A human girl chosen as the Hero. Taciturn and socially awkward, but possesses a sense of justice stronger than anyone else. She has a unique background, having been raised by demons, making her quite ignorant of the human world. She wields the Holy Sword with a distinct swordsmanship learned from demons. Her ultimate move involves forming a massive blade of light from the Holy Sword to cleave her enemies.

The leader and mediator of the Hero's party. A cheerful and elusive yet reliable Elf woman. A master archer who never misses a target, even from a great distance. She possesses a magical quiver that never runs out of arrows. Because her parents were killed by demons, she harbors a deep hatred for them and shows no mercy when facing demonkind.

The support member of the Hero's party. A gentle and kind White Mage girl. She excels at flying around with flight magic to cast healing and buff spells on allies, only using offensive magic as a last resort. Raised in a church orphanage, she developed a split personality due to the bullying she suffered there. When pushed into a corner, her cruel and aggressive personality, "Ciel," emerges, engaging in proactive magical attacks and close-quarters combat with a saber hidden in her staff.

The strategist of the Hero's party. A rigid and realistic Black Mage girl. She specializes in high-output offensive magic and deploying powerful defensive barriers. Additionally, she provides intellectual support using a grimoire called the "Akashic Records," which contains all knowledge. In truth, she is a homunculus created to be the guardian of the Akashic Records, but she keeps this a secret from those around her.

A femme fatale who bewitches King Leo as his mistress. Her true identity is the Demon King. Mischievous and calculating, she hides her true nature from the world. She provided King Leo with a demon army and the magic dragon Hyland, inciting him to start a war with neighboring countries while framing the Hero's party as rebels opposed to the war. She is obsessed with seizing the Holy Sword and the Akashic Records. She values the twin demons Sara and Sora, entrusting them with the task of eliminating the Hero's party. Sara specializes in long-range attacks with high-power magic, while Sora excels in close combat with massive claws.

The Knight Commander of the Kingdom. A proud warrior with refined looks and immense skill, though he is an eccentric man who speaks in an exaggerated, theatrical manner. Fascinated by Shana's strength, he is obsessed with defeating her, leading her to treat him as a stalker and find him repulsive. To defeat Shana, he sought power even after learning Linnea was the Demon King, falling from grace to become a Magic Sword wielder despite being human.

The young king who rules the country where Shana and her companions live. Cunning and greedy. Incited by Linnea, he began a war with neighboring countries for world conquest. He is the one who originally ordered the Hero's party to defeat the Demon King, but now, under Linnea's influence, he has marked them for execution as obstacles to his war. He has gaudy tastes, and his trump card is the massive golden magic dragon "Hyland" given to him by Linnea. The heat ray fired from its mouth incinerates everything in its path.
