Hanadera Himawari is a first-year high school student. Both of her parents passed away six years ago, but as the Hanadera family's eldest daughter, she is busy running around every day. She lives together with her four kind, but too-free siblings named Sakura, Kikunosuke, Aoi, and Umeta. They might be poor, but their life together is fun! It's a warm, busy family comedy of the Hanadera family.
