What was surprising about the first season to some degree was that there was no home video release, which does happen with some short form series. What happened, it turns out, is that the entire series was released to Blu-ray – but as a bundled exclusive with the seventh volume of the manga. The second season was bundled with the eighth volume of the manga that landed in March 2020. Now, the third season set is being released with the tenth volume of the manga that will arrive on May 27th, 2021 and will be priced at 6,160 yen as the previous volumes/bundles were.
