Since someone mentioned 覇剣の皇姫アルティーナ before, I thought I'd mention that 覇剣の皇姫アルティーナ III is slated for a June 29 release date.
Still no open preorders for Hiera Glaphicos 6...
EDIT:
Is
this Fujimi Shobou's attempt at a Fantasy Senki title? 253 pages is pretty short though, especially compared to other Senki titles like MF Bunko J's Vanadis and Naga, or Famitsu Bunko's Gabriella Senki and Altiina.
