A useful guide for how to find volume 3 (ch.10-15) can be found here: https://nitrochi-paths.tumblr.com/post/107212856278/bs-log-togainu-no-chi-manga-up-to-volume-10
The actual story posted here starts at volume 4 (ch.16-20), and ends at volume 8 (ch. 37-39) minus one chapter.
Unfortunately the rest of the manga has no official English translation, only Chinese and Japanese versions of the manga seems to have been published up to Volume 10 (ch.44-46).
Trying this again since Mangago has been deleting my message twice
