character: sailor_mercury, A medium shot from a side angle captures Sailor Mercury in the midst of a transformation, being engulfed by a translucent blue slime that is gradually turning her into a slime girl. Sailor Mercury, a young woman with short blue hair and blue eyes, is partially submerged in the viscous, glowing blue substance; her expression is one of surprise and bewilderment as the slime clings to her skin and clothing. She wears her signature sailor fuku with a blue leotard, white elbow gloves, and a circlet, though the fabric is becoming saturated and blending into the gelatinous mass. The environment is a minimal, void-like space where the glowing blue slime swirls around her body in thick, undulating waves, with small bubbles and droplets suspended in the air. The visual style is manga-inspired anime illustration with clean linework, featuring a high-contrast palette of deep blues and brilliant cyans, utilizing soft glows and fluid distortions to convey the gooey texture of the slime and a surreal, transformative atmosphere.
