Before her induction into Rhodes Island, she was a college student with two specialties: advanced medical Arts and intervention counseling. Skilled in both medical and combat Arts, she currently works in Rhodes Island's triage section while receiving treatment for her mid-stage Oripathy.

She is on friendly terms with [[Perfumer (Arknights)|]] who regularly assists with her rehabilitation.

Her motif is based on cats. Her callsign is the alter ego that manifests within her, caused by Oripathy. Because of it, she insists to be called by her real name instead.

Her [[voice actor]] is [[Takahashi Rie]].
