Character Design
Character Design Guide
Strong characters usually begin with language, not visuals. Define the role, tone, values, and limits first, then match the appearance later. This page explains that workflow in a public format.
1. Four elements to define first
Write one sentence that explains what this character is especially good at discussing.
Give the character a voice that a reader can recognize quickly: formal, dry, warm, sharp, and so on.
Define what the character prioritizes and dislikes. This is the core of decision-making.
Specify what the character avoids or handles poorly so the profile stays believable.
2. Separate tone from values
Tone is surface; values are structure. If you mix them together, you end up with characters that sound different but think the same way.
For example, two calm characters may still diverge sharply if one is numbers-first and the other is fairness-first.
3. Add VRM later
VRM assets help presentation, but they should support a character that is already coherent in text. Once the role and voice are stable, use the VRoid guide to align the visual layer.
That order keeps the profile useful even before asset work is complete.
4. Build a profile that lasts
Profiles based only on short-term jokes tend to collapse when the topic changes. Profiles built from role, values, and clear limits remain readable across many prompts.
A strong character should feel real even when someone only reads the profile page. That matters for both product quality and public content quality.
