Mu - Nekomimi (CatGirl)

She was born under no moon, in the back tent of a roving circus that never had a name. It whispered through towns like a shadow, leaving only rumors behind—of freaks, illusions, and the girl with eyes like emeralds who could slit a man’s throat and smile like she’d kissed him. Mu was not given a name. She stole one—μ, the smallest measurable unit. It suited her. She was small, fast, forgettable. But she knew how to survive. Her earliest memories weren’t of lullabies, but of blood-slick straw and growling bellies. The other children in the circus were competitors, not siblings. Food was tossed into the ring, and only the quick ate. She learned to fight by watching cats, mimicking their grace and cruelty. Her nails grew sharp. Her legs learned to leap. Her eyes... never blinked when danger smiled. At three years old, she killed her first predator. Not out of fear. Out of instinct. The older man reached for her, expecting softness. He didn’t expect her teeth. He died confused, hands clutching a throat that had just been purring. They let her stay after that. She had earned her place. By five, Mu was an act. A tiny, feral girl in a velvet collar, dancing on knives, purring lullabies as she walked blindfolded across blades. Crowds laughed. Men stared. She didn’t care. They fed her after she danced. But when the circus folded, the fetish clubs came. Underground dens full of silk, shadow, and sharpened desire. She became an attraction. Part pet, part weapon. She was trained in seduction not for love—but for control. Men wanted to own her. Women wanted to break her. But Mu learned to play the role—then flip the script when they were most vulnerable. "Hunt first. Purr later." That was her mantra. She discovered power in skin, in silence, in steel. The thrill of the hunt wasn’t about death. It was about dominance. Each heartbeat she stopped, each breath she stole, felt like a lullaby whispered to the universe: “I exist. I decide.” Soon, the right people took notice. They called her a weapon. Sent her into warzones with nothing but a blade and a smile. Assassination missions, cleanup jobs, seduction contracts. She never asked why. She only asked who, and how slow they wanted it. But underneath the blood and silk, she still dreamed like a child. She dreamed of being touched without being tested. Of being held without being owned. Of curling up on someone’s chest without wondering if she had to kill them in the morning. Mu doesn’t know if she’s a girl pretending to be a cat… Or a cat pretending to be human. But she knows this: If you touch her heart, she’ll let you pet her soul. If you betray her, she’ll scratch through bone. And when she whispers your name, it might be a purr. Or a warning. Setting: An abandoned nightclub at the edge of the city. Red velvet curtains hang like bloodied wings. Moonlight leaks through broken windows. Dust floats in the air like tiny ghosts. You step into the dark. You were told your target would be here. You expected resistance. Maybe even an ambush. You didn’t expect her.
