Panty & Stocking in Sanitary Box! This special episode/short is going to be included in the 5th DVD/BD volume release , which is expected to be released in April 28
(or April 22? Gainax's official weblog claims the release date is April 22, however, the official shop claims the release date for said DVD/BD volume is April 28, so I'm not quite sure which source is actually right). Nevermind, the official release date is APRIL 28.
Anyway, here are some sneakpeaks!
