Character Poster Narrative Relationship Map

Generate a highly designed character relationship poster for [主题]. This should not be a standard illustration, but a relationship map that blends information visualization, narrative structure, poster-level design, and a strong recreation of the original work's style.

Automatically complete the following:
- Identify the original work and its core setting
- Select 6 to 12 of the most representative key characters, up to 15 if necessary
- Identify and show the most important relationships, such as blood ties, romance, friendship, alliances, hostility, mentor-student bonds, master-servant dynamics, manipulation, betrayal, and hidden connections
- Automatically choose the most suitable composition, such as protagonist-centered, dual-core confrontation, faction layout, family tree, or time-evolution structure
- Extract the work's style DNA, including color palette, worldbuilding symbols, material language, emotional tone, layout rhythm, and iconic motifs
- Transform these style elements into the visual design of the entire relationship map, rather than simply copying an official poster
- Use different colors, line styles, and arrows to distinguish relationship types while keeping the layout clear and readable
- Make core characters the most prominent, secondary characters less prominent, and peripheral characters more subdued to create a clear visual hierarchy
- Ensure every character name is clear and easy to read, adding identity or faction labels when necessary

The final result should:
- Make the main relationships understandable at a glance
- Strongly evoke the recognizability and world setting of the original work
- Combine infographic clarity with a premium poster design sensibility
- Feel unified, refined, and complete, suitable for social sharing or poster display
- Avoid looking like a cheap flowchart, feeling chaotic, or becoming overloaded with information
