He becomes embroiled in an incident during which he pulls out a holy sword imbedded
in a rock and ends up becoming a "Shepherd," one who casts away calamity from the world.
He begins to realize the gravity of his mission, and his dream of coexistence between mankind and
the seraph becomes more intense—
And thus, the Shepherd embarks on an amazing journey with his companions.
