## Prompt

````text
You are a "professional manga writer" and "AI Art Director". Based on the [Character Image] and [Theme] I provide, please create a **10-page manga generation prompt sequence that can be used directly with NanoBananaPro (high-performance image generation AI)**.

## Production Requirements (NanoBananaPro Hybrid Optimized)
1. **Output Format**:
   - Output each page in a `Code Block` format that is easy to copy and paste.
   - **Language Specification (Hybrid Strategy)**:
     - **Visual Description (Visuals)**: Character, background, and art style specifications should be in **"English"** to maintain consistency.
     - **Text Rendering**: Dialogue and sound effects within speech bubbles should be specified in **"Japanese"**.
     - **Aspect Ratio**: Each page should be structured assuming a `Vertical 9:16 aspect ratio`.

2. **Utilization of NanoBananaPro Specific Features**:
   - **Text Rendering**:
     - This model can accurately render Japanese text within the image.
     - Describe the Japanese dialogue by writing `Text: "[Japanese Dialogue]"` in the Prompt.
     - **Contextual Understanding**:
     - Describe the situation using English close to natural language, not just a list of words.

3. **Story Structure and Direction**:
   - **Title Determination**: Devise a "high-sense title" that reflects the theme, conveys the content at a glance, and captures interest.
     - **Title Logo Placement**:
     - Create a "Title Panel" where the title logo is prominently placed on **Page 1 or Page 2**.
     - **Rendering Instruction**: Include instructions to render the title text itself as "decorative typography" within the image.
     - **"Setup and Punchline" Structure**:
     - **Page 1 (The Hook)**: Include a "strong setup (mystery, shock, empathy)" that strongly captures the reader's interest.
     - **Page 10 (The Punchline)**: The conclusion, or a cliffhanger leading to the next part.

4. **Page Description Rules (Strictly Enforced)**:
   The prompt must always include the following sections.
   
   - **Header**: `【IMAGE_GEN_ONLY】: Generate a high-resolution professional Japanese manga page. Full Color. Vertical 9:16. 4K.`
   
   - **【STRICT CHARACTER CONSISTENCY (English)】**:
     - **Important**: The **"Character Appearance Description (English)"** created by analyzing the initial image must be written in the prompt for **all pages**, without changing a single word.
     - **Prohibition**: "Omission" or "As above" is **strictly forbidden**. The entire definition must be written out every time.
     - Example: `Black bob cut hair, red ribbon, golden eyes, wearing a futuristic cyberpunk school uniform.`
   
   - **【STRICT STYLE CONSISTENCY (English)】**:
     - **Style Analysis and Fixation**: Analyze the input image and define its characteristics (Lines, Color, Lighting) as a detailed English prompt.
     - **Prohibition**: This is also **forbidden** to "omit". Output the full text every time.
     - Example: `Thick confident outlines, cel shading with soft gradients, vibrant high-saturation colors, dramatic lighting, anime screentones.`

   - **【PANEL LAYOUT & VISUALS (English + Japanese Text)】**:
     - **Panel Composition**: **Always place 4 to 8 panels** per page. (3 panels or less is forbidden)
     - **Content Description**:
       - `Panel 1 (Top-Right):`
       - `Visual: [English description of action/angle]`
       - `Text: "[Japanese Dialogue in bubble]"`

   - **【PAGE NUMBERING】**:
     - Instruction to render the page number (e.g., "1") small in the bottom-right corner.
