It's not strange when your group is running on the good will of people who are wary of getting in trouble (in their country) for uploading potentially illegal scans. There was a different scanner for the Kirara raw for issue 6.
And that's understandable. That said, while it's difficult to get one's hands on archived Kirara issues, SD was also completely in the later volume compilation of Noisy Citrine, Symmetry Diamond, and Last Agate. If you can't get a hold of that in Japanese yourself, you could get someone to buy it and scan it. I own it in Japanese myself, but I don't have a good scanner and I'm really not willing to tear apart one of my manga. =P
