I am new to making LorAs so this LorA might not be the best but If I make a better one in the future, I will update it.
To summon Monika: Monika, bangs, very long hair, smile, long hair, neck ribbon, looking at viewer, ponytail, shirt, school uniform, hair bow, white bow, pleated skirt, brown hair, grey jacket, sidelocks, solo, blush, blue skirt, skirt, 1girl, breasts, blazer, green eyes,
You can change her outfit by removing anything that got to do with her school uniform and replacing it to anything you desire.
Best is 0.6 if you want to change outfits, only a recommendation.
Be sure to give me feedback on the LorA so I can improve!
