While doing so, Yuji receives an unexpected letter from Father Steyl, giving him a convenient cover story for the extraordinarily powerful spell he'll need to wipe out the monsters and protect the precious fertilizer, Mother Earth's Tears. But will his magic be enough to dispel the curse that shrouds the island?
