Nakahara Yusuke is a high school boy who has a very loving younger sister, Maria. She loves spending each day taking care of him, doing things such as cooking and cleaning around the house. However, she typically goes a bit too far into treating him like a child--she has a habit of coming to his classroom at lunch to hand-feed him his bento, or brushing his teeth for him at home. She even snoops out his hidden porn magazines. Other people think they're a bit weird, and that Maria acts like his lover or his mom.
Mutsumi, the oldest sister, is an excellent cook and has a loud voice. The second oldest, Akemi, is a beauty who likes to read books. The third, Izumi, is a cheerful and straightfoward sporty girl. Hitomi, the youngest sister, is a tidy and graceful girl who is good at knitting.

When Karin finally makes an important decision regarding her future, tragedy strikes their family that will change the course of their lives.
Meet the Minami sisters, three girls living on their own and doing their best to make it through life's little snags and adventures.

Together, no obstacle can stand in their way, be it school, romance, or even cooking.
