But before you read it, are you able to deal extremely graphic (although it's drawn) imagery, there is a lot gore, a couple of times in the series torture happens, although you don't see it, in the sequel manga a character is raped, the main character suffers alot, and trajedy strikes often, but it does have comedy here and there, it's just not too common. But the story is a roller coaster you don't want to stop riding, I'm just warning you in case your queasy about violence, or not comfortable with the said themes.
