The Lonely Castle in the Mirror anime movie’s main heroine Kokoro will be voiced by newcomer Ami Tou, a 15-year-old actor who made her acting debut with a commercial in 2021. It was also revealed that the movie will premiere in Japan on December 23.

A new 30-second trailer and a poster for the film were released as well. Additionally, more staff members were revealed in the form of Miho Maruo (Birthday Wonderland) as scriptwriter, Keigo Sasaki (The Millionaire Detective Balance: Unlimited) as character designer and chief animation director, Ilya Kuvshinov (Ghost in the Shell: SAC_2045 character designer) as visual concept artist and lonely castle designer, and Harumi Fuuki (The Deer King) as music composer.

It was previously announced that Keiichi Hara (Birthday WonderlandMiss Hokusai) was directing with A-1 Pictures as the animation production company.

Lonely Castle in the Mirror is based on the 2017 Poplar-published novel (titled Kakami no Kojou/The Solitary Castle in the Mirror in the original non-translated version) by Mizuki Tsujimura. The novel was later translated into English by Philip Gabriel and released with the Lonely Castle in the Mirror title in 2021. 


Penguin Random House describes the book as:

How can you save your friend’s life if she doesn’t want to be rescued?

In a tranquil neighbourhood of Tokyo, seven teenagers wake to find their bedroom mirrors are shining.

At a single touch, they are pulled from their lonely lives into to a wondrous castle filled with winding stairways, watchful portraits and twinkling chandeliers. In this new sanctuary, they are confronted with a set of clues leading to a hidden room where one of them will be granted a wish. But there’s a catch: if they don’t leave by five o’clock, they will die.

As time passes, a devastating truth emerges: only those who dare to share their stories will be punished.

Tender, playful, gripping, LONELY CASTLE IN THE MIRROR is a mesmerizing tale about the importance of reaching out, confronting anxiety and embracing human connection.

The novel was the winner of the Japan Booksellers’ Award as well as a No. 1 bestseller in Japan. It was also one of The Guardian’s 2021 highlight titles. A Shueisha-published manga adaptation by Tomo Taketomi began in 2019.
