This is my personal opinion, art style is odd but fits very well with the story. The story is ok but it lacks some backstory so you cant relate and feel the characters very much so it ends up feeling kinda bland, adding scenes of mc's parents and showing more of the backstory of the 'villains' would make me more sypathetic but as it is I find it hard to. Lastly my opinion on the Mc. It sucks. Its hard for me to think of him as a hero or have any positive opinion of him just due to the fact that he has 0 moral's, he killed inocent people and by-standers making the whole revenge plot feel too wrong and makes him feel like the villain.
TLDR; In short the mc is a villain that and I dont like it
(I got to chapter 27)
