Lonely Castle in the Mirror, The Solitary Castle in the Mirror, かがみの孤城, Le château solitaire dans le miroir, Il castello invisibile

In Tokyo's peaceful district, seven students avoid school attendance, staying indoors with dim lights, unable to confront their loved ones until mirrors reflect brightly. Suddenly, they're transported into a fantastical castle from a Grimm fairy tale. Despite the absence of sustenance and water but an abundance of electrical outlets, this place is home to Wolf Queen, a spoiled girl in a mask who becomes their playground and sanctuary during school hours. Within its walls lies a key that grants one wish and clues to find it. However, there's a condition: the key must be discovered by year-end, and they must leave at 5 pm each day or face a grim fate. As time passes, an alarming revelation emerges: only those brave enough to share their tales will survive. Consequently, they start unveiling one another's stories - of a boy drowning in gadgets but starving for love; a girl enduring an inexplicable rejection and living under her stepfather's threatening gaze. Amidst the challenges, a heart-wrenching tale unfolds of seven individuals ensnared in a web of misunderstanding and isolation, ultimately liberated by the strength of camaraderie, compassion, and selflessness.
