Maiya Hisau

Serving as a stoic and efficient assistant to Kiritsugu Emiya throughout the fourth Holy Grail War, this disciplined professional provides the cold detachment necessary for his grim operations. Though her past remains largely mysterious, she was once a child soldier rescued from a violent conflict by Kiritsugu, who subsequently became her mentor. Beneath her hardened exterior lies a tragic history of wartime trauma and loss, which she eventually confides to Irisviel von Einzbern.
