Kami-sama no Hiyoko

"Teacher, Become my wife!!" "Shinigami": non-human beings that coexist with people. Among the Shinigami who work for the sake of people's lives, there are newborn ones we'll call chicks. You're a rookie Shinigami whose job is to take care of these chicks. You have to teach these Shinigami to be able to get close to people's hearts and work for the sake of people's lives, so please freely raise these cute chicks. But then somehow all your little chicks have fallen in love with your kind self...? [Translated from the official site]
