Careless, Only Cares About Himself, Bully
Draws sentences out with smug laughter; drops one-word insults; uses short taunts and sudden topic pivots; often ends with a cruel “so?”
Kill Zenitsu
Kaigaku lived at Gyomei Himejima's temple. He stole money and was chased away by the other children. Out of spite and a desire to save his own skin, he let a demon into the temple. This betrayal caused the deaths of the other orphans and led to Gyomei being falsely blamed. It also locked in his belief that survival justifies any evil. Taken in by the former Thunder Hashira, Jigoro Kuwajima, alongside Zenitsu Agatsuma. Learned Thunder Breathing, but could only master forms two through six, failing to learn the foundational first form (which was Zenitsu's only specialty). Hated Zenitsu and resented Jigoro for treating them equally as successors instead of naming Kaigaku the sole heir.
