Mitsuo

Mitsuo (ミツオ), referred to as 'Mitsuo-kun' by most characters, is a second-year student at Sanada North High and a member of Class 2-A. He is well-known in the series for having really bad luck and being naive, yet kind.

History
In junior school, Mitsuo was extremely gullible and believed in many outlandish ideas. As a result, he became the subject of various notable incidents that are still laughed about even in high school. For example, Motoharu once switched his shoes with a girl's as a prank, but the two of them graduated elementary school without ever realizing it.

He also donned the mask of Rubber Shooter.

Appearance
Mitsuo is of an average height and build. He has messy dark brown hair and brown eyes, and is usually seen in the North High uniform.

Personality
Mitsuo is a kind-hearted and friendly boy. Despite the fact that others usually have fun at his expense, including insulting him in his presence, he is of a gentle disposition. Mitsuo is shown to get scared rather easily and is sometimes overly dramatic.

He is famous for being gullible and being unable to pick up on basic cues, and usually has very bad luck. As an example, he bravely jumped into a river, intending to save a cat floating in a box, only to find a stuffed cat inside. Afterwards, his friends note that it isn't even the first time he's leaped into the river.

Abilities
Mitsuo is very physically capable, having made it into the school rugby team's playing roster. In one instance, he knocks down Motoharu by accurately and forcefully throwing a marble (a stone in the manga) at him from several metres away. He also stands his ground and takes on Yoshitake and four others when they ambush him together.
