12 of the main voice cast members for the Mr. Osomatsu television anime appeared at the two-session special event "Fes Matsu-san '16" at Chiba's Makuhari Messe center on Sunday. The event announced two more event projects this year, but did not announce a new anime season.

The "Haru no Matsu no Ichi" merchandise campaign from early April will come back as "Haru no Matsu no Ichi Returns" with new goods in early June in Osaka. The second announced event project is a "massive exhibition" with displays and merchandise that will travel to major cities throughout Japan starting this summer.

About 13,000 fans attended the two sessions of Sunday's "Fes Matsu-san '16" in person, and theaters throughout Japan streamed the event live. Between the audiences at the Makuhari Messe center and audiences at theaters nationwide, about 70,000 people saw the event live.

Fujio Akatsuka's original Osomatsu-kun manga and "high tension comedy" television anime from the 1960s centered on the Matsuno household, which has 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 series followed the family when the sons were 10 years old.

The new Mr. Osomatsu show re-imagines the original manga and TV anime with the sextuplets as adults. The series premiered last October, and Crunchyroll streamed the series as it airs in Japan. The anime's second cour (quarter of a year) premiered on January 4 and ended in March. The series is inspiring a text novel, a smartphone game, and three PC browser games.

Takayuki Hirobe, TV Tokyo's project planner of the anime, said in an interview published in January, "We originally planned on making two cours, but we haven't said, 'It'll end after two cours.'"
