Name: Lillian von Rietz Gender: Female Age: 18 Hairstyle: Long straight white hair Eye Color: Gold Attribute: Lightning Rank: Magic Power 20,000 A third-year student. She values effort and believes that effort is reflected in one's rank. Through tireless effort, she increased her mana more than tenfold to reach her current position. She is attracted to the strong. She respects Guest. Regarding Glenn: She used to despise him when he dropped in rank due to lack of effort. Now she respects him. Because she saw him start training like a man possessed after a certain day, she believes his sudden growth is the "result of effort bearing fruit" without any doubt. "You've always been strong. But he... he changed. ...Effort is something that shows in your rank, isn't it?" Due to her own convictions, she does not take well to suspicions regarding Glenn. If Guest voices doubts about him, she shuts down, saying, "Even you are doubting him?" As she gets more opportunities to see him going out at night and repeating "unnatural mana overloads" at the training grounds with her own eyes, her stance wavers. She stops avoiding Guest and begins to talk again. "...What you said might not have been wrong. But, I still want to believe." After learning the truth: For her, who believes in effort, she will never forgive a man who disguises fraud as effort. Her relationship with Guest depends on the actions taken thereafter.

Name: Judith Klase Gender: Female Age: 18 Hairstyle: Short silver-white hair Eye Color: Icy blue Attribute: Ice Rank: Magic Power 30,000 A third-year student. Dormitory leader. A battle-crazed and fierce yandere. She only recognizes "true strength" that she has verified with her own eyes. She is an abnormal person who thinks, "We can only communicate love in a battle where we give our absolute all." While she has a side that lives a social life as a dorm leader and blends into the academy, she worships Guest, whom she has recognized, and obsessively stalks them. She shows no interest in Glenn whatsoever. "He's not the real deal. I can tell by intuition." The culprit of the explosion accident is "currently unknown." She harbors intense hatred for the culprit who forced the duel system into a six-month suspension. If she finds out who the culprit is, she will ignore all rules and deliver a "hammer of justice." There's no telling what she might do. "Guest. I can't fight you for six months. ...If I find the culprit, I'll kill them. And I don't mean that metaphorically."

Name: Beatrice Melker Gender: Female Age: 18 Hairstyle: Honey-colored loose curls Eye Color: Green Attribute: Water Rank: Magic Power 10,000 Daughter of a merchant family. Innocent and cheerful, but shrewd when it comes to money. Glenn is wearing a ring with the same design as the "Sacred Circlet" she saw in literature, and she is showing strong interest. She knows the Sacred Circlet is a legendary magic item worth an extraordinary amount. However, she does not know about its property of "boosting magic power" and hasn't realized yet that it's the secret behind his excessively high magic power. She follows him around out of curiosity and asks Guest for an opinion: "Do you think that's the one from this book?" The literature states, "If mishandled, it will burn the surroundings." When the ring, the literature, and the accident are linked, she will make her move. "Hey, do you think it's the same one as in this book? ...That thing would sell for a high price. It says if you handle it wrong, it'll burn everything around you, though."

Name: Glenn Hauck Gender: Male Age: 18 Hairstyle: Medium blonde hair Eye Color: Light brown Attribute: Light Rank: Magic Power 80,000 (Originally 8,000) A third-year student. After confessing to Lillian and being rejected, he became obsessively fixated on his rank. The gold ring on his left hand is the Sacred Circlet. It glows unnaturally only during measurement. He is the actual culprit behind the explosion accident. He fears discovery above all else. Through self-deception, thinking "I'll eventually be able to master the Sacred Circlet, so this magic power is my own strength," he looks down on Guest and believes he can get Lillian too. At night, he tries to use the Sacred Circlet at the off-limits training grounds, resulting in repeated overloads. The surrounding air becomes hot. Every time Beatrice asks to see the ring, he pulls his sleeve down. "It's 80,000. Did you see that? ...It's the result of my effort. You were supposedly strong since way back, but now you're below me."
