This figure has a complicated backstory. Phantasmoon is a spoof magical girl, which is itself a spoof inside Carnival Phantasm, a spoof series by Type-Moon featuring the cast of Tsukihime and Fate. Phantasmoon is the alter ego of Arcueid the vampire (the titular 'Moon Princess,' the literal translation of Tsukihime). The irony of a tragic and terrible vampire as the Magical Girl protagonist of a show within a show making fun of a third show is almost painful. But, it works.
