Daganronpa, eh? I'm not watching that which explains why I didn't recognize him. Then again, he's good-looking. Maybe I should be watching it. (Curiously even though I'm not watching the show, I'm lurking in the thread because for a while I thought I might watch it. But I never got around to trying it.)
TP published 10 volumes of Dazzle before going defunct. (That's another series where the next volume was announced but never materialized.) The series is currently at 13 volumes in Japan and still running according to BU Manga.
With GH v12, it's especially frustrating since Del Rey had finally announced its release. We were promised it but it never happened. There are a few other favorite titles that were in similar situations -- final volume announced but the company folded just beforehand. I think GH and Two Flowers for the Dragon (CMX) were the ones like that that hit me hardest.
