The leader of Sket-dan, also known as Bossun, uses goggles to focus intensely and save the day. Although the group often jokes about his lack of unique traits as a shounen protagonist, Bossun is an exceptional artist with easily recognizable facial expressions. He is highly dedicated to assisting his clients to the best of his ability. When he realizes that his skills are not needed, Bossun can become lethargic and downcast.
