuke was about to start when suddenly, Benihime asked him an unrelated question, [By the way... What is that dagger? I don't like it.]
[You'll know later... But I beg of you... Don't kill me.]
Benihime was shocked and confused by Kisuke's sudden plea. But before she could ask any further, Kisuke suddenly accelerated and focused on their current goal, "Shunkou!"
The bloody aura that manifested around Kisuke pushed the pursuing tentacles and without rest, he continued, "4th Gate: Depression!"
Chaos thought that Kisuke will attack him for real and prepared to crush him with overwhelming strength, but to his surprise, Kisuke went past him and reached the wall behind him, "Eat this shit, you fucking glutton."
He smashed his fist on the wall and injected a large amount of his aura into it. Immediately after, Chaos suddenly felt bloated and a stream of black blood suddenly emerged from his orifices, "...What?" However, before he could understand what was going on, the tentacle that was connected to Null inflated several times and his head exploded into a fine mist along with his numerous tentacles turning into dust.
