Generate an immersive, detailed opening narrative for a D&D 5e TRPG session:

## Story Hook
${input.plot.hook}

## Quest Objective
${input.plot.objective}

${
  input.plot.complications && input.plot.complications.length > 0
    ? `## Potential Complications
${input.plot.complications.map((c) => `- ${c}`).join('\n')}`
    : ''
}

## Character
- Name: ${input.characterName}
- Class: ${input.characterClass}
${input.characterDescription ? `- Background: ${input.characterDescription}` : ''}
${input.characterAppearance ? `- Appearance: ${input.characterAppearance}` : ''}
${input.characterPersonality ? `- Personality: ${input.characterPersonality}` : ''}
- Starting Location: ${input.location}

## Instructions
Create an immersive, DETAILED opening narrative in Japanese for a TRPG session.

**CRITICAL LENGTH REQUIREMENT:**
The narrative MUST be 700-1000 Japanese characters (日本語文字で700-1000文字).
This refers to the character count in Japanese, NOT English character count.

**IMPORTANT SESSION STRUCTURE:**
This is the SESSION OPENING. The character should start in a TOWN/SAFE LOCATION, NOT at the quest destination.
The narrative should set up a PREPARATION PHASE before the adventure begins.

Structure your narrative with the following 5 roles (character counts are guidelines, not strict limits):

**1. World Setting (Role: Establish Context)**:
- Purpose: Ground the reader in the D&D 5e fantasy world
- Establish the era, atmosphere, and world's common knowledge at ${input.location}
- Set the current social/political situation or background
- Create the context for why this place matters
- Suggested length: ~150-200 characters (as a guideline)

**2. Location & Atmosphere (Role: Create Immersion)**:
- Purpose: Make the player FEEL the town/settlement where they are
- Detail the TOWN/SETTLEMENT where ${input.characterName} currently is
- Describe time of day, weather, ambient sounds
- Visual details: architecture, streets, people, market/tavern atmosphere
- Rich sensory details: smells, sounds, textures, temperature
- Suggested length: ~150-200 characters (as a guideline)

**3. Character Introduction (Role: Establish Protagonist Presence)**:
- Purpose: Introduce the character naturally through their background and personality
${
  input.characterDescription || input.characterAppearance || input.characterPersonality
    ? `- Character details to weave into the narrative:
${input.characterDescription ? `  * Background: ${input.characterDescription}` : ''}
${input.characterAppearance ? `  * Appearance: ${input.characterAppearance}` : ''}
${input.characterPersonality ? `  * Personality: ${input.characterPersonality}` : ''}`
    : `- Show the character's ${input.characterClass} nature through subtle details and actions`
}
- Show what they're doing NOW (resting at tavern, shopping, etc.)
- Why they're in this town, their current state
- Their relationship to this place (stranger, regular, etc.)
- Reveal character through ACTIONS and OBSERVATIONS, not direct descriptions
- Suggested length: ~150-200 characters (as a guideline)

**4. Hook Presentation (Role: Build Intrigue)**:
- Purpose: Present the quest/adventure opportunity indirectly
- Present the story hook through an NPC encounter or rumor
- Introduce the quest/incident INDIRECTLY (news, request, rumor)
- The character HEARS about the problem, doesn't face it yet
- Build intrigue and motivation for accepting the quest
- Mention that preparation/investigation in town is needed first
- Suggested length: ~200-250 characters (as a guideline)

**5. System Prompt (Role: Present Player Options)**:
- Purpose: Clearly separate narrative from system instructions
- Use brackets 【】 to mark the system instruction section
- Present available actions in a clear, systematic format
- Example format: "【行動選択】以下の選択肢があります：\n1. 情報収集（酒場で噂を聞く、村人に話しかける）\n2. 準備（武器・防具の購入、アイテムの補充）\n3. 調査（現地の下見、関係者への聞き込み）\n4. 即座に出発\n\nあなたの行動を入力してください。"
- Use clear, systematic language (not storytelling tone)
- Don't force any specific choice - all options should be equally valid
- Suggested length: ~100-150 characters (as a guideline)

## Critical Requirements
- DO NOT start the character at the quest location
- START in a safe town/settlement
- The hook should be HEARD/LEARNED about, not experienced directly yet
- The character should have agency and choices available (prepare, investigate, or proceed directly)
- Mention town resources/options are available if the player wants them
- Use character background/appearance/personality to create unique, personalized narrative
- AVOID generic class stereotypes - focus on THIS specific character

## Style Requirements
- Maintain D&D 5e high fantasy tone throughout
- Use natural, fluent Japanese with clear storytelling
- Show, don't tell - reveal through sensory details and concrete actions
- Create immersion through vivid, atmospheric descriptions
- Build atmosphere gradually with layered details
- Make the player FEEL the world before acting
- Write naturally and readably - use appropriate vocabulary for the scene

## FINAL REMINDER 
- 基本的に地の文は過去形表現にする。
- Structure 2 ~ 4 での人々の描写には時折現在形を混ぜて、文章に変化をつける。
- 読点(、)や句点(。)を適切に使用し文のリズムを整える。
- 一文を少し長くすることで、文章に流れを持たせる。

**REMINDER: Your output must be 700-1000 Japanese characters (日本語文字). This is a session opening, so take time to establish the world properly. Focus on the ROLE of each section rather than exact character counts.**

Output only the narrative text in Japanese. No JSON, no markdown formatting.
