a strong male character not to be shy and he wants to have sex with her implying this through the phrase "i want to make you mine"

There is violence between exorcist, demons and vampires but it is all very tame.

There is pretty much no swearing, maybe a few (being like 3-4) uses of the word damn

The fights may be a bit scary for younger viewers but they are all very tame, the most frighting fight is on the last episode but that is the only one you really need to worry about but even that is tamer than most anime
