This is an original character designed for this scene, not an existing copyrighted character. Describe the figure exactly as follows:
A petite girl about 150cm tall with a slender, light build, narrow shoulders, and a youthful face. She has long, silver-white hair reaching her waist, consisting of fine, soft straight strands that naturally split into thin bundles. Heavy bangs cover most of her forehead and eyebrows, with deep red eyes peering through. Her expression remains calm and composed even in combat, with a faint, thin smile on her lips, conveying a sense of ease and arrogance, as if she is merely dealing with a weak opponent.
She wears a modern, black-based military uniform of the Student Council: a slim-fit jacket with silver trim, a deep red armband, epaulettes, a few medals, and thin decorative chains. She wears a white shirt, black short pants, black lace-up military boots reaching below the knee, and a slightly oversized black military cap. The decorations are asymmetrical, giving her the unusual prestige of a student who also serves as the supreme commander of a giant military organization.
She wields a slender ceremonial straight sword with a silver blade and a black hilt, fitting her uniform's design.
The setting is the Student Council room after school, featuring a massive crimson throne, old desks, scattered documents, and a large window. The girl is not sitting on the throne; she has stepped a few paces forward and has just swung her sword in a horizontal slash. She does not jump or lean back violently, but steps forward quietly with one foot, rotating her hips and shoulders slightly to swing the sword with precise, skilled movement. Her silver-white hair flows horizontally due to the speed of the strike, though her head and bangs maintain their shape and her cap only tilts slightly.
Her gaze does not follow the sword; her deep red eyes are fixed on the intruder with a thin smile, showing utter composure.
The massive crimson throne remains behind her. Outside the large window is a magical city past twilight, with distant skyscrapers and pale blue magical circles floating in the sky. The room is mostly dark, lit only by the cold blue light from the window and a red magic lamp on the desk. There are no flashy light effects from the slash, only the silver blade reflecting blue and red light with a thin trailing line.
The camera angle is low, looking up from a diagonal front perspective, as if from an intruder entering the room. The edge of an open door and a few documents fluttering from the wind of the slash are in the foreground. The composition forms a large diagonal line from the crimson throne, through her flowing silver hair, her black military uniform, to the tip of the sword.
The overall atmosphere is not one of a "brave girl fighting," but of a powerful leader who barely had to stand up from her throne to eliminate an intruder, maintaining her bored composure and arrogant confidence throughout the action.
