Imagine that your personality is a shadow that tries to control your appearance, which is separate from your personality.
From the same studio CloverWorks, this anime gave me The Promised Neverland vibe. It took place in a confined place, had many children being under guidance of adults, and had a bigger force at hand. However, the premise of Shadows House is still unique, and an interesting one.
The animation was solid as usual from CloverWorks. Our main girl was especially cute, as well as other characters. They all had great eyes and smiles, but not creepy like Promised Neverland.
The story was a fun thriller with mystery in between. The first 5 episodes were a bit slow, as the rules were slowly introduced to the audience. Also this was where characters were set up. Then the rest of the series was a test where the characters had their relationships and themselves challenged. I found the dynamic between characters entertaining, and the way the characters bond with each other endearing and justified.
The mystery was revealed bits by bits throughout the test. I had a prediction regarding the living dolls, and in the end I was right (it's actually pretty obvious). Still, the way the mystery was revealed kept my watching and wondering for more.
Overall, fascinating premise with exciting thriller and endearing character dynamics. Hopefully Season 2 will expand the universe more and won't get Promised Neverland's treatment. 8/10.
