Elegy serves as a General class Opast demon under Reiga's command. This high-ranking entity identifies as transgender, possessing both male and female genders, a fact explicitly confirmed within the narrative. Elegy exhibits a pronounced fixation on aesthetic beauty and strength, expressing disinterest in battles lacking artistic merit. Physically, Elegy possesses light blue hair and alluring silver eyes. A whip serves as the primary weapon, wielded with significant speed and force. Magical abilities include summoning two gigantic skulls, dissolving into butterflies, and casting illusions or trance-like states to deceive opponents. Elegy displays typically cold and dismissive behavior towards others, often ignoring them entirely, alongside noted sadistic tendencies. Elegy particularly enjoys inflicting pain through whipping, often targeting men. A significant aspect involves an obsessive attraction toward Luka Crosszeria, another high-ranking Duras. Elegy professes love for Luka, despite such emotions being considered foreign among the Duras. This fixation drives several interactions, though Luka remains devoted solely to Yuki. Elegy provided blood to the Opast Hyde, granting him temporary enhanced power. Initially aligned with Reiga's forces against the Giou Clan and their Zweilt Guardians, Elegy participated in key battles. However, Elegy's allegiance shifted during the final conflict. When Reiga altered his objectives to prevent Lucifer's summoning and protect Yuki, Elegy, alongside fellow General Cadenza, joined forces with the Zweilt Guardians. This alliance aimed to thwart the antagonists Suzaku and Luze, who sought to use the three grimoires (Key of Solomon, Key of Enoch, and Key of Raziel) to summon Lucifer and destroy humanity. Elegy's ultimate fate remains unspecified within the available information.
