Naoto Nakashima

Hayato Hayasugi (his last name is a pun on the words for "too fast") and other children will serve as conductors to pilot the Shinkalion. The Shinkalion robots are various models of real-life Japanese bullet trains (shinkansen) that transform into robots to fight an unknown evil to protect the safety and peace of Japan. The children must work together with the adults of the Shinkansen Ultra Evolution Institute (SUEI) to defeat a monster that looks like a jet black bullet train.

It was just a usual morning. Akira Shiroyanagi, a high schooler who loves games and Konpeito (Japanese sweets), has suddenly been dragged into a battlefield by a mysterious girl who calls herself Mion. The participants are told that they are "erased from the family register, involved in an experiment, and gained certain powers." Akira is determined to win the game with his newfound powers and destroy the organization. Armed with a power no one expects and his "brain" skills, the new period of intelligence battle begins!
