Synopsis
Teenager Haruto Tsukishiro wakes up in a strange bedroom within a dream world and discovers an unusual app on his phone. Upon activating the program, a strange woman manifests and attempts to pull him into her realm, but a mysterious white-haired girl interrupts their connection, saving Haruto and identifying the antagonist as a witch before their interaction is abruptly terminated. When Haruto re-enters the dream realm, he encounters Katsumi Kanzaki, an anthropomorphic talking cat, while the white-haired girl opens a portal for them to escape the witch’s minions. Following the incident, Katsumi, an expert on dream world research, identifies the only-visible-to-Haruto girl as "Lily," a figure who recurs across various dreamscapes. Aiming to exit via a blue door, Haruto and Katsumi return to the witch’s domain, where Lily explains that witches are trapped in a coma-like state known as "Sleeping Beauty Syndrome" due to real-world torment, requiring defeat in the dreamscape to awaken. After defeating the witch and finding the blue door, Haruto and Katsumi part ways with promises to meet in reality. However, Haruto finds himself back in the dream bedroom upon exiting. Determined to find answers, Haruto and Katsumi begin investigating the secrets surrounding the witches, Lily, and Haruto’s own inability to leave the dream world.
