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.

Asa reluctantly agrees to accompany Yone to an audition at an entertainment agency. However, before they can leave, Mr. Jissoji shows up with news--the mysterious creature has been spotted! With Kasuga nowhere to be found, Asa prepares to take flight to identify the creature. But before she can, Nakaido runs in claiming to have found its weakness, earning himself a seat in Asa's plane as they take to the skies.
