Ah, Hozuki no Reitetsu. The series that shows even Hell can be a better place, or worse place depending on where you stand. Anyway, a brief trailer has been released showcasing an OAD (Original Animation DVD) set to be included with Volumes 17-19 of the manga. Images have also been released showing some of the new characters who will join the colourful cast of Hell on their additional adventure.
