Background

Vivian is the eldest daughter of the Colin Family and a granddaughter of Caesar Colin. Raised as the family’s future heir, she was widely regarded as exceptionally gifted, courageous, and more mature than her younger brother Nan Fu in both intellect and strength. Her confidence developed into considerable arrogance, reinforced by the Colin Family’s status and her early Gold-rank strength. 129 138

After discovering her father’s infidelity and Leon’s existence as her half-brother, Vivian treated Leon as an affront to the Colin Family. She allowed herself to become a pawn of the Dragon Family and ambushed Leon following the fall of Black Wind Fortress, intending to kill him. 129 133

Leon decisively defeated her with Holy Light magic, leaving her injured, humiliated, and temporarily restrained by a magic-suppressing collar. While recovering, Vivian realized that Leon—not she—had been deprived of his rightful family, inheritance, and Blood Clan birthright. She came to regret both her accusations and attempted murder. 134 138

When they met again at Professor Adonia’s workshop, Leon treated her politely as though they were strangers, allowing Vivian to approach him on her own terms. She later asked to call him “Brother” in private, beginning their reconciliation. 138 140

Appearance

Vivian is a young Blood Clan noblewoman with purple hair, crimson eyes, pale porcelain-like skin, and small visible fangs. Her appearance can shift sharply between an elegant, doll-like young lady and an intimidating vampire combatant. 236 457

• Purple hair, often worn loose or beneath a headscarf.
• Crimson or wine-red eyes that deepen in color when her power rises. 457
• Small tiger-like fangs that show when she smiles or becomes excited.
• Frequently wears formal dresses; favors dark colors, though she also selected a light-blue dress with silver trim while shopping with Leon. 245
• Redesigned her Hospital Knights nun habit into a fitted black-and-white uniform with a shortened hem for mobility. 622

Personality

Vivian is proud, competitive, impulsive, and accustomed to getting her way. Before reconciling with Leon, she was known throughout the academy as a formidable “witch” whose reputation alone frightened other students. She is quick to fight, especially when challenged, and initially approached problems through intimidation or force. 138 457

She is intensely attached to Leon and seeks his praise, approval, and attention. This attachment often manifests as jealousy toward Mia, Erin, and other women close to him, though Leon’s guidance gradually pushes her toward greater restraint and responsibility. 236 245 576

Despite her poor academic discipline—she skips classes, neglects homework, and struggles with unfamiliar human vocabulary—Vivian is observant, clever, and capable of learning from experience. Her work with refugees and the Saint Colin Hospital Knights reveals genuine compassion and a growing preference for earning respect through aid rather than fear. 508 532 573 619
