I recall where manga is at now (ch 9) is around 40 in the WN. After some major plot points, including a couple new recurring characters, Sadith, Fiancei, etc are shown in late 80s briefly. I forget where, but Eirth does meet up with his maid again at some point. Same with his childhood friends. They do actually stick around for a bit. At around late 220 or 230, after winning a major fight that reminds him of the start of his journey, he reconciles with most characters from the capital (including most other characters up to this point). There's a mini arc right after dedicated to the characters he doesn't reconcile with. I stopped shortly after that; he is alone again for the most part where I stopped in like 240s. Rough translations only go so far and it's a good stopping point. Eirth more than proves his ability in this time, and every other character becomes distinctly aware of it and his exploits.
