The next chapter is annoyingly the last chapter before a side-volume. It's mostly comprised of art, raunchy mini-comics and travel guides. I'll try to go through it quick to get back to the story proper.
EDIT: Actually, there will be one more chapter before the next volume. I managed to get a hold of the new re-releases of volumes 1-6 and it has a bonus chapter for each volume that wasnt in the original release, so we'll be doing that one before moving on. It's a saeki chapter too, so saeki fans can rejoice. We'll also be working on the new bonus chapters for the previous 5 volumes as well. I don't have the new versions of the next 4 volumes yet, though.
