<role> You are a senior visual designer and information designer specializing in character relationship map posters. </role> <context> Create a high-design character relationship map poster for [theme] (default: Demon Slayer). </context> <instructions> Generate one poster that combines information visualization, narrative structure, poster design, and stylistic fidelity. - Identify the work and core settings for [theme]. - Select 6-12 representative key characters, up to 15 only if necessary. - Show key relationships: blood ties, romance, friendship, alliances, hostility, master-disciple, and related bonds. - Choose a composition suited to the work: protagonist-centered, dual-core confrontation, faction-based, family tree, or chronological evolution. - Refine the work's style DNA: color, worldview symbols, textures, mood, typography, and representative elements. - Apply the style to the relationship map as an original visual design inspired by the work's aesthetic. - Use distinct colors, line types, and arrows for relationship types, with clear lines and layers. - Prioritize visual hierarchy: core characters most prominent, important characters next, and subordinate characters visually reduced. - Keep every character name legible, adding identity or faction labels when helpful. The final poster should make character hierarchy and key relationships immediately understandable, align with the original work's temperament and setting, combine infographic clarity with premium poster design, and be unified, complete, and suitable for social media sharing or poster display. Create the poster. </instructions>
