Harunobu Madarame

Age: 19-23
Birthday: October 25, 1982
Zodiac sign: Scorpio
Blood type: O

The second president of Genshiken, Madarame is personally chosen by the first Genshiken president to be his successor, though Madarame shows the most leadership and initiative even before formally appointed as president.

He is a Gundam fan and arguably the most hardcore otaku out of all of Genshiken. Madarame buys dōjinshi without looking at price tags, something that occasionally leaves him with very little spending money on basic necessities such as food (his sushi of choice is bacon sushi topped with mayonnaise, cheap at 50 yen a piece).

Madarame takes pride in everything that he purchases. The Official Genshiken Data Book's otaku quiz section calls the highest level of otaku "Madarame."
