(I struggled to train the previous LoRA (which Derrian trained and uploaded it for me when I gave my dataset of Hatakaze from Azur Lane to him) and this one due to latest version of both Kohya and Derrian's scripts not working properly for me on Linux since they either give me a Nansexception error in WebUI when I use it because its loss value increases to then become NaN, or it doesn't nail the character right at all, so I had to get older commits of both scripts from GitHub. not gonna update 'em EVER AGAIN...)

Days ago, when I was browsing for LoRAs here, I came across one of Kuro/MDR from Girls Frontline: Project Neural Cloud, unfortunately it wasn't very good since it wasn't flexible at all and was missing one of her costumes being her halloween one called 'Spirit Trap'. In order to retcon this I decided to train my own LoRA of that sweet live streaming ~~thot~~ doll, this time including her halloween costume and making it completely flexible too. I gotta say that I'm really satisfied with the results, I approaced the method of using a main trigger tag for the character and a second for each of her costumes, I've only pruned her body and facial tags so that she can be flexible enough with any kind of clothing you want to prompt for her (more or less...)

Here's all prompts to generate her and each official costumes:

Kuro:

kuro, pink streaked hair, one side up, black jacket with long sleeves, black shirt with clothes writing, blue see-through skirt, black kneehigh socks with argyle, white sneakers

MDR (It's technically just a costume for her and not a separate persona ever since her true origin and name have been revealed in PNC, so please don't mistake her just as a personafied assault rifle like she originally was meant to be years ago, Mica Team's lore can mostly be confusing):

kuro, pink streaked hair, one side up, mdr, beret, tactical clothes, black jacket, black pleated skirt, brown pantyhose, black gloves, black and grey sneakers

Cocktail Observer:

kuro, pink streaked hair, cocktail observer, official alternate costume, jewelry, black cross earrings, ponytail, blue hair bow, black sleeveless dress, blue jacket, off shoulder, bare shoulders, black toeless high heels, single fishnet thighhigh, black half gloves

Spirit Trap:

kuro, pink streaked hair, spirit trap, official alternate costume, very long hair, hair bun, double bun, pointy ears, black horns, fangs, demon tail, jewelry, eye earrings, halloween costume, brown bodysuit, bare shoulders, elbow gloves, black dress, multicolored clothes, wings, brown pantyhose, bat print, black high heel boots

If you want her in any clothing you like, lower the strength to around 0.4~0.6 and put all of her costume trigger tags and some from each prompt above in negative prompt.

Trained with NAI as always, this time having used Kohya GUI from bmaltais in order to automatically guess epoch values from each folders of Kuro's dataset, I only used 1 epoch since I have an RTX 3060 and it took me an hour and 15 minutes to train her. Sadly it struggles at recreating each of her outfits correctly (except for MDR), since they're all quite complexly designed and very busy looking.
