The latest comes in the form of this new video from Aniplus Asia, who will be streaming the series in their territories.
What we get here is a nearly three-minute promotional video with English subtitles looking at the series proper ahead of its October 7th, 2017 debut there.
Takahiro Harada is directing it with Miyuki Kuroki based on the series composition by Yuniko Ayana and Yukie Sugawara.
