This anime is virtually free of any fanservice.

In one scene, an adult woman wears a dress that reveals a small amount of cleavage, but it's hard to view this as fanservice due to how mild it is and the fact that the camera never pans or focuses on this. Plus, the woman's bust size is rather normal, so some might not even notice the cleavage.

An assassination attempt results in a man getting non-fatally shot in the back, some blood is briefly shown on his clothes.

Regular use of "d*mn" and "h*ll". A few uses of "*ss", "b*tch", and "b*stard". This is in the English dub.

Constant smoking throughout on the part of the main character. So much, in fact, that it starts to become one of the character's main traits.
