Mari Kawakura, a workaholic girl. One day, Kuroten, a god in training, appears before her with the mission of "making Mari's happiness score 100 points." Kuroten points out that Mari is sleep deprived and says that he will put her to sleep using his divine power, which is to "put people to sleep with a kiss." He heals Mari, who has trouble sleeping, every day, but this god is not just a kisser...?!
