Okay okay. This anime is getter some pretty bad hype. I mean from what I have seen. It is better than instant kill in another world IMO but let be honest. This is not a 1* like many are giving it and it certainly is not good either.
I am going to openly admit. This is bad. Clunky animation. A story plot line that constantly pivots and doesn't make sense. Character development that is beyond bad. Romance that doesn't make any sense and isn't clear. The heros back story often comes up but doesn't connect at all to the current plot.
I am not a reviewer so I am not going to break down all the articles of investigation. But just going to say this. If you are on the fence. Just skip. All anime is worth watching from my perspective, but this one should be pretty far down the list. Nearly at the bottom.
