Hisau, Maiya

久宇舞弥

A young woman serving as Kiritsugu Emiya's assistant during the fourth Holy Grail War. Her cold and professional demeanor facilitates Kiritsugu's necessary actions.
Her past remains largely unknown, except that Kiritsugu rescued her from a war-torn region many years prior. As a child, Maiya was conscripted into the army and trained as a soldier. She later discloses to Irisviel von Einzbern, Kiritsugu's wife, that she was raped by fellow soldiers and subsequently lost her child. Following her rescue, Kiritsugu became Maiya's mentor, instructing her in his way of life.
