The killer cuts down player after player, and Ryouta soon discovers that he has fallen into the villain's clutches, only to escape by the skin of his teeth! As the curtain falls on the battle of wits between Ryouta and the murderer, another rises on the most ferocious fight the Sanctuary has ever witnessed!!
