Rias Gremory

Rias Gremory, she has red blood-like hair, green eyes, white skin ( as is with most female anime characters ), DD breasts, and likes to mess with Issei Hyoudou, by saying things along the lines of " If you do this you may play with my breasts as much as you like. " Issei Hyoudou will usually waste his chance by hesitating, while Rias counts to around 5, before she closes up her shirt again.
