Background

Stella is the princess of the Vermillion Kingdom and an A-Rank Mage Knight whose strength made her the acknowledged strongest person in her homeland. She enrolls at Hagun Academy to pursue the title of Seven Stars Sword King, confident that she can win even alone. 41 43

At Hagun, Stella meets Kashu Animusphere, another A-Rank Knight. Initially, she challenges him to a mock battle, but he refuses because he only accepts real combat. His view of fighting forces her to reconsider the limits of her own training. 43

During special training, Kashu identifies that Stella is not a natural-interference Blazer as she believed. Her overwhelming flame mana is instead tied to a dormant dragon within her. Their battle awakens this dragon concept, forcing Stella to confront the difficulty of controlling power that had always belonged to her. 54 55

Stella later reaches the Seven Stars Sword-Art Festival final against Kashu. Refusing to be treated gently, she demands an all-out battle. Although Kashu becomes champion and Stella the runner-up, her soul and swordsmanship evolve during the duel, and the two openly affirm their love and commitment afterward. 193 194

After the tournament, she brings Kashu to Vermillion to meet her family. Stella openly defends him against King Celius's objections, while Queen Astraea recognizes Kashu as the partner Stella needed. 197

Appearance

Stella is a tall, gallant young woman with long crimson hair and matching crimson eyes. Her presence and bearing are compared to a Valkyrie, while her dragon power can manifest as dragon eyes, flaming wings, and intense red-gold fire. 42 179 194

• Long crimson hair, which can become wreathed in flames during battle. 42 199
• Crimson eyes marked by a strong fighting spirit. 42
• Usually wears Hagun Academy's black-and-white girls' uniform while attending school. 42
• Gains blazing dragon wings after further training with her awakened power. 179
• Her full combat presence includes dragonfire, dragon eyes, and a golden-red greatsword. 193 194

Personality

Stella is proud, passionate, and highly competitive. She seeks strength directly rather than avoiding opponents she considers formidable, even insisting that Kashu fight her seriously in the festival final. 193

Her greatest weakness is impulsiveness. During the department-store hostage incident, she reveals herself and attacks Apostle Smile without fully understanding his Device, resulting in her own power being reflected back at her. 49 Nene Saikyo similarly criticizes Stella for being easily provoked and exposing her position through excessive force. 179

Despite her pride, Stella is capable of reflection and growth. After awakening her dragon power, she accepts that raw strength is insufficient without control, committing herself to training and gradual mastery. 55 57 She is also emotionally open with those close to her, offering Kashu support when he is troubled and defending him fiercely against accusations. 182 198

Abilities & Skills

Dragon Concept

• Grants powerful aerial mobility through flaming dragon wings. 179

• Can unleash the Sky-Burning Earth-Scorching Dragon King's Flame, combining numerous fire pillars into an all-out attack. 55

Dragon Spirit

During the festival final, Stella activates Dragon Spirit by driving her Device into her own chest, causing a storm of light and fully drawing out her dragon concept. 193

• Greatly intensifies her dragonfire and combat output. 193 194

• Represents a dangerous all-out state rather than a restrained training form. 193
