That's one of the three Kogal Bullies...though not the orange-haired one who owns the cellphone stomped by Izaya (that one is named Yoko).

This blond one is the one who said to Izaya "Osan ga kakennedarou?" (What do you want, old man?)

Hehe, just for memory references.

lol so that one was actually a lesbian? wow surprising

I don't understand; what's misleading about the thumbnail?

It looks like she has four breasts.
