イスカ
Main villain of [[Isuca]] and the second title character, as she shares her name with [[Shimazu Sakuya]]'s "true name" (this being one of several mysteries about her). She's a western mage who's out to get Sakuya's eastern-mage family. As Sakuya is to [[Shana]], Isuca is to [[Hecate (shakugan no shana)|]] -- they even wear similar [[hat]]s.
