Rias is a very kind and compassionate optimist, 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.

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 (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, until meeting and falling in love with Issei. According to Akeno, Rias originally said that all men looked the same to her as Rias said that Issei is the only exception due to her thinking of him as cute.

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 becomes frustrated whenever girls flirt with Issei. While Rias is usually calm and mature in most situations, she loses her mature aura and presence when she sees any girl (especially Akeno) flirting with or seducing Issei.

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 (It is revealed in Volume 3 of the novels that the Gremory Family and their servants are beings with extraordinary affection among the Devils, so 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.
