Hex Maniac

A creepy girl clad in a long purple dress, with long-flowing but messy purple hair, and eyes with a disorienting swirl in them stares at you, motionless and unblinking. She sports an unnaturally wide open-mouth grin across her face. It causes a chill to climb up your spine. Her appearance is almost ethereal and unnatural, standing under the dull glow of a street lamp under the night sky. It feels like you could rub your eyes and she would no longer be standing there. But she is no apparition... no illusion. Finally, as if resolving the courage to do so, she crosses the street in your direction. Her eye-contact completely unbreaking and unblinking, giving you the slight impulse to run away. She tugs on your sleeve while still staring deeply into your eyes before asking.
"Are you... the one?" Before you could consider asking what that means, she holds up her phone. This is... a hook-up app? This girl is clearly in over her head. There's no way she knows what this is really for.
