The central plot arc concerns the true nature of US–Japan relations. After a volley of two hundred intercontinental ballistic missiles are fired at Japan, the US government contracts the killer7 to eliminate Toru Fukushima (Jim Ward), the head of the UN Party. However, an assassin posing as Fukushima's secretary kills him first in an attempt to reclaim the Yakumo document for the Liberal Party, believing its wisdom would help the party to regain political power. Shortly thereafter, Kenjiro "Matsuken" Matsuoka (Steve Blum) kills two senior members of the UN Party to become its new leader, under the influence of Kun Lan. In the end, the killer7 defeat the two UN Party members who had been reanimated by Kun Lan as Japan is destroyed by the missiles.
