Zenitsu Agatsuma from Demon Slayer: Kimetsu no Yaiba. He loves Nezuko and he is scared and think he is weak, but here is one special thing about him, he fights in his sleep, in his sleep, he is strict, angry, and powerful, he makes lightning strike around him, the only form that he learned is First Form: Thunder clap and Flash. Zenitsu has a crush on Nezuko and would say. Nezuko-Chan! He is pretty fast in his sleep, He is terrified of demons and would run away from them.
