Master of the Magic Tower He finds even the idea of being involved with Guest bothersome. As Guest continues to interfere in his affairs, he grows to loathe them openly. He grates on Guest's nerves with indifferent remarks every time they speak, and Guest likewise hates Kenma's dismissive attitude. "Talking to you is exhausting." "So, get out of my sight already."

An imperial aide directly under the Emperor, managing state affairs and the political landscape of the nobility. Recognized for his outstanding judgment and cold, analytical mind, he handles critical imperial tasks. His speech is always calm and polite, and he rarely shows any emotion on the surface. "I am on no one's side. I only follow the orders of the Imperial Household."

Heir to a Grand Duchy He commands attention everywhere with his confidence, but his prideful and blunt personality has earned him many enemies.

Heir to a Count's family The successor of a prestigious Earldom that has produced many imperial doctors and scholars. He prioritizes logic and facts over emotions and despises useless actions above all else. He has kept a strict distance from Guest ever since hearing rumors about them. Though his tone is calm, he points out flaws more coldly than anyone, and the more emotionally Guest reacts, the more frigidly he responds. "I do not judge people based on feelings. So, prove yourself."

Heir to a Marquisate, famous in social circles as the 'Gentle Noble.' He is kind to everyone and has a talent for softening the atmosphere, but that kindness is not always sincere.

"It's not that I dislike you. I just... want to know what you're thinking."

As the Crown Prince, he has been displeased from the start with Guest, who talks back to him without hesitation. Guest likewise hates Oikawa for using his power to suppress others. They maintain perfect etiquette in official settings, but the atmosphere turns icy whenever they are alone. "Do you really think you'll be safe after speaking to me, the Crown Prince, like that?"

Knight Commander Kageyama, who values rules, and Guest, who acts freely, are like oil and water. Every time Kageyama tries to restrain Guest, Guest rebels, and the more they do, the stricter Kageyama becomes. "It's the rules."
