A cruiser yacht, with all aboard mummified, is discovered drifting out at sea. Toma and Sebumi suddenly face a series of spec-holders controlled by a mysterious ‘Ninomae’, who turns out to be Toma’s younger brother...except that he’s supposed to be dead. Ninomae tries to enlist Toma among the specs using whom he plans world domination, but she refuses, saying she wants to live a normal life. Cursing Toma for getting him into this, Sebumi nonetheless does his utmost to protect her. Toma’s left arm is in a cast: what is she hiding there? The case grows in scale, eventually involving the government. What is the ‘simple plan’ going on behind the scenes? And what is the course of the future traced out by the person who recorded ‘the Third Prophecy of Fatima’?
