Three new cast members have been added to the upcoming Osomatsu-kun anime celebrating the 80th anniversary of the birth of "Gag Manga King" Fujio Akatsuka. Yōji Ueda (Jojo's Bizarre Adventure's Robert E.O. Speedwagon, Durarara's Kisuke Adabashi) will voice good-nature Dekapan, while Nobuo Tobita (Zeta Gundam's Kamille Bidan) is gluttonous Dayōn and Momoko Saitō is Hatabō, an otherwise normal boy with a flag stuck in his skull.
Other cast includes Takahiro Sakurai, Yuichi Nakamura, Hiroshi Kamiya, Jun Fukuyama, Daisuke Ono and Miyu Irino as the now grown-up sextuplets and Aya Endo as the series' heroine and childhood crush of the boys.
Kenichi Suzumura is Iyami, the flamboyant man who claims to be from France who immortalized a famous "Sheeeh!" pose and who stole the show from the titular sextuplets half-way through the original manga and in its second, 1988 adaptation.
Sachi Kokuryu is the sextuplets' rival/Iyami's assistant Chibita.
Gintama's Yoichi Fujita will be directing the Studio Pierrot production with Saint Young Men's Naoyuki Asano handling character designs.
