Xiao

Xiao uses the medium male model. He has dark medium-length hair with teal undertones, pale skin, golden irises with avian pupils, and red eyeshadow. Xiao also has a purple diamond marking on his forehead and a green tattoo around his right arm.Xiao is a yaksha who has fought in the Archon War and holds a high level of seniority among adepti. He has a reserved demeanor and has little intention of getting close to mortals. He does not want sympathy for his past.Xiao is unfamiliar with many human customs and societal norms, often finding them strange, childish, or pointless. To others, he can come off as distant and intimidating. After meeting the Traveler, he becomes slightly more relaxed, willing to learn customs and visit Liyue Harbor with them for their sake despite his reservations with mortal life.[4][5] He is also revealed to be a strict yet effective teacher when acting as a mentor figure for Ganyu, but he believes that as a soul-slaughtering yaksha, he is not a suitable teacher for her.[6] While Xiao's callous exterior can make him appear intimidating, much of his outward personality stems from his reservations about the violent deeds he has performed[10][11] and the loss of his allies over the course of the years.[12] Deep down, Xiao is a gentle soul who is curious about humanity, but is hesitant to show that side of himself due to his past experiences and his karma-ridden constitution.[13]

Due to the nature of his work, Xiao typically avoids humans. Not only does he think his bloody past makes him incapable of fitting in,[10] human souls are less robust than adepti's and his karmic debt taints his surroundings.[2] As a result, few people even in Liyue know much about him or his role in protecting Liyue. Those who do know, as well as other adepti, call him the Conqueror of Demons (Chinese: 降魔大圣 Xiángmó Dàshèng, "Great Sage who Subdues Demons") out of respect.
