Book #40 of 2025:
Lonely Castle in the Mirror by Mizuki Tsujimura
This is an odd little story. It’s a translated version of a Japanese bestseller, and I’m sure there are some cultural nuances that I’m missing, as I’ve had a particularly hard time swallowing the basic premise here. Not the mirror that magically transports the tween protagonist to a mysterious castle; that’s a perfectly fine fantasy element as far as I’m concerned. But she and the other young kids she meets there are just indefinitely staying home from school, for various personal reasons? No parent or government authority compels them to attend? Apparently this is a genuine phenomenon in Japan known as futoko, but it’s so far removed from my expectations and understanding of educational pedagogy that I think I’ve struggled with how to approach this novel as a result.
For our heroine, the inciting cause of her seclusion was a severe case of bullying and bodily threats that’s led her to quit being a student and stay home all day while her parents continue to go into work. Once through the looking glass, she encounters six fellow dropouts, who gradually share their own sad backstories as they come to bond Breakfast Club-style. They’re additionally greeted by a strange girl in a mask, who tells them that they can come and go via their mirrors during normal school hours until the term ends in March. If they ever linger past curfew, a wolf will eat them. If they can find a secret key that’s hidden somewhere in the building, one of them will be granted their heart’s desire at the cost of the whole group losing their memories of the castle. If no one finds the prize or uses it to make a wish, the portals will still close for them in April, but at least they’ll get to remember it all.
Those rules are a bit too weird for me as well, and although the overall experience is eventually explained (in what’s easily the book’s most moving sequence at the end), the arbitrary logic still chafes. There’s also a connection between the children — who don’t know each other in their real lives — that seems so obvious that I wish it had been moved up earlier in the text, as I’ve spent too long impatiently waiting for the characters to realize it for themselves.
I do like certain parts of the plot, and I’ll readily grant that I’m outside of the original intended audience, but in my opinion not enough of the project coheres together for me to wholly embrace it.
