Gang leader of the largest Sukeban group in the city, and former friend of Izumi "Skylar Spark" Rokujou, though at the time she was unaware of the latter's true identity. This reveal has caused her to become quite bitter.

Asuka has a chip on her shoulder regarding anything to do with the Rokujou Group, blaming it for each of the misfortunes that have befallen her ever since it began occupying the part of the city she lived in. Since then, she has accumulated a group of like-minded and similarly disenfranchised youths under her leadership, which has grown to encompass many of the different street gangs wandering the area.

Asuka's often sarcastic and caustic, but really she's just a deeply hurt person. Preferably her voice should be on the deeper side with a rough edge. Outside of sudden outbursts of emotion, the volume of her speech stays consistently low in a drawl.
