As always I strive to train flexible models, though if there's one persistent thing about this model it's Ai's star-eyes.
No activation is required, but adding hoshino_ai to the start of your prompt will pretty reliably reinforce Ai's key features. (ie, dark purple hair, pink streaks, the general shape of the bangs, ect.) For her idol costume refer to the showcase. (no special effort was made to train specific costumes)
If you'd like to support my training endeavors, or you'd like to possibly request model training or furry art, stop by Patreon: patreon.com/Ki2neAi
(all models will always be made freely available to everyone)
