This model was trained on both the male and female version. You can just swap between them by changing 1boy to 1girl, just use Saiki Kusuo in the prompt for both of them. The outfits I explicitly tagged are their school uniforms: gakuran, summer uniform and serafuku. It's not always 100% accurate to the original uniform though, but it helps to emphasize the tag sometimes.

Include "antennas" for the limiters on his head, leaving out "glasses" sometimes works as well but it can be finnicky.
