The concept itself is good in my opinion (sort of reminds me of deadman wonderland that's actually worth reading tho) but it feels so boring, nothing feels exactly intense, the pacing is eh and the intro, which is supposed to be the main thing to pull in a reader wasn't great either. The main character barely fits the role of a main character and the side characters didn't give much of an impact either. I'd give it a 6/10 at most
