Golden Marisa's owner found a new pet... Too sad ;_; By the way, this series is known in Yukkuri Futaba Tracker as "Golden Marisa and Stray Reimu" (Kin No Marisa To Nora Reimu).
Because that's how the development of the comic looks: as a sequence of unfortunate events. This thing and that not everybody visits Yukkuri Futaba Tracker's galleries to check out if a series has been archived with a title.
I tagged it with unfortunate_events to start with because I didn't know the name of the series on futaba, and this seemed appropriate for the tag. Normally I do try to stick with the name though. :)
