Among them are Yusuke Amamiya, Joh Ohara and Megumi Misaki who with Takuji Yano and Mari Aikawa sought to create a suit strong enough for space exploration.

However, three of their classmates and friends Kenji Tsukigata, Rui Senda, and Goh Omura felt their talents were being wasted and leave to join an evil organization called Volt who offers to raise their full scientific potential.

As a result, when Yusuke and company saw them leaving, Kenji draws a gun on the three with Takuji and Mari taking the fatal blow.

And then in 1988, the present day, with Kenji, Rui, and Goh now known as Doctors Kemp, Mazenda and Obular, Volt begins its attack by devastating Academia Island.

Soon after, the Livemen are joined by Tetsuya and Jun-ichi, the respective younger brothers of Takuji and Mari, while learning that there is a darker agenda behind Volt that only its leader Bias knows.
