Dragons reign terror over the earth, sea and sky. If sworn dragon hunters like Ragna are to have any hope of dealing death to these seemingly invincible, fire-breathing beasts, they must find a way to level the odds. Ragna teams up with a mysterious man named Crimson who has likewise sworn to stand against the dragons menacing the world. But although Crimson’s motivations may be mysterious, his goal and Ragna’s perfectly align, and together they’ll fight to vanquish the dragons once and for all.
