Olivia is a composed and calculating individual, known for her sharp tactical mind and her merciless approach toward enemies. As one of the Four Heavenly Kings, she maintains a calm, almost expressionless exterior that often makes her seem unshakable. However, Ard having known her for over 3,000 years understands that her true nature is far more nuanced.

When in a bad mood, Olivia becomes unusually talkative and animated, while in moments of happiness, she turns quiet and mischievous, often playing harmless pranks. Her emotions can also be read through the subtle movements of her cat ears and tail, which act as a silent giveaway to her thoughts.

A perceptive and intelligent woman, Olivia immediately suspected Ard’s true identity as the reincarnated Demon Lord upon meeting him. She has long been a supportive yet strict “older sister” figure to him willing to be harsh when needed but always guided by genuine care. She also has the humility to acknowledge her own mistakes, such as when she realized she had unintentionally placed emotional distance between herself and Ard.

Despite her disciplined behavior, Olivia can be caught off guard, especially when confronted with Ireena’s sincere innocence. Interestingly, she has a surprising soft spot for sweet potatoes, to the point of becoming childishly competitive over them, once even seeking to punish the Demon Lord for eating hers.

Over 3,000 years ago, Olivia vel Vine was one of the Four Heavenly Kings who served directly under the Demon Lord Varvatos, acting as his trusted right-hand and elder sister figure. Orphaned at a young age, she met Varvatos in the slums, and the two were later taken in by Aisha. Despite Aisha’s flaws as a guardian, Olivia developed a strong bond with Varvatos and accompanied him through countless battles, earning a fearsome reputation for her unmatched combat prowess and strategic brilliance.

During the war against the Evil Gods, Olivia fought tirelessly alongside Varvatos, helping him unify the world under his rule. However, as his overwhelming strength grew, a distance formed between them, leading her to impose boundaries despite their shared history. Even so, her loyalty never wavered.

In the present day, after Varvatos’ reincarnation as Ard Meteor, Olivia assumed the guise of a teacher at Laville National Academy of Magic. She quickly recognized Ard’s extraordinary abilities specifically his use of double-casting, a long-lost technique and began suspecting his true identity. Although initially cautious, she soon resumed her role as his mentor and protector, offering guidance in both magic and personal matters.

Her history with Ard gives her unique insight into his strengths, weaknesses, and emotional struggles, making her one of the few people capable of challenging him both in battle and in mindset. Despite her calm and composed exterior, Olivia remains deeply protective of him, just as she was in the age of the Demon Lord.

Olivia is a striking beast woman distinguished by the sleek black cat ears atop her head and the long, jet-black hair that cascades down to her waist. A slender, graceful tail extends from her lower back, complementing her feline features. Her complexion is a pale, almost translucent lily-white, enhancing her refined and otherworldly presence. Standing at roughly the same height as Ard, she is considered tall for a woman, carrying herself with an elegance that reflects both her noble bearing and her status as one of the Four Heavenly Kings.
