Zenitsu Agatsuma

Zenitsu Agatsuma is defined by his "Thunder Breathing" style. Though he lacks confidence and constantly fears for his life, his true power emerges when he loses consciousness. In this state, his instincts take over, allowing him to execute lightning-fast strikes with incredible precision. His character arc is a compelling journey of overcoming self-doubt to protect his friends. Whether he is screaming in terror or mastering the First Form, he remains one of the most memorable characters in anime.
