Haruto wakes up in a dream he can't leave, and every witch he meets has built her own world out of trauma. The show doesn't explain itself, it lets the logic of dreams take over, where the rules shift and the real threat isn't monsters but the person next to you refusing to wake up. By the time you reach the end, you realize the show never cared about solving anything; it cared about what you believe about the person dreaming.

Haruto Tsukishiro opens his eyes in a world that shouldn't exist. After falling asleep as usual, he finds himself stuck inside a dream world. There he encounters a mysterious girl named Lily, then meets Kanzaki and learns that witches exist. These witches haunt the dreamscape, and they are more than figments: they are the trapped souls of young women who turned away from reality and suffer from Sleeping Beauty Syndrome. Now caught up in one incident after another, Haruto searches for a way back out while facing the witches and their frightening powers. The series blends adventure, fantasy and mystery with a supernatural edge, and forms part of a larger multimedia project that also includes a mobile game and a virtual reality game.
