Mitsu Momoi

Saku Momoi's (Loli) grandmother. She has a kind personality and is very caring about Saku; she is also Saku's current guardian. Saku also cares a lot about her grandmother as she stayed behind in Japan when her parents were moving overseas because of concern of her grandmother living alone. Saku takes her appearance and petite structure from her as is shown in a picture of Mitsu from when she was 15 years of age in the manga (Ch-54).
