Rias carries an air of confidence because she is next in line to the Gremory family, but she is also kind and caring. She treats her peerage like family, caring for them deeply.

She also exhibits this mix of power and gentleness in her personal life. Rias can be a jealous girl in love, especially when other girls get close to Issei. But she is also understanding, allowing Issei to have his dream of having a harem of beautiful girls.

Rias dreams of becoming the best Rating Game champion together with her peerage. She also wants others to see her as her own person, not just part of the high-class family.

Her long, bright red hair is a standout feature. It reaches down to her thighs, with one piece sticking up like a cowlick. Framing her pretty face are loose bangs on the sides. Her deep blue eyes (shown blue-green in early seasons) are intense but gentle.

Adding to her striking looks are her tall 172cm (5'8") height and curvy yet fit figure. Rias noticeably and recurringly gets looks from men and women wherever she goes.

Rias is a strong fighter who can use offensive and defensive demonic powers. She also has unique abilities like Extinguished Star and can transform in different ways. She has trained hard, recently earning the highest rank of Ultimate-class Devil and becoming more powerful than ever before.

The following highlights the full scope of her powers and abilities:

  • Great Demonic Power: Rias received a lot of demonic power from her family. With only her natural talent, she has enough power to become one of the top devils.
  • Power of Destruction: Her signature ability allows her to disintegrate almost anything - matter, energy, souls, and abstract concepts. Rias has mastered compressing this power into fast-firing projectiles.
  • Extinguished Star: Rias's ultimate attack creates a big sphere of red and black energy that chases targets with strong force. Its power exceeds the Rating Game's retiring system.
  • Master Magician: Rias excels at defensive magic barriers, memory control, and other devil magic supplemented by her demonic powers.
  • Superhuman Abilities: As an elite devil, Rias possesses enhanced strength, speed, durability, and healing. She can fly using devil wings.

To further augment her formidable power, Rias employs powerful equipment and gear. By synchronizing with Issei's power, she can access her signature armor, the "Crimson Extinct Dragonar." This armor greatly enhances her abilities and enables her to use Issei's Boost, Transfer, and Penetrate techniques.

Rias can also use the strong "Forbidden Invade Balor Princess" form by combining with Gasper's shadows. This form gives her eyes the ability to stop time. Additionally, she gains the ability to control her attacks more.


  • Her nickname, "Crimson-Haired Ruin Princess," comes from her mother's nickname, "Flaxen-Haired Ruin Princess."
  • The author did not originally plan for Rias to be in the High School DxD series.

  • As a child, wild camels hurt her when she snuck out to a farm, causing her to develop a fear of camels.
  • Rias wants to have a traditional Japanese-style wedding, ideally taking place in Kyoto.
  • In a popularity poll, she ranked #1 in the overall character, heroine, and pairing with Issei categories.
