A man adopts his six-year-old aunt and raises her as his own kid.

At the funeral of elderly Souchiro Kawachi, his family is shocked to learn he had a six-year-old daughter named Rin. There is talk amongst the family of putting her up for adoption to avoid scandal and talk; disgusted at this behavior, Souchiro's grandson Daikichi decides to take her in himself and raise her as his own child. Thus he begins an arduous, consuming but ultimately satisfying trip through single parenthood, as he and Rin struggle to become a part of each other's lives and bond together.—Q. Leo Rahman

Usagi Drop centers on Daikichi, who takes a break from his busy life only to attend the funeral of his grandfather. Daikichi is 30: he is a very hardworking individual, who has never thought about the romantic side of his life. During the funeral he meets his relatives, who are discussing the fate of his grandfather's daughter and his aunt, Rin. Rin is only six and she is now literally alone in the world; there is no information on her mother, too. She is very shy and very quiet and, for some reason, her only relatives do not even care about her future: they simply find it too boresome to adopt the little angel, Rin. In the end, they decide to send her to an orphanage - Daikichi becomes enraged by indifference of his relatives and decides to adopt Rin. His life will change now.—Scientiiaa
