Usagi Drop

Upon finding out that his grandfather has passed away, Daikichi Kawachi returns to his family home where he unexpectedly meets a young girl named Rin – who's allegedly his grandfather's illegitimate daughter. When none of Daikichi's other relatives offer to take her in and suggest she be put up for adoption, he decides to adopt her himself. However, Daikichi has no experience with children, and finds that he has to completely rearrange his life in order to care for Rin, but is willing to do whatever he needs. Can this 30-year-old man learn how to become a father? This anime was based on the manga of the same name by Yumi Unita.
