Description
Dia Viekone hails from the noble Viekone family of the Swoigel Kingdom. Recognized for exceptional magical talent at age ten, she was dispatched to Lugh Tuatha Dé as a magic instructor, commencing a seven-year mentorship. Initially viewing Lugh as unremarkable, her perspective transformed upon recognizing his capabilities, leading to a collaborative partnership in magic development. Their joint research into rune-based spell creation fostered a deepening bond that evolved into mutual affection.

Dia possesses long white hair, blue eyes, and a youthful appearance often mistaken for someone younger, a trait stemming from her hereditary D-Rank skill, Aging Resistance, which halts visible aging after puberty. Her noble background shapes her preference for elegant attire over cute styles and manifests in occasional displays of privilege, such as repurposing her high-class dormitory into a private collection space.

Personality-wise, Dia exhibits strong intellectual curiosity, particularly concerning magic. She initially struggled with loneliness, seeking comfort by sleeping beside Lugh. She demonstrates strategic possessiveness in relationships, accepting only Tarte and Maha as potential partners for Lugh while actively encouraging Tarte's confidence. Her noble upbringing surfaces occasionally in a spoiled demeanor and unconventional sense of propriety. However, she shows diligence in her studies to avoid separation from Lugh and keen perceptiveness, deducing subtle details like Lugh's mana-transfer methods with Tarte. During her kingdom's civil war, she displayed resilience, trusting Lugh's intervention despite initial reluctance to flee.

Magically, Dia ranks among the world's strongest mages. Her mana conversion efficiency reaches 90%, surpassing typical rates of 60-70%, granting superior spell power and precision. This innate talent secured her top academic rankings in magic chanting, exceeding both Lugh and the Hero. Her elemental affinities encompass earth, fire, wind, water, light, and dark. Key innate skills are:
- **Rainbow Mage (A-Rank)**: Enhances mana control and output, allowing temporary mastery of any elemental affinity for one-hour durations.
- **Genius (B-Rank)**: Boosts calculation, reasoning, learning, and creative intellect.
Through Lugh's My Loyal Knights skill, she acquired five additional abilities: Rapid Recovery (accelerated stamina and mana regeneration), Quick Chant, Multi-Chant (simultaneous spell incantation), Possibility Egg (skill evolution potential), and Limitless Growth (surpassing natural ceilings). Despite innovative spell research, she cannot activate new magic first due to backlash; Lugh must initiate spells using his Spell Weaver skill.

Her special abilities include Mystic Eyes obtained via surgery from Lugh, enhancing mana perception, dynamic vision, depth awareness, and slow-motion sight. She co-developed advanced spells like Demonkiller (nullifying demonic regeneration) and Gungnir (a kinetic orbital strike used against Setanta MacNess).

Relationships define significant arcs. After civil war endangered the Viekone family, her father requested her "assassination" to facilitate escape, leading Lugh to stage her death and relocate her to Tuatha Dé territory. There, she was adopted as Lugh's "sister" under the alias Claudia Tuatha Dé, leveraging shared bloodlines through Lugh's mother Esri for credibility. She later became formally engaged to Lugh as his designated head wife. Her bond with her father, Dimior Viekone, remains strong, evidenced by his involvement in her protection. She maintains a strategically tolerant dynamic with Tarte and Maha, Lugh's other fiancées.

Dia evolved from a detached teacher to an emotionally invested partner. She proactively advanced their relationship, culminating in a physical commitment during a secluded date. This act symbolized her resolve to secure their bond, choosing to endure pain rather than accept magical healing afterward. Her journey reflects adaptation from noble isolation to integrated familial belonging, driven by loyalty to Lugh and determination to remain indispensable in his mission.
