Highs & Lows.While Twelve goes to rescue Lisa, Nine leaves to retrieve the plutonium. Meanwhile, Shibazaki and Hamura visit Souta Aoki, the former welfare minister, to question him about the Athena Project. Surprisingly, Aoki tells them everything about it; its connection to the members of the Rising Peace Academy; the experiments on the gifted children within the "Settlement"; and using drugs to artificially produce Savant syndrome. Aoki says that Five was the only child to have survived, however two other children, Nine and Twelve, managed to escape. He tells Shibazaki that the mastermind behind the project was Dr. Shunzo Mamiya, the politician who was behind Shibazaki's demotion. While Nine constructs the final bomb, Twelve reaches the amusement park and finds Lisa handcuffed on a Ferris wheel. Her body is laced with several bombs and a timer activates when the ride begins to move. Twelve comforts her and begins disarming the bombs one by one although they both realize that he cannot defuse them all in time. Twelve refuses to leave Lisa, and reluctantly tells Five the location of the plutonium in exchange for stopping the timer. Five cuts the power to the Ferris wheel, trapping Twelve and Lisa midair. Five reveals that she knows they stole a prototype atomic bomb rather than plutonium. The Metropolitan Police Department raid the school where Nine has just retrieved the bomb. Five orders him captured before she suddenly collapses.
