I'm not very far at all, so think of this as my initial impressions. I wish I could review volumes individually, but here we are.

The girl from the other side is a bit bland, but the charming character interactions make up for it for me. The art is the worst part, but the story isn't much better.
It's very hard to distinguish characters from backgrounds sometimes due to the amount of black everywhere.
Honestly, this should've been a one off. Even by the second volume, the story is obnoxious, pretentious and a bit ridiculous. It is overrated, but it holds some value-

The first volume, at least.
