I highly doubt the chapter is online (at least not in a public capacity) cause the first 2 chapters surfaced online a month after they were released. Considering the official release date for the 3rd chapter (that's if it is the 3rd chapter) is today it's unlikely we will find it.

On an unrelated note, if you've got Magazine Special 2015-02 (the issue where Fairy Girls chapter 2 was released), within that is the Blue Mistral omake which I still can't find anywhere (i've searched everywhere)
