Kaigaku

Kaigaku. Zenitsu's fellow disciple under Jigoro Kuwajima, and the Thunder Breathing swordsman who turned demon. He serves Muzan as Upper Moon Six and stands against Zenitsu in the end. Proud, bitter, and sure he is owed more than he got. Edited far more than his fan-favourite standing suggests. 54.6M views across 2,473 tracked edits. Dark, sharp, black and gold.
