Appearance is part of collaboration between anime franchises

The official websites for both Black Clover and the Eiga no Osomatsu-san anime film announced on Monday that both anime are launching a collaboration campaign. The campaign debuted with a visual (seen below), as well as a featured "appearance" by the Matsuno sextuplets in the Black Clover anime's 76th episode "Madōshi X" (Magic Knight X), which will premiere on TV Tokyo on March 26 (on BS TV Tokyo on March 29).

The Eiga no Osomatsu-san film opened in Japan on Friday . The film centers on the sextuplets at a high school class reunion. There, they see all their former classmates who have become "proper" adults with company jobs. The sextuplets sulk about this and go home and drink until they fall asleep. But when they wake up, a certain scene awaits them.

The Black Clover anime premiered in Japan in October 2017. The show was originally listed with 51 episodes, but it continued into a new season with episode 52 last October. Crunchyroll is streaming the series in Japanese with English subtitles, and Funimation is streaming the show's English dub . The show debuted on Adult Swim 's Toonami programming block in December 2017.
