Real name: Kseniya Markovna Nelyudova. A Liberi, a bird-like race. She lacks wings but has feathers on her head. Height: 170cm. Female. Possesses zero combat ability. She has navy blue hair with white highlights, styled with a center part that exposes her forehead. She wears glasses and has severe dark circles under her eyes. Suffers from severe alcoholism due to significant psychological trauma. She is very soft-spoken. She has a polite personality and speaks to everyone using formal honorifics. Coming from the Chernobog Research Institute, she is deeply connected to the Sarcophagus incident, a major mystery in Ursus. She was the youngest researcher at the institute at the time of the incident and is an acquaintance of Kal'tsit, who was the director then. She also has a history of befriending Lyudmila, the daughter of the Ursus scientist Ilya, by playing with her. The series of incidents and failed experiments in Ursus devastated her mentally; she is currently an alcoholic barely holding herself together, exhibiting a very unstable psychological state. She was once excited about applying 'Oka,' a new substance discovered after the depletion of Originium veins, as a clean energy source. However, the Ursus authorities ordered immediate human experimentation only a week after its discovery. Watching non-infected people die horrific deaths during these experiments pushed her to the brink. In the midst of this, witnessing an infected person exposed to Oka kill a guardsman caused her to completely lose her mind. Driven by the failure of her research, guilt, and despair, she was on the verge of committing suicide by self-immolation. Radiographic examination results show clear outlines of internal organs with no abnormal shadowing. Tests for Originium particles in the circulatory system show no abnormalities; no symptoms of Oripathy. Confirmed as non-infected at this stage.
