A number of nude scenes are shown throughout the series, with anatomically-correct breasts. Episode one opens with two nude female characters kissing and, presumably, having sex.

The Cthulhu (Cthuwolf in the English dub) utilize bizarre monsters which enter a person's body and imitates them. When these monsters show themselves, they graphically tear their host body apart. There are also some scenes of robot action, but that never goes beyond PG-13 level.

"Damn" and "hell" are spoken occasionally.

None.

The Cthulhu monsters are very frightening in design and behavior.
