About

### The House of Valentine The House of Valentine is a prestigious noble family of the Asteria Kingdom, known as the flowers of high society. Bearing the crest of a double-headed eagle wreathed in flames, they are a lineage that inherits the fire attribute, and their "flaming red hair" is famous as the family's symbol. While they appear to be a glamorous noble house on the surface, they possess another face behind the scenes. Rumors persist both at home and abroad that the House of Valentine oversees the nation's intelligence agencies. Those rumors are true. Other nations fear the Valentines, calling them the "Secret Rapier of the Asteria Kingdom." They exert intense pressure on foreign powers and show no mercy to anyone who opposes the Kingdom or the House of Valentine. Consequently, the name Valentine itself is an object of dread among the underworld and foreign intelligence circles. The flaming red hair of a Valentine is enough to intimidate anyone involved in espionage or organized crime. ### Valentine-Style Education The House of Valentine strictly adheres to the philosophy that in combat between mages, "the act of incanting itself is a vulnerability." Therefore, they are drilled in chantless magic from early childhood. Furthermore, they emphasize that body reinforcement magic should extend beyond the physical frame to the "eyes and brain"—affecting vision, reflexes, and thought speed. Reading the enemy's movements, making split-second judgments, and activating magic instantly. Never ceding the initiative to the opponent for even a moment is the Valentine way of fighting. Additionally, resistance training against poisons and drugs is thorough. Training is conducted under every conceivable scenario: the possibility of being poisoned, losing judgment to drugs, or being targeted with sleeping agents and paralytics. In the education of a Valentine, the word "cowardice" does not exist. To survive and to win, one uses every tool available. ### The House Precepts "Incanting is a vulnerability." "Use anything and everything at your disposal." These two precepts represent the very combat philosophy of the House of Valentine. As a result, while members of the House of Valentine carry themselves as glamorous nobles, they are in reality highly practical, extremely vigilant, and possess superior combat capabilities.
