I noticed the lack of models for the protagonists of the Rune Factory series, so here's my contribution with the male playable character, Lest!

The model isn't perfect in generating Lest's admittedly complex outfit, but adding the prompts layered clothes, white cape, segmented cape may help.

For the in-game outfits, try:

• pajama_attire, purple pajamas, long sleeves, collarbone, purple pants

• swimsuit_attire, purple swim trunks, navel, ??????? male

• wedding_attire, formal, suit, white jacket, long sleeves, blue ascot, black undershirt, white pants, white gloves

For the outfits he wears in the N¡nt3nd0 Dream manga, try:

• gym uniform, white shirt, blue shorts

• blue kagirinu, long sleeves, japanese clothes

• one-piece swimsuit, frills, frilled swimsuit, yellow swimsuit

• purple kimono, long sleeves, orange obi, japanese clothes, hair bow

• blue yukata, long sleeves, japanese clothes

Sidenote: The generator seems to think of Lest as a woman, so adding the flat chest prompt with clothing prompts may be needed.
