Kami-sama Kazoku

Samatarou may seem like an ordinary high school boy, but in reality, he's the son of a god. His mother is a goddess, and his sisters are training to become goddesses themselves. They live in the human world so Samatarou can learn about human customs and the lives of the beings they protect, preparing him to become a better god. Tenko, an angel assigned to watch over him, has been his close friend since birth-they share the same birthday and year. Life is peaceful until Kumiko, a transfer student, arrives. Samatarou falls for her, and everything changes. Determined to win her heart without relying on his divine powers, he soon finds himself in over his head.
