Lonely Castle in the Mirror The Movie

Kokoro Anzai, a first-year at Yukishina Junior High School, is avoiding going to school due to bullying. She becomes uncomfortable while attending a child development support class, and has not returned to school since. One day, she finds the magical portal within the mirror at her room. While inspecting, she is dragged into the mirror and finds herself in front of a castle on an island surrounded by water. There, she is welcomed by a girl with a wolf mask. The self-proclaimed Wolf Queen introduces her to six others: Subaru Nagahisa, Akiko Inoue, Rion Mizumori, Earth Masamune, Fūka Hasegawa and Haruka Ureshino. Addressing them as Little Red Riding Hoods, the Wolf Queen instructs them to find a key hidden in the castle, which will lead them to a room where one can make a wish, before the deadline of March 30 of the following year. If anyone makes a correct wish, it will be granted and all children will lose their memories of the castle. She also tells the children to leave before 5pm. Any child who stays at the castle on the evening will be eaten by a wolf. The seven children start spending time together at the castle, occasionally looking for the key. A year has passed, but they have not succeeded. Kokoro learns from the children that they attend the same school, except for Rion and have been avoiding school for various reasons.

The deadline is nearing, but they have not found the key yet. In the meantime, Kokoro has opened up to her mother about being bullied and with the help of her teachers tries to resolve the issue. The others have also taken steps forward. On the second to last day, Kokoro finds an illustration titled "The Wolf and the Seven Young Goats", and realizes that this was a clue to the key's location. As she returns home, she discovers the mirror shattere
