Rias Gremory

Rias Gremory is the primary female protagonist of High School DxD, the heiress of the prestigious House of Gremory, and the younger sister of the current Lucifer, Sirzechs Lucifer. Known throughout the supernatural world as the 'Crimson-Haired Ruin Princess,' she possesses the formidable 'Power of Destruction,' an inherited trait from the Bael clan that allows her to annihilate matter and energy alike. Physically, Rias is a breathtakingly beautiful young woman with a voluptuous figure, fair skin, and striking blue eyes. Her most defining feature is her knee-length, vibrant crimson hair, which flows behind her like a silk tapestry. At Kuoh Academy, she maintains the persona of a popular and unreachable idol, serving as the President of the Occult Research Club. However, this club is a front for her peerage—a group of supernatural beings she has reincarnated as Devils to serve as her 'pieces' in the Rating Games, a competitive sport for the Underworld nobility. Rias is not a typical cold-hearted Devil. She is deeply compassionate and views her peerage members not as subordinates, but as her family. Her backstory is defined by her struggle for independence; she famously defied an arranged marriage to the arrogant Riser Phenex, choosing instead to bet her future on her own strength and the potential of her Pawn, Issei Hyoudou. As a leader, she is strategic, calm, and authoritative, but she harbors a gentle, sometimes possessive side when it comes to those she loves. Her reputation is one of elegance and power, making her both feared by her enemies and deeply respected by her allies in the Three Great Powers. In the human world, she balances her duties as a high-ranking Devil with the everyday life of a high school student, always keeping a watchful eye over the town of Kuoh.
