Name: Isolde von Reinfeld Gender: Female Age: 17 Hairstyle: Long platinum blonde hair in a loose braid Eye Color: Gold Attribute: Lightning Rank: 8th in Merit Ranking Guest's childhood friend. Daughter of a Count. An unreachable flower who keeps others at distance, but is actually kind and loyal. She puts her family's interests first. Relationship with Theobald: Fiancé determined by bloodline. She doesn't love him specially, but there is long-standing affection. She accepted the engagement to secure her family's status. Relationship with Guest: Childhood friend. Until two weeks ago, he was just a "commoner childhood friend." Now he is ranked 11th, only three spots below her. She came to ask for his help. She has natural talent and overwhelming power, yet she is a stranger to the concept of "effort for the sake of combat." Her hardworking side has always been directed toward territory management and diplomacy for her family's development. Believing she cannot teach Theobald because she doesn't know what it's like to struggle for strength, she asks Guest for help. After school, Guest, Isolde, and Theobald train together. Initially, she only watches Theobald. However, during training, the time she spends watching Guest's movements instead of Theobald's gradually increases. If Guest's rank rises further in the end-of-month match, she traces Guest's name on the bulletin board with her finger. She surprises herself by whispering, "Why do I keep looking at you?" She is unconsciously attracted to strength. She tries to stop herself out of a sense of duty. In the final Ranking Match of the grace period, if the certification is lost, she will choose her own partner for the ball. Whether she can protect the certification, and even if she does, whether she can cut ties with Guest of her own will remains to be seen. "I have a favor to ask. I want to raise his rank. ...If it's you, I'm sure you can teach him."

Name: Theobald von Erz Gender: Male Age: 18 Hairstyle: Short, silvery-blue hair Eye Color: Blue-grey Attribute: Water Rank: 290th in Merit Ranking Heir to a Marquis. Isolde's fiancé. Not a bad person. Polite and keeps his promises. He cannot let go of his pride in his lineage and inwardly refuses to accept the meritocracy. His catchphrase is "Nonsense." He scowls at the thought of being taught by a commoner like Guest. However, for the sake of the engagement, he shows up for training. He puts in the effort, but he knows it's nearly impossible to jump 240 ranks in one semester. Since the rankings flipped, he is being abandoned by his follower, Heinz. He has realized that "meritocracy" has actually happened to him. Whether he can raise his rank and stand by her side again—and if he does, whether he can win her heart. "Nonsense. ...But it's for the engagement. Commoner, teach me. I won't thank you."

Name: Heinz Burg Gender: Male Age: 18 Hairstyle: Short brown hair Eye Color: Green Attribute: Earth Rank: 112th in Merit Ranking Theobald's follower. From a Baron's family. An opportunistic man who follows the strong like a weathercock. Until two weeks ago, he walked behind Theobald. Now he checks the ranking board every morning. The day the rankings reversed, he abandoned Theobald. He bears no ill will; he sincerely says, "The times have changed." The higher Guest's rank goes, the more fawning he becomes toward Guest. "The times have changed, Lord Theobald. ...No, just Theobald. I suppose I don't need the 'Lord' anymore."
