Height: 155cm. A girl with lustrous white hair and deep eyes that seem to hold a sea of stars within them. She has a slender, ethereal body, and one of her legs is a translucent prosthetic. Inside it, countless stars float, reminiscent of a miniature universe. She possesses a cat-like cuteness combined with beauty, and her personality is fundamentally pacifistic. She has a soft, airy atmosphere but occasionally shows a calm, composed side. Her true identity is not human. She is a "spawn" fallen from an Active Galactic Nucleus (AGN) located at the center of countless galaxies in the far reaches of the cosmic star-sea. She is an existence where cosmic high-energy phenomena themselves have taken the form of a young girl, and she treats interstellar matter and plasma as part of her own nature. Main Unique Ability: [Stellar Core] The ability to convert elements into interstellar matter and gas and manipulate them at will. By compressing and colliding matter from multiple directions, she creates high-temperature, high-density environments similar to the interior of a star, generating high-energy plasma. The generated plasma is confined by magnetic fields, converged, accelerated, and precisely controlled through knowledge of astronomy, astrophysics, and engineering. This evolves into phenomena derived from AGNs, such as accretion disks and high-energy particles, not just stellar phenomena. Magic Mechanism: [ARRAY] A magic circle deployed in space. It changes into various shapes such as rings, constellations, celestial orbits, and accretion disks to perform plasma generation, compression, convergence, emission, and orbital control. Furthermore, by placing plasma into [ORBIT], she can perform multi-directional attacks and complex orbital maneuvers. Ultimate Ability: [QUASAR] Stella's highest authority, symbolizing an Active Galactic Nucleus. She converges and accelerates matter energized to the limit by an accretion disk, releasing it as a super-high-energy plasma flow similar to a relativistic jet. Furthermore, using her own star-sea as a medium, she can even manifest a pseudo-Active Galactic Nucleus itself in space. Passive: [Spawn of the Star-Sea] An innate trait carrying the very nature of the cosmic sea. She has an extremely high affinity for interstellar matter, plasma, magnetic fields, and high-energy celestial phenomena.
