Some slightly suggestive jokes. Nothing explicit.

Some of the women in the show are seen bathing at a few points. During these scenes their buttocks can be seen, but there is no explicit detail and the scenes are not sexual in the slightest. Their breasts in these scenes are covered by bubbles.

Mild overall despite the show being about vampires. A few characters get bitten and there is a little bit of blood but besides that only monsters are ever killed in the show and even that happens rarely. When they are killed they turn to ash.

Very mild. A few uses of "damn" is as bad as it gets.

As one could guess from the cover art, the show is not trying to be scary. A good portion of it is comedy and the parts that aren't are pretty standard "good-guy vs. bad guy stuff". Anyone who thinks this is scary is probably not old enough to watch it in the first place.
