Genre: Comedy, School

Based on the manga of the same title, the story revolves around three sisters, Haruka, Natsu, and Chiaki. As they don't have parents, the eldest sister, Haruka, does most of the housekeeping chores although she goes to high school. The second sister, Kana, is a junior high school student. She is a cheerful girl but a bit of an airhead. Chiaki still attends elementary school, but she is a cool and ironic person, and often makes a fool of Kana. Most of the stories are scenes of their daily lives, and they progress normally without remarkable climaxes.
