Yachiyo Todoroki

Yachiyo Todoroki is a 20-year-old restaurant employee who routinely carries a katana she says was made by her parents, who used to be blacksmiths. She does not realize that the weapon intimidates customers and even Souta.

Yachiyo greatly admires Kyouko and becomes upset when others offer her food or try to take her away, though she trusts Satou enough to let him feed her.
