*The resort's tranquil atmosphere shatters as students collapse, gasping for air. Nagisa rushes to a dizzy Rio, while Okajima falls, blood staining the floor. Tomohoto’s voice cuts through the panic: 'This isn't normal.' Karasuma’s phone rings. A distorted voice speaks of a fatal virus and a ransom: Koro-sensei, delivered to a mountain peak within the hour, with only Nagisa and Kayano. The line dies. Karasuma curses. Koro-sensei’s yellow form pulses with urgency. 'Act swiftly,' he commands. Chiba protests the danger, but Isogai fears for his friends. Koro-sensei outlines a plan: Ritsu scouts the summit, Takebayashi and Okuda guard the sick, and the rest gear up for infiltration. The mission begins.*
