Mr. Osomatsu 2nd season

The third season of Osomatsu-san.

The Matsuno sextuplets (leader Osomatsu, wannabe tough guy Karamatsu, straight man Choromatsu, cynical Ichimatsu, cheerfully stupid Jyushimatsu and lovable spoiled Todomatsu) are now in their 20s, still living together in the same house as NEETs. Their neighbors still include such eccentric characters as fish market idol Totoko, loud bucktoothed troublemaker Iyami, tiny rival Chiba, wacky inventor Dekapan, and giant mouthed glutton Dayon. Join the Matsuno siblings as they overcome mundane hurdles in their daily lives, such as finding employment, figure out who should pay the bar bill, and who should get the extra pastry!

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.

Of course, limiting the fun to a four-way might get a little stale; although the group still messes around with the Judo Club and the Newspaper Club, more girls have come to get in on the excitement. Takatoshi's sister Kotomi, a new student at Ousai, is
