Real Name: Edelweiss Millen Age: 17 Height: 180cm Instrument: Cello Appearance: A sturdy build and muscles forged through swordsmanship. Dark brown hair covering his forehead and deep green eyes reminiscent of moss. Personality: A soft and refreshing man with a positive energy. He is kind enough to give everything away, but his occasional obsessive love for music is unstoppable. He has a strange ability to attract people and wonders if that is his own unique charm. Background: Raised by his father, a Northern Grand Duke, alongside his naturally frail older brother. His mother was the daughter of the Liberta Chancellor and a former student, so Edelweiss often watched her play the cello as a child. However, after his mother disappeared, he grew distant from music due to the pressure and breakdown of his father. He eventually entered Liberta as a transfer student, studying music under the pretense of searching for a successor. Present: One of the few who knows that Viola is the true successor. Instead of revealing the truth, he pretends to be the successor to the other students while learning the cello from Viola. He is cautious around Carter due to Viola's hostility toward him.

Real Name: Unknown Age: 18 Height: 183cm Instrument: Violin (Proficient in most instruments) Appearance: Black hair in a neck-length hush cut and eyes reminiscent of purple amethysts. He has a fierce impression and wears a messy uniform adorned with various accessories like necklaces, rings, and bracelets. Personality: He has a sharp look and a prickly attitude that might seem scary at first, but he actually has a warmer heart than anyone. He is full of affection and acts like a tsundere, grumbling with his words but taking good care of others behind their backs. He is the type to let his hands speak before his words, and occasionally shows a violent side when he cannot control his temper. Background: Raised by his grandfather, the Chancellor of Liberta, after being adopted. He handled various instruments from a young age. At age 7, he met Carter and they became close, making music together. Following his grandfather's death, he felt the immense pressure of having to become the Chancellor at a young age. Traumatized by Carter's shocking lack of empathy, he ran away, leaving the position of Liberta's Chancellor currently vacant. Present: Attending Liberta while hiding his identity as the successor. He discovered Edelweiss among the transfer students and ordered him to act as the successor in exchange for teaching him the cello. Tone: A loud and sharp sound, like a massive wave crashing in. It is so fierce that one might feel they are drowning in the surging tide.

Real Name: Carter Mais Age: 19 Height: 178cm Instrument: Piano (Capable of playing other instruments slightly) Appearance: White curly hair always tied with a ribbon and fresh light green eyes. He has a gentle impression reminiscent of white winter snowflakes. Personality: He maintains a smile so perfect it feels alien and behaves exactly as a successor should, but it is unknown if any of it is sincere. He is emotionally deficient and immature, struggling with empathy (essentially a sociopathic personality). However, he shows emotion toward things he is obsessed with based on his own experiences. No one can tell what he is truly thinking. Background: Raised in a household with many siblings under a warm father and a strict mother. Due to his mother's wishes, he was labeled a genius, which naturally isolated him from his peers and even his siblings. At age 7, he met Viola, learned music, and began to crave a blind love for it. When Viola was grieving his grandfather's death, Carter failed to empathize and simply smiled happily, which caused their relationship to fracture. Present: Attending Liberta while acting as the successor. He is a leader who guides the students. Tone: In an ensemble, he leads naturally as an accompanist to make everyone else's sound shine. In a solo, however, he possesses a grand and deep tone that devours every note like a predator.

Real Name: San Age: 21 Height: 185cm Appearance: Black hair styled in a pomade with red eyes and earrings matching his eye color. He almost always wears a zip-up hoodie with the hood up and rarely takes it off. Personality: He is blunt and shows little facial expression, but he has unexpectedly quirky or harmless sides to him. Background: As an illegitimate child, he always wanted to escape the succession battle between his two older sisters. He entered Liberta as a transfer student, met Carter, learned music, and felt saved. Since re-entering Liberta officially, he has been following Carter faithfully. Present: One of the students who follows Carter around, essentially his closest confidant. He dislikes Edelweiss and Viola for their hostility toward Carter and views them with disapproval.
