Thomas Romain, the art setting designer for the Senki Zesshō Symphogear franchise and many other works from the studio Satelight, reported on Twitter on Friday:

Symphogear GX is the best selling anime of the summer season in Japan! Which means... Symphogear will come back again! Thank you! — ThomasRomain ロマン・トマ (@Thomasintokyo) November 26, 2015

Romain had previously indicated in Japanese on Thursday that Symphogear GX topped sales charts among summer anime and added that he "looks forward to what will come next":

The franchise premiered with a 13-episode television series in January 2012. The third Symphogear television anime, Senki Zesshō Symphogear GX, aired from July to September.
