One day, he accidentally stumbles into his dad's secret research and discovers an E5 bullet train. There he learns his father is part of an organization called "Shinkansen Ultra Evolution Institute" (SUEI) and is one of the project developers to build transformable bullet-train robots called Shinkalion, in order to combat the mysterious enemy called the Bachigami and protect the safety and peace of Japan.
