The anime will depict the lively everyday lives of the demon brothers through special episodes separate from the game’s main story (Lessons).

Animation studio Gainax presented a website for the release of a movie adaptation of the Tengen Toppa Gurren Lagann TV series in the fall of 2008. Both the original director and series script editor will return to work on the new project. Gainax will also be hosting four events to celebrate this occasion at this year's Tokyo International Anime Fair, featuring voice actors from the anime.

Someday a group of classmates will perform a charm at night after school—the Happy Sachiko charm. This paper doll ritual is meant to make them stay friends forever, but performing it incorrectly will lead them to be dragged down into a dilapidated phantom of Tenjin Elementary School, which had been torn down years ago. Trapped until they can reunite and perform the charm correctly, the students will have to solve the mystery of the haunted school in order to make it out alive. Before that ill-fated event, however, the friends led ordinary lives. Corpse Party: Missing Footage reveals an insight into the students' lives on the day before they were thrust into a waking nightmare. [Written by MAL Rewrite]
