Louie Barton suddenly transmigrates into a private hospital anomaly instance and activates the Anomaly Kin-Binder System: the S-rank head nurse is declared his aunt, and the instance UI sets 'Escape the hospital' as the main quest and 'Collect patients' fees' as a side quest. He finds two adults and a child; other survivors resent the kid, calling him a burden, while a Nightwatch member insists on protecting the child. Tension rises as arguments break out and anomalies multiply. A trapped voice gasps, "I... can't breathe," leaving the group's escape in immediate jeopardy.
