Former Bosozoku Leader

The Former Bozozoku Leader (元暴走族リーダー, Moto bōzōzoku rīdā) is an old friend of Keisuke Takahashi, and the leader of a Bosozoku Gang.

Biography
After Ichijo lost to Takumi Fujiwara, the Tsuchisaka Lancer Evolution Team decided to call a group of gangsters to beat up Project D as a favor. Because of this, the rest of the members hid in their support vans, leaving Keisuke Takahashi to deal with them. Unbeknownst to them, the leader was one of Keisuke Takahashi's old friends, as he was once a member of a bosozoku gang before joining the Akagi RedSuns. As a result, for the humiliation, the gangsters threaten the Lan Evo team.

Trivia

 * In Funimation's release of Fourth Stage - Act 17 he is referred to as "Amada". This is likely an error, as the Japanese release does not call him this.
 * It is possible the name is copied from Masuo Amada, the voice actor for Aikawa.
