It's a classic shonen arc but very well executed I think, I mean when you stare and I got the money and then drew my name Yeah there is a great balance and great variety of characters with a very refreshing take on the female roles, not following the big boob damsel in distress pattern but actually introducing a very unique and impressive cast of male and female characters alike and on top of that the enemy also doesn't shy away from graphic imagery and a darker sub tone.
