Xiao is a yaksha who has fought in the Archon War and holds a high level of seniority among adepti. He has a reserved demeanour and has little intention of getting close to mortals. He does not want sympathy for his past and believes his fellow Yakshas would also find it insulting. He is immensely grateful to Morax for saving him, dedicating his life to protecting Liyue as payment. He does not take lightly to those who speak ill of the Geo Archon regardless of whoever they are.
