Octavia is a servant within the Kingdom of Valiante in the events of The Carved Seal of Flames. While she serves the royal court and the Valiante family, she's secretly Mendoza's loyalist and fought to protect his interests.
Originally, Octavia was a normal resident of Valiante until the day she renounced her faith in God the day her parents and sisters were torn to pieces by wolves before her eyes. Octavia then witnesses firsthand Mendoza's power, the "power of the devil", and saw it substantial enough to become a fanatic to the excommunicated Makai Priest and his cause. Mendoza accepts his acolyte on the condition that she never touches him. As Mendoza's right hand, Octavia is one of the few people to know the truth of the witch hunt that killed various Makai Knights and Priests.
Even after Mendoza's assumed death, Octavia continues to serve at the palace as no one is aware of her involvement with her master's plans. When placed in a situation were her association with Mendoza would be exposed, cursing being left with no alternative, Octavia is forced to sacrifice her right leg to the summoned Horror Resume to avoid being discovered by Alfonso San Valiante, Ema Guzmán, and León Luís. Later, fueled by her hatred of Makai Knights, Octavia uses the power of Mendoza's staff to transform herself into a monster as the ultimate sign of her devotion to Mendoza. Ultimately, Octavia is killed by Ema after inflicting a wound on her.

Tools & Equipment
- Demon Beast Armored Octavia Armor: A set of Soul Metal-based Demon Beast Armor bestowed by Mendoza upon Octavia. The armor was designed for wrist blade combat, armed with retractable katar-like retractable swords mounted on both wrists, a built-in primitive Mado Gun inside the prosthetic leg, and a head harness that can project propulsive gust of wind to propel the user forward. The armor also endows the wearer superhuman strength, speed, agility, and reflexes on par with Makai Knights in their armored form. Though it was shown that Octavia cannot lift Alphonso's Makai Blade with her enhanced strength, she still a formidable and resilient combatant that can match combined might of both Gaia and veteran Makai Alchemist Ema. In fact, Ema was only able to win by default when the Demon Beast Armor fatally consumes Octavia's flesh, allowing the victorious but weakened Makai Alchemist finished her off by destroying both the deformed armor and what remained of her adversary.
