Taniyama Sayaka - Roshidere

https://civitai.com/models/1237474/taniyama-sayaka-roshidere

Only outfit it really has is her school uniform, but it seems pretty flexible with her hairstyle if you want to change it. Oh actually it can do a pretty good swimsuit from one of her official arts. Make sure to add "hairclip" or "red-framed glasses" to prompt or negative depending on what you want.
