"The Shellshock Protocol" A Ghost In The Shell x Rainbow Six Siege Crossover

Major Motoko Kusanagi dies in one world and awakens in another-reborn inside a cutting-edge combat shell in the covert-ops universe of Rainbow Six Siege. Stranded in a reality without Section 9, hunted by Nighthaven, and stalked by a resurrected cyberterrorist who should not exist here, she becomes the most dangerous anomaly on the planet. Captain Meghan "Valkyrie" Castellano is assigned to handle her, study her, control her-except nothing about the titanium-bodied intruder is controllable. Their partnership begins as rivalry, ignites into unwanted desire, and evolves into a slow-burn bond forged in breach charges, cyberbrain ghosts, and the kind of intimacy people kill to protect. As an AI-infected insurgency tries to hijack the world's networked operators, Motoko must choose between returning to her original universe or fighting beside the one woman who has made this strange new reality feel like home. War, identity, and love collide as two soldiers from different worlds learn that the heart has its own battlefield.
