The Testament of Sister New Devil Loli Ero Succubus Maria no Characommentary Tsuki Hizou Eizou

The Testament of Sister New Devil Loli Ero Succubus Maria no Characommentary Tsuki Hizou Eizou was produced by Studio IMS as a supplemental home video release in 2015. It was created to accompany the anime adaptation of Tetsuto Uesu's light novel series, functioning as an 'omake' or bonus visual content that focuses on the character Maria Naruse. The production reflects the mid-2010s trend of packaging exclusive behind-the-scenes character commentary and short animations within limited-edition box sets to incentivize physical media purchases among dedicated fans of the ecchi genre.

The design and artistic direction were overseen by the studio’s animation team, which aimed to lean heavily into the stylized, fan-service-oriented aesthetic established in the main television series. By providing character-specific commentary and archival footage, the release sought to deepen audience engagement with the source material's character designs. While the series itself received a polarized critical reception for its intense focus on fan service, this specific item remains a distinct artifact of the studio's broader efforts to expand the franchise's transmedia footprint.
