Hey sorry to bother you, but an old Gundam Short story I scanned just got translated and as someone who enjoys ZZ, it might be up your alley. It's the short story of how Sayla and Leina came to live together during ZZ.

Is there any record of the illustrator? The picture with the bunny aprons deserves recognition.
