De verlegen outcast Kokoro vermijdt al weken school als ze een portaal in haar slaapkamerspiegel ontdekt. Ze reikt er doorheen en wordt getransporteerd naar een betoverend kasteel waar ze wordt vergezeld door zes andere studenten. Wanneer een meisje met een wolvenmasker uitlegt dat ze zijn uitgenodigd om een spel te spelen, moeten de tieners samenwerken om de mysterieuze connectie te ontdekken die hen verenigt. Iedereen die de regels overtreedt, wordt echter opgegeten door een wolf.
Nee, helaas is かがみの孤城 nog niet beschikbaar op Netflix in Nederland.
