There are three of the Minami sisters: Haruka, Kana and Chiaki, who have an average life. The girls only have each other to depend on and help each other get through everything from love confessions to cooking.
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.
Kana doesn’t like to get up in the morning and so is usually late and misses breakfast. When Kana stays home she sleeps all day instead of making dinner, and then rushes together a dinner-from-hell. Haruka doesn’t know how to explain kissing to Chiaki, so Kana decides to “teach” Chiaki.
When a boy gives a love letter to Kana, Chiaki convinces Kana that it is actually a challenge to a fight, so Kana kicks the boy in the leg when he is getting ready to “confess” to her. The basic premise of the jokes in the first episode is that all three girls are totally naive, even Haruka.
Main Characters

Kana Minami is the middle sister in her second year of junior-high school. Kana is a lively girl who never thinks before acting. She often acts or talks impolitely without thinking, much to the annoyance of Chiaki.
Chiaki Minami is the youngest sister in elementary school. She is in class 5-2 (a reference to Kyo no Gononi). Her apparent high intelligence often makes her overanalyse simple stuff. She also tends to ignore idiotic behaviour displayed by Kana and Makoto.
Takeru is first cousin of the three sisters. He occasionally visits the Minami sisters to check up on them and give them their monthly allowance. He often makes blunders and Kana, with exception from Haruka and Chiaki, feels he’s “pathetic”.
Hosaka is a third year, and captain of the volleyball club. He would like for Haruka to become the volleyball club’s manager. He has tendancy to act cool and the habit of fantasizing in front of people, making those who knows him label him as weirdo, especially Maki.
