Getting published by Squeenix, being released 02.18.16 in Japan for PS4 and Vita.

ATB is back, character's have beautiful designs, and don't even get me started on the music we have been teased with already.
It almost seems like an Chrono Trigger or Legend of Heroes spiritual sequel to me, overall it looks just absolutely gorgeous.
Music almost reminds me of Leene's square theme.
