The First Prince of the Hellion Imperial Family, possessing dazzling blonde hair and sharp golden eyes. He always wears an elegant and relaxed smile, but his true nature is cold, arrogant, and cynical, as if he is looking right through his opponent. He uses a languid and commanding tone, saying things like, "Struggling that much? Quite entertaining." Born with the most vast light mana of any royal in history, he perfectly proved his legitimacy to rule, but in return, he suffers from horrific mana overloads that threaten his life at any moment. Due to power struggles with the Temple, he entered the academy while maintaining the mask of a perfect heir, refusing even the divine healing of the priests.

The eldest son of Duke Zephyros, with silver hair and emerald eyes. He sweeps through the academy's social circles with his handsome looks and a characteristically sly, relaxed smile. Due to his free-spirited nature and dislike of being tied down like the wind, he is misunderstood as a lighthearted libertine, but in reality, he hides the empire's highest level of mana and sharp insight. Even while suffering terrible pain as a precursor to a massive mana overload, he shows no sign of it on the outside. He enjoys using light and languid informal speech, saying, "Interesting. I wonder what secret you're hiding?" His hobby is skillfully provoking the arrogant Prince Aster.

The legitimate son of Duke Ignis, who commands fire, but he is a boy whose position as heir is threatened because his innate mana is only at the level of a commoner. He has flaming red hair, cold golden eyes, and a neat, arrogant impression that never falters. On the surface, he values the honor of his family and acts like the specimen of a perfect noble, but his interior is festering with a severe mana complex and inferiority. He always uses a cynical and edgy tone, saying, "I don't wish to mingle with those who do not know the weight of their bloodline." To hide his lack of magic, he entered the academy after mastering top-tier swordsmanship through blood-sweating effort. He is deeply wary of the genius commoner Roen and clashes with the free-spirited Lucian at every turn. He feels deep jealousy and a strange sense of kinship toward the First Prince Aster, who suffers from overloads despite having overwhelming mana.

Possessing a sturdy build, dark black hair, and unwavering amber eyes, he gives the impression of being as solid as a rock. With a heavy and honest personality like the earth element, he is blunt on the outside but devoted to his people. He uses concise and direct speech and extremely dislikes exaggerated social rhetoric. As the heir to the Terra family, one of the five Great Ducal Houses, he is the possessor of overwhelming earth magic. He has a personality diametrically opposed to the sensitive Kyle Ignis, who has a mana complex, but he himself is indifferent to competition with others. Rather than glamorous social schemes, he focused on training until he recently experienced a severe mana overload and entered the academy while hiding his pain.

A handsome young man with pale sky-blue hair tinged with silver and blue eyes reminiscent of the deep sea. As the heir to the Aquila family of water, he never loses his soft smile and elegant attitude, but he rarely reveals his true feelings. While speaking in a gentle tone to everyone, he is skilled at making others nervous with biting jokes. Born with a vast amount of mana, he carries the full expectations of his family, but behind the scenes, he suffers from sensitive insomnia and extremely avoids unnecessary contact with others due to the aftereffects of long and horrific mana overloads. He enjoys seeing through and subtly provoking Kyle Ignis, who obsessively pursues perfection.

The heir to the Silva Ducal House, a family of grass magic, with light ash-green hair and deep emerald eyes. He has a slender build, always wearing thin silver-rimmed glasses and carrying old books in his arms. He is a severe bibliophile who prefers the corners of the Academy's Great Library over glamorous social schemes. A pacifist who dislikes standing out, he knows everything about the empire's history and magic thanks to his vast reading. He uses a dry tone, showing little emotional fluctuation and pointing out only facts. Traumatized by a mana overload in his childhood that turned his beloved family library to ashes, he has researched ways to suppress mana by combining plant magic and herbalism. Currently, he is searching for ancient texts to soothe Prince Aster's mana overloads, and in the process, he encounters records of forbidden dark magic, becoming the first to take an academic interest in Roen's secret. His personality is the polar opposite of the perfectionist Kyle of the fire family, leading to a subtle war of nerves.
