The remaining forces of the Solnoid and the Paranoid races now head toward Sigma Narse, a forgotten star system with a dying red giant for their final confrontation. The crew of five Solnoids who survived the battle at the ninth star system are sent to meet Capt. Nebulart, head of Intelligence, for what appears to be the last hope for both races.
When he was young, Arimasa Tsuchimikado rescued an injured cat and wished for it to become human. The cat, Kagetsu, is actually a member of the shape-shifting Kouga tribe and comes to live with Arimasa.
The war between Solnoids and Paranoids continues, but the conflict reaches a new height as both races complete their Planet Destroyers. This new technology wipes out several star systems leaving only the ninth star system undamaged. As both races head towards it, a Solnoid ship finds Lufy, an attacker cryogenically preserved inside an assault trooper among space debris. Reawakened, Lufy is invited to join a group of Solnoids who are set to complete the original secret mission of her former crew.
