Ryuujin no Rinjin

A female college student, Toko Himesaki, suddenly finds herself living next door to a new neighbor—Hon, an exchange student who also happens to be a dragon person. Despite her divine appearance, Hon is clumsy and absent-minded, and Toko just can't bring herself to ignore her. Thus begins a laid-back fantasy comedy about cross-cultural exchange, set in a student dorm!
