Ep. 3: Shibazaki joins the investigation team while Nine confirms police awareness of plutonium theft.

Shibazaki transfers to the lead police agency, causing dissatisfaction among staff. Nine deduces that counter-nuclear terrorism special forces indicate the police know about the plutonium theft from the Aomori nuclear facility by him and Twelve, planning to verify this through further attacks. Shibazaki speaks with Kurahashi and learns that one plutonium thief worked briefly at the facility and had his identity erased. He shares his dislike of summer as a Hiroshima native due to older residents' fears from the World War II atomic bombing. Nine and Twelve send a third video with an Oedipus Rex riddle. Lisa runs away from her mentally unstable mother. The police broadcast Shibazaki’s live stream nationwide, revealing the bomb’s location and challenging Nine and Twelve before cutting the feed. Observing hazmat suits in footage, Nine confirms the police linked them to the stolen plutonium. Kurahashi explains Shibazaki’s demotion as he notes the hot weather.
