Rias Gremory

Rias Gremory (リアス・グレモリー, Riasu Guremorī) is the main female protagonist of High School DxD.

She is the Gremory Clan's heiress after her oldest brother, Sirzechs, took the position of Lucifer. Rias is the sole daughter and youngest child of Zeoticus and Venelana Gremory, the aunt of Millicas Gremory, and the maternal cousin of Sairaorg and Magdaran Bael.

She became known as the Crimson-Haired Ruin Princess, because of the color of her hair and Power of Destruction. Now, Rias is a first-year College Student at Kuoh Academy, the former President of the Occult Research Club, and the school's Number-One Beauty, as well as one of Kuoh Academy's Two Great Ladies alongside Akeno Himejima. Rias is a beautiful young woman with a voluptuous body, white skin, blue eyes (blue-green in the anime, season 1-3) inherited from her father, Zeoticus, and a buxom figure. Her body measurements are [B99-W58-H90 cm] [B39-W23-H35 in]. Her body weight is [58 kg] [128 lbs].

Her most distinctive feature is her long, beautiful crimson hair, which she also inherited from her father, 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' height is 172 cm. (5 feet 8 inches), making her one of the tallest female characters of the series.

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, especially when she has a desire to sleep with Issei.

On some rare occasions, Rias wears glasses when she's deep in thought, as she feels they make her mind work better despite having perfect eyesight. As a Devil from the House of Gremory[2], Rias is very kind and compassionate, especially to her servants and people close to her. She gets angry and violent whenever people insult her or her peerage, showing a fiery side to her. This also plays into the fact that she dislikes cruelty towards people, as shown with her disgust over Marius Tepes, who abused his own sister for his own benefit, and how she killed the Fallen Angels, such as Mittelt, Dohnaseek, Kalawarna, and Raynare for their cruel treatment of Issei. Rias also holds great sympathy towards Sairaorg and his mother Misla Bael for how badly they were treated by the Bael clan.

Rias 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 (as revealed in Volume 2 of the novels) is because there, everyone sees her as Rias, not as a Devil or as the Crimson-Haired Ruin Princess. Due to this and the fact that the only men who showed interest in her were interested in her due to being the Heiress of the House of Gremory, Rias soured on the idea of finding a lover!
