This series contains frequent female nudity and occasional male nudity. Genitals are usually obscured and when they are shown they are without detail. However, breasts/nipples and buttocks are shown often and in full detail. Female characters are also seen in swimsuits, in underwear, and at times getting undressed. Camera view often focuses on rear and chest.

One female character who is a teenage high school student (with braces nonetheless) is briefly seen fully nude. Her buttocks and breasts are shown in detail while her pubic area contains no detail.

This show contains graphic violence throughout. Characters are shot, stabbed, and torn apart by gruesome-looking creatures. Blood is splattered and body parts are scattered. Not on par with some other extremely violent anime shows, but definitely violent enough to reach or exceed an R-rating.

Smoking and alcohol are present but are never focused on or emphasized.
