People's dreams often reveal their deepest desires and emotions in a private mental space. However, when intense feelings spill over into reality, it can lead to an uncontrollable nightmare. Two sisters named Touko and Rinko have been trained as "yume tsukai" (dream users) to handle such situations. They use toys as weapons to defeat the nightmares and restore the dream back to its original owner before any harm is done. Don't worry, Touko and Rinko are on hand to help!
