Lonely Castle in the Mirror

In a quiet Tokyo neighborhood, seven students avoid school-each hiding in their dim rooms, unable to face their families or friends-until the mirrors in their bedrooms suddenly begin to glow. With a single touch, they're whisked away from their isolation into a fantastical castle straight from a fairy tale. This strange place, oddly devoid of food and running water but filled with power outlets, becomes their daytime escape, ruled by a masked girl called Wolf Queen. Hidden somewhere in the castle is a key that grants one wish, along with clues to find it. But there are rules: they must find the key before the school year ends, and they must leave by five each day-or face deadly consequences. As time runs out, a harsh truth comes to light-only those willing to share their deepest struggles will survive. One by one, they reveal their hidden pain: a boy drowning in material gifts but starved for affection, another crushed by unexplained rejection, a girl terrified of her predatory stepfather. Bound by the game's rules, their stories unfold-a tale of seven lost souls trapped in loneliness and misunderstanding, who find freedom through friendship, empathy, and sacrifice.
