Zenko

Zenko is just as strong-willed and headstrong as her brother, but dislikes violence. She is caring and very protective of her brother. In addition, she is quite fearless as she was willing to go into an evacuated city during a monster crisis and was unafraid to stand up to Garou. Like her brother, she's very hot-headed, to the point of even arguing with Garou despite risking both her life and her brother's. (Source: One Punch Man Wiki)
