In a tranquil neighborhood of Tokyo, seven students are avoiding going to school—hiding in their darkened bedrooms, unable to face their family and friends—until the moment they find the mirrors in their bedrooms are shining.

At a single touch, they are pulled from their lonely lives into a wondrous castle straight out of a Grimm's fairy tale. This whimsical place, oddly lacking in food and running water but full of electrical sockets, is home to a petulant girl in a mask, named Wolf Queen and becomes their playground and refuge during school hours. Hidden within the walls, they're told there's a key that will grant one wish, as well as a set of clues to find it. But there's a catch: the key must be found by the end of the school year and they must leave the premises by five o'clock each day or else suffer a fatal end.

As time passes, a devastating truth emerges: only those brave enough to share their stories will be saved. And so they begin to unlock each other's stories: how a boy is showered with more gadgets than love; how another suffers a painful and unexplained rejection, and how a girl lives in fear of her predatory stepfather. As they struggle to abide by the rules of the game, a moving story unfolds, of seven characters trapped in a cycle of misunderstanding and loneliness, who are ultimately set free by the power of friendship, empathy, and sacrifice.

My first impression. The foreshadowing is wonderful. Reminds me of my childhood. A slightly dark story continues, but at the end you can see the path of light.

- Great foreshadowing
As written in the story synopsis, this is the story of seven junior high school students who are unable to go to school due to various problems, and the castle's master, who wears a wolf mask.
The original novel was released in 2017. In 2018, the bookstore grand prize (given to the book that bookstores want to sell the most). Many people admire this story.

I saw the movie without reading the original novel. Until the middle of ...

Mixed Feelings
TLDR: After watching the movie I honestly felt like it was a waste of time. Was it a good movie? It was fine. Is it worth watching? Only if you have time, there are a lot of anime/movies to watch rather than watching this one. If you have not watched Wonder Egg Priority then watch that instead, both have quite a similar story and setting and in my opinion the latter did it better. Watch this movie only if you have spare time(which means you dont have any anime back log, go clear your back log first... I am pretty sure that decade old anime ...

I was really disappointed with this adaptation from manga/book to anime. So many details were missing, even important ones. It's a shame because the book is really good. Watching it, you don't even get to know the main character properly. Of course, she doesn't talk much, but she has a lot of inner monologues that build up her character. The other characters have as much personality, which is a shame. Everything is so random, and the pacing is even worse because the movie is so rushed. Let's not talk about the animation.
I wouldn't recommend this movie, and I'd rather suggest reading the book. I ...
