Beast Girl Heroine

The Beast Girl Heroine, or as she refers to herself in the kana as the New Heroine (しんヒロイン), is a strange background character introduced in Shinyaku Toaru Majutsu no Index.

She is most likely used by Kamachi Kazuma as comic effect to further exaggerate Kamijou Touma's ridiculous ability to gather women and girls around him when drunk.

Appearance
She is a lithe girl, with wild features. She has disheveled blond hair with large cat ears on them. Expounding on these cat-like features, she has cat-like eyes, smile, a tail, as well as a seemingly leopard skin one piece dress.

Homecoming Arc
She first appears on the streets as drunk Touma, mindlessly wanders to "try" and apologize to the girls that have worried for him. She suddenly appears, and comments on how she doesn't really care for him, but then asks him "to make kitty purr."

She later follows him to his dormitory, where Index sees her and notifies Touma on how, among the girls she brought home, there is someone she doesn't know mixed in. She then introduces herself as the new heroine, apparently climbing on Touma's balcony to get to his apartment. She is most likely shooed away by Leivinia Birdway's subordinates like the other girls.
