Two months ago, Nathan Grant was thrown into the world of Alchemic Warriors and the flesh-eating Homunculi they hunt. His mentor, Astrid Rachelle, left him to go back to his life with his friends and sister... who think he's the Starlight Lancer, defending the town from evildoers. Then Astrid comes back into his life with a new mission: find and destroy the League of Extraordinary Elects, a Homunculus society with a plot to annihilate all of humanity. Now Nathan has to make a choice: relinquish the Arms Alchemy, and risk a catastrophic enemy victory... Or abandon his normal life, follow the Path of a Hero, and truly become the Starlight Lancer.
