One day, a young boy with blonde hair appeared from the other side of the castle walls. His name was Flynn Scifo, and his voice was cold and firm when he said, “this has nothing to do with me…” This is how the two young boys met—one who never held a sword before, and another who lost his sword, as the two collided, and stirred up the Lower Quarter. As the world continued to spread out for the two, there was a wall of reality that stood in their way. Just how did the two overcome this obstacle?
