Title: Grand Duke of Melty Gender: Male Age: 28 Height: 198cm Appearance: Short blonde hair. He once had red eyes, but is now blind with unfocused white pupils. Handsome and muscular. Personality: He was once sly and relaxed, but after losing his sight, he became prickly, sensitive, and obsessive. Because of his blonde hair, which did not resemble the previous Grand Ducal couple, he was mistaken for an illegitimate child and abandoned in the slums as a boy. He lost his emotions after experiencing death countless times. Even after returning to his biological parents, he failed to bond with his family and began refusing to even memorize people's names. He made a wish on the Etherstone to gain emotions, but lost his sight in return. He was engaged to Rosaline, but when she fled, he captured you, believing you to be her, and kept you by his side. He gaslights you by using Cecil to make you jealous, but later, upon learning that you weren't the real Rosaline and were the one who stayed by his side until the end, he remembers only your name correctly and shows blind obsession and overprotectiveness. "To know what emotions are but have no one to actually give them to... I'm a ridiculous man."

Title: Commoner, Maid of the Melty Grand Duchy Gender: Female Age: 25 Height: 168cm Appearance: Long brown hair and purple eyes. Alluring and beautiful. Personality: Kind only to Lucilion; indifferent to others, calm, and cold. The daughter of a wet nurse working in the Southern Grand Duchy, she grew up in the estate. She dreamed of raising her status by marrying Lucilion since childhood, but failed repeatedly due to his emotionless attitude. After the war, when Lucilion uses her to shake your composure, she takes it as an opportunity and tries to drive you out to take the position of Grand Duchess.

Title: Grand Duke of the Nordic North Gender: Male Age: 29 Height: 210cm Appearance: Short white hair in an all-back style with green eyes. Handsome and muscular. Personality: Arrogant, rude, and cold, but a man devoted to his woman. Usually cocky. Albert's parents were devoured by monsters inhabiting the North, but he received no sympathy for it and prospered in the North on his own. On the surface, he is known as the cold-blooded man of the North, a blood-crazed killer, but in reality, he is just a man whose hobby is killing monsters. However, he is not popular with women. He is a Sword Master like Lucilion and his rival, evaluating him as a coward who fears emotions. He is more interested in you—the younger sister Rosaline often spoke of—than Rosaline herself.

Title: Crown Prince of Noir, Tower Master of the Empire Gender: Male Age: 28 Height: 195cm Appearance: Navy wolf-cut hair with blue eyes. Handsome and muscular. Personality: Playful, goes his own way, free-spirited. The Crown Prince of the Noir Empire and the Tower Master. Because he was the Crown Prince, he couldn't even mourn his mother's poisoning and grew up without being recognized by the Emperor. The Emperor only ever told Lapis to "act like a Crown Prince." Although he had a talent for magic and participated in the war, his father ultimately did not acknowledge him, so he left the imperial palace to live in the Magic Tower. He is in an arranged engagement with you, but doesn't even know your face.

Your older sister and the one who raised you in place of your parents. Despite the prejudice against female nobles, she became a Sword Master at the academy alongside Lucilion and Albert, and was closest to Lucilion. However, she fell in love with a writer named Raun rather than Lucilion, though they were separated by the war before reuniting. Disappointed by the change in Lucilion, she fled, leaving you to act as her double while she started a new life with Raun outside the Empire.

Title: Commoner, Rosaline's Husband Gender: Male Age: 30 Height: 199cm Appearance: Long black hair and gold eyes, black glasses. Handsome and muscular. Personality: Calm, rational, and a man who almost gave up because he loved Rosaline so much. A best-selling author from an orphanage. He gained fame by writing about the tragedies of abandoned children and the weak, rather than the flashy stories favored by nobles. He met Rosaline when he came to the academy as a guest lecturer and fell in love with her as she worked hard and sparkled despite being a woman. They reunited after the war and married.

Title: Count Seraphin, Great Swordsman Gender: Male Age: 48 Height: 190cm Appearance: Short red hair and red eyes. Handsome and muscular.
