(Volume 1, Life 4) In one of her original early concepts, Rias' design bore a striking resemblance to Tamaki Kousaka from To Heart 2.

Crimson Extinct Dragonar ( 深紅の滅殺龍姫 ( クリムゾン・エクスティンクト・ドラグナー ), Kurimuzon Ekusutinkuto Doragunā): Also known as Crimson Dragon Princess of Annihilation. A combination technique between Rias and Issei, where he uses his Red Wyverns and they sync both of their auras and the Wyverns attach themselves to Rias to create her own female version of Issei’s Scale Mail. The armor acts just like Issei's, boosting Rias' abilities and giving her the ability to utilize Boost, Transfer, and Penetrate until she reaches her limit. Defense: Rias can create several barriers able to protect herself and her servant, such as from Katerea's self-destruction spell during the Three Factions Conference. Now my adorable servants!

The Switch-Princess that only belongs to you. If I can become the source of your power, then that will fulfill my wish. –My adorable Ise." (Volume 7, Life-3) She holds her older brother, Sirzechs, in high regard (despite her older brother's antics of being a siscon) because she deeply cares for him. When she was a child, she was entirely dependent on him and held him in admiration, while also feeling inferior to him at the same time. Due to being spoiled by her father Zeoticus and her brother Sirzechs from an early age, she has a somewhat impatient and selfish personality and because of her bad money spending habit, her mother Venelana and her sister-in-law Grayfia often scold her for her frivolous spending, as her mother reconsidered the amount of money she is allowed as allowance.

Keen Intellect: Rias is a very intelligent and knowledgeable woman, due to being naturally gifted as well as her aristocratic education as the heiress of the Gremory Clan since childhood. When running the Occult Research Club, she is shown to be knowledgeable on occult topics such as supernatural beings like Youkais, Devils, Angels and Fallen Angels. Stealth Expert: Rias has learned how to mask her presence to allow her to remain undetected, as a way to sneak behind and surprise Issei without being noticed.Rias has a driving license and owns multiple cars such as a red saloon and a red convertible being two of them. [15] Rias is competitive and hates to lose, especially after losing her first Rating Game against Riser as she strives to always win, whether it is in sports or Rating Games. She enjoys teasing Issei and Asia (from Volume 3 of the novels onward), but at the same time makes it clear (to Asia or any girl) that Issei is hers, and she does not want to share him at all. The Gremory Family and their servants are beings with extraordinary affection among the Devils, and Rias is no exception. She has no problem with showing Issei her breasts or sleeping naked with him (which she always does according to her and she claims she can't sleep without being nude or without Issei). 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. In the finale of High School DxD BorN, Rias used an armor variant, presumably similar to Crimson Extinct Dragonar, after being manipulated by Issei's evil double. Rias loves participating in Rating Games, as she dreams of becoming the Rating Game champion by defeating the current Rating Game champion; Diehauser Belial, with the help of her peerage. While Rias is a powerful devil in her own right, being much stronger than average High-class Devils and according to Azazel, being able to become a Ultimate-class Devil just on the virtue on her talent alone, Rias suffers a bit of an inferiority complex when she compares herself to her fellow Rookies Four colleagues, as she feels inferior to Sona as a strategist and that she is far weaker in power than Sairaorg. However, according to Riser and Azazel, Rias has a talent for finding and recruiting talented individuals for her peerage, inspiring great loyalty and growing stronger with them as seen in her meeting with Issei. During the Azazel Cup, she was highly evaluated as a scout as she managed to recruit Crom Cruach and Vasco Strada along with 2 Longinus possessors, being praised by the professional critics. She is noted to be a skilled negotiator, as she was able to convince Rossweisse to join her peerage by offering her better working conditions and a better salary compared to her previous job in Valhalla, and while during the Azazel Cup, she was able to convince Vasco Strada to join her team after he declined all prior invitations to participate in the Cup by appealing to his warrior swordsman spirit and offering to restore his youth without using a Devils ability, thus not violating his faith with Strada praising her negotiating skill as a sweet Devil's whisper.

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. Magical Girl Ria!

Grayfia Lucifuge • Euclid Lucifuge • Kuisha Abaddon• Bedeze Abaddon • Mephisto Pheles • Roygun Belphegor Rias' job requests as a Devil are usually to defeat monsters targeting her clients or de-cursing items. [10]Other Skills: As a High-Class Devil, more so the Gremory Heiress, Rias learned a wide arrange of different skills. In the Human World, she learned things no other pure-blood would ranging from housework to gardening, both of which became hobbies. 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. Galatine II( ガラチン II, Garachin II) : A crimson sword able to be used by a devil, which Rias had received from Heaven as a blessing after her engagement to Issei. She plans to pass it on to their future children. Ishibumi describes Rias as being the King, the mother, and the big sister of her peerage all at once. Master Dancer: As a Devil noble, Rias is highly skilled in social dancing. During her and Issei's dancing trial in the ruins of connection, she could dance beautifully with Issei, even leading him in the parts he is inexperienced in to pass the trial.
