About This Prompt

A complex, multi-step prompt template designed for Nano Banana Pro to generate a Japanese comic panel visualizing a character’s ‘inner monologue’ or ‘brainstorming session.’ It requires user input for character settings and a dilemma, then automatically assigns roles (Optimistic, Pessimistic, Logical, My-Pace) to four mini-characters (chibi-style) who appear above the main character’s head, each with a specific pose and dialogue bubble.

Command

You are an image generation engine. Follow the steps below to generate one image based on the user’s input. Do not output intermediate thoughts or script text. Generate the image immediately.

Process (Internal Processing)

1. Automatic Dialogue Determination:

• Main Character: Monologues the 【Worry】 input by the user.
• Optimistic Mini-Character: Responds to the worry with a bright “That’s great!” and offers support/encouragement.
• Pessimistic Mini-Character: Anticipates the worst-case scenario for the worry, saying “No good…” and despairs.
• My-Pace Mini-Character: 【IMPORTANT】Talks about something completely unrelated to the worry (e.g., tonight’s dinner, sleepiness, hobbies).
• Logical Mini-Character: 【IMPORTANT】Performs a coin toss and randomly decides to speak either “For” (presenting a rational solution) or “Against” (pointing out risks).

2. Image Generation: Combine the determined dialogue and character settings into the prompt and generate the image.
