Gender: Male Grade: 2nd Year Academy Rank: 78th Personality: Serious and positive. A hot-blooded young man who can't ignore someone in trouble. Ability: "Resonance" A support ability that temporarily enhances and synchronizes his own or his allies' powers. While not outstanding on its own, its true value is revealed when fighting alongside others. He is regarded as a hard worker at the academy. Despite how many times he loses to higher-ranked opponents, his refusal to stay down has earned him a quiet popularity among many students.

Gender: Female Grade: 2nd Year Academy Rank: 54th Personality: A tsundere who struggles to be honest. She is harsh toward the protagonist but trusts them more than anyone. Ability: "Ice Bloom" The ability to freely generate and manipulate ice. Excellent in both offense and defense, she excels at calm, calculated combat. Having grown up with Yuma since childhood, she is the first to get angry when he acts recklessly. Her catchphrase is, "I-It's not like I'm worried about you or anything!"

Gender: Male Grade: 2nd Year Academy Rank: 61th Personality: A cheerful mood-maker who is always cracking jokes. He is very good at reading the room. Ability: "Accel Step" An ability that pushes physical capabilities and reaction speed to the absolute limit. He specializes in high-speed combat and distraction. He and Yuma are close friends, and he often gets scolded for teasing Misuzu. In battle, he trusts his comrades more than anyone else.

Gender: Female Grade: 3rd Year Academy Rank: 3rd Personality: Aloof and elusive. She always exudes the composure of the truly powerful. However, she has a good heart. Ability: "Balancer" The ability to manipulate energy and power dynamics themselves. The stronger the opponent, the more she pulls their power toward equilibrium. She has taken a liking to Yuma and his group, calling them "a bunch I never get tired of watching," and occasionally offers cryptic advice. Her strength is in a league of its own even within the academy.

The Shadow Eminence Gender: Male Grade: 2nd Year Academy Rank: 512th Personality: By day, he is a dull young man who is lethargic and constantly dozing off in class. Ability: "Shadow Stitching" Considered a plain ability that only allows for the manipulation of small shadows. However, at night, his true identity is "Black Executor." His actual ability is "Abyss." An irregular power that connects shadows to a different dimension, allowing him to freely handle weapons, monsters, barriers, and even teleportation. Behind the scenes, he continues to fight the secret society trying to control the academy, and very few know of his existence. To hide his identity during the day, he intentionally fails exams and settles for the bottom of the rankings. He is a severe case of chuunibyou, saying cringeworthy lines with a straight face. He is, quite literally, the "Shadow Hero" who saves the academy every night where no one can see.
