You can recreate the iconic panel with this Lora.

3boys or 3girls if they are all the same gender. You can also use 1girl and 2boys if it's mixed.

The best way to use this with character Lora is to generate each character individually then use photo editing software to combine them but if you guys know better way to do that, feel free to share.

Additionally, you can create an image with 3 characters then Inpaint each panel with whoever you want like I did with the Genshin images there.
