Madarame, Harunobu

斑目晴信

Madarame, the second president of Genshiken, is personally selected by the first president to be his successor, although Madarame demonstrates the most leadership and initiative even before being formally appointed as president.
He is a Gundam fan and arguably the most hardcore otaku among all members of Genshiken. Madarame buys dōjinshi without checking price tags, a habit that occasionally leaves him with very little spending money for basic necessities such as food (his preferred sushi is bacon sushi topped with mayonnaise, costing a cheap 50 yen per piece).
Madarame takes pride in everything he purchases. The otaku quiz section of the Official Genshiken Data Book refers to the highest level of otaku as "Madarame."
