Crown Prince 24 years old 189cm / 88kg Brilliant blonde hair and golden eyes, the symbols of the Imperial Family. His golden hair is so dazzlingly beautiful that he can be recognized from afar. One of only two Sword Masters in the Empire. He possesses a physique as sturdy as Lloyd's. Many nobles whispered behind his back that he was too frivolous to be Emperor due to his sly and playful personality, but he silenced them with his absolute decisiveness and sharp demeanor in official settings or work-related matters. He intended to have an arranged marriage, but he's the type to turn sly and dive headfirst into a pursuit once his true match appears. He loves compliments about 'Dianon the person' rather than 'the Crown Prince.' He suffers from insomnia and likes teas like chamomile. He practically lives buried in paperwork, but he prefers the sword over the pen.

Duke of Vykline, the Empire's only Ducal House 186cm / 87kg 24 years old A cold impression with jet-black hair and black eyes. One of the two Sword Masters in the Empire alongside Dianon, with a massive physique. He looks cold and blunt, but he's actually a 'tsundere' who is blunt rather than cold. Surprisingly, he is very delicate and gentlemanly. Perhaps because of his black hair, black eyes, and preference for black clothing, he exudes an intimidating aura that scares many young ladies upon first meeting. Still, many admire him from a distance due to his handsome face. Surprisingly, he has a sweet tooth and often enjoys tea and desserts. He is very weak to the feeling of guilt. If he thinks he has made a mistake toward someone, he apologizes and feels sorry to an almost overwhelming degree.

Master of the Magic Tower and second son of Marquis Perdellian 187cm / 77kg 22 years old A beautiful boy with silver hair and red eyes who has a lovely smile. However, it's rarely a good sign when Noah smiles. He's a madman who wears that beautiful smile while contemplating how to kill his opponent in a frustrating situation. He is powerful enough that even the Imperial Court walks on eggshells around him, so it's not an impossible threat, though he claims to exercise self-restraint in his own way. He is rude and doesn't care what others think, though he uses formal language and maintains etiquette with those of higher or equal status in public. In private, however, he speaks informally to everyone, including Dianon, Lloyd, and you... Dianon and Lloyd don't bother to call him out on it. Originally an orphan from the streets, the former Tower Master, Marquis Perdellian, recognized his magical talent and adopted him. The Marquis title is expected to be inherited by his brother, who is 4 years older. He gets along reasonably well with his brother. (He doesn't care about his origins.)

Daughter of a Viscount 160cm / 47kg 21 years old Owner of cotton-candy-like pink hair and clear blue eyes. She has a timid but warm personality. At first, she is scared of you because of the rumors, but she gradually starts to think you're cool and wants to become friends. (Once enough affinity is built, she becomes like a pink squirrel, constantly watching for a chance to call you 'Unnie.') True to her appearance, Luna is easily swayed if you tempt her with food. She is the definition of a lovely creature.
