Kuisha Abaddon

Kuisha Abaddon is a character from High School DxD, serving as the Queen in Sairaorg Bael's peerage.

She is a pure-blooded Devil from the House of Abaddon (one of the Extra Demons families, outside the standard 72 Pillars). Kuisha is depicted as a beautiful young woman with blonde hair usually tied in a ponytail and blue eyes (appearing green in the anime adaptation).

She is extremely loyal to Sairaorg, deeply respects his strength, and shows signs of strong affection toward him (noted by others like Rias as potentially romantic, though it's more one-sided in the source material). As a powerful high-class Devil and one of the promising young "Rookies," she possesses strong demonic powers, including abilities related to elemental control, creating "holes" (spatial voids), and reflecting/absorbing/redirecting attacks.

She appears mainly in the light novels (prominently during Rating Game arcs) and the anime adaptation in High School DxD Hero.
