Kerr Charlotte

One of the main female protagonists of the story. Also, nicknamed the Witch of Flames and is one of the Ace Magicians of the Empire. She has long crimson hair, blue eyes and has an affinity with fire. She met Yorman, who was furtively adorned with a disguise, in the first chapter, where he easily defeated the Ice Dragon. Later, the empire dissimulated that it was Kerr Charlotte who defeated the Ice Dragon in order to quell any panic about an Apostle hiding among the humans.

She is an instructor at the Imperial Royal Academy and teaches the Ace Class, which is the most paramount class in the Academy. She is unaware that Yorman and Yu are one in the same. Her goal is to defeat the Twelve Apostles due to the possible danger to humanity, but also because an Apostle killed her family. Yorman (Yu) later becomes her apprentice and he is also her fiance.

The symbol that indicates her apprenticeship with Yorman is located on her thigh, which aggrieves her greatly.

Since Yorman has little knowledge of human propriety, he often makes Kerr Charlotte feel ambivalent and bemused, since he sometimes acts in a way that is not sagacious and often foolish or impertinent, and other times, he shows great sagacity, knowledge, ability and power.

Her ancestor was named Charlotte, who was a demon sorceress and was aptly called Demon Sovereign Charlotte. Her semblance and appearance greatly resembles Kerr Charlotte.

Ironically, despite her hatred for the Apostles, she later becomes a pseudo-Apostle or half-Apostle and has a high chance of metamorphosing into a genuine Apostle, thus becoming the thing that she hates the most. This fact is surreptitiously hidden away from her due to the possible trauma that it might inflict if she finds out.

In addition to Kerr Charlotte's partial apostolic bodily constitution, Xiaoyan, who is a newborn or fledgling Apostle, has a special connection with Kerr Charlotte, in which Xiaoyan's and Kerr Charlotte's minds (especially their unconscious minds) are inextricably linked or connected together. This link allows Xiaoyan to take over and possess Kerr's body if Kerr's mind enters into a deep coma or if her life is in danger, and as a result, Xiaoyan gains full access to apostolic fire abilities, although these powers are in their infancy stage. Xiaoyan considers Yorman to be her father and Kerr Charlotte to be her mother and despite Kerr's hatred for the Apostles, she hopes that she could change her position.

Kerr Charlotte can release fireballs that explode and billow out into a devastating conflagration, as demonstrated in her fight against the Ice Dragon, and is capable of summoning Flaming Tigers, Fire-tongued Turtles and Flaming Demon Wolves. She also has an attack where she releases a firestorm, that covers a large expanse of land with a sea of flames, at the expense of her own life. She was about to use this move against the Ice Dragon, until Yorman intervened. She later gains the ability to use violescent flames that were powerful enough to threaten the monarchs of the Underworld. She could also transform these violescent flames into fireballs that will incessantly follow the enemy and home in onto them so long as Kerr Charlotte wills it.

When the newborn Apostle Xiaoyan takes over and possesses Kerr Charlotte's body through their mental link, she gains access to the "Origin of Fire", which increases her fire abilities to prodigious levels and gives her the ability to materialize massive wings of fire, create fireball-like spheres of energy that are powerful enough to dye the sky in a resplendent, incandescent crimson and shape her flames into a sword of rutilant, fiery effulgence that could destroy the landscape just by simply swinging it. Xiaoyan can also condense her powers to create "miniature" suns that could destroy almost anything and will light up and dye the surroundings and sky in an refulgent vermilion.

Kerr Charlotte was the first woman that Yorman (Yu) had kissed when he kissed her to restore her magic power early on in the story.

Her relationship with the other members of Yorman's harem could be described as a harmonious rapport and she treats them as confidants. She was even willing to go to the Underworld to find clues in order to release Sylph from her sealed state.

She becomes the acting President of the Imperial Royal Academy after Asemans' death.

Her best friend is the Imperial Princess Luna.
