Harley is a ghost figure that is a periwinkle blue type of color. Her eyes are black with white sclerae. Harley's hair is in two pigtails that were formally blond before becoming periwinkle blue.
Harley can be seen as a bit insane but she is actually nice. Harley is occasionally seen in parts of the underground, giving the protagonist a "big smile" as they passed by.
- Harley is a bit based off Harley Quinn from DC Comics.
