Prompts for turning characters into SSR cards with Generative AI Nano Banana 2

While browsing X, I saw that Midori-san had released a prompt for creating social game-style SSR card images based on your favorite images. It's designed to be used with Nano Banana 2 and comes in two versions: an illustration version and a version that makes it easier to retain the original style or live-action look.

In this article, I'd like to focus on introducing the illustration version of the prompt.

The idea of completing it as a card image, not just a character drawing

Looking at the released illustration version of the prompt, it specifies everything from the start: creating a high-quality social game-style SSR card image using the attached character, optimizing the character's pose for a card, setting the aspect ratio to 3:4, and even including the card name and any text you want to add. This part is very important.

For example, the 3:4 vertical aspect ratio alone makes it look quite like a card. Instead of thinking of it as a normal illustration, you are deciding how it will look on the screen from the beginning. The same goes for the pose; instructions are included to shift it toward a presentation that looks good as a card, rather than just a person standing there.

Moreover, this prompt isn't just about making the art style look like a social game. It states that the card name, additional text, and other characters should all be optimized to match the card's atmosphere, so the composition, presentation, and text are all bundled together from the start.

In image generation, it is often easier to keep the whole thing cohesive if you decide how you want it to look in the end first, rather than specifying what to draw in detail.This prompt is exactly that pattern; the focus is on making it work as a single card rather than just drawing a character. I think that's why it not only looks flashy but also looks authentic.

Turning note friends into cards

Now, I will actually turn some characters into cards. With prompts like this, actually turning someone into a card really conveys the vibe. Especially when you use people you interact with on note as subjects, it doesn't just end as a sample; it becomes fun to see how much of that person's personality can be expressed within a single image.

Ma-Lion-san

Speaking of Ma-san, it's "manga". So, first, I made that the theme of the card. I feel that if you honestly include the first thing that comes to mind when you think of that person, it's easier to make it look like a card.

The card that Ma-san made herself is here. Seeing what she made herself, I could see a little bit of how she wanted to present herself, which was another interesting part.

Kuitaro-san

Speaking of Kui-chan, it's the shrimp character. I made the theme Kyudo (Japanese archery). It's interesting that the shrimp character is being forced into Kyudo attire, and I think this is the fun part of turning things into cards.

By the way, the prompt above only produced a somewhat subdued card, so I added the instruction "please make it flashier" to get this card.

Pandive-san

Speaking of Pan-chan, for some reason the barbecue article sticks in my mind. This way of remembering things is surprisingly important, and it serves as a clue when turning that person into a card. Perhaps because the original note image was greenish, it turned into a neon-sign-like panda.

It became an SSR card where the word "dive" remains clearly, and they are enjoying a bamboo barbecue with their family.

Summary

The strength of this prompt is that it doesn't just end with drawing the character. It works well for uses like turning note friends into cards; it's a bit funny and also quite impressive to look at. Being able to present them with a little extra special feeling while keeping the character intact was also a fun part of this prompt.

If you're interested, try turning your close note friends into cards and playing around with it; it might be more exciting than you think. Please give it a try!
