- Despite having the appearance of a witch, she is actually a black cat with exceptionally strong magic powers, including the power to transform into a sexy young woman, leading Maka and Soul Eater to mistake her for a witch and forcing them to start their soul collection over after they collect her soul (which she survives since cats have nine souls). She continually flirts with Soul and moves into Maka and Soul's apartment for this reason, much to Soul's dismay and Maka's jealousy. Despite this, the two are able to generally tolerate her presence, though Soul suffers from nosebleeds whenever he sees her doing something risqué, such as wandering around the apartment naked. She also gets a job at the localcabaret and befriends the employees there. Her magic is largely Halloween-themed, and she utters the chant "pum-pumpkin pumpkin" before casting her spells. She can summon a giant floating pumpkin, which she uses as transportation.
