Shinkansen Henkei Robo Shinkalion Z the Animation

Shinkansen trains became the basis for the Shinkalion robots created to protect Japan from mysterious giant beings. As the threat returns, the Ultra Evolution Institute develops a new generation called Shinkalion Z, supported by Zailiner vehicles that transform from conventional trains into additional weapon systems. Shin Arata, a boy fascinated by strange phenomena, becomes one of the young drivers capable of operating these machines and meets Abuto Usui, whose knowledge and abilities complement his own. With unknown enemies appearing and new mysteries spreading along the rail network, the two boys are drawn into an adventure combining trains, transforming robots, and a search for the truth behind the danger now facing the country.
