The feature anime film adapting the 1985 novel Our Seven-Day War made its December 13th, 2019 debut without a problem and the home video release side was set up recently.
Sadly, no English subtitles are included and it looks like the set comes with just a booklet and the previews for the film.
The DVD is priced at 3,800 yen while the Blu-ray is priced at 4,800 yen.
