Cybernetic Hi-School Part 2 ~Highway Buster!!~

Something strange is afoot in town. A midnight rider is assaulting drivers on the highway, bombarding them with tricky quiz questions. If the driver can't answer the questions, he and his car is blown up. Out of fear of the so-called Highway Buster, people dare no longer use the highways.

As a student at the Cybernetic Hi-School, the player is given the task by the headmaster of finding out who the Highway Buster is, and ultimately defeat him.
