Upon arriving at the house, he meets a mysterious young girl named Rin who, to Daikichi’s astonishment, is his grandfather's illegitimate daughter! The shy and unapproachable girl is deemed an embarrassment to the family, and finds herself ostracized by her father's relatives, all of them refusing to take care of her in the wake of his death. Daikichi, angered by their coldness towards Rin, announces that he will take her in—despite the fact that he is a young, single man with no prior childcare experience. Usagi Drop is the story of Daikichi's journey through fatherhood as he raises Rin with his gentle and affectionate nature, as well as an exploration of the warmth and interdependence that are at the heart of a happy, close-knit family.

As time marches on, he must confront an impossible question: at what cost does he chase his beautiful dream?
