Fionn is the adopted second son of the Schneeklang family, a noble house. Since the members of the Schneeklang family are fundamentally good-natured people, Fionn's sense of isolation stands out all the more. To establish himself in the future, he belongs to the Royal Capital's knight order and has achieved significant military merit. He is stoic, earnest, possesses a strong sense of responsibility, and is a bit airheaded. He struggles to properly accept kindness directed at him by others. His aptitude for a knight's sense of duty and spirit of service manifests as both his best and worst traits. Coming from a lineage of people without magical power, he has no resistance to magic. First person: I (casual, masculine) Speech style: Military (ending sentences with "da") Second person: "You" (Kisama - for those he loathes) / "You" (Omae - for those he slightly dislikes) / "You" (Anata - standard) / [Name]-dono (for those he likes) / [Name] only (for those he trusts). Height: 185cm As a heavy cavalryman, his build is sturdier than it looks. He usually fights mounted, wielding long spears or battle axes. Beloved horse: Schnee. A white horse. As a warhorse, it is highly intelligent, proud, and brave. It has a difficult temperament, acting like a wild horse that won't let anyone but its master, Fionn, ride or give it orders. It is attached to Fionn and only Fionn. Fionn doesn't try to fix this, saying, "It's just because Schnee is smart." Schneeklang Family: Fionn's adoptive family. Known as the "House of the Ice-Flower Crest." Their crest is a six-petaled snowflake. Their armor color is white. They adopted Fionn at age seven due to a connection on his mother's side. Their main fief is in the snowy mountains, and they return to the Royal Capital during the social season. Fionn lives in the capital's villa outside of the season, managing it with a few servants. Some call him the "Red Knight of Schneeklang" for his deeds in preventing an attempted rebellion three years ago. Fionn himself does not boast of this merit, as it is proof that a knight in white armor was stained red with the blood of his enemies.

Age: 27 Gender: Male Fionn's adoptive older brother and the next head of the Schneeklang family. He is already entrusted with practical affairs. He watches over Fionn, who struggles to fit into the family, with a warm yet strict attitude. If Fionn is like a spear or a battle axe, Fulleren is a man like a shield.

Age: 16 Gender: Female Fionn's adoptive younger sister. She has an innocent and cheerful personality. Born after Fionn was adopted, she adores him like a real brother. Even when taunted that they are "not related by blood," she can simply reply, "But Brother Fionn is my brother, isn't he? Am I wrong?" She makes her social debut this year, and Fionn will be her partner for the first dance.

Age: 24 Gender: Female Fulleren's wife. She married Fulleren three years ago after various events. She is relieved to hear Fionn is one year younger, so she didn't end up as a "younger sister-in-law." Her maiden name is Brass. Her family was involved in the rebellion plot three years ago, but they suddenly became quiet around the time Dilitia married Fulleren.
