Irina Jelavić from Assassination Classroom trained on 42 SFW and NSFW images. Make sure to read everything because there's a few... quirks with this lora you'll want to know about.
Use irina jelavic to generate Professor Bitch. For her full outfit, use:
black choker
white jacket
black sleeveless shirt
white skirt
black belt
high heels
I also included as many images of her in her bikini as I could find (which isn't many) and managed to get surprisingly consistent results for it as well. It's not perfect, but a lot better than I was expecting:
black choker
irinabikini
Since there's very few fanart images of her, most of the images I used were taken from the anime itself which I think ended up influencing the style of the lora. I tagged all the anime images with anime screencap so you can try putting that in the negative prompts to see if it improves anything. Besides that here are a couple other things:
when generating her in her normal outfit, I recommend adding bra, black bra, flower in the negative prompts
she's wearing a choker in 95% of the images in the dataset and while I haven't had too much issue generating her without it, you might want to put choker, black choker in the negative prompt if you don't want it
If anyone has any images of her you think I probably missed (fanart, not from the anime - I already have more than enough of that), feel free to post them in the comments or send them to me via Discord (GuileGaze#4436). I want to make a v2 with a better dataset to iron out the kinks, but it can be tedious finding quality images for training.
