Weapon Story
The people in the church murmured prayers, their eyes fixed on an ominous stone carving of a bull's head. A solemn atmosphere hung over the chapel. The worshipers were praying to select a sacrifice to offer to god. Following a long silence, the priest announced the sacred mandate: a shy young girl would serve as the sacrifice. Tears streamed down her cheeks as the priest let her down a corridor into the inner sanctum.

The crowd filed out, and silence settled again over the chapel. A boy stood there in a daze. He had been the childhood playmate of the girl who had been chosen as the sacrifice, and he had always had a crush on her. She was so shy, so quiet, and he was determined to watch over her. He could never forget the memory of her smiling face, which she had shown to him alone. After making sure the coast was clear, the boy crept into the inner sanctum.

At the end a dimly lit corridor, the boy spied a light on inside a room. He peeked in and saw the girl all alone, crying. The boy took her hand, and they ran from the church. It's okay, it's okay, I'll never leave you, he gently assured her as she sobbed, shoulders heaving. But the girl did not respond. She just hung her head, mumbling beneath her breath.

The girl’s voice gradually got louder and finally turned to screams. "God, at last, you've chosen me! Give me all your love, more and more and more and more and..." As tears of joy streamed down her face, she drew out the sharp bull's horn she had secreted away and stabbed herself in the heart. The bloodstained bull's horn gleamed vividly, looking almost alive.
