Story
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.
