Lena Unylova from the visual novel Everlasting Summer.

This time I tried not to abuse synthetic images generated on MikuIncarnator's Lora for training dataset, but who cares right?

For the appearance use tags "UnylIll, two side up, 1girl, green eyes, purple hair, short hair, hair tie"

For the Pioneer uniform use "White collared shirt, red neckerchief, blue skirt, belt, white socks, belt buckle, black shoes, pioneer movement, breast pocket" (this time Lora actively tries to put a badge on a shoulder so put "badge, shoulder badge" to negatives)

For the swimsuit use "blue one-piece swimsuit, casual one-piece swimsuit, frilled one-piece swimsuit, covered navel, frills, bare arms, bare shoulder" (may be inconsistent).

For the dress outfit use "sundress, white dress, sleeveless dress, floral print, print dress, bare arms" (may be inconsistent as well. I tried my best to make it consistent as possible but still...)

Next ES girl probably will be Ulyana but I'm not sure.
