Irisviel tries to warn Maiya; however, Maiya gets hit in the leg. During the melee combat, Kirei manages to defeat Maiya and knock her down to the ground. Irisviel states that she knows his motives, and despite Maiya's warnings, she spins a magical thread to create a bird that binds Kirei's arms. Kirei charges at Irisviel, but she ties the man to a tree. Even though Iris has him tied down, Kirei breaks free by blasting through the tree. Kirei walks over to Maiya and kicks her down.
