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.

After driving away "that thing" that appeared off the coast of Japan, Asa returns home to questions and speculation from her siblings and friends and a warning from Kinuyo--no more dangerous flying! Meanwhile, Jissoji goes to the hospital to visit the prime minister, who not only knows about Asa--he believes the fate of Japan rests on her shoulders! At the prime minster's insistence, Asa is told to be ready to spring into action at any time.
