Фуджімото Кіїчі

The leader of Manuel High School's first-year students. At school, he is a ruthless brawler who likes to use aggressive ways to solve problems. But at home, he is a very generous Internet user with a deep concern for netiquette. He also runs a web page/blog/forum that he frequently posts in. His polite behavior on the net, and his answering to "The Troll" (Cromartie High student Tanaka), eventually leads to the humiliating branding of Fujimoto as a shut-in (hikkikomori in Japanese).
