The series was directed by Akiyuki Simbo based on the series composition by Kenichi Kanemaki based on the manga by Koji Kumeta.
Nozomi Entertainment has picked up a new property for release in 2020, presumably with Blu-ray, as they’ve announced the acquisition of the Sayonara, Zetsubou-Sensei series.
Details regarding the release and how much of the property they have between OVAs and TV will be forthcoming.
