Osomatsu

Matsuno (松野おそ松 Matsuno Osomatsu) is the titular character of the series Osomatsu-kun. He is the eldest of the sextuplets and acts as the leader, though he may not always necessarily be the actual protagonist of stories (with that role going to Iyami or Chibita at times instead).

His name derives from the word お粗末 (osomatsu), meaning "poor" and/or "lousy".

An older version of the character also appears as the titular protagonist in the 2015~ spin-off titled Osomatsu-san.

Child (-kun)

Appearance:

The younger Osomatsu generally appears as a young boy who wears his hair short in an old-fashioned style, with the fringe either swept to the side or more often depicted as a bowl-cut from later head-on views. The hair has two curled strands in the back, as cowlicks.

In the initial frontispiece for the manga, he was depicted with more of a larger snubbed nose, freckles, and a long mouth, but these facial features were quickly altered for the actual comic (although the freckles would still appear in some other early frontispieces). His more iconic features include larger eyes that are set closer together, a smaller rounded nose, and a mouth not as set to the side.

He is most often seen wearing a three-buttoned uniform coat with a white collar, lighter-colored pants, and running shoes. In summer chapters, he wears a lighter, short-sleeved shirt with dark shorts; these colors are swapped around to match the winter outfit in the 1988 Pierrot anime.

In both the manga as well as anime adaptations, Osomatsu's height varies from reflecting how he is relatively tall for his age (150cm) and slim (46kg) but strongly built, to him being much shorter and chubbier of a child. The 1988 show in particular infamously depicts him and the others much smaller as the series goes on, due to the overall art shift.

Osomatsu tends to have the most trouble with his teeth, being stated to have at least three cavities in an official profile as well as once actually depicted with such teeth in horrid condition for a specific chapter setting, which helps in visually differentiating him from the others. It is such that in one of those in-manga occasions ("Four Stories with the Theme of Teeth"), he had his aching teeth knocked out, but only wound up with more decay when he continued to keep eating candy.
