In a distant star system, the Alliance faces a turning point after fierce clashes with the Shadows. Having repelled a counterattack at the ruins, the Alliance rises like a phoenix from the ashes. A mysterious crystal revolutionizes research, and the Star Energy Fusion Matrix powers up warships and infantry gear, sending their strength soaring. The intelligence bureau uses captured technology to crack the Shadows’ Sniffer Network through reverse engineering, giving them control over enemy movements. The military devises a Three-Ring Defense System, whose power is proven in war games. Though the remnants of the Shadows lie low at the frontier and collude with pirates to raid the border, an Alliance task force strikes back, uncovers vital intelligence, and continues to strengthen the defenses in preparation for the final battle, determined to safeguard peace in the universe.
