It reminds me of a similar scene in the Japanese movie Virus in which a bio-weapon (US made, of course) gets loose and wipes out most of the human race the Chairman of the Joint Chiefs activates an auto-launch system that winds up nuking most of the cities of the world. The reason for launching nukes isn't that clear. Takashi gets a little Matrix-y for his zombie killing.The scenes in Air Force One are neat, if a little odd.
Takashi grows to love his shotgun, after Kohta tells him how to use it effectively. Rei is tossed off the roof of the Hummvee. Cue a 28 Days Later musical montage homage! Of course, the group runs into zombies (this is not High School of Peacefully Driving Around) and encounters a barrier across the road. The city appears to be deserted, although there are signs of violence. The group decides to head to Saya's house first, since it is the closest. The girls get dressed (Why? Why?!?!?!), Kohta dubs the dog "Zero" after the World War Two fighter (of course), and Takashi gets a shotgun.
Among other things, we learn that Saeko sucks her thumb when she sleeps and that Kohta likes sing abut shooting guns to the tune of "Row Your Boat.". The girls looking fashionable and ready for some zombie-killing.While Zombie President is getting ready to nuke Russia and China (wouldn't that just create radioactive zombies? Sequel!) back in Japan our heroes are driving across the river to the part of the city their families live in.
