Sousuke is sent to Helmajistan after Gauron is found to be alive. He is temporarily assigned to an AS squad from Mithril's Indian Ocean corps in a mission to kill Gauron, but because of his young age, his presence is met with derision. They ignore Sousuke's advice and their first encounter with Gauron ends in disaster. They also commandeer a nuclear-armed ballistic missile Gauron was planning to sell on the black market.
