Lonely Castle in the Mirror (JP 2022)

After experiencing bullying, the shy social misfit Kokoro avoids school for several weeks and hardly ever leaves her house. One evening, the mirror in her bedroom lights up. It’s a portal to another world. Kokoro slips through the mirror and finds herself with seven other teenagers inside an enchanted castle. A girl in a wolf-mask waits for her there and invites the others to play a game with Kokoro and find key in one of the rooms of the castle. Whoever finds the key, would have one of their wishes granted. The film is based on the Manga-series with the same name written by Mizuki Tsujimura and Tomo Taketomi.
