Energetic Explosion Ganbaruger

Three boys-Kotaro, a ninja in training; Rikiya, an aspiring baseball player; and Yosuke, a studious scholar-lived ordinary lives in Aozora Village. One day, Kotaro and his father, Tobe, accidentally shattered the seal separating the Underworld from the Human World. Soon after, the warrior of light, Eldran, appeared before Kotaro, Rikiya, and Yosuke, accompanied by three mysterious machines. The boys were chosen as the Ganba Team, tasked with saving the world from destruction by piloting the robot Ganbaruger.
