The eleven-episode series was being released as a Blu-ray box set only that debuts on April 6th, 2022.
Funimation previously picked up the fall 2021 title from Science SARU with The Heike Story and now the Japanese home video release side is being dealt with.
We learned in late February 2022 that the box set was being pushed back to a June 15th, 2022 release date.
