一套"主角风格宇宙"模板，让 AI 严格按照既定日式插画风格（画风、色调、质感、光线、构图、氛围）为不同角色生成视觉一致的形象，适合系列角色插画创作。

中文版提示词

请严格遵守既定的"主角风格宇宙"进行创作。风格基准：日式插画风格、笔触细腻柔和；低饱和度的暖棕、黑、灰为主；画面带轻微颗粒感和复古滤镜；通透柔和的暖调光从人物前方偏上照射，形成自然浅淡阴影；平视视角、全身或半身构图、背景虚化突出主体；整体慵懒、治愈、安静的氛围。本次角色描述：[详细描述新角色的外貌、服饰、表情和姿态]。背景为简洁纯色渐变（浅米黄过渡到柔和浅灰），沿用主角设定的柔和暖光与平视视角。强制一致性：本角色必须与主角（黑色短发、棕红眼眸、慵懒姿态的男性）看起来出自同一位插画师、同一部作品、同一种渲染引擎，皮肤质感、衣料褶皱、光线逻辑完全一致。负面提示词：风格不一致、高饱和度、赛博朋克、厚涂、水墨、3D 渲染、复杂背景、强烈对比阴影、线条生硬、恐怖氛围、夸张表情。

英文版提示词

Strictly follow the established "protagonist style universe". Style baseline: Japanese illustration with delicate, soft strokes; low-saturation warm browns, black and gray; slight grain and a vintage filter; soft, translucent warm light from above-front, creating natural shallow shadows; eye-level view, full or half-body composition with a blurred background to highlight the subject; an overall lazy, healing, quiet atmosphere. Character description: [describe the new character's appearance, clothing, expression and pose in detail]. Background: a simple pure gradient from light beige to soft gray, using the protagonist's soft warm light and eye-level view. Forced consistency: this character must look like it comes from the same illustrator, same work and same rendering engine as the protagonist (a man with short black hair, reddish-brown eyes and a lazy posture); skin texture, fabric folds and lighting logic must be identical. Negative prompts: inconsistent style, high saturation, cyberpunk, thick paint, ink-wash, 3D render, complex background, strong contrast shadows, stiff lines, horror atmosphere, exaggerated expressions.
