There is a scene where it is implied that Eric's love was raped, though not shown in great detail.

Martial art fight scenes are usually showed in each episode. Some gunplay also.

Some uses of "Damn"

Eric's love was killed and made to look like it was a heroin overdose. Eric collects this feeling along his way and transfers the effects of that pain onto an enemy. The man shakes in painful sensation and mutters ramblings from the effects.
