Deldry is a Holy Knight and a member of the Pleiades of the Azure Sky, who serves under the Assistant Great Holy Knight, Denzel Liones. Deldry is a tall young woman with a slender figure. She has blues eyes and bright green hair that's tied into a ponytail with a red bunny-ears headband. Her attire, as opposed to the armor Holy Knights usually wear, consists of a metal purple strapped shirt along with a short skirt, black arm wears with blue frills, and a short red scarf tied around her neck. She also wears armor on her legs. Deldry is seemingly confident, showing no expression of fear and confidently anticipating a coming battle with the former Great Holy Knight Dreyfus, despite knowing he is possessed by a demon. She is playful and has no hesitation in abusing her powers against others, even though it gets her in situations she'd rather not be in. Despite that, she was greatly disturbed of Waillo's flirting towards her about getting married.
