Ayumu's first enconter with her is by bumping on her breast, and she didn't even get mad or happy. The strongest masou shoujo in Netherworld and also Yuu's acquaintance. She actually lives in Human world and busy with making doujin for winter Comiket. Actually, she doesn't have any offensive-type magic. Her ability is negating magic. It is also believed that she's also responsible to suppress Yuu's magic. Ayumu also saw Nene naked by barging into the bathroom and got his ass kicked. However, she forgives him because she can calmly under stand the situation.
