The film has now been slotted to a TBA category and will not make the September 10th, 2021 date that was planned in Japan.
The Japanese cast includes Shinichi Tsutsumi as Van, Ryōma Takeuchi as Hossal, and Anne Watanabe as Sae.
The two-volume series (which saw a slimmer four-volume run in 2017) came out in 2014 and won a couple of awards.
GKIDS previously announced their pickup of the North American rights to the film that’s part of the Annecy International Animation Festival 2021 showcase.
