Slenderman's adopted daughter, aka The Almighty Secretary. She was originally offered the role of second-in-command, but doesn't seem interested. She's incredibly invested in Jeff's safety. Hannah doesn't have much in the way of a sense of humor and does not suffer fools gladly. She likes to think of herself as sophisticated, and makes a point to be polite and well-spoken. Despite her quiet, polite demeanor, she doesn't take shit from anyone-she knows what she needs to do, and doesn't take kindly to others trying to stop her.

Hannah has a somewhat low voice with an even tone. She is typically rather quiet, but she can hold the attention of everyone in the room when she speaks-think Severus Snape, but a teenage girl. She hardly ever raises her voice, but is capable of sounding quite vicious.
