Mika, the smug surfer from "Resort Boin" (yes, I'm not putting her ridiculously long surname in the title).
Her design in the visual novel and the anime are sightly different, so I decided to go with the great original art by Happoubi Jin. IMPORTANT: while her casual clothes are properly learned, the bikinis (because there are two) are barely hanging there, so you may get just something close.
Trained on NAI. Recommended weight of 0.7 (bikinis may need 0.8)
Common trigger: mikaboin, tan
Extra prompt: tanlines
Casual clothes
necklace, bracelet, tank top, floral print, zipper, red bra, yellow pants
Red Bikini
necklace, bracelet, red bikini, side-tie bikini bottom
Striped Bikini
necklace, bracelet, striped bikini, multicolored stripes, side-tie bikini bottom
Notice that I've added "tan" to her actual trigger; you'll need it to get her proper skin color. Depending on the outfit -or lack of- you can leave "tanlines" out
Tanlines as usual will require some luck, specially outside of the front view
A bit short on data for what I would have liked, but the anime was of no help here, apart of some images for the tanlines
