Dorothy-chan (ドロシーちゃん) from the manga Oharamisama/The Oharami Maiden (オハラミサマ) by Hanamori Bambi (花森バンビ). A minor character who appears at the start of chapter 3, v2 includes images from both the weird idol/whatever the heck is going on section in the preparatory release and the private party from the final release. Unlike Mirei, Dorothy didn't really change between the two. Image set was limited and is all NSFW so take precautions as needed. I've made some assumptions with hair/eye color, so change it to what you want to.

Prompt:
