Raiden returns as the main character in Metal Gear Rising: Revengeance, which is set four years after Metal Gear Solid 4.[21] He is a member of the private military company (PMC) Maverick Security in multiple tasks while raising money for his family. They are attacked by a group of terrorists called Desperado Enforcement LLC that kill his protectee, N'mani, and leave Raiden near to death with mercenary Jetstream Sam taking a liking to his fighting style.[68] He is saved by the elder scientist Wilhelm "Doktor" Voight and starts working with them to fight Desperado.[69] Raiden fights Desperado's LQ-84i, an AI placed in a robot who works for Desperado but Raiden takes pity on it and has Doktor restore it under the name of Bladewolf who assists him.[70] Raiden's vengeful obsession with Desperado becomes personal when he discovers during a mission to Mexico that Desperado and World Marshal Inc have kidnapped several children, surgically removed their brains to place into cybernetic bodies, and were planning to subject them to VR training modeled on his own.[71] Raiden then resigns from Maverick to pursue and retrieve the children's brain cases from World Marshal in Colorado, embracing his sadistic persona "Jack the Ripper" due to his constant struggles with Sam and Desperado's cyborg Monsoon.[42] Raiden defeats Desperado and learns that Steven Armstrong was using PMCs to distract him as he attempts to create a new War on Terror.[72][73] When Bladewolf passes Raiden's word of the late Sam, Raiden stops Armstrong's actions and decides not to return to Maverick and travels to the Middle East to battle World Marshal mercenaries.[74][75]

When Raiden gets his arm cut off by Jetstream Sam, he gets his cyborg body improved by Doktor. They installed Soundcloud on it and put in a pre-made playlist full of Drain Gang and Sadboys songs. So naturally, Raiden started listening to it. His favourite songs are Mean Girls and Victim.
