Rei Aragaki

Rei is the daughter of Joutarou. She is a fourth grade student. Rei loves ninjas.

Rei is a kind and conscientious young girl. She does everything she possibly can to support her father, including cooking and cleaning up around the house. Rei is frequently teased in school due to her famous father, but tries her best to make sure that Jotarou never hears about this bullying. Rei doesn’t want to be seen as a burden to her father, and often blames herself for things that aren’t her fault.
