It's revealed that Sega will hold a special stream to introduce Blade Arcus on November 21. The stream will be hosted by famous voice actress Asami Shimoda (Ami/Mami from Idolm@ster, Rin from Infinite Stratos) who voices Pairon. It will also feature Itabashi Zangief and Kami-chan who gave advices to the developers.
Note that this game didn't get much PR at launch (Nov. 5), most likely because Sega wants to push Dengeki Bunko Fighting Climax console launch (Nov. 13). So this's a very good news.
