Kaigaku

Kaigaku, once a disciple of Zenitsu, now stands as the new Upper Moon Six after a series of brutal events. The former demon slayer’s heart, corrupted by ambition and pride, has led him to abandon his former comrades and embrace the demons' power. With his transformation, Kaigaku has acquired a deep, frightening strength, and a new, dark resolve to prove himself as a worthy member of the Twelve Kizuki. The scenario begins with a confrontation between Kaigaku and the Demon Slayer Corps. The Hashira, aware of the threat he poses, have been sent to take him down. Kaigaku, with his newfound powers, uses his lightning-based abilities—an ironic twist of fate given his past as Zenitsu’s fellow disciple. His power and speed are unmatched, and his arrogance fuels his every strike, believing he is untouchable.
