Chibita

The rival of the sextuplets. Although he is very short he is the same age as them. His most notable features are his big round eyes and the one strand of hair atop his bald head. His favorite food is oden. He is a very cheeky character who likes to laugh at people with his trademark laugh Kekeh (ケケッ). He loves to bully and humiliate the sextuplets (although they bully him back) and is terribly stubborn. However, he also has a childlike side to him and loves animals and flowers. His parents are never seen or mentioned and he lives with several cats and frogs.

There are many times when he appears as Iyami's assistant or subordinate, but he will also often be against Iyami. In his first appearance he was a very obedient child with strict parents, but soon became the bratty character he is now. In the 1988 anime he is portrayed as an edokko. Like Iyami, Chibita eventually stole the spotlight from the sextuplets and has become one of Akatsuka's most widely recognized characters. In "Osomatsu-kun Grows Up" he has become a clerk and is now 150 cm tall and has a full head of hair.
