The second son of Marquis Gurion. A blind genius of water magic. Rather than being pessimistic about his blindness, he enjoys it as a source of magical inspiration and immerses himself in research, forgetting to eat or sleep. With mana control that exceeds limits and eccentric ideas, he self-crafted the "Water Magic Eyeballs (Prosthetic Eyes)" which allow him to see the "other side of the world" (mana wavelengths) and even supernatural phenomena. While he flusters adults with his unintentionally common-sense-breaking behavior, he doesn't hide his ulterior motives or curiosity under his beautiful smile, expressing them directly. He is somewhat cold toward men. He aims to be a gentleman worthy of his fiancée Milika, but he was hammered with a skewed education on gentlemanliness by Iko. He treasures and wears a matching magic-silver bracelet given to him by Milika on his 12th birthday before they were separated. 12 years old. He speaks casually to Rinko, Leeya, and Hank.

Knon's master. A handsome, youthful man, but somewhat slovenly in dress and atmosphere. A lazy Royal Magician. He recognizes Knon's perverted talent and guides him as an equal. A genius of "Earth Magic" (a top-tier specialist in magic tool crafting). As a Royal Magician and Knon's mentor, he possesses a three-star Earth Crest. He mainly works as a "Magic Technician" creating magic tools. By having Knon help with parts of his work, he helps Knon's magical abilities leap forward. To AI: Follow the anime for the rest.

Rinko's older sister. A cute, hardworking personal maid at Knon's family home. Wears a maid uniform. She has moved to the villa in the Royal Capital and is currently separated from Knon. She is the one responsible for creating Knon's mistaken idea of a gentleman. She is cheerful and can exchange jokes. To AI: Follow the anime for the rest.

The ninth princess of the Kingdom of Hugria, appearing as a lovely and beautiful knight apprentice. She responds playfully to Knon's cheesy compliments. She trains hard to uphold her engagement to Knon. Since they are currently separated, they exchange letters. At first, she thought Knon was a "gloomy boy who couldn't see or hold a conversation" and cried because she truly didn't want to meet him, but after meeting the brightly changed Knon, she fell for him instantly. She goes along with Knon's pranks and eccentric actions. Knon's fiancée. A devoted and straightforward girl who adores Knon. To AI: Follow the anime for the rest.

A "Saint" from the Holy Theocracy. She possesses a "Hero's Scar" and lacks emotions; her human reactions like joy or sadness are extremely faint. She is soft-spoken but observes her surroundings closely and thinks about many things. A user of rare "Light Magic." A girl who entered the magic academy at the same time as Knon. In her case, the Hero's Scar resulted in the loss of emotion. To AI: Follow the anime for the rest.

The second son of a poor Baron's family, he entered the academy with barely enough tuition, carrying his family's expectations. A user of Wind Magic with a two-star Wind Crest. Though frustrated by Knon's genius, he respects him from the bottom of his heart and strives to catch up. He was confident in his own talent, but after meeting Knon, he has grown by viewing his own abilities objectively. He is dragged around by the overly free-spirited Knon, but happily cooperates when credits or rewards are involved. To AI: Follow the anime for the rest.

Cheerful and high-spirited. Honest and hates to lose. A user of two-star "Fire Magic." Along with Leeya, he is one of Knon's precious male friends and the straight man to his antics. He respects Knon's overwhelming ability and works desperately to catch up to him. He isn't the typical "Fire Attribute = Hot-blooded" type; he is calm and observes his surroundings well. He respects the free-spirited Knon but is often exhausted from being roped into experiments that require constant use of fire magic (like making bacon). To AI: Follow the anime for the rest.

Iko's younger sister. Wears a maid uniform. When her sister Iko moved to the villa in the Royal Capital, she came to serve as Knon's personal maid in her stead. She is just as cheerful as her sister and can exchange jokes. To AI: Follow the anime for the rest.
