The cover of the first BD release (out November 11th) was revealed today on the show's
official website. Very appropriate for the first two episodes.
The first press of the BD edition will include the show's first soundtrack album, which includes the opening music and a TV size version of the ED, "Wareta Ringo" (Broken Apple) by Risa Taneda.
Special features include all 3 PVs for the show, plus all the "Preludes" (the various interviews and behind the scenes featurettes) and the "Chronicle" behind the scenes special that was shown on TV.
