This is a lycors\locon you have to use the additional networks extension or the lycoris extension for this to work.

Here is the model for the younger Uzaki sister

Keyword is Uzaki_yanagi, i forgot to prune the dataset so you should tag everything you want to have i would highly recommend not using any prompt that has eyes in them and maybe use no eyes in your prompts but long bangs should do the trick.

If you like it leave a comment, like and rate that would be appreciated.

Have fun generating.
