I recently discovered on that there was a shit ton more Furrian Propagation Log content that was just lying around on Pixiv.
So, being a completionist, here's ALL OF IT, from the first Lona sketch in 2015 to today, translated and in chronological order!

I recommend perusing from start to finish, but for convenience, here's a quick list of all the multi-page manga sequences:

8 - FPL 1 Rough Draft (2 pages, left untranslated)
21 - FPL 4.2 (4 pages)
27 - FPL 4.3 (3 pages)
37 - Marie (3 pages)
69 - Limi (2 pages, unfinished)
72 - Rab+Bit (3 pages)
79 - Marie (3 pages)
94 - Vale (10 pages)
115 - Limi (3 pages, unfinished)
125 - Shallue+Kuroro (5 pages)
142 - Jun (2 pages, unfinished)
155 - Vale (5 pages)
171 - Limi (2 pages)
