I liked the story, watched all in the same weekend (12 episodes, no boring fillers).
I thought the main character would be the hybrid guy from the netflix thumbnail, then I though it was the cliche cool cold swordman, but it is more about the the girl he rescues and the backstories of the people she meets and hers. His character is there to protect her when something shows up, this isn't dbz, no battle lasts more than 5 mins. Except from one minor antagonist added at the end of the story to give them a goal, everyone has something to tell, no one is just evil.
The only problem is that they used 3D for the background and creatures (they look really unsetting) and 2D cell shading for the characters. Netflix has been doing this with other animes (f.e.: Ajin and Godzilla), not sure if because it is easier or because they think it looks cool (it doesn't). Once you get into the story, you forget about the art (it only annoyed me the first 2 chapters, though I have seen other animes like this one so it wasn't that weird).
