Despite holding one of the most senior positions in the Fatui as one of the Eleven Harbingers, Childe very much looks like the young adult that he still is. He is a wolf in sheep's clothing, however, for under the cheerful and confident appearance lies a deadly swordsman. He is the youngest among the Harbingers, but one of the most dangerous among their number. That said, Childe doesn't seem to fit in well with the others. As a fighter first and foremost, he is quite at odds with this company.
