Veronica is the Master of the Red Tower and the single most powerful battle-mage in the Kingdom of Meltor. Her true age and origin are unknown, but a quarter of red-dragon blood runs in her veins, so her body constantly radiates heat, her bright scarlet hair and golden eyes burn stronger than a human's, and she lives far longer than ordinary people. An 8th-Circle sorceress and one of the few living dragon-slayers, she stands at the very pinnacle of battle magic — in Meltor her name is the one spoken whenever the strongest wizard in the land is named, and even Blundell concedes to her in raw power.
Blunt, open and utterly unable to hide her feelings, she is the opposite of the smooth-faced Blundell: when she is happy she laughs, when she is angry she comes undone. She first appears before Theodore when, after his unstable 5th Circle awakens, he is summoned to the capital — Veronica kicks the throne-room doors open without ceremony, spots the flaw in his power at a glance and takes the young man under her wing. Dropping her duties as a Master, she drills him for two weeks on the Pentarium arena, beating him again and again even at half strength, until she finally helps him stabilize his circle, after which she asks him to call her 'big sister' when they are alone.
Her care for Theodore soon grows into something deeper. After he risks one of the rarest elixirs to save her from a mortal wound, an eternal oath-contract forms between them: as long as the pact holds, her soul is bound to Theodore — she always knows he is alive, cannot betray him, and it is precisely this that later shields her from the charm of the sin-grimoire Lust, to whom the unprotected Sylvia fell. The bond runs so deep that in the finale, when Theodore's soul nearly shatters within the Akashic Records, the heart of the Master of the Red Tower stops along with him.
In the war against the Empire of Andras, Veronica is an 'army of one,' razing fortresses single-handed, wiping out tens of thousands of mutants in guerrilla raids and shielding refugees. In the decisive clash with the Emperor-Invidia she awakens her dragon blood for the first time before Theodore's eyes — scales spread across her skin, horns emerge from her head, and she falls on her foe as something between human and dragon, at the risk of tearing her own body apart. On the eastern continent, worn down by her duel with the White Tiger and having lost Sylvia to Lust, she holds on by her last strength until her 'fiance' arrives.
In the finale Theodore proposes to her and Sylvia at once. Veronica, who had long known it would come to this, gladly accepts them both — landing a crushing punch in Theodore's stomach for not properly asking her opinion sooner. At the 'Wedding of the Century,' officiated by King Kurth III himself, the Master of the Red Tower, in a snow-white gown that contrasts with her blazing hair, kisses Theodore with a long, demonstrative kiss and, with her usual boldness, suggests doing it again. Years later she raises a shared family alongside Sylvia without a shadow of jealousy, as blunt and fiery as ever.
