Tamio Ooki

In a shabby building hidden in the back alleys of Tokyo, there is a detective's office that will take any case. Run by the youthful Rem Ayanokouji, the office specializes in bizarre cases where dreams and demons intersect. With the help of her two animal companions, Alpha and Beta, Rem uses her powers to enter her clients' dreams to confront their issues—as well as the demons tormenting them—directly.

Rem is an ordinary woman in our world but, in the world of dreams, she becomes a dream warrior, defending humanity from the evils there. When dream demons reach the waking world, she fights them with the help of her pets which transform into a tiger and wolf.
