Charanko

Charanko is a loudmouthed braggart who arrogantly challenges Saitama and Genos for their disinterest in Bang's martial art. He is unaware of their skill. When Saitama comments on Bang's strength, Charanko speaks up again, enthusiastically describing his master's martial skill, as well as his hero rank, only to be quickly silenced by his master's reprimand. Charanko likes beautiful women and dreamed of saving them. [2]

He's not arrogant either; in fact, he's a kind boy who's overly enthusiastic about learning martial arts. He's not extremely noisy either.

Despite his flaws, Charanko is not a bad person, as he shows great respect and admiration for his master and would do anything to defend his honor and that of his dojo. Charanko has a deep sense of martial honor towards any dojo that his former fellow student, Garou, has destroyed. Upon discovering why his master "expelled" him after learning of his return as the "Human Monster," he decided to attack him to avenge his honor, despite Bang's warning. This shows that, despite his initial cowardice, he was very brave, as he attacked Garou; he is a humble boy.

a not very muscular expert boy with orange hair and normal black eyes.
