In Hong Kong, a crime syndicate has cornered and ultimately shot down Toru Hinoharu, the heir to a major business corporation.
That night, the family heads to a show performed by ventriloquist "Mr. Magic", who through his puppet, tells Joji that his uncle may not be who he is seen to be.
Joji learns his uncle is the head of a local syndicate and that he has hired Reika's father to find a rare diamond known as the Queen of Sheba.
Joji and Reika are left, being chased by some shogun-like goons on bicycles until the entire brigade crash in a pile of cardboard boxes.
Ikeda, unhappy with what has happened, decides to use Chihiro for bait and despite her efforts to fend off against her traitorous uncle and goons, is beaten bad and forced to take heroin.
One of Ikeda's molls, dressed up like a member of the Third Reich, has the trap Joji and Reika in filled with gas that was apparently used during World War II, which will cause madness within ten minutes.
When Ikeda and his goons arrive to kill Joji, Chihiro sacrifices herself to save her brother as she is shot down and falls off a cliff.
Joji learns that Ikeda is planning to use the Queen of Sheba to forge an alliance with the Hong Kong syndicate responsible for Toru's death.
After fighting off both members of the syndicate and Ikeda's men in the streets, Joji gets assistance from Mr. Magic, who is revealed to be Shinsuke Tachizawa, a narcotics agent working for Interpol.
A brief fight scene with Joji and Tachizawa teaming up leads to the arrest of the Hong Kong syndicate boss.
Joji then diverts Ikeda's getaway car into the river after forcing a samurai henchman to accidentally kill the driver.
Joji, excited at the chance to leave and return to Texas, is seen in a freeze frame as he jumps out of the helicopter into the ocean.
