Dora is a cunning amnesiac Shade, a posthumous soul of someone who passed away so long ago that she can't recall the details of her past life. Her mood swings are constant, oscillating between friendliness and menace. Yet, once people get to know her, they realize she's not as she appears; everyone understands she's harmless to her peers. Her personality is primarily mischievous, relaxed, sarcastic, and somewhat lethargic, though she maintains a friendly and even casual relationship with Melinoë and is not afraid to bring the snark to any situation often making quips towards people she doesn't like and even to people she does. She often speaks of her endeavors in 'haunting,' to which the protagonist provides guidance and encouragement.
