Unfortunately, the Yugi Yamada books haven't sold particularly well for Juné. It's too bad, because I feel Yugi is a very talented manga-ka and everything we've published - Picnic, Don't Blame Me, Glass Sky, Laugh Under the Sun, and Close the Last Door - is worth a read. Close the Last Door was also one of those titles afffected the Biblos/Libre situation. Had Biblos not gone under, forcing us to stop and recontract all our licenses with Libre, then we probably would have continued the series by now.
I am told Juné still has plans to continue Close the Last Door - it just may come at a time when market conditions are more favorable. Buy more Yugi Yamada! As always, that's the thing that can speed up the process of when a book like Close the Last Door gets back on Juné's publishing schedule.
