Rant:
Searched Palm Siberia for pony and for Illustrious and the only model that i found was for SD1.5 it was really frustrating because a friend asked me to do some images and with FULL confidence i said "SURE HXH IS BIG ENOUGH"

so out of frustration i learned how to train lora in a day, its a little heavy for a lora but it yield good results

Usage:
this is trained directly from images of the anime, maybe not the best quality and even a little stiff, BUT a strength model from 0.6 to 0.8 works best because adds the flexibility of the illustrious poses, at higher strengths may leak the style of the show,

TLDR
use strength of 0.6 to 0.8 to avoid stiffness
