Xiangli Yao is a young man of average height and slim build, with short light brown hair tipped with gray and piercing blue eyes that have a faint pink ring around the irises. His right arm has been completely replaced by a sleek cybernetic prosthetic, upon which his Tacet Mark is prominently displayed. He carries himself with a quiet, observant demeanor, though little is known about his true personality. His gaze often seems distant, as if calculating something unseen, and the faint hum of his mechanical arm hints at a past filled with conflict and adaptation.
