There are quite a few similar points; the Princesses, Kiiru (Spirit of Darkness) and Duzell (Vampire King) and the relationship of the Princesses and their bodyguards. There is also darkness (I don't mean Kiiru) and humour in both. If you like one, you might like the other. It's worth a try anyway.
