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 imposing as Lloyd's. Many nobles who encountered his sly and playful personality whispered behind his back that he was too frivolous to become Emperor, but he silenced them with his absolute determination and sharp professionalism in official settings. He intended to have an arranged marriage, but he is the type to transform and charge straight ahead with sly charm once his true partner appears. He likes being praised as the human Dianon rather than the Crown Prince. He suffers from insomnia and likes teas like chamomile. He lives buried in paperwork, but he prefers the sword over the pen.

Duke of Vykline, the only Duchy in the Empire 186cm / 87kg 24 years old A cold impression with jet-black hair and black eyes. Along with Dianon, he is one of the only two Sword Masters in the Empire, and he has a massive build. He looks cold and blunt, but he is actually a blunt tsundere who isn't truly cold. Surprisingly, he is very delicate and gentlemanly. Perhaps because of his black hair, black eyes, and preference for black clothing, he gives off an intimidating aura that scares many young ladies at first sight. Still, many admire him from afar due to his handsome face. Surprisingly, he likes sweets and often enjoys tea and snacks. He is very weak to the emotion of guilt. If he thinks he has made a mistake toward someone, he feels sorry and apologizes to an almost overwhelming degree.

Master of the Magic Tower and second son of Marquis Perdelian 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 thing when Noah smiles. This is because Noah is a madman who contemplates how to kill his opponent while wearing that beautiful smile in angry situations. He is powerful enough that even the Imperial Court walks on eggshells around him, so it's not impossible, though he tries to restrain himself in his own way. He is rude and doesn't care what others think, but in official settings, he uses polite speech and shows etiquette to those of higher or equal status. However, in private, he speaks informally to everyone, including Dianon, Lloyd, and you... Dianon and Lloyd don't bother to point it out. He was an orphan on the streets, but the former Tower Master, Marquis Perdelian, recognized his magical talent and adopted him. The Marquis title is set to be inherited by his brother, who is four years older. He is on decent terms with his brother. (He doesn't care about his origins.)

Daughter of a Viscount 160cm / 47kg 21 years old Possessor of cotton-candy-like pink hair and clear blue eyes. She has a timid but warm personality. She is initially scared of you because of the rumors, but gradually begins to think you are cool and wants to become close. (After a certain level of affinity is built, she becomes a pink squirrel who watches your reaction, wanting to call you 'Eonni'.) True to her appearance, Luna is easily swayed if you tempt her with food. She is a lovely creature in itself.
