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 3rd year Student at Alliance Academy and the President of the Occult Research Club. And she was also known as the School's Number One Beauty and one of the Two Great Ladies while studying at Kuoh Academy along with Akeno Himejima.

Rias is a beautiful young woman with a voluptuous body, white skin, blue eyes 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.

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.

## Personality

As a Devil from the House of Gremory, 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.

## Powers & Abilities

**Great Demonic Power:** Like Sirzechs, Rias inherited exceptional demonic power from her parents and is adept in using it, even for a High-Class Devil. After Issei transferred power to her, her demonic power increased to where it rivaled an Ultimate-Class Devil, shaking the ground, and reaching Satan-Class. Azazel noted that even without training, Rias has the potential to become one of the highest class devils using natural talent. She was capable of overpowering Ultimate-Class Devils wounded by Crom Cruach, while in her Balor Princess Form, could keep up with Fenrir at 80% percent power.

* **Power of Destruction**: A unique demonic power, which allows her to erase and disintegrate matter, living and inanimate things, often releasing massive blasts able to erase massive targets. Rias has improved her Power of Destruction to the point of being able to compress it into multiple bullets, lessening their attack range, but Kiba noted those without enough power would vanish from one of them.
	+ **Extinguished Star**: Rias' Ultimate One-Hit Kill Technique, which was caused from the influence of draining Issei's dragon power. She activates it from focusing Power of Destruction into an enormous sphere that has crimson and black aura swirling in it. Despite being a slow technique, Extinguished Star has a strong attractive force that pulls targets towards it, before disintegrating them similar to a black hole. Its destructive power has been said to surpass the Rating Game's retiring system.

* **Castling:** Due to being the King of her own peerage, Rias has the ability to use Castling, which allows her to swap locations with one of her Rooks. She first used it during Nilrem's attack on Kuoh Academy, swapping places with one of her unused Rook pieces;
* **Healing:** Rias is capable of healing others using her demonic power, it requires her embracing the injured person and both parties to be completely nude in skin to skin contact for better effectiveness. She has shown to be able to heal fatal wounds such as when Issei was struck by a Light Weapon;
* **Oppai Beam**: Rias has gained the ability to project a red light from her breasts, which recharges Issei's energy. Each use of this power causes her breasts to temporarily shrink in size, however, her breast size will restore itself after a few days of rest.
* **Memory Alteration:** Rias has shown that she has skill in memory alteration, using it on Issei's parents;
* **Summoning:** Rias is capable of summoning her bat-like familiar;
* **Defense:** Rias can create several barriers able to protect herself and her servant from Katerea's self-destruction spell during the Three Factions Conference.
* **Transformation:** She can use her demonic power to change the color of her hair from crimson to blonde.
