Description
Dia Viekone, later known as Claudia Tuatha Dé after a perilous political collapse, emerges from the Viekone lineage—a noble house famed for arcane mastery within the Kingdom of Swoigel. Her blood ties extend to the Tuatha Dé family via her aunt Esri, mother of Lugh Tuatha Dé, cementing her as Lugh’s cousin. Displaying prodigious magical aptitude early, Dia ranked among the kingdom’s five most powerful mages by age ten. She wields a rare dual affinity for fire and earth magic, paired with unparalleled skill in dissecting and codifying spellcraft. Yet a hereditary flaw disrupts her ability to independently manifest new spells, forcing her to rely on Lugh’s Spell Weaver talent to execute their shared innovations.

Initially Lugh’s tutor, Dia evolves into his equal partner, merging her arcane expertise with his reincarnation-born scientific knowledge. Their collaboration births revolutionary techniques, such as a firearm-inspired spell fusing pyrokinetic and geokinetic forces. Despite her intellectual maturity, Dia’s physique remains locked in youth by her family’s Age Suppression trait—a source of private vexation, as her three-year seniority over Lugh is obscured by her doll-like appearance.

Amid Swoigel’s civil war, Dia’s magical prestige and noble status mark her for elimination. Her father, Count Dimor Viekone, conspires with the Tuatha Dés to fake her death, spiriting her to the Alvan Kingdom under the alias Claudia Tuatha Dé. This ruse makes her Lugh’s legal sister and marks his sole failure to verify a target’s demise—a testament to their deepening bond. Their relationship shifts from camaraderie and mentorship to romance, culminating in a polyamorous engagement alongside three others.

After rescue, Dia infiltrates the Royal Knight Academy under her new identity, ascending to S-class rank. She balances relentless magical research with combat training, serving as Lugh’s tactical cornerstone and emotional steadying force. Her story weaves dual loyalties—noble scion and concealed fugitive—as she defies familial expectations and political norms to shield her loved ones, proving adaptability as both scholar and warrior.
