at first I thought this is a vengence fulled guy finds himself in a rather calm world but author went noooo it needs to be more edgyyyyyyyy and threw that "world" to us and I was heavily dissapointed
well edgyness didnt stop there and I dont think author will stop anytime soon it just gets worse and worse
I wonder what was author thinking when he came up with this
there are bunch of manga similar in both premise and world building but I dont think anybody would think this would be a good idea then starts drawing
