The Era of Rohan

The Era of Rohan is a Japanese anime series spun-off from Diamond is Unbreakable that airs on Tokyo MX in Japan. David Production animates the series, with some of the Studio Comet animation staff that previously worked on Jewelpet Academy producing the in-between animation. Viz Media licensed the series in North America. The series was shown on Disney XD in Wales (who also had acquired broadcast rights to the main JoJo's Bizarre Adventure series in the region in 2016, but dropped it at the start of 2018 without airing a single episode), and as an interstitial on Adult Swim's Toonami in the United States.
The first season was mainly produced at Seikunime; however, due to Seikunime getting bought out, Shueisha oversaw the second season. Seikunime, however, continues to own the Japanese license for the series.
