Shinkansen Henkei Robo Shinkalion: THE ANIMATION - S02

To defend Japan from the threat of mysterious giant monsters known as "Giant Monstrous Beings," the Shinkansen Ultra Evolution Institute created the "Shinkansen Transformable Robot Shinkalions." Now, facing new enemies, the institute is developing an advanced robot called "Shinkalion Z" and specialized armored vehicles called "Zailiners," which transform from regular trains to enhance the robot's power. A group of children with high compatibility rates are chosen as pilots for the "Shinkalion Z," teaming up with the institute's staff to battle the returning monsters. Amid this struggle, unknown enemies appear-and two boys cross paths.
