The official site for the upcoming original series Seiren has updated again with TBS Animation bringing out a new 50-second promotional spot for the show.
The show is set to be directed by Tomoki Kobayashi based on the series composition from Kisai Takayama, who also did the original character designs.
It works as a bit of a clip before going into a montage of sequences set to the opening theme song from it while highlighting the premiere schedule and the upcoming CD release.
