Here we have the youngest protagonists in the series, Aaron and Aria!
The model may have difficulty with separating the characters from each other, but adding the prompts 1boy and 1girl, twins, duo may help. To generate the characters separately, use the 1boy prompt for Aaron, and the 1girl prompt for Aria. Unfortunately, Aaron and Aria do not have alternate outfits.
Sidenote: When generating both characters at the same time, it is highly recommended to use the BREAK prompt between character and clothing prompts. See example images above.
