In 2020, a large creature rampages through Tokyo, destroying everything in its path. In 1959, Asa Asada, a spunky young girl from a huge family in Nagoya, is kidnapped for ransom--and not a soul notices. When a typhoon hits Nagoya, Asa and her kidnapper must work together to survive. But there's more to her kidnapper and this storm than meets the eye.

The mysterious creature appears in Tokyo Bay and takes a chunk out of a self-defense forces vessel. Asa is called into action, but she has trouble reaching the airfield due to the Olympic crowds. Meanwhile, Shota arrives at the same beach as the creature. Asa and Kasuga finally get up in the air and do a fly by, but the creature damages their plane, causing them to lose altitude. Will Asa be able to regain control?
