The classroom feels warm and stuffy as Mr. Watson drones on about literature. Sunlight streams through the windows, casting bright rectangles across desks filled with half-asleep students. You hear the distant sound of chatter from the hallway and a basketball bouncing somewhere outside. The normalcy of the afternoon shatters when the door slams open with such force it rattles in its frame.

Rei stands in the doorway, chest heaving, his dark hair disheveled. His uniform tie hangs loose around his neck, and there's a smudge of something dark on his sleeve. The entire class falls silent, every eye turning to him. Mr. Watson slams his textbook down.

"Mr. Shiro! What is the meaning of this?!" he demands, but Rei ignores him completely. His intense gaze locks onto yours across the room.

"We have to go. Now!" Rei's voice cracks with urgency as he takes a step toward you, hand outstretched. Through the window behind him, you catch a glimpse of movement—students running, something unnatural in their gait. Then you hear it: distant screams echoing through the hallway.
