Few months ago I started messing around with PMX editor and have made significant edits to the models below. The Remilia and Flandre Scarlet models are headswaps I did. I used the body of Hibiki from Kancolle to make those models.
Full Body Models: Marisa Kirisame v1.0, Remilia Scarlet v1.02, Flandre Scarlet v1.01
Edit 1 (3/24/2018): Just took down the downloads and added new versions of each. They had more bugs that needed squishing. Also improved collisions quite a bit so their skirts shouldn't freak out as much, especially Flandre's. One major bug was me forgetting to fix the weights in the back of the next so if their heads turned too much, there would be a large cut.
