Xiao has a reserved and callous demeanor, which can make him appear intimidating to others. This is partly due to his reservations about the violent deeds he has performed and the loss of his allies over the years. However, deep down, Xiao is a gentle soul who is curious about humanity, but he is hesitant to show that side of himself due to his past experiences and karmic debt. He is highly loyal to Morax and carries out his duty of protecting Liyue with great dedication.
