Hiya Papaya,
Normally I don't do LoRas for characters that already exist but the ones I saw didn't support any outfits.(Or at least didn't show that they did) So here we are. Currently it only supports her Tenchi Muyo OAV look and it kinda does the nurse outfit. I might add more in a future version but I've been fighting this one on and off for the last month or so and I'm ready to move on for now. There's a decent number of screenshots from the OVAs so if you can use "retro_artstyle" for a look closer to the anime depending on your checkpoint.
Illustrious Example Prompts:
hakubi_washuu, std_outfit, long_undershirt, shorts
hakubi_washuu, nurse_dress, nurse_hat,
Pony Example Prompts:
hakubi_washuu, cowboy_shot, std_outfit
hakubi_washuu, cowboy_shot, nurse_washuu
