Basically... there's a vampire queen with the body of a child residing in a world based around horror movie monsters(her castle is even called Castle Tepes, she's related to her world's version of Dracula, and she has a ghost maid under her employ among many other monster-based servants. Also lots of gothic architecture). She's asked the UMMA to supply her with agents and anyone else willing to help protect the Eye of the Serpent, an artifact passed down through her family lines, from Shadow Eternity, who is seeking to obtain it for reasons that the UMMA currently does not know.
