This show perfectly encapsulates how a Dorodere character should be written, developed, and implemented into an anime. For those who don't know what a Dorodere is, it is a type of character who acts nice and sweet on the outside but are deeply disturbed from inside.
In this slice-of-life thriller horror series, we follow two nameless high school girls, where as the plot progresses, we see their true natures, which is truly outstanding as the show shines during their conflicts. Not being able to talk adds a layer of mystery and intensity, as their true personalities that could be heard through their voices are intentionally blocked to evoke those kinds of emotions for us viewers,
The thing I was surprised the most about this series is the major plot twists in the middle and towards the end, truly revolutionary and it's not often you see twists like that in shows that are in MAL's top 50. If you can move past and ignore the jarring PS1 CG graphics, this will be a blast to watch.
Overall, it's a must-watch series and I highly recommend it. I'll give this a 3/10
