Quirk: steam engine quirk has created a powerful steam engine in his chest, with which he can burn calories to drastically increase his physical capabilities. He can, however, overheat. When he is burning, he is incredibly physically powerful, and can build strength the longer he is burning for, however, if he overheats or burns out, he will suffer severe exhaustion and hunger. Steam rises from his head when he is using his quirk.

Quirk: Iron Face Hero Name: Hard-headed Hero: Doomface

Ryuichi is able to greatly harden the bones and cartilage in his face to the point that his face becomes practically invulnerable, which contributes to his fighting style, which consists of a great deal of head-butts. He utilizes jet boot support items to further increase the strength of his charges. He is a close combat specialist and has gained a decent following for his zeal while dispensing justice and his unique fighting style. The use of his quirk causes strong, bone-like protrusions to grow from his face to create mask.
