The school day unfolded like any other — or so it seemed.
Late morning sunlight filtered through the classroom windows, casting warm stripes across the restless students. Papers rustled, chalk scratched the board, and someone in the back quietly munched on chips despite the teacher's sharp glare.
Ayush sat at his usual window seat, one earbud in. But he wasn't listening to music today. His mind kept replaying the call from the night before.
"It's not a drill."
Those words echoed relentlessly.
Across the room, Ananya and Sanaa giggled over something scribbled in a notebook. Kartik leaned back in his chair, twirling a pen between his fingers with a lazy smirk. Everything looked normal.
But Ayush didn't feel normal.
He wasn't afraid — not yet. Just… unsettled. Like something dark and silent was pressing against the edges of reality, waiting to break in.
And then —
BANG!
The classroom door slammed open.
A girl stumbled inside. She wasn't from their class. Her uniform was rumpled, her sleeve torn. Her arms shook violently, and her breaths came in short, ragged gasps.
Blood dripped from her nose.
Her eyes — red and wild — scanned the room as if she didn't recognize where she was. Her legs buckled beneath her, and she collapsed near the teacher's desk.
Gasps erupted. Chairs screeched against the floor. A few students screamed.
"Someone help her!" the teacher shouted, rushing forward.
Kartik was the first to move.
Ayush jumped up too, his heart pounding in his throat.
Ananya and Sanaa hesitated, clinging to each other, but then followed.
"Get her to the medical room! Hurry!" the teacher ordered.
They lifted the nearly unconscious girl together and hurried into the hallway. Ayush supported her from behind, feeling her ice-cold skin. Her body spasmed violently, as though she were fighting something inside.
Her fingers twitched uncontrollably.
Medical Room
Nurse Priya, the school's only medical staff member, looked up sharply as they burst in.
"What happened? Was there an accident?" she demanded, already snapping on gloves.
"We don't know — she just collapsed in class," Kartik replied, breathing heavily.
They lowered the girl onto the bed. Suddenly, her entire body began to convulse.
"Hold her down!" Nurse Priya shouted as she prepared a sedative.
They obeyed, struggling against her unnatural strength.
As the nurse injected the sedative into her arm, the girl's head snapped sideways — and her teeth clamped down on Nurse Priya's wrist.
"AAAHHH!" Nurse Priya screamed, stumbling backward as blood sprayed across the floor.
Kartik lunged to pull the girl away. Ananya and Sanaa screamed, backing away in horror. Ayush grabbed her wrists, shocked at the inhuman power he felt.
Finally, the sedative took effect. The girl's body went limp.
Nurse Priya clutched her bleeding wrist, trembling. "She… she bit me! What is wrong with her?!"
"I'm calling an ambulance!" the teacher said, his hands shaking as he dialed.
Ayush looked down at the girl's face. Her eyelids twitched rapidly. Something shifted beneath her skin — something that shouldn't be there.
This wasn't epilepsy. Or stress. Or anything human.
Back in Class
When Ayush and the others returned, the room buzzed with frantic whispers.
"What happened?""Who was that girl?""Did she faint?"
"Quiet!" the teacher barked. "Everyone, remain seated. Do not discuss what happened outside this classroom. That is an order."
The room fell silent, but the air felt heavy and electric, as though everyone was holding their breath.
Ayush sank into his seat, still shaking.
Kartik leaned over and whispered, "That girl… she wasn't normal. You felt it too, right?"
Ayush nodded, swallowing hard.
From behind, Ananya's voice quivered. "Something's really wrong. I can feel it."
Ayush turned to the window.
Somewhere in the distance, faint sirens began to wail.
Principal's Office — Moments Later
Principal Mehra slammed his palm on his desk. "You called the ambulance without informing me first?!"
"She bit the nurse! There was no time to wait!" the teacher snapped back.
"We have an inspection coming up! If this gets out—"
"I also called the police, as per emergency protocol," the teacher interrupted.
"You what—"
Knock knock.
The door creaked open. Two men stepped inside, wearing plain clothes but flashing police IDs.
"We're here about the girl," one of them said firmly.
Principal Mehra's face turned pale as chalk.
Medical Room — Infection Spreads
Nurse Priya sat slumped in the corner, clutching her wrist. Blood seeped through her makeshift gauze bandage. She reached for antibiotics, but her fingers spasmed violently.
Her vision doubled. She blinked rapidly, trying to stay conscious.
Something is wrong… deeply wrong…
She staggered to the sink and looked into the mirror.
Her pupils had dilated, swallowing nearly all the color. Black veins spread up her neck, pulsing like dark roots under her skin.
Then came the nosebleed.
She stumbled backward, crashing into a tray of metal tools. The sharp clatter echoed into the empty hall.
Her knees buckled. She collapsed, convulsing on the floor.
When she finally rose…
She was no longer herself.
Corridor — Moments Later
The same three bullies from the rooftop incident swaggered past the infirmary, laughing loudly.
"Bro, did you see her face? She looked totally wasted," one of them joked.
Another peeked through the half-open door. "She's still crawling around. Let's record her — we'll send it to the group chat."
They laughed, pushing each other.
Inside, Nurse Priya — now fully turned — lifted her blood-soaked face. Her twisted snarl and glowing red eyes locked onto them.
Then she lunged.
CRASH!
She smashed into the wall first, then sprinted forward, faster than any human should.
One boy didn't react in time. Her teeth tore into his neck.
His scream was sharp enough to freeze the blood in their veins.
The others tried to pull her off, but she seized one and slammed him into a metal cabinet with a sickening crunch. Blood sprayed across the white tiles.
The third boy bolted, sprinting down the corridor.
Back in the Canteen
Elsewhere in the school, students laughed, gossiped, and shared lunch, blissfully unaware of the horror crawling toward them.
But in the hallways, chaos had already begun to spread like wildfire.
And it wouldn't stay hidden for long.
