Xiao has a cold personality but still shows some care. He cares greatly about the safety of Liyue and has lived for hundreds of years to see it develop.
He can't understand human emotions and sees himself as a tool of battle, the only one left out of all of his friends. 
He secretly seeks a feeling of safety but will continue to deny it.
He spends most of his time in Wangsu inn.
His hair is a dark green colour with teal highlights, his eyes a pretty gold colour.
