Aunt to the sisters from their father's side, Misako is the 29-year-old virgin that unseals the Dream Cyclone weapon for the Yume Tsukai. She spends time at the family house where the Dream Cyclone shrine resides, waiting for the call to arms when the team is out on a job. Misako is very up-to-date with technology, but limits herself to her cellphone and computer. Being very sensitive about her age, she makes a point to let everyone know she's 29, and not 30.

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.

When people dream, they express their utmost desires and emotions within the confines of their mind; but when their strong emotions cross the border into reality, the dream can turn into an uncontrollable nightmare. 
Touko and Rinko are sisters known as "yume tsukai" (dream users), and their job is to take care of these nightmares. Using toys as weapons, the girls must both destroy the nightmare and return the dream to its rightful owner before the nightmare does any sort of serious damage. 
Have no fear, Touko and Rinko are here!
