Elfman and Lisanna encounter Seilah of the Nine Demon Gates, who takes control of Elfman's body to strangle Lisanna. Makarov interrogates Michello, who tells them that Face is a pulse bomb used by the Magic Council to eradicate all magic on the continent; this would leave humans defenseless against Tartaros, whose curse power would be unaffected.
