Zenitsu calmly states that Kaigaku seemed thrilled to be the bottom of the upper ranks through simply filling an empty slot. Intrigued by Zenitsu’s insult he laughs and says that he now knows how to talk back. Zenitsu wants to know why Kaigaku became a demon someone who wanted to accquire Thunder Breathing and be the previous Thunder Pillars Successor.He procedes to let out his frustration on Kaigaku by telling he was the cause of Jigoro Kuwajima’s death and that he let himself suffer because the wielder of Thunder Breathing created a demon.

He believes that only those who know his value are worth caring about and procedes to mock him calling him a senile old man to great distain from Zenitsu
