In Yomegami the world is at peace, but mankind is unaware of the miracles in this world, as well as the struggle going on in the world of Gods. We pick up the story in spring in a provincial town called “New Masado City”, when a transfer student named Hayato transfers in at an unusual time. Hayato is the reincarnation of a devil that went on a rampage in the past. His mother, iris, is also a reincarnation of a former power. But in her case it’s a goddess rather than a devil. She told him that if he performs enough good deeds in the human world, he would be able to return to the world of Gods. And so Hayato attempts to live his life as a youth in accordance with her words. Unfortunately, the devil’s power still hold power over him and it happens that he snatches a kiss from his new classmate Mikoto. If this misunderstanding continues, all of his previously accomplished good deeds will be nullified! He takes on the help of his best friend and class president Mari to find the right way and time to apologize. But then a mysterious and mischievous dog-eared girl appears and events take a turn for the worst. Why did this have to happen to him!? It seems his life is too deeply connected with his previous existence…
