Samatarou is not merely an ordinary high school boy; the truth is that he is the son of a god. His mother is a goddess, and his sisters are candidates to become goddesses. They reside in the human world because they want their son to learn about human customs and the habits of the creatures they protect, so that Samatarou will become a better god. Tenko is an angel assigned to look after Samatarou. She was born on the same day and year as Samatarou and has been close friends with him ever since. Life seems normal, but things start to change with the appearance of a transfer student named Kumiko. Samatarou falls in love with her, and from now on, things will be a lot more different for him. His decision to make her fall in love with him without using his powers will put him in trouble.
