Oh yeah, I've got the OVA of this. It was pretty good.

From what I know, the series was originally a series light novel and the anime covers the first volume, Demonic Princess. There were about about two or more novels in between this one and the OVA, where Lancely, the daughter of Akane and Sherice is introduced. There was also a game based on this one.

The other ones have also been made into manga, such as here:

Though no one's translated them.
