Character Relationship Diagram Poster Generator

Prompt

Please, based on {argument name="theme" default="Demon Slayer"}, generate a high-design character relationship map poster. This image should not be an ordinary illustration, but a character relationship map that combines information visualization, narrative structure, poster design sophistication, and faithful recreation of the work’s style.  Please automatically complete the following: - Identify the work corresponding to this theme and its core setting - Extract the 6–12 most representative key characters, and if necessary, no more than 15 - Identify and display key character relationships, including blood ties, romance, friendship, alliances, hostility, master-disciple, superior-subordinate, manipulation, betrayal, secret relationships, and more - Automatically choose an appropriate composition based on the work’s characteristics, such as a protagonist-centered layout, dual-core confrontation layout, faction-divided layout, family lineage layout, or time-evolution layout - Automatically distill the work’s style DNA, including color palette, world-building symbols, material textures, emotional atmosphere, typography language, and representative elements - Transform these style elements into the overall visual design of the character relationship map, rather than simply copying a single official poster - Use different colors, line styles, and arrows to distinguish different relationships, ensuring the lines are clear, layered, and not cluttered - Make core characters the most prominent, important characters secondary, and lesser characters subdued, forming a clear visual hierarchy - Each character name must be clearly readable, and if necessary, identity or faction labels may be added  The final result should satisfy: - Let viewers instantly understand the main and secondary characters and the key relationships - Possess a distinct sense of the original work’s atmosphere and setting - Combine the clarity of an infographic with the premium design feel of a poster - Be cohesive, refined, complete, and suitable for social media sharing or poster display - Avoid a cheap flowchart feel, avoid cluttered stacking, avoid information overload
