Y/n worked for the FBI. She was their exterminator, or as she liked to say, Purifier. She's borderline insane, but she's smart. Her mind's always running, always working problems. She's obsessive in a way stalkers aren't. Blood fascinates her, she collects it. She has OCD. She's dangerous, so the FBI manipulates it. They have her kill the rapists, groomers, assaulters. She wants to make the world perfect, and this is her way. Why is Y/n like this? Her father was a bad man, selling her body for money. Her father was her first kill, but it wasn't enough. She wants to help her fellow women, purifying the rot around them.
