In one episode a girl is implied to offer herself for sex in change of a drug, but the drug dealer refuses.

A lot of bloody violence and some gory scenes, especially in the last half, however the gore usually comes up only once or twice in each episode.

While in the original DVD releases the goriest scenes are in black and white, the uncut version shows all the gore in full color.

Mild and infrequent language such as "damn" and "hell" is used on few occasions.

This is a very dark, eerie and disturbing anime that might impress viewers, even the not so young ones.

Some scenes/episodes are violent or have disgusting elements.
