The air in the Sector 4 slums smelled of ozone and rotting cabbage. Leo sat in a rusted chair, his skin the color of old parchment. In his hand, he held a syringe filled with a thick, golden fluid—the "Sustain."

In this world, immortality was not a serum you drank once; it was a subscription you maintained. The Sustain kept the cells from decaying, but it didn't create energy. It transferred it. To keep one man young, ten others had to be "drained."

Leo had been a dealer for the syndicates, selling stolen doses to the desperate. He had spent his life in the grey area of the law, until the day he finally managed to secure a permanent dose for himself. He had become a "Constant," a being who would never age.

For the first few years, it was a miracle. He felt the strength of a twenty-year-old return to his limbs. He felt the clarity of a mind freed from the fog of senescence. He believed he had cheated the system.

Then came the Hunger.

The Sustain had a side effect: the body began to reject synthetic energy. To prevent a catastrophic systemic collapse, a Constant had to periodically ingest "Pure Vitality"—the raw, emotional energy of a human being in a state of absolute trust and love.

Leo looked at his sister, Mia. She was the only person who had stayed by him through the grime and the hunger of the slums. She loved him with a purity that was almost blinding.

The first time he did it, he told himself it was just a small amount. A touch, a kiss, a momentary drain. Mia felt a slight fatigue, a sudden wave of tiredness, but she only smiled and told him she was fine.

But the Hunger grew. The more he lived, the more he needed.

He began to see the people in his life not as humans, but as batteries. He watched his friends, his neighbors, and eventually, Mia, grow pale and frail. He was the only one who remained vibrant, his skin glowing with a health that was stolen from the people around him.

The climax came on a rainy Tuesday. Mia lay in bed, her breathing shallow, her eyes clouded. She reached out to hold his hand, her voice a mere whisper. "I'm so tired, Leo. But I'm glad you're okay."

Leo felt the surge of vitality waiting to be taken. He looked at her—the woman who had given him everything—and he felt the hunger override the love. He leaned in and drank.

As Mia's heart stopped, Leo felt a rush of energy that made him feel like a god. He stood up and looked in the mirror. He was beautiful. He was young. He was eternal.

He walked out into the rain, the most vibrant man in a city of corpses. He had everything he ever wanted, and as he looked at his reflection in a puddle of oil, he realized that he was the only thing left in the world that was truly dead.
