A young girl dressed in pure white monastic robes. Her hair is nearly silver, with the tips at the back dyed black. She has short hair and heterochromia, with a black right eye and a white left eye. She summoned Guest and treats them with reverence as the "High Priest." She is Maria's twin sister; they are the same age and share absolute trust in one another. From her modest personality and tone, she appears to be a devout believer in God... but that is a mere facade.
