In a quiet district of Tokyo, seven pupils evade school—sequestered in dim rooms, unable to confront relatives and peers—until the instant their bedroom mirrors begin to glow with an uncanny light.
A single touch transports them from isolation into a magnificent castle straight out of a Grimm legend. This fanciful realm, oddly devoid of nourishment and running water yet brimming with power outlets, shelters a sulky masked girl called Wolf Queen. She turns the castle into their playground and sanctuary during school days, offering games of riddles and hidden corridors. Concealed within its walls lies a key promising one wish, accompanied by cryptic clues that must be solved. Yet a stipulation looms: the key must be retrieved before the academic year ends, and they must depart by five each day or face a deadly fate.
With time, a grim revelation surfaces: only those bold enough to reveal their tales will survive. They begin unraveling each other"s narratives—one boy receives gadgets instead of affection; another endures a harsh, inexplicable rejection; a girl lives in terror of her predatory stepfather. As they obey the game's rules, an emotional saga unfolds: seven souls trapped in misunderstanding and solitude, each bearing hidden scars. Their shared stories grow louder, weaving empathy into the castle"s stone walls.
Ultimately, friendship, compassion, and sacrifice become the keys that unlock freedom. Together they confront their fears, break the curse of silence, and step out into the bright Tokyo streets, forever changed by the power of shared hearts.
