20+ Gemini Nano Banana Pro Prompts for Manga: Copy & Paste
I used to spend hours sketching out rough storyboards and trying to get the shading right on my manga panels. But recently, I started using the Gemini Nano Banana Pro model, and it honestly changed my workflow. It understands the distinct difference between a Shonen action line and a Shojo sparkle in a way previous models just couldn’t grasp.
You can try these prompts directly in Gemini, but keep in mind you usually need a paid Gemini 3 Pro account to access the best image generation features. If you want to start creating without a subscription, I recommend checking out Mew Design. It’s a AI design agent platform powered by Nano Banana Pro and Gemini 3, but it’s tuned with real design aesthetics. You get free AI credits just for signing up, and you can generate single characters or entire batches of consistent comic panels using simple natural language.
How to Generate Manga/Comic with Gemini Nano Banana Pro
Generating manga requires more than just a good prompt; you need control over the output. While raw models are powerful, they often struggle with keeping a character looking the same across different panels. Here is a simple workflow using Mew Design to keep your characters consistent and your panels sharp.
Step 1: Go to Mew Design Log in to your Mew Design account. If you are new, you will automatically receive free AI credits upon registration to start testing the Nano Banana Pro model.
Step 2: Input Your Manga Prompt
Go to the Design interface. You can type in natural language or paste one of the structured prompts from the list below. Choose either Fast Mode or Deep Mode depending on your needs. Fast Mode is ideal for generating a single detailed image, such as a manga character. Deep Mode is better for automatically creating a multi-image series.
Step 3: Refine with Conversation
This is the best part about using an AI design agent. If the generated result isn’t quite right—maybe the manga ink is too heavy or the character’s eyes are the wrong color—you don’t need to rewrite the whole prompt. Just click the Refine button and type a follow-up command like, “Make the lines thinner” or “Change the background to a sunset,” and Mew Design will edit the image for you.
Step 4: Generate a Series
For a comic, you need multiple panels. You can ask Mew Design to “Generate a series of xx vertical manga panels based on the same character in the reference image.” to quickly build out a full storyboard or comic strip without starting from scratch every time.

How to Write the Best Gemini Nano Banana Pro Prompts for Manga & Comic
Getting the exact look you want for your comic isn’t just about describing the character; it’s about describing the medium and the layout. Nano Banana Pro needs to know you are making a comic, not a photograph.
Here is the basic formula I use: [Manga Sub-genre] + [Panel Description/Layout] + [Character Details & Dialogue] + [Artistic Technique/Medium] + [Ratio]
For example, instead of asking for “a boy playing soccer,” try: “Sports manga panel, low angle action shot, a boy with messy hair and a number 7 jersey kicking a soccer ball, shouting ‘Goal!’ in a jagged speech bubble, speed lines, sweat details, high contrast black and white ink. —ar 2:3”
Tips & Tricks for Generating Manga/Comic with Nano Banana Pro
- Mind the Ratio: Use
--ar 2:3for standard manga pages,--ar 16:9for cinematic wide panels, and--ar 9:16for Webtoon style scrolling comics. - Define the “Ink”: If you want that authentic printed look, use keywords like “G-pen,” “Screen tone,” “Hatching,” or “Black and white ink.” Without these, the AI might give you a 3D render.
- Dialogue Control: You can specify what characters are saying by adding phrases like speech bubble saying “Hello” in your prompt. However, for perfect text, it’s often better to generate empty bubbles and add the text later in Mew Design.
- Panel vs. Illustration: Specify if you want a “Manga page layout” (which creates multiple boxes) or a “Full page illustration” (which creates one big image).
Summary
Creating manga art doesn’t have to be a struggle with anatomy or perspective anymore. With these [Gemini Nano Banana Pro prompts(https://docs.mew.design/blog/nano-banana-pro-prompts/), you can quickly generate storyboards, detailed character concepts, and finished panels.
