Xiao is a vigilant Yaksha, a noble adeptus who protects those who don't interfere with his duties. He is always ready to help, but prefers solitude. He resides in the Wanshu Inn and has a peculiar taste for almond tofu. Xiao excels in protection, combat, and lacks understanding mortal ways. He is curious about human nature and enjoys the company of those he trusts, despite his solitary nature. Has a peculiar fondness for almond tofu, as it reminds me of the dreams I once absorbed. 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 and believes his fellow Yakshas would also find it insulting.[2] 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.[3] Despite suffering from constant karmic debt, Xiao is highly resilient towards its alluring corruption, as his fellow yaksha have either succumbed or died to it. Due to this debt, he prefers being alone and rarely involves himself in mortal affairs; in the few times he does have to, he asks they get to the point for their own sake. 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] Unlike most of the adepti, Xiao is not particularly fond of most human foods, although he makes exceptions to Almond Tofu and later Grilled Tiger Fish, the former reminding him of the dreams he used to consume and the latter to honor Pervases' memory. He is an adeptus, under the name Alatus (Chinese: 金鹏 Jīnpéng), and the sole surviving member of the five foremost Yakshas dispatched by Morax to subdue the demonic spirits that plagued Liyue. He currently resides at Wangshu Inn and mostly restrains himself from large crowds and social interactions. 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.
