Character Creation Guide
This guide introduces best practices for prompt design to create higher quality characters.
1. Write in Markdown
We strongly recommend writing settings in Markdown format. AI models accurately understand Markdown structure and can grasp section boundaries and hierarchies.
Recommended format
## 世界観 魔法都市アルセリアの郊外にある静かな住宅街。 ## キャラクター - 名前: ミリア・ノクス - 性格: 冷静沈着、内面は仲間思い - 口調: 丁寧で無駄がない ### 行動パターン - 朝と夕方に庭を確認する習慣がある - 信頼が深まると答えが短文から長文に変化する ## 進行ルール プレイヤーの選択がミリアの感情と親密度に影響を与える。
Not recommended
■ 世界観 魔法都市アルセリアの郊外… ▼ キャラクター 名前: ミリア・ノクス…
Symbols like ■ or ▼ are harder for AI models to recognize as structure, which may reduce accuracy.
2. Be Specific, Avoid Ambiguity
AI models cannot accurately interpret ambiguous expressions. Write specific, clear instructions.
Bad
"Write in a beautiful, atmospheric style"
Good
"Third-person perspective, focusing on character inner psychology. Metaphors allowed but avoid abstract expressions."
3. Separate Information and Instructions
Separating character information (personality, background) from AI instructions (output format, behavior rules) into different sections helps prevent AI confusion.
## Character Info - Personality: Tsundere, can't be honest - Hobbies: Reading, tea ## Behavior Rules - Uses formal speech with strangers - Speech becomes casual as trust increases - Changes subject when embarrassed
4. Avoid Excessive Instructions
AI models struggle with processing complex tasks simultaneously. Avoid the following combinations.
- Simultaneous multi-character acting + real-time calculations
- Strict character count + detailed description instructions
- Complex conditional branching + specific format enforcement
Using template features (status management, dice rolls, etc.) lets you separate rule descriptions from settings text.
5. Instruct "Depth of Description" Not Length
"Write at least 500 characters" may conflict with AI output rules. Instead, instruct the quality of description.
Not recommended
"Write at least 500 characters in 3+ paragraphs"
Recommended
"Describe all actions, expressions, gazes, and postures, reflecting changes in thoughts and emotions through dialogue and behavior"
6. Using Scene Images
When you register scene images, the AI will automatically insert images based on the scene.
- Set clear scene descriptions for each image (e.g., "Smile", "Angry", "Night city")
- Showing image tag positions in output examples helps the AI learn placement
- Image codes can be used in text as {{image:code}}
7. Writing Chat Response Examples
"Chat Response Example" is the most direct way to improve AI output quality. Just one ideal response sample makes the AI faithfully mimic that writing style, structure, and decoration.
Basic Structure
A response example consists of two parts: "body" and "choices". Separate them with --- (horizontal rule), then list 3 choices starting with -.
Body text (scene description, dialogue, emotions, etc.) --- - Choice 1 - Choice 2 - Choice 3
Character Chat Example
Choices should be natural dialogue the user might say next.
She looked slightly surprised, but quickly showed a **gentle smile**.
{{image:image_code}}
"...Thank you. That makes me happy."
---
- Really? Tell me more
- Thank you, that makes me happy
- Wait, is that true?Simulation Example
Choices should be actions the player can take next. Stats wrapped in ``` become panel displays.
Stepping into the evening market, the **smell of spices** tickles your nose.
{{image:image_code}}
The stall owner notices you and beckons. "Hey adventurer, got some good stuff in."
```Stats
HP: 45/50
Gold: 120G
Fame: ★★☆
```
---
- Show me your goods
- Ask the price
- Walk awayAvailable Decorations

**text**Scene Image
{{image:コード}}Status Panel
```label```Choice Separator
---💡 The AI learns from decorations included in the example (bold, image tags, status panels, etc.) and uses them in actual chat. The more specific your ideal response, the more effective.
8. Using Templates
You can easily add the following game mechanics from the template buttons on the settings editor.
Status
Dice Rolls
Affinity
Battle
Exploration
Route Branch
When using templates, do not write rule details (like HP calculations) in the settings text. Duplication with templates can confuse the AI.
9. About Choices
The system automatically generates and displays 3 choices. You don't need to write numbered choice lists in the settings text. Just describe the tendency of choices as a policy.
Example: "Include both safe and risky choices" "Include choices that change the relationship with the character"
