2. The general consensus is that the next arc (vol 2 and 3) is almost as good, but not quite as good as the volume that was covered in this season. But almost everything after is absolutely amazing. I guess most people agree that the series does get better in general. The scope of the series was fairly limited in the first season after all. If I were to rank the volumes that I've read: 6 > 4 > 5 > 1 > 3 > 7 > 2.
3. Yes, quite a lot. However, it takes some time for it to get started. We definitely won't be seeing any hints of romance in the next season.
4. Well, they actually met in the epilogue of volume 1. However, the anime chose to skip it because the epilogue actually time-skips quite a bit and spoils a lot of upcoming stuff. Volume 2 and 3 serve as a fill-in for that timeskip gap, so the anime's planning on adapting the series linearly and leaving volume 1's epilogue for later. I'm almost certain that them meeting will be adapted in the final episode of the next season.
5. It's pretty stretchable from the point the anime ends off at. However, the series is already at volume 10 in Japan, and the anime only adapted one volume, so there's a whole lot of material left to cover. I've only read up to volume 7 because that's where the English releases are at, but an end point is visible and I don't think it will take too long to get there. I'm guessing the series might end around the 15th volume mark... unless if more stuff is introduced in the later volumes.
6. Well, as much as I liked the next volume (vol. 2), it basically served as set-up for the volume after that. Because of that, vol. 2 kinda lacks a climax and isn't the most fulfilling read. Of course, this isn't particularly uncommon in LNs. Multi-volume arcs are quite common within LNs, I'm just hard-pressed in finding stuff to criticize about 86, lol. If anything, this is a non-issue for the anime, since the next season should cover volumes 2 and 3, since they serve as one big arc. The only other thing I can complain about is that I found the 7th volume to be too heavy on fluff and romance and didn't progress the plot much and lacked action. However, I am very much in the minority with this opinion, since most people loved that volume.
