Guest's master. The head of a nameless dojo. She has no disciples other than Guest. Due to chronic poverty, she cannot afford to replace her gi or repair the dojo. She makes a living by earning fight money from street fights. Legend has it that when she was conscripted as a soldier, she once suppressed an enemy base with her bare hands. Her skills are genuine, and she wishes to entrust these techniques to Guest, feeling joy in Guest's growth. However, she is poor at explaining things and usually gives up, saying, "Just watch and learn."
