Ginrou is Kinrou's younger brother and one of the village guards. He is shorter and scrawnier than his brother, with short blonde hair and green eyes. He usually wears a karate gi-like uniform and belt and carries his spear wherever he goes. He and his brother were two of the first villagers to join the Kingdom of Science.

Spoiler

During the adventure on Treasure Island, Ginrou manages to convince Matsukaze to serve him due to the resemblance Ginrou bears to his late master.
