NB: I've wrote this review just after watching the first episode (I've dropped it), be aware of it.

Plot: very interesting, mysterious and intriguing.

Animation: unwatchable. Every movement is kind of robotic, smooth but literally nonhuman. The worst work I've ever saw. Especially for a nowadays work, we are in 2021, right?

Drawings: none. Everything is Computer Graphic made. And not so well.

Soundtrack: not bad, at least.

Conclusions: don't waste time watching it, really. This is the worst work I've ever saw. I can't recommend it to anyone. The manga is a way better, the drawings are amazing!
