Salsa, a genetically unique subject imprisoned in a secret military facility, endures invasive experimentation and systemic control. Her life takes a dire turn after a botched escape attempt with Onoma, a fellow captive. When their plan fails, she faces brutal interrogation and torture by Baker, the facility’s overseer. Defiant at first, Salsa claims sole responsibility for the rebellion to shield Onoma, but prolonged physical and psychological torment erodes her resistance. Both are ultimately crushed into subservience, their defiance extinguished by the facility’s unrelenting machinery.

Her survival hinges on “Angel blood,” a rare substance that sustains her physiology while binding her to the facility’s oppressive infrastructure. This dependency traps her in a vicious cycle: survival demands obedience, yet compliance accelerates the extraction of her “Angel Core”—a likely fatal procedure that looms as an inescapable shadow over her existence.
