At the end of the trailer, Asuna's voice actress says, " Gekijou-ban Sword Art Online: Progressive Hoshi Naki Yoru No Aria ," which translates to Sword Art Online The Movie: Starless Night Aria .
Voice actor Yoshitsugu Matsuoka is confirmed to voice Kirito , and Tomatsu Haruka will voice Asuna .
A-1 Pictures studio is therefore in charge of the animation.
Sword Art Online: Progressive then aims to retell the events of the Aincrad arc, but unlike the first season of the anime, Progressive does so by going step by step in more detail.
