The character design is poor. he isn't a complex character, we know very little besides the fact he used to work in construction. completely one dimensional. What's more he doesn't react or think like the average human being he is put out to be, he makes psychopathic and completely immoral decisions, doesn't care who he hurts and enjoys inflicting pain in himself. He doesn't have any flaws apparently. it's bad writing choices. The writing itself isn't poor, but the pacing is, he spends 25 chapters with a bunch of nobodies, nearly half the story is about a tournament, and he has yet to meet one of the main characters and Canon has yet to begin. complete and utter letdown.
