Attendees of the Neoromance 「ア・ブ・ナ・イ❤ネオロマンス」 event will be able to view actual game play from the upcoming Octave game.
This will happen only at the Sunday (January 20) show in the venue lobby from 13:00-19:00, except during the event pre-opening/opening times.
There will be a limited number of double-sided postcards given out to viewers. (See above for image).
