That's from the free Chapter 80 on the original web publisher's site
https://www.sunday-webry.com/series/983
Searching through the various chapter images there, I would expect quite a few other FTM and MTF poof transformations throughout the story, but sadly the last known scanlator of the series
Kirei Cake declared the series dropped after 6 chapters.
Strangely enough, the chapter after the free one seems to be called "The Final Story Hadacamera" instead of being numbered like the rest so the comic may very well be complete now.
