Plot
Roughly a millennium before the beginning of the series, humanity had waged a war against mysterious beings in another world. In the present, a boy named Toshizo Shiryo, his twin sister Yumika and his childhood friend Minoru Araki reside in a remote village in the island nation of Hinomoto; but their peace is abruptly interrupted when an unusual 400-meter tall kaiju attacks the village along with an army of unknown origins, and Toshi loses his mother in the resulting devastation. He vows revenge against the enemy and later enlists in the Strategic Defence Coalition Expeditionary Force, accompanied by both Yumika and Minoru.

As the story progresses, more mysteries surrounding the true origin and nature of the enemy, as well as the untold history of the world are addressed, and the reader gradually discovers that the war's origins may not be so linear. Toshi and the Rangers find themselves as the only remaining hope for the world, as they fight to uncover secrets from the past and stop the forces that want to bring about the destruction of mankind.
