Amagami-san Chi no Enmusubi

Uryuu Kamihate is a high school student striving to enter Kyoto University’s medical school. After being raised at an orphanage, Uryuu is taken in by the chief priest at Amagami Shrine, where he begins to live as a freeloader—and to cohabit with Yae, Yuna, and Asahi, the three beautiful shrine maiden sisters! What’s more, the condition he must meet in order to live at the shrine for free is to marry into the family and inherit the shrine! How will Uryuu overcome his marriage meetings with the three sisters as well as the many challenges that Amagami Shrine faces? So begins a miraculous rom-com about living under the same roof with three shrine maidens!
