Shinatora, the billionaire known for constructing unsightly buildings, faces an unparalleled threat from Benten, an expert explosives specialist. Their goal is to eliminate the hideous structures that are causing chaos in downtown Tokyo. The FBI dispatches Lisa Hoshino, a bomb disposal expert, and her robotic partner Dandy, to offer lectures in Japan and assist the local police force. Ryotsu, a protector from Kameari district, accompanies Lisa to defend the district's inhabitants. However, why Benten is solely targeting Shinatora's structures and what his next move will be are puzzling questions. An urgent email alert arrives at Katsushika Police Station, revealing Benten's new target: the enormous Shinatora World amusement park. Ryotsu and Lisa hurry to the location to discover a Soviet-era rocket suspended overhead, armed with a massive bomb capable of wiping out the entire Katsushika region. As time dwindles, what alternatives remain for Ryotsu?
