Although the Lances of Betrayal were thought to have fallen, they return and begin forming a powerful army on the frontier. They pillage the towns, ravage the lands, and become the object of fear within the empire. Only a young man named "Koinzell", holder of the "Black Blade", has the power to annihilate these "Lances of Betrayal" alone. Who is Koinzell? What is the object of his journey? Where did he come from? Could he be connected to the "Seven Heroes"?
... Is 'protection' the only reason that Haruka approached Mamoru? Or could it be something else?
