The founder and leader of the Sket-dan, nicknamed Bossun (ボッスン). When he puts on his goggles he is able to be in full concentration and saves the day. When talking about his special traits, the sket-dan tends to break the fourth wall, saying how he has nothing unique for a shounen main character. He is an amazing artist and has a bunch of expressions that are easy to read.

He is determined to help his clients and will do it to the best of his abilities. Whenever the sket-dan realizes that Bossun isn't needed he goes into a lazy, depressed state.
