Amagami-san Chi no Enmusubi

After losing his mother, Uryuu Kamihate loses faith in the gods and puts his trust in science instead, fixing his sights on a single goal: entering Kyoto University's medical school. Looking for somewhere quiet to study, he moves into Amagami Shrine and finds himself living with three shrine-maiden sisters, Yae, Yuna, and Asahi.

Their grandfather soon reveals the condition Uryuu never expected: if he is to stay, he must eventually marry one of the sisters and inherit the shrine. For a boy who rejects faith altogether, the idea seems impossible, especially with the sisters' clashing personalities and beliefs. Yet life under one roof, and the problems they begin solving together, slowly tie Uryuu's future to a family he intended to treat as only a temporary stop.
