Rias Gremory is a Devil from the Gremory Clan, a family of pure-blooded Devils, and is known as the Crimson-Haired Ruin Princess. She is a third-year student at Kuoh Academy, the President of the Occult Research Club, and the school's number-one beauty as well as one of Kuoh Academy's Two Great Ladies.
Although Rias has worn various types of clothing throughout the series, her most commonly worn outfit is the Kuoh Academy girls' school uniform, which consists of a white long-sleeved, button-down shirt (short sleeves for spring/summer) with a black ribbon on her shirt collar worn under a black shoulder cape and a matching button-down corset, a magenta skirt with white accents, and brown dress shoes over white crew-length socks. Rias also tends to wear seductive lingerie and thongs, Rias is a beautiful young woman who appears to be in her late teens with white skin, blue eyes (blue-green in the anime) and a buxom figure. Her most distinctive feature is her long beautiful crimson hair that reaches down to her thighs, with a single hair strand (known in Japan as ahoge) sticking out from the top. Her hair also has loose bangs covering her forehead and side bangs framing her face.
Rias is shown to be kind, soft, loyal and caring to her servants. She rarely ever raises her voice when she's speaking, even when she's displaying her serious side. She thinks of Issei as a special person, and always gets jealous when girls are around him, becoming a totally different person when she sees him and other girls together, or when it comes to training. Despite her mature stature like a woman, Rias tends to act her true age and become frustrated whenever girls flirt with Issei.
She is proud of her family's name, but she does not like being seen as Rias of the Gremory Family. The reason for her living in the human world is because there, everyone sees her as Rias, not as a Devil or as the Crimson-Haired Ruin Princess. Despite being seductive like Akeno, both of the girls are still innocent to love, as both of them become their age whenever around Issei or on a date with him.
