The Osomatsu-kun anime celebrating the 80th anniversary of the birth of "Gag Manga King" Fujio Akatsuka has introduced the casting for the two characters who steal the show from the titular sextuplets half-way through the original manga and in its second, 1988 adaptation. 

Kenichi Suzumura (Gintama's Okita Sougo) is Iyami, the flamboyant man who claims to be from France who immortalized a famous "Sheeeh!" pose.

Sachi Kokuryu (Gundam Build Figher's Reiji) 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.

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.
