Having suffered personal losses from the invasion, Takuto Kaneshiro joins the fight against the extraterrestrial enemies. In his quest for vengeance, the disillusioned young Takuto must seek out any possible allies, but the line between friend and foe is dangerously thin. When old powers crumble and new opportunities arise, many are prepared to capitalize on the chaos.
