Every three hundred years, the awakening of the Evil God heralds destruction and despair. To avert this fate, the Spirit of Fate selects heroes known as the Braves of the Six Flowers, marking them with a crest as the world's saviors. There are invariably six heroes—but on this occasion, seven individuals gather when the chosen convene. Adlet Mayer, who calls himself the "strongest man in the world," is one of the seven Braves. The group also includes the first princess Nashetania Loei Piena Augustra, the loyal knight Goldov Auora, the feline-like assassin Hans Humpty, the childish yet deadly Chamo Rosso, the stern Mora Chester, and the loner Fremy Speeddraw. Although all appear to be likely candidates for the title of Brave, there is only one explanation for the extra hero: the seventh is an infiltrator seeking to sabotage their mission and tear the Braves apart from within. With all evidence pointing to him, Adlet becomes the prime suspect and finds himself on the run, desperately trying to prove his innocence. However, as time runs out and the Braves turn against one another, the Evil God's minions wait restlessly for its return.
