Hatsukoi Sacrament

Yuuhi is entering Millenia Academy this spring. Since he wanted to live by himself, he found himself an apartment room. However, when he stepped into the church next door, he found a girl lying there. Her name was Hikari and and she doesn’t remember much except that her goal is to help people. She ends up living with him at the recommendation of the apartment manager, Noa. He thinks that if they go about helping people, Hikari may regain her memories. So, together they start up the "Big Sky" club to solve students’ problems.
