Siris is a tall young woman with long black hair with a dark blue tint and brown eyes. Her hair features five thin ponytails going around her head, which are held up by a golden hair accessory on top of her head. Her outfit consists of a white top with black accents that is modeled after a Chinese cheongsam, red shorts, and armored, knee-high boots with matching gauntlets. The top features a diamond shape on the chest area, giving view of her breasts and cleavage.
Siris is mostly seen with a giant Zweihänder that is mounted on her back when not in use. It features a black blade with silver edges, and has a black hilt with a red handle.
Despite being a Knight, Siris does not uphold a Knight's code of honor and is willing to follow the orders given to her without any doubt.
Not much was revealed about her past, only that at one point in time, she was revived as a Devil by Riser.
She appeared with Riser and the rest of his peerage at the Occult Research Club room.
During the Rating Game between Riser and Rias, she, along with Mihae, Ni and Li, fought Issei, easily overpowering the latter until Issei triggered the Boosted Gear Gift. They were then defeated by the combination attack between Issei Hyoudou and Yuuto Kiba.
