To avoid any confusion, I just want to clarify that there are 5 chapters of this manga, not 6/7. The paid published version only has 4 chapters plus the extras, and the 5th and final chapter seems to only be available on Pixiv Comics here https://comic.pixiv.net/works/11313.
Unfortunately a good chunk of the chapters were wiped from the Pixiv version at some point, and I'm not sure if the physical book includes the last chapter either, so as far as I can tell there's nowhere to read the whole manga in one place.
