Kami-sama Gakkou no Ochikobore

Modern Japan, a very ordinary world. But it's a little different. Gods exists in this world. One day, Nagi, who is about to enter high school, suddenly receives a letter of acceptance from the "Gods' School" where people with supernatural powers gather. Even though she hasn't even taken the entrance exam? They say she passed the recommendation frame from a strange god, but Nagi's grades are the lowest in his grade among only elites enrolling! The daily life of a school dropout girl begins to move towards the extremely difficult national qualification "God"!
