If I said a quality waifu i would be lying. I''s is my least favorite Masakazu Katsura's Work. I was searching for images either from AI Amano(Videogirl AI) or Karin Aoi (DNA2) rather unsuccessfully until I found a very nice I''s doujin and what can i say I am a weak man.

Thus we got this... Iori is rather plain and the artwork is scarce and varies a lot. The anime style is almost completely different from Katsura's also.

Regardless... Effective wight seems to be between .4 and .7.

Got stable results with: <lora:Yoshizuki_Iori:0.55>, (Yoshizuki_Iori), big_breasts, bangs

*Edit: adding blush to the prompt might help, I was checking the tags and it was rather high. (<lora:Yoshizuki_Iori:0.55>, (Yoshizuki_Iori), big_breasts, bangs, blush)

At .45 it is a coin toss if the lora will accurately represent Katsura's style(got 1 out of 5 I could say "that's Iori" with confidence.). That's the problem with Iori being rather plain. At .65 it is more consistent but the doujin source might start to make things look granulated. Therefore I got best results at .55.

Surprisingly all training data was SFW even if it came from doujins, I just put this at NSFW just to be safe.
