Max Maniacs

Max Maniacs was Tokyo's biggest biker gang before it took on the Haitani Brothers.

History
For unknown reasons, the two leaders of Max Maniacs fought against the Haitani Brothers and lost. According to Izana Kurokawa, Ran Haitani took down its leader in one hit and interrupted the fight between his younger brother Rindo Haitani and Max Maniacs' Vice-Leader. Rindo allegedly pinned him down as Ran repeatedly bashed his face. The Roppongi Hai-Manic War ended with the Vice-Leader's hospitalization and eventually, demise.
