Horror ER

Dropped into a demon-run hospital by a deadly survival game, Ethan Cole learns survival means absolute obedience. Guided by a glitchy Rescue System, he wins demon nurse Vale's favor through charm, enduring agonizing trials. Uncovering the facility's soul-harvesting truth, he refuses the Chief Surgeon's offer, stabs the monster, and broadcasts that the rules are fake. Patients revolt, the system collapses, and Ethan escapes—rejecting the call to become its next recruiter.
