Shionne is afflicted with a curse that hurts anyone who touches her. While evading their pursuers, the slave pulls a blazing from the Master Core in Shionne's possession and uses it to repel the Renan forces. As only Iron Mask can wield the due to his inability to sense pain, he and Shionne form an alliance to take down the five Lords and gather the other Master Cores they possess. With help from the Crimson Crows, the pair confront and defeat Calaglia's Lord, Balseph. In the occasion, the slave's mask partially breaks and he remembers his name, "Alphen". After liberating Calaglia, Alphen, Shionne and the Crimson Crows' leader Zephyr depart to the realm of Cyslodia, guided by Rinwell, a mage and member of the Silver . Once arriving there, Zephyr is captured by agents serving the local Lord Ganabelt Valkyris, led by Zephyr's son Law. Having a change of heart once his father is sentenced to a public execution, Law assists Alphen and the others in an attempt to rescue Zephyr who ends up being killed by Ganabelt himself. Law joins Alphen, Shionne and Rinwell to avenge his father and they confront and kill Ganabelt.
