Medusa's child and the Demon Swordmaster, serving as the meister of the Demon Sword Ragnarok. Crona's sex is left ambiguous, giving Crona several androgynous qualities, although Crona is seen wearing a skirt during Crona's childhood flashbacks. In the Yen Press translation of the manga and the Funimation dub of the anime, Crona is referred to as a "he" to simplify the matter. Crona is extremely reclusive, expressing uncertainty at interacting with others and dealing with certain situations. At an early age, Crona's blood was replaced with black blood from Ragnarok by Medusa as part of her experiments to create a kishin. This blood can harden to protect Crona from damage and be used as additional projectile weapons through external wounds, though it causes Crona to go insane for brief periods.
