Kancho-kun is a tiny pink creature with hands on his head. He has no facial features except two dots for eyes, and two flat, rectangular feet. His main attack is firing his fingers up an opponent's rear-end, a prank commonly performed by small children called a "kancho" (hence his name). He has four jet pipe's on his sides to help launch him towards his opponent's posterior.


The main personality trait Kancho-kun has displayed is his determination to "kancho" people, which is his only life goal. He has also shown assertiveness, immediately nominating himself as the de-facto leader of the rebellion against the Reverse Maruhage Empire.


The Former Maruhage Empire

As Tokoro Tennosuke watches Don Patch subject Ishikawa Goemon to torture over his revealed identity, Kancho-kun arrives in Life or Death Triple's Hell Area, after being summoned by Rububa the Bubbles. Kancho-kun immediately notices Tennosuke and strikes from behind by propelling himself into his rear-end, launching him into the Heaven Area. When Bo-bobo notices Kancho-kun stuck to Tennosuke's rear-end and pulls it out, Tennosuke prepares to attack it, only to find out that it's "dead".

According to the narrator, Kancho-kun puts all of its energy into one single attack. Because it can only deliver one kancho in its lifetime, it dies shortly after.

The Playoffs and the Reverse Maruhage Empire

Despite being dead, Kancho-kun isshown to be alivel during the threat of the Reverse Maruhage Empire, and becomes de-facto leader of the group as they journey through the Yamiking towards Hydrate. He hardly assists the rebels at all, until they come face-to-face with the mad leader himself, where he lands many painful kancho blows against Hydrate's rear-end (but dies multiple times). After the Reverse Maruhage Empire falls, Kancho-kun disappears without explanation.

Shinsetsu Bobobo-bo Bo-bobo

Kancho finally returns to the series when the rebels are fighting Tsuru Tsurulina III. Though he fails to kill him, he was able to land a powerful blow against his former leader. He once again dies, but now permanently.

In the final chapter of the series, Don Patch arrives at a graveyard, where several Kancho gathered for the funeral of the third-era Y-Block leader who had assisted the rebels in the final battle. Don Patch takes another one from the crowd at the funeral before moving along.
