Runeas Gremory

Runeas Gremory is the legendary first-generation ancestor of the Gremory bloodline and the original progenitor from whom the entire House of Gremory descends. As the founding Devil of the clan, she is less a distant historical figure and more a living embodiment of the Gremory family’s personality, excess, and charm. Runeas has a playful, mischievous, and teasing nature, delighting in pranks and informal behavior rather than fear or intimidation. Despite being an ancient and immensely powerful Devil, she is not cruel or frightening. On the contrary, she holds a deep, almost indulgent affection for her descendants, openly doting on them and addressing them with pet names—calling her descendant “Rias-chan” and even referring to Rias’s future husband as “Issei-chan.” Zeoticus himself describes her temperament as having a distinctly “devilish personality,” implying both charm and troublemaking rather than malice. Her demeanor is notably childlike, especially after awakening from long periods of slumber. She craves stimulation and amusement, often demanding that her descendants entertain her. These demands are intentionally embarrassing or absurd, such as forcing Zeoticus to dance in the Gomorin costume (a habit that began when he was still a child, including singing for her), having Millicas sing for her, or ordering Rias to make Issei demonstrate his infamous magic techniques in front of her. She treats these situations as harmless fun, clearly enjoying the discomfort and reactions of others. Runeas also possesses an eccentric obsession with camels, which directly shaped the Gremory Clan’s unusual cultural traditions. Her fondness for the animal became so extreme that it evolved into a family rule, mandating that female descendants ride camels when traveling, as Runeas believes it dramatically emphasizes their cuteness and presence. This bizarre decree is followed more out of reverence and fear of her displeasure than logic.
