Nikke characters Sirene and Cinderella. The background is a simple futuristic space designed to make the characters stand out, featuring a wide, clean, grayish-white metallic floor with faint blue hexagonal patterns and a slightly reflective surface that naturally reflects the silhouettes of the two characters and the lighting. Behind them are large, minimalist pure white and light gray panel walls with thin blue neon lines glowing at regular intervals, creating a futuristic atmosphere. There are no complex buildings or many props; only subtle floating small light particles and translucent hologram fragments drift slowly, maintaining a minimal and luxurious mood that naturally draws focus to the two characters.
On the left, Cinderella is standing in a full-body shot from head to toe, leaning her waist slightly forward with both hands naturally gathered behind her back, expressing a polite and shy atmosphere. Her long silver-white hair flows down nearly to her ankles, depicted as very long and voluminous with each silk-like strand delicately expressed and spreading naturally to the sides. Long bangs slightly cover her right eye, through which her vivid red eyes reveal a quiet and mysterious aura. Her eyelashes are long and delicate, harmonizing with faintly blushed cheeks, small neat lips, a slender jawline, and clear, transparent skin to complete a cold yet beautiful smile. Her face is clearly visible and not obscured by hair, with even the finest changes in expression vividly depicted. She wears a uniform design featuring a dark navy double-breasted jacket with a slim silhouette that beautifully emphasizes the waistline. The jacket edges have precise blue piping and symmetrically arranged subtly glossy gold buttons for a luxurious feel. Small epaulettes are on both shoulders with gold decorative cords draping naturally to the chest. A blue patterned armband is tightly wrapped around her left arm, and a black cross strap passes diagonally across her body, connecting to a waist belt. The waist features a black belt with a metal buckle, a small key decoration, and detailed metal equipment, paired with a matching short pleated uniform skirt. She wears dark navy tactical boots with rounded toes, thick soles, and detailed metal button decorations. A uniform cap is worn neatly on her head, decorated with a gold emblem in the center and a blue band.
On the right, Sirene is standing in a full-body shot, posing cutely and naturally with both hands raised above her head, lightly holding her uniform cap. Her long dark-blue twintails extend past her thighs to near her ankles, featuring a vivid gradient to turquoise toward the ends that shines brilliantly under the light. The twintails flutter widely to the sides, creating a voluminous silhouette, and small futuristic cat-shaped mechanical devices are attached to the sides of her head. Her golden eyes have a vivid gloss, creating a bright and lively atmosphere with a pure smile, and her long eyelashes, soft facial lines, small nose, and lips are clearly expressed. She wears a uniform with a dark navy jacket that fits naturally to her body, precisely arranged with blue decorative lines and gold buttons. Shoulder epaulettes, gold decorative cords, a blue armband, a black cross strap, a waist belt, metal key decorations, and small equipment are all detailed, evoking a sophisticated future police uniform atmosphere. Short uniform pants maintain a clean silhouette while allowing for mobility, and the navy tactical boots with thick soles and rounded shapes give a cute yet practical feel. She holds her uniform cap with both hands, creating a natural movement, and her long hair flutters widely, adding dynamism to the overall scene.
