A nice read.
I especially liked the evolution of the main character. I also liked the facial expressions, it's very japanese.
As for what i disliked, well the sister's bullshit with men. Not that i care about it specifically, i just dont see the point of adding it to the story. What does it bring? Secondly.... well, we are left hungry for more. This feels like a story arc, not the whole manga. Well, at least it didnt drag for too long to the point of making Fable a completly different character, a common flaw in mangas.
7/10. It's John Wick, with a bit of social commentary of the side.
