Ayumu's first enconter with her was bumping into her breasts. She's one of the strongest masou shoujo in Netherworld and also Eucliwood's acquaintance. She lives in Human world though, busy making a doujin for winter Comiket. She doesn't have any offensive-type magic. Her ability is negating magic. It is also believed that she's also responsible for suppressing Eucliwood's magic.
