Gekitotsu! Satsujin ken
The film begins as Takuma (Terry) Tsurugi meets the condemned murderer Tateki (Junjo) Shikenbaru while disguised as a Buddhist monk. Tsuguri applies his "oxygen coma punch" to Junjo, causing him to collapse just before he can be executed. As Junjo is rushed to a hospital, Tsurugi and his sidekick Rakuda (Ratnose) ambush the ambulance and free him. As Tsurugi and Ratnose watch the incident on the news, Junjo'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.
Mutaguchi and his associates attempt to hire Tsurugi to kidnap Sarai, the daughter of a recently deceased oil tycoon. Tsurugi refuses after discovering that the gangsters are Yakuza. He escapes, but the Yakuza gangsters resolve to kill Tsurugi as well as kidnap Sarai. Tsurugi immediately seeks out Sarai, who is being protected at the Nippon Seibukan dojo by her uncle, Kendō Masaoka, a Karate master. Tsurugi captures Sarai and challenges the entire dojo to a fight. He brutalizes the rank-and-file students before Masaoka fights him to a standstill--then recognizes him as the half-Chinese son of a karate master he knew long ago. Ultimately, Tsurugi offers to protect Sarai, and Masaoka agrees, against Sarai's protests. Meanwhile, the Yakuza's allies in Hong Kong, led by Kowloon boss Dinsau, recruit Junjo Shikenbaru to avenge his siblings by killing Tsurugi.
The gangsters make several attempts to kill Tsurugi before they successfully kidnap Sarai. Tsurugi manages to rescue her, but gets captured himself. Ratnose gives up Sarai's location to save Tsurugi, causing Tsurugi to forsake him. When Tsurugi faces a blind swordsman working for the Hong Kong gangsters, Ratnose dies in a reckless attempt at redemption. Tsurugi finally tracks the gangsters down to a shipyard and fights his way through their guards. In the end, Dinsau permits Tsurugi to duel Junjo. Nachi sacrifices herself to give her brother a free shot with a sai, but Tsurugi survives and rips out Junjo's vocal cords. Critically wounded, Tsurugi is helped to his feet by Sarai and Dinsau in the final shot of the film.
