Harunobu Madarame

Harunobu Madarame

斑目晴信
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.
