📖 SYNOPSIS
Seven kids too afraid to face school discover their bedroom mirrors beginning to glow, and everything changes. When they touch the glass, they're pulled into a fairy tale castle ruled by a girl in a wolf mask who tells them there's a hidden key somewhere inside — and whoever finds it gets one wish. The catch: they have to leave by five o'clock every day, or something bad happens. That's the setup for this special companion piece to the Lonely Castle in the Mirror film, animated by A-1 Pictures and based on the novel by Mizuki Tsujimura. At the center is Kokoro, a junior high girl staying home because of bullying, and Rion, a soccer player at a boarding school in Hawaii. They're strangers with nothing obvious in common, but the castle slowly draws out the reasons each of them ended up there. The tone sits in this quiet, aching space between fantasy and real-world pain — loneliness, isolation, the specific helplessness of being a kid who feels invisible. It never rushes. The mystery of the castle unfolds alongside the mystery of who these seven people really are to each other. If you liked the emotional gut-punches of Anohana or the way Erased wove time and childhood trauma together, this hits similar notes. It also shares DNA with The Girl Who Leapt Through Time in how it uses a fantastical premise to get at something deeply human. Worth your time if you want something that lingers.
