(art from Nanashi as always: https://www.deviantart.com/stoichion)

This outfit is rewarded to the player for completing the "Into the Jungle" area, with any of its endings. After you get it once, you can have Kaliska wear it at any time in the game (has a respective sprite of course).

Yeah, it's a bit fanservice-y and not "the" most lore-friendly outfit so far, but...
...
"throws smoke bomb"

You can view it in HD here, the file is a bit too large for itch.io: https://drive.google.com/file/d/1GEhYSQO1QcTdO_cUku0vnQUGsDZGREzO/view?usp=shari...

Because Kaliska was the first of the girls to get her art redone, there were still some things undecided (if you see the old posts, the bust was only above her belly button), so I had Nanashi extend her others a bit too, so that it's in the same style as the other girls (Hatchy, Nahuatl, Anacaona):

Right now I'm having him help with some technical art parts of the game (will post once it's done), and after that it's back to designing alter costumes for Hatchy (cold weather and formal outfit are the next ones). After that I'll have him go for either Azar or Nao (your choice actually, you can comment which one you want).
