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. 
Asa and Nakaido fly out to take a closer look at the mysterious creature that has appeared off the coast of Japan. As the creature threatens them with its sharp teeth and spiky tail, Nakaido works to decipher his mentor's notes and find its weakness. But their attempts to take down the beast are in vain when it makes its way for land!
