Choromatsu Matsuno (松野チョロ松 Matsuno Choromatsu) is the third-born son of the sextuplets.


Kid sextuplet

Choromatsu as a child.

As a child, Choromatsu is described as "quick to judge and quick to flee." He is something of a coward, tending to watch from the sidelines, but he is nonetheless very confident in himself and his abilities. He is often described as "clever, yet selfish."

He gets along particularly well with Osomatsu, and the two often cause mischief together.

In one story, when Osomatsu let himself be adopted out by a rich couple, Choromatsu grew mad with power and took it upon himself to be the dominant one of the family, whipping his brothers and father. This was undone when Osomatsu returned and reclaimed his dominance.


Choromatsu is arguably the most logical of the six Matsuno brothers, and quite possibly be the only one truly concerned that they don't have jobs. He is the prominent straight man among his brothers. He often considers himself to be the most mature, going so far as to suggest that he should be the eldest brother and the one in charge, not Osomatsu. However, his biggest weakness is cute girls, particularly Nyaa and Totoko, in the presence in which he fawns over.

He is, however, not a particularly crafty or secretive person, and is not good at hiding his thoughts or emotions. He tends to overthink things.

In the commentary in episode 12, Osomatsu and Totoko remark about his serious and straight man nature not being his "true personality".
