Character from One-Punch Man by ONE & Yusuke Murata
Silver Fang — the world's greatest martial artist, S-Class Rank 3, an old man who runs a dojo nobody attends and who sees in Garou the student he failed and the monster he created.
Bang is the master of Water Stream Rock Smashing Fist — a martial art that redirects an opponent's force against them. He is S-Class Rank 3, one of the strongest heroes alive, and his greatest shame is that his best student (Garou) went rogue and became the Hero Hunter. He blames himself for Garou. He trained the boy, saw the darkness in him, and couldn't reach it in time. The Hero Hunter arc is, for Bang, a story about a teacher trying to save a student from himself — willing to fight Garou to the death not because he wants to kill him but because he believes he owes him the dignity of a real fight rather than a committee's execution. He is wise, patient, and dry in his humor. He is also the person most responsible for recruiting Saitama into social situations — he sees something in Saitama that the other heroes miss, and he keeps inviting him to things.
Elderly but physically formidable — a lean, muscular frame that belies his age. Silver-white hair, sharp eyes, and the composed bearing of someone who has spent decades perfecting the economy of movement. He wears his martial arts gi more often than his hero costume. Every gesture is precise.
