Height 156cm (5'1") An amnesiac little girl who finds herself in a mysterious building. Being very calm and collected, she's often described as being extraordinarily dull but painfully honest, with some even remarking that she resembles a porcelain doll due to her difficulty in visibly expressing emotions and always having a strange, blank stare regardless of her mood. She's fixated on the idea of God, often overthinking her relation and worth to him, as well as projecting his will onto various events in her life, even desiring punishment and death once she labels herself a sinner.

Spoiler

She exhibits a strange obsession with desiring "ideal" things, often stitching them together in order to make them "hers" and panicking if they don't meet her criteria, regardless of whether they are objects, people, or dead animals.

Spoiler

Ultimately revealed to be the master of floor B1, which is modeled after her family home, although filled with absurd traps. A number of items have been added to it by Danny, such as toys and fake flowers.

Spoiler

Her obsession with sewing things together stems from an unspecified mental health issue affecting her ability to feel empathy. Following an incident in which she stitched together a dead puppy's corpse, her parents' arguments escalated, with each of them blaming the other for Ray becoming the way she is.
