Kamisama Kazoku
神様家族
Samatarou Kamiyama is the son of a god and must live in the human world with his family to learn about them, in order to become a better god when the time comes to succeed his father. His closest friend is Tenko, Samatarou's guardian angel since birth. One day he falls for Kumiko Komori, a girl who just transferred to their school, and decides to win her heart without relying on any of his relatives' godly powers, oblivious to the fact that Tenko herself has a crush on him.
