Synopsis
Ryo joined the vehicle company Yaesu to follow in the footsteps of his missing friend, Masato. He became involved with the Makuhari test course, which Masato had also been a part of. The leader, Gray Gear, told Ryo, "If you want to know about Masato, come to the test course late at night and ride the new machine." When Ryo climbed into the new machine, the Vector Versus, and drove it around the course, he managed to exceed 300 kilometers per hour and suddenly warped into a mysterious space.
