A friend vanishes into a test course, and the only way to find him is to push a machine past its limits into somewhere that shouldn't exist. The Vector Versus doesn't just go fast, it breaks through into a space that rewrites what "racing" means. Two episodes that treat a disappeared person like a genuine mystery instead of setup, and a mecha that feels like discovery rather than spectacle.

Ryo takes a job at the vehicle company Yaesu so he can trace the steps of his friend Masato, who has gone missing. The work brings him to the Makuhari test course, where Masato was also involved. Gray Gear, who leads the group, tells Ryo that if he wants answers about Masato, he should come to the course late at night and drive the new machine, the Vector Versus. Ryo takes it around the track, pushes it past 300 kilometers per hour, and is suddenly warped into a mysterious space. The two-episode OVA mixes mecha action with science fiction.
