The official website for the Mr. Osomatsu (Osomatsu-san) television anime began streaming a promotional video on Friday for the show's third season. The video previews AP's opening theme song "nice to NEET you!."
The anime will premiere on TV Tokyo, TV Osaka, and TV Aichi on October 12. The show will also air on AT-X on October 15.
Eiji Abiko, an animation director on the first season, is replacing Naoyuki Asano as the new season's character designer. Director Yichi Fujita and series script supervisor and writer Sh Matsubara are returning from the previous seasons at Studio Pierrot. Besides the sextuplets' voice actors, the other cast members are returning as well.
"Shuta Sueyoshi with TotokoNya & Matsuno-ka 6 Kydai" (6 Matsuno Brothers) are performing the ending theme song "Max Charm Faces ~Kanojo wa Saik!!!!!!~" (Max Charm Faces: Girls Are the Best!!!!!!). The voice cast members for the six Matsuno siblings and Totoko are performing the song with Sueyoshi (Spiritpact -Bond of the Underworld-). TECHNOBOYS PULCRAFT GREEN-FUND returned from the first anime season to compose and arrange the song and provide lyrics.
The Mr. Osomatsu television anime is inspired by Fujio Akatsuka's original Osomatsu-kun manga and "high tension comedy" TV anime, which centers on the Matsuno household with six naughty and mischievous sons (who are sextuplets). All of the sextuplets, including the eldest Osomatsu, are all in love with the same girl, Totoko. The original Osomatsu-kun series followed the family when the sons were 10 years old. Mr. Osomatsu re-imagines the original manga and TV anime with the sextuplets as adults.
The first Mr. Osomatsu anime season premiered in October 2015, and Crunchyroll streamed the series as it aired in Japan. The second Mr. Osomatsu anime season premiered in Japan on TV Tokyo and TV Aichi in October 2017. The series also inspired a film and various videos.
Viz Media acquired the digital streaming, electronic sell-through, home video, and merchandise rights for the Mr. Osomatsu anime, including the second season. Viz Media is releasing the anime with an English dub.
