Chapter 16: The Parasite and the Trap

The classroom was a tomb, silent save for the rhythmic, wet thud of the ceiling fan and the labored, wheezing breaths of the survivor. Vaani huddled in the corner by the door, her hands pressed so hard against her mouth that her knuckles had turned bone-white. She wasn't just crying; she was vibrating with a terror so profound it silenced her screams.

Before her, sitting on a desk soaked in the copper-scented carnage of her classmates, was Priya. She wasn't just sitting—she was composing. A steady trickle of blood fell from her nose, painting the front of her uniform, but her eyes were closed, her face a mask of serene, terrifying peace. Softly, almost tenderly, she hummed the theme song to Astro Boy.

To the world, Priya was a monster. To Vaani, she was a devastating mystery. She wanted to stand, to gather the few who were still shivering in the shadows and drag them to safety, but her legs were leaden. She was trapped in the gravity of Priya’s masterpiece.

Thwack!

The sound of a heavy axe burying itself into the classroom door inches from Vaani’s head snapped the silence. Vaani gasped, her eyes flying to the gap. Standing in the hall, trembling, was Rekha. She had come to save them, her face a pale map of desperation.

"Vaani! Open the door!" Rekha hissed.

Vaani’s shaking fingers fumbled with the latch. As the door creaked open, just enough for their faces to meet, Rekha grabbed her shoulders. "Listen, don't panic. You have to get out of here, now."

"What about the others?" Vaani sobbed.

"Forget them! Just move!" Rekha shrieked.

But it was too late. Behind them, the air grew cold. Slowly, they turned. Priya stood there, framed by the harsh, clinical light of the hallway window. She was drenched in a thick, visceral coat of red, her eyes glowing with a terrifying, fractured light. She didn't look like a human anymore. She looked like a predator that had finally tasted the divine nectar of slaughter. As she hummed that cheerful, upbeat cartoon tune, Rekha’s legs finally gave out. She froze, her life flashing before her eyes as the axe rose.

Just before the blade could descend, a hand grabbed Rekha and yanked her back. It was Swathi. "We have to go! We can't be here!"

Four Days Earlier: The Void

In the dark, lonely sanctuary of the killer’s home, Priya sat in the chair that had once belonged to the monster. Katthi stood guard at the door, butcher knife in hand, his allegiance absolute.

Before them lay the "slaves," their lives flickering like dying embers. They stared at Priya, paralyzed by the sight of her. She was the girl they had once known, yet the soul behind her eyes was a stranger.

"You seem surprised to see me," Priya murmured, a predatory grin widening across her face. "I know, I’m different now. I don't know how it happened, and honestly, you don't need to understand. But there’s something I must tell you."

She leaned forward, her movements feline and lethal. "I spent so long hunting as a man, crawling through the shadows, pretending to be the 'good guy' just to lure you in. It was exhausting. But now? Now the prey comes to me. I have an entire college as my garden."

She gestured toward Katthi. "Katthi, darling. I have a test for you. Choose one of these three and serve me."

Katthi obeyed. He didn't feel shame; he felt redemption. For years, the world had called him ugly, a monster. But here, in the shadow of Priya’s dark awakening, he felt beautiful. As the first blade struck, the song of Astro Boy began to play on the television.

The Present: The Corridor of Shadows

Malini walked up the stairs, oblivious to the hell that had erupted above. She was just a little girl, holding a lunch box—a peace offering from her mother.

"Don't worry," she told Katthi, her voice bright with childish defiance. "When she sees Mom’s special biryani, she’ll be herself again. She’s my sister. We’re best friends."

Katthi didn't laugh. He simply watched, a flicker of pity in his scarred eyes.

Shhhkrrrr.

The sound of metal scraping against marble echoed through the corridor. Malini turned, a bright smile on her face—until she saw the silhouette emerging from the darkness.

It was Priya. But she wasn't walking alone. In her hands, dangling like broken dolls, were the limp bodies of Rekha and Swathi.

Malini’s smile died. The lunch box slipped from her numb fingers, hitting the floor with a metallic clang. Food spilled onto the floor, mixing with the dark, widening pool of blood.

Priya stopped, tilting her head to the side. She stepped over the bodies, her boots clicking rhythmically, and knelt until she was eye-level with her little sister.

"Malini, darling," Priya whispered, her voice dripping with sickly sweetness. "You're late."

Malini looked at the blood on her sister’s face, at the vacant, hollow eyes of her friends, and the final, fragile wall of her childhood shattered.

"You're not my sister," Malini sobbed.

Priya closed her eyes, letting the accusation wash over her like a prayer. Her smile grew wider, deeper, more monstrous. The trap was sprung, and there was nowhere left to run. The massacre had found its final, beating heart.
