Cendrillon

Cendrillon is a Gremlin magician who first appears in volume 3 of Toaru Majutsu no Index: New Testament. She uses spells based on the story of Cinderella, mostly based on dance and dresses.


She is turned into a human table by Marian Slingeneyer, but later recovers her human shape thanks to Ollerus. This enables her to disassemble her body to the point that it becomes things like cooking ingredients, which can be then "cooked" by anybody to restore her back.
She uses this ability in volumes 5 & 6, but a miscalculation in the "recipe" leaves her with a younger-looking body.
