The Library team discovers that the I-Jin have built a rocket which, when launched, will play the supposed "Death Symphony" over worldwide radio frequencies. A fleet of US Navy ships are ordered to destroy the base, which is in the middle of the Pacific Ocean, but the warships are sunk by the base's weapons. Nancy is revealed to be a double agent, and escapes to the I-Jin Base. Yomiko becomes bent on finding her, even though she turned on the Library Team, but she is taken hostage herself by none other than Nancy, revealing that she is an I-Jin clone of Mata Hari. Yomiko is imprisoned in a machine room within the I-Jin base, but when Ikkyu asks her to join the I-Jin, she refuses. Ikkyu reveals his plans to Yomiko, and then seemingly kills Nancy before her eyes. As Yomiko watches in horror, another Nancy steps out of the shadows and kisses Ikkyu passionately. The lovers depart, leaving Yomiko to die in the rapidly flooding room.
