Noboru Yamaguchi

The leader of Destrade High School's first-year students. He has the nickname of "The Unsinkable Battleship", which is coincidentally the nickname of professional wrestler Stan Hansen who is extremely popular in Japan, and is mentioned to be a member of a bike gang called "Earth, Wind, Fire, and Water" in his spare time. ("Ash, Wind, Fire" in Japan; both are parodies of an American Funk band Earth, Wind & Fire.) His cronies believe that he hates jokes, since he's always so serious. In truth, he is a connoisseur of sophisticated humor, despising the sophomoric jokes that his friends prefer. He is also a postcard comedian (someone who sends jokes in the mail to be heard on the radio). His pen name is "Ajishio Taro" (roughly, "Salt Boy"), and he is rivalled only by Kamiyama, who he initially knows only as "Honey Boy." He is easily recognized by his large afro hairstyle and his ever-constant sunglasses
