Some blood splashes for screen transitions but these are potrayed in a non-violent way and it makes sense within the context of the show due to the vampire centric theme..

A recurring antagonist of the show is a vampire hunter who tries to eradicate the vampires by using various medieval weapons (crossbows, catapults, etc.) but never succeeds in doing so.

The whole show is centric around vampires and has an overall gothic theme, however these vampires aren't inherretly potrayed as evil and more cartoonish. Nothing a kid couldn't handle.
