Every character in this manga is trash. All of them are disgusting in some way. But still I felt identified with all of them. I can see myself portrayed in every flaw, in every vile and selfish action, in every sin and sorrow. Oyasumi Punpun is a weird mirror in which I can look to my inner demons horrified.This shit broke me. I want to become better than this but I have no hope that it will happen.

The story and the art are more wonderful than it deserves to be.
If you are a broken person you will love this manga as much as it will hurt you.
