Centers around the titular character, a small boy who gets into different situations with those around him. Each strip is done in four vertical panels in two rows (eight panels in all), read from right to left. The presence of Akatsuka's "Star System" concept is prominent especially in the later strips, as some notable characters are added into Ken-chan's supporting cast. The work proved to be a challenge for Akatsuka, who was restricted from depicting children committing bad acts that wouldn't be punished, or having them be rude or fight in general.

A Spin off of Osomatsu-kun (Or more aptly, the shorter "Akatsuka-kun Can Do Anything" that was later renamed "$-Chan and Chibita", a series with a somewhat similar premise.) starring the titular Chibita. Much like in Osomatsu, chibita's familial situation as well as other factors, such as setting can change in each self contained gag story. Iyami appears from time to time as well as other Akatsuka characters, such as "Mojamoja-ojichan", whom was the protagonist of his own comic, this time appearing here twice as a sort of father figure/mentor for chibita.

This series revolves around a rather dumb young man named Bokeo, his super-smart cat Tora, and the situations that they get into. Fujio Pro describes Bokeo himself as being a predecessor to Bakabon, and that the series was the first work by Akatsuka to feature such a foolish protagonist (while it is said that the presence and popularity of Ichiro in Otasuke-kun paved the way to have a fool character as the spotlight).
