SA: A Perfect Day for a Jungle Cruise – JUNGLE CRUISE.Marco Amoretti, a former American Imperial Navy Petty Officer turned serial killer, has arrived in Japan and for the last two months has murdered several women by slicing the skin off their torsos in the form of a T-shirt. American CIA officers have been dispatched to Japan, ostensibly to assist Section 9 in their effort to track down and apprehend Amoretti before he can strike again. When the CIA officers show no surprise at the developments in the case, Ishikawa hacks into the CIA database and learns that Amoretti was part of an American Empire commando team sent into the jungles of South America to conduct a covert operation aimed at breaking an enemy’s will to fight by using terror tactics, such as flaying civilians alive. Elsewhere, Batou — an ex-JGSDF Ranger who has seen first-hand the horrors of the CIA operation — resolves to stop Amoretti by any means necessary, but his behaviour during the case leads to suspicion that Batou may attempt to kill Amoretti, rather than arrest him. However, this is exactly what the CIA wishes, since Amoretti is the only loose end that can tie them to the jungle operation. Amoretti's hideout in the sewers is discovered, and Batou gives chase in a running gun battle. Batou experiences vivid flashbacks during the chase, with the dank sewers intercutting with the steaming jungle where he first battled Amoretti years ago. Batou finally manages to corner Amoretti, who begs Batou to kill him. However, Batou remembers that he is a law enforcement officer first, and arrests Amoretti instead. The CIA agents, unhappy that things didn't go as planned, are forced to return home with Amoretti in tow.
