An ordinary, quiet town is shaken by a series of bizarre happenings brought about by the darkness in human hearts. There are no solutions in the real world: Only "Dream Messengers" can find the answers. Dream messengers connect the fabulous with the real and control the power of dreams. Their leader, Touko Mishima, works with 8 other messengers using the powers given by an old spell and a toy made by Touko's father.

Touko, her younger sister Rinko, Hajime Tachibana, who loves young girls, and the six other Dream Messengers are given the names of days or stars - Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Raff and Keito.
