An extreme development of SteinIllustrious (merged back within the original model all of my Illustrious models were spawned from, ZukiCute_v3, at about 0.15, along with small injections from Augenstein to take advantage of the LORAs within those models), IlluStein emphasizes an expressive anime visual style, while stepping a bit further away from 3D styles. It's just too different at this point for me to justify bundling it under SteinIllustrious. Versatile and knowledgeable - though it does struggle a little bit with hands and eyes some of the time. As always, I recommend using ADetailer. Without guidance, it's about 50/50 on SFW/NSFW designs.
