According to an old tradition, with the resurrection of the Demon God, the Goddess of Fate will choose six heroes—the Braves of the Six Flowers—and grant them strength to stand up against the fiends aiming to transform the world into a living hell. Adlet Mayer, the self-proclaimed "Strongest Man in the World," has come in Piena with the hopes of becoming a Brave. Despite the fact that things don't go as planned, Adlet is eventually picked as one of the six heroes shortly after being visited by Nashetania Loei Piena Augustra, crown princess and fellow Brave.
