The Revolutionary leader Kuze manages to elude Section 9 once more. There's no time for Section 9 to recover though, because soon the threat of a nuclear weapon has the entire city of Nagasaki evacuated.

As the group from Section 9 works to prevent a nuclear explosion and unravel the truth behind these events, one random shot escalates the conflict to new heights!
