It is Tokyo, Japan in the year 2017, just three years before the city's hosting of the 2020 Olympic Games. Throughout the city, the Shutoko metropolitan highway system is being dismantled and renovated, and new areas and facilities are being constructed, all at a feverish pace to complete the work in time for the Games. The Hyuga Corporation—a massive firm that succeeded in pioneering the practical use of artificial muscle fibers—is launching numerous products that supplement human muscle functions, and is in the midst of a massive surge in profits.

This was all a part of the company's plan to completely dominate their competitors and monopolize the industry. Dan Amo works at the General Affairs department of Hyuga Corp. By day, he is a nondescript salaryman, but at night, he relishes the sense of fulfillment his motorcycling lifestyle brings him.

A continuation of the first season. Makina lost consciousness when the Marishi Machina suit developed by the Hyuga Corporation seized control of her body and sent her charging onto the new Shutoko expressway on an MT-07. Luckily, Dan was able to stop her before it was too late. With Makina on the back of his MT-09 Street Rally, Dan began riding back towards the Genesis Café only to be intercepted by Hyuga Corporation chairman Mitsukuni Hyuga. He was waiting for them with an unsettling expression on his face. Dan was sure that he would be forced to resign his job for getting the heir to the company’s presidency, Kotaro Hyuga, involved in this mess. But when Makina confronts Mitsukuni about the truth behind the incident that claimed their parents’ lives, Dan is given an order he would never have expected. Dan keeps trying to avoid facing the trauma he experienced as a child, but is encouraged to find the truth by Makina. Sanae, the owner of the Genesis Café, seems to notice their troubled state and takes matters into her own hands. Can Dan face his past and free himself of the curse he has borne and reclaim his future with his own hands?
