Description
Yue, born Aletia Galdea Vesperitio Avatarl, reigned as a vampire princess over the kingdom of Avatarl until her uncle and subjects betrayed her, imprisoning her within the Orcus Labyrinth under the pretense of shielding her from Ehit, a false god determined to exploit her immortality and prodigious magic as a vessel. After three centuries of entrapment, she was freed by Hajime Nagumo, who bestowed her new name—Yue—to mark her emancipation from a legacy of tragedy.

With the delicate features of a preteen—blonde hair, crimson eyes, and a diminutive frame—Yue’s youthful guise belies her ancient intellect and lethal prowess. Her immortality grants rapid regeneration, making her virtually indestructible, while her mastery over all elemental magics without incantations cements her status as a peerless sorceress, a gift that once fueled her persecution.

Yue’s existence orbits Hajime, her savior, whom she serves with fanatical devotion. Declaring herself his "property," she melds playful affection with vampiric rituals, blurring love and bloodlust. Her protectiveness manifests in merciless retribution against threats, from crushing adversaries’ genitals to delivering fatal blows, underscoring a vengeful pragmatism.

Though dismissive of rivals in Hajime’s harem—mocking Shea, Tio, and Kaori with biting epithets—she forges unexpected bonds: shielding Myu, a child she adopts, and respecting the warrior Shizuku. Fragments of her past reveal a ruler both benevolent and capricious, prone to physically chastising subordinates, yet betrayal left her haunted by abandonment.

Temporarily enslaved by Ehit’s mind control, Yue shattered the god’s influence with Hajime’s aid, later channeling ancient spells to forge a portal to Earth. Post-victory, she marries Hajime, embracing tranquility without shedding her ruthless edge when safeguarding kin.

Spin-offs glimpse her regal history and cryptic ties to ancient rebels, though specifics remain elusive. Her journey weaves loyalty, vengeance, and the tension between unyielding ferocity and flickers of tenderness, etching a path from shattered monarch to redeemed guardian.
