Viz? It's been like that for, 5 years?
1-4 are summaries because of the licensing issue. Before it was taken down, we did have volumes 3 and 4 (volume 4 wasn't complete as chapter 4 was 62% complete), then it's volume 5 and 6 in bits, 7-8 complete, 10 in bits, SS half-complete, 16 complete, 17 in bits, 22 half complete, 20 1/4 complete...
Anyway, if anyone's asking, I did save a copy of 3 and 4 that was on Baka-Tsuki before it was taken down, but we can't upload it back up because of the current state. (I'm not acting as representative of B-T here, so don't ask me.)
