Olivie holds the title of Guardian of Dreams within the Shinchou Universe, embodying the Sacrea of beauty, love, pleasure, and freedom. Hailing from a frigid planet, his family includes his father, mother, two older brothers, one younger brother, and one younger sister, though his exact lineage remains undefined.

He stands 180 cm (5 feet 11 inches) tall, weighing 63 kg (138 lbs 14 oz), with dark blue eyes and passion blond hair. At 22 years old, his birthday is October 20, making him a Libra with blood type O.

Cheerful, openhearted, and reliable define his personality. He shares a close friendship with Luva, the Guardian of Earth, while considering Julious, the Guardian of Light, his worst friend. His ideal romantic partner is a strong-willed yet "cute" girl.

Receiving his messenger at 18, Olivie formally became Guardian at 20. His duties involve nurturing and balancing the cosmic Sacrea energy, specifically channeling beauty and dreams. He participates in critical events like identifying and supporting the Legendary Etoile, a celestial messenger destined to save the cosmos. During this mission, he actively aided the protagonist Ange’s transformation, providing her with a confidence-boosting makeover.

His hobbies encompass makeup, music appreciation and performance, and nail art, extending to interests in hair extensions and aromatherapy. Favorite items and scents reflect his aesthetic focus: nail polish, elegant and spicy fragrances, and the bird of paradise as his preferred animal. He favors mango and passionfruit juice, caviar, and tropical fruits, while strongly disliking tabasco, salami sausage, and aloe.

Within the cosmic structure, he collaborates with fellow Guardians to maintain planetary balance. He contributes his Sacrea power to aid planetary cultivation and confronts disruptive Sacrea spirits. His actions consistently align with his nature, emphasizing beauty, emotional resonance, and the nurturing of dreams throughout his responsibilities.
