Kamigami no Asobi

Yui Kusanagi, a third-year high school girl, is abruptly transferred to a strange realm after finding a mysterious sword in her home's stockpile. Before encountering Zeus, the king of the gods, Helen meets five weird yet attractive men while exploring her new surroundings. Zeus founded the Academy of the gods and appointed Yui as its sole professor in an effort to repair the worsening relationship between the gods and humans. She has a year to teach the young and hesitant gods, including the five strangers she met earlier, what it means to be a human while also learning about the gods; else, they would all be confined to Zeus' realm for all eternity.
