After Ichijo lost to Takumi Fujiwara, the Tsuchisaka Lan Evo 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, however, it is revealed that the leader, Amada, was one of Keisuke Takahashi's friends, as he was once a member of a bosozoku gang before joining the Akagi RedSuns. As a result, for the humiliation, the gangsters began to turn their backs against the Lan Evo team.
