olJapanese watercolor style in pastel colors, featuring a demon girl with black hair, red eyes, horns, and a tail, wearing a school uniform with an open jacket, white collared shirt, black necktie, and pleated skirt. She sits at a classroom desk indoors, looking directly at the viewer with a neutral expression. Her face has slender eyelashes and sophisticated contours. Big breasts are visible through her open shirt. A faceless boy is implied but not detailed. Soft natural light streams through a window, creating a pale, warm atmosphere.Oscar Lakambela
土豆character: w_(arknights). A medium shot from a front-facing angle depicts w_(arknights) standing confidently in a sunlit classroom during the early morning. She stands with a dominant posture, chest pushed forward and arms crossed firmly over her chest, wearing a confident, smug smile. She has short white hair with two red, zigzagging ahoge and downward-curving red demon horns. Her face is refined, featuring black round-rimmed glasses and translucent golden eyes with distinct black cross-shaped pupils gazing at the camera. She wears a tight, short-sleeved white formal shirt that emphasizes her very large bust, adorned with a red bowtie. Her forearms show several visible knife scars, and her nails are painted a vibrant red. On her lower body, she wears a blue pleated mini-skirt, and a grey demon tail with a red tip flicks behind her. The background is a quiet classroom with desks and chairs, bathed in the soft, pale light of dawn. The visual style is a masterpiece of clean linework and gentle colors, featuring smooth, glossy skin tones and highly expressive, detailed eyes.土豆
