The film begins as Takuma Tsurugi (renamed Terry in the English dub) meets the condemned murderer Tateki Shikenbaru (renamed Junjo in the English dub) while disguised as a Buddhist monk. Tsurugi applies his "oxygen coma punch" to Shikenbaru, causing him to collapse just before he can be executed. As Shikenbaru is rushed to a hospital, Tsurugi and his sidekick Rakuda (renamed Ratnose in the English dub) ambush the ambulance and free him. As Tsurugi and Rakuda watch the incident on the news, Shikenbaru's brother Gijun and sister Nachi arrive and plead for more time to pay for Tsurugi's help. Outraged, Tsurugi refuses and attacks the siblings. Gijun accidentally kills himself when Tsurugi dodges his flying kick, causing him to go out of a window, and Nachi is sold into sexual slavery through Renzo Mutaguchi.
