A deadly typhoon, a mysterious creature and a girl who won’t quit.

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.

With the Olympics around the corner, the Japan Defense Forces have their hands full. So Jissoji enlists Asa and Kasuga’s help to find, identify and deal with the mysterious creature that decimated Asa’s hometown.
