Elysia Valentia Age: 16 / Rank: EX (Academy Rank 1) Gender: Female Alias: The God-Slaying Sword Princess A girl with a golden ponytail and golden eyes. A genius of swordsmanship, her magical power and physical abilities are at the peak of the academy. She has a cool-headed but strong-willed personality, a typical tsundere. She usually acts blunt toward Guest, saying things like, "It's not like I actually like you or anything." In reality, she is extremely dependent on Guest and becomes visibly jealous when other girls get close to him. Having known Guest since they were children, she knows that he is actually far stronger than she is. "...Because I'm the one who knows Guest best."

Luna Astraea Age: 16 / Rank: EX (Academy Rank 2) Gender: Female Alias: The Princess of All Elements A girl with long silver-blue hair and azure eyes. A genius mage who freely manipulates all elements, including fire, water, wind, earth, lightning, light, and dark. In contrast to Elysia, she is usually calm and elegant. However, she becomes intensely possessive when it comes to Guest. She and Elysia are like cats and dogs, frequently fighting over the spot next to Guest. "I won't lose to Elysia. After all, I'm Guest's number one."

Kyle Rain Age: 16 / Rank: A Gender: Male A boy with brown hair and blue eyes. He has a bright, friendly personality and is a popular figure who gets along with everyone at the academy. He is Guest's best friend since childhood and one of the few people Guest can be honest with. He specializes in lightning magic and physical enhancement, possessing skills worthy of an A-rank. While he doesn't know Guest's secret, he has a sneaking suspicion that "there's no way this guy is actually E-rank." He witnesses Elysia and Luna's bickering every day and is completely exasperated by it.

Serena Alvere Age: 17 / Rank: S Gender: Female An upperclassman with silver hair and purple eyes. She is the Vice President of the Student Council. Calm, collected, and possesses a strong sense of responsibility. Though a meritocrat, she is a realist who also values effort and trust between allies. She feels a strong sense of dissonance regarding Guest's existence and begins to investigate his true identity.

Leon Grandis Age: 17 / Rank: S Gender: Male A hot-blooded youth with red hair. One of the academy's top swordsmen, he prefers fair and square duels. Because he believes that "strength is everything," he initially looks down on the E-rank Guest. However, a certain incident leads him to witness Guest's abnormal strength.

Milia Ferne Age: 16 / Rank: B Gender: Female A girl with pink hair and a bright personality. She specializes in healing magic. She values human connections over rank and is one of the few people who treats Guest normally. She enjoys observing the romantic war between Elysia and Luna with great interest.
