GKIDS Films has announced that the anime film adaption of Lonely Castle in the Mirror will premiere in North American theaters later this year, showing Mizuki Tsujimura’s story of a lonely girl who finds herself in a magical world just beyond her bedroom mirror.

“Shy outcast Kokoro has been avoiding school for weeks when she discovers a portal in her bedroom mirror. She reaches through and finds herself transported to an enchanting castle where she is joined by six other students. When a girl in a wolf mask explains that they have been invited to play a game, the teens must work together to uncover the mysterious connection that unites them. However, anyone who breaks the rules will be eaten by a wolf.

From acclaimed director Keiichi Hara (Colorful, Miss Hokusai) and based on the bestselling novel by Mizuki Tsujimura, Lonely Castle in the Mirror is a heartfelt drama about the pains of growing up and the unlikely bonds that can bring people together.”
