- DVD Commentary: Funimation provides a commentary for episode 2, with J. Michael Tatum (the ADR director, plus the voice of Ihika), Colleen Clinkenbeard (Rin), Jamie Marchi (Mimi) and Robert McCollum (Kouki). It has a "titular" pun and random profanity ("Fuck!" "Oh dear.") before the opening credits are even over, and continues on from there.
