Update (9-16-25): I added a V2 of Chika (I wanted to do Ai, as well, but I appear to have not backed up her dataset when I upgraded my PC, RIP :'( ). V2 has some tweaks to the tagging, training settings, and I removed some questionable quality images.

Usage tip: In V2, I pre-tagged Chika and her outfits (see the trigger word list). However, if you're trying to get as close to the anime as possible, you may want to try swapping out the Chika keyword for Illustrious XL pretrained keywords fujiwara chika and kaguya-sama wa kokurasetai ~tensai-tachi no renai zunousen~ instead; all V2 preview images do not use this, though, and I didn't tag my dataset with these keywords.
