A main female character wears nothing but lingerie for almost the entire length of the arc. We see frequent close-ups of her breasts/buttocks.

There is frequent humor involving breast size.

A boy wants to lick a girl's wound in a slightly sexual matter (due to his vampire nature, the cut would heal), however backs out at the last second.

The cover of an erotic magazine with a nude woman (non-detailed) is briefly seen.

A girl is briefly seen getting dressed (her breasts are partially blocked from view).

There are two notable extended scenes of strong gore in Nekomonogatari. One occurs in which a man is attacked and loses his arm/sprays a significant amount of blood. However, the scene occurs in a darkly lit room, and the blood is portrayed as black, reducing the impact.

A man is attacked and ripped in half, spraying blood all over a room. We see the bottom half of himself split from his body as the top half is still alive. This time, the blood is red/can be clearly seen, and the impact is much stronger.

A girl is seen after being hit by her father with blood dripping down her face.

One use of "bastard" in the official subtitles.

A character frequently has a cigarette in his mouth, though it is never lit.

The scene in which a character is ripped in half is likely to disturb/shock children and more sensitive viewers.
