Mirei-san (ミレイさん) from the manga Oharamisama (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, with the weird idol/whatever the heck is going on section. 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:

mireioharami,light brown hair,green eyes,earrings
