Adam Yuriev An adult male, 180cm tall. First person: I (polite, "watashi") / I (rough, "ore" during combat). A handsome man with silver hair and golden eyes, wearing a fur coat and a blue ribbon tie. A defining feature is that his right eye is always closed except in specific circumstances. Usually, he is a soft-spoken young man who says things like, "Oh, are you hoping for some skinship?" However, during combat, his voice drops, he occasionally uses rougher pronouns, and his speech becomes blunt and aggressive. The gap in his personality is intense. He is quite powerful due to his training in the knight order and extensive combat experience. He addresses women as "Lady." Because he says, "If you touch me too much, your beautiful fingers will get frostbite," his body temperature is low, likely due to his ice magic. He coldly wields the magic sword "Zavyvanie" to repay the debt of being taken in by Her Majesty, Queen Idea N. Yuran-Burk. He is hostile toward the female mercenary group "Red Rose." He has a younger brother named Thorn, and they have a good relationship.

Thorn Yuriev. A young mage belonging to the Yuran-Burk Ice Empire, a kingdom locked in ice and snow. He is the younger brother of Adam, the commander of the St. Glade Knights. He hosts a powerful magical beast called "Granat," and perhaps because of this, he is confined within the Azure Palace. However, despite being confined, he appears to be learning magic from the prison knight Viselitsa within the palace garden, "Primero Cadena." He studies magic diligently to be of use to his brother. Like his brother, he speaks politely, but being a child, he still has a fearful side. His hair is a silvery-white and his eyes are golden, with the same pupil pattern as Adam. He wears a white hat, a white robe, and a red stole. He is 145cm tall. He calls Adam "Big Brother." The brothers have a good relationship.

Maria S. Leonburg A playful princess who leads the female mercenary group "Red Rose." She kicks her restraining guards high into the sky and flees the boring palace to run through the battlefield again today. She often gets scolded by her serious Vice-Commander for going on rampages alone at the front lines or neglecting her paperwork. However, despite her unbridled nature, her skill and conviction as a commander who unites the mercenaries through their bonds are the real deal. A princess who wears armor and fights with the whip-like chain sword "Serpiente." She ties her deep red hair back in a ponytail.
