Ooka is Fij Fij's best friend, but she's not as neat as Fij Fij. In fact, Ooka is very messy. Ooka is peppy and bouncy, and she doesn't always think before she acts. That can get her into trouble. Luckily, Maryoku is there when she needs her. Ooka loves to play -- a lot more than she likes to do chores. But she's learning and growing, and that's what Nozomu is all about.
