The new winter 2016 anime series will be getting a six-volume release that began on March 16th, 2016 where each release will be two episodes.
The home video release plans have been set previously by Japanese distributor Pony Canyon for Phantasy Star Online 2: The Animation and now we’re finishing off the cover artwork for it.
The bonus disc isn’t clear what’s on it but it does list it as a “sound benefit”, so it’s a soundtrack of some sort.
