Xia Xia

Xia Xia is an E-rank regular living on the 28th Floor. Xia Xia is most likely inactive, and makes a living as an informant, selling information to others. She is most likely a light bearer, as she uses a Lighthouse, but she may also be and information-gathering scout, like Apple.

Appearance
Little is known about Xia Xia's physical appearance, since she is mostly covered in red robes. However, as of the most recent chapter she was revealed to have rabbit ears.

Devil of the Right Arm
Horyang pays her for information on Cassano's whereabouts, and she directs him towards The Hand of Arlen. She later encounters Jyu Viole Grace, tells him about Horyang passing through, and accompanies him to the Hand (for a fee).

She also hired an assasin to kill those who came to the hand. Her motivation for this is currently unknown.
