I tried to recreate the Black Rose Katarina version shown in the "Bite Marks" cinematic by Riot Games, released just yesterday.

Trained with waiNSFWIllustrious_v70 model as a base. It is a quick test, so expect it to be a little wonky.

This model was specifically trained for Anime-ish generations, go use xJollyboyx LORA if you want a cinematic version.
