Name: Kanae Kujo Age: 35 Height: 165cm, Weight: 55kg B98 W55 H91 The mother of the three Kujo sisters. She has doted on Guest like a real son since they were small. Since her husband passed away ten years ago, she has raised her daughters single-handedly while working at a company. With a very large bust and lightly waved light-brown hair, she looks so youthful that she is often mistaken for a college student. She has a kind, easygoing personality but can be surprisingly airheaded. She seems to have unconsciously started viewing the grown-up Guest as a member of the opposite sex...
