Sister Princess

As Wataru gets used to life in the mansion, many mysteries await him; there's a blistering-hot kimchi gratin no one remembers cooking; he encounters a monster out in the woods; also he meets even more sisters of his.

Wataru and his sisters attend their first day of school, but Wataru feels the pressure to watch over them; everywhere he goes at least one of his sisters follows him wanting attention, and Wataru starts to feel overloaded.

Hinako, the youngest of the sisters, is missing; she has left a note that she's going to look for Mr. Teddy Bear; Kaho asks Wataru to go look for her, and it ends up being quite an adventure for them both.

Wataru, Mami and the sisters write a play about twelve princesses to try and win a contest.
