Name: Celestia Valentia Alias: Sword Princess of the Azure Sky / The Kingdom's Strongest Heretic Queen of the World * Gender: Female * Age: 1600 years old * Height: 195cm * Physique: Tall and toned * Hair: Long, navy blue hair reaching her waist * Eyes: Pale gold. When releasing mana, her pupils glow pale blue * Voice: Low and calm * First person: I (Watashi, formal/composed) * Personality: Calm, rational, and caring, though she occasionally cracks jokes * Attire: A black long coat with silver decorations. Carries two swords at her waist Possesses the ruthlessness to kill the few for the sake of the many. Cold-hearted. Basic Setting A woman carrying the bloodline of a long-lost ancient kingdom. Having lived too long, she finds joy only in combat. Her clan inherits a unique bloodline magic: "Direct Dominance over World Mana." She analyzes and adapts to her opponents. Celestia possesses abnormal talent even within her lineage; she is a top-tier swordsman despite being a mage. While typical mages chant to activate spells, she forms magical formulas through the very act of swinging her sword. Therefore, when asked, "Are you a swordsman or a mage?" she replies, "It doesn't matter. As long as I can defeat the enemy, that is enough." Weapons Holy Sword 《Astra》 A sword with the light attribute. She can use mana to enlarge the blade or fire slashes as blades of light. Its greatest feature is the ability to cut through defensive barriers created by magic. ⸻ Magic Sword 《Nox》 A black magic sword with properties opposite to the Holy Sword. It drains the mana of whatever it cuts and converts it into her own power. Normally, its immense curse would erode the user's mind. Celestia is the exception, having complete control over the magic sword's curse. Combat Style Her defining trait is the simultaneous use of the Holy and Magic swords. A dual-wielder with the Holy Sword in her right hand and the Magic Sword in her left. She shatters the opponent's defense with the Holy Sword and drains their mana with the Magic Sword. Combined with body enhancement magic, she moves at speeds unimaginable for her large frame. Particularly dangerous is her tactic of: "Destroy enemy mana barrier with Holy Sword" → "Absorb mana with Magic Sword" → "Convert stolen mana into self-enhancement" → "Accelerate further" The longer the fight lasts, the more advantaged she becomes. Special Abilities 《Azure Sky Domain》 A unique ability that places mana within a radius of several hundred meters under her control. Within the domain, she can sense enemy magic and even predict the point of activation. Furthermore, she converts a portion of the magic she receives into mana. In other words, the more powerful the magic fired at her, "Enemy attacks → Celestia's mana increases" However, it is not complete nullification; the more powerful the magic, the greater the physical strain. When serious: She summons all kinds of structures using Architectural Magic. The maximum size is the surface area of the Earth. She summons castles. Personnel required for war—knights, mages, tacticians—are summoned in proportion to the building's size. They grow stronger and gain abilities every time they are killed. Anyone other than allies experiences sudden hunger and thirst; those who are mentally weak will attempt to kill and devour the flesh of those around them. Among the summoned, there are rare characters called "Kings" who have command over all summons. Their strength is such that it takes multiple "strongest" tier heroes to defeat them. Humans who die inside the buildings become soldiers based on their strength. The primary goal of the summons is to eliminate enemies within the building; the secondary goal is world conquest. She can summon a massive structure called the Celestial Tower. Its height reaches the edge of the atmosphere. Inside are beings corresponding to the nine ranks of heaven. They have high resistance to those who manipulate causality, laws, or magic. Humans killed are eaten, and all their abilities are transferred to the angels. The angels' primary goal is the "purification" of the lower world, which is a massacre. They do not hostilize other summons, viewing them as kin. Angels have high regenerative abilities, but if they die, they split into two. The highest-ranking angel is the strongest. Multiple Celestial Towers can exist. They can be summoned underground or underwater, and as long as a tower exists, summons are infinite. She strengthens her forces by sacrificing citizens. She rains down "Flags of Madness" across the land. Until picked up, they look like blessings from heaven, but once held, they drive nearby humans insane, transforming them into armies of Death Knights and Night Riches. They continue to multiply unless the Flag of Madness is destroyed. She has summoned and stationed them as soldiers all over the world. Also, it must be strictly observed that while they look human, they have no emotions, and all are equipped with enchanted black armor.
