The wicked multi-billionaire, Shinatora, builds wretched, ugly buildings. The explosives genius calling himself Benten has targeted Shinatora`s empire and begins to destroy the monstrosities that are wiping out whole sections of downtown Tokyo. In cooperation with the local police force, the FBI has sent Lisa Hoshino, a bomb disposal expert, and her robot assistant, Dandy, on a lecture tour of Japan. Ryotsu is reluctantly paired with Lisa to protect the people of the Kameari district. Why does Benten only target Shinatora`s buildings? What is his next target? Another email warning arrives at the Katsushika Police Station. Benten`s next target is the newly built, gigantic amusement park, Shinatora World. Lisa and Ryotsu hurry to the scene. What they find is a huge Soviet-era rocket armed with a massive bomb powerful enough to obliterate the entire area of Katsushika. What can Ryotsu do?
