Childe Tartaglia is one of the eleven Forerunners, the ruling upper class of Fatuya, which you can't tell from his youthful appearance. He is a wolf in sheep's clothing. Behind his relaxed and friendly exterior lies a deadly swordsman. He is both the youngest and most dangerous of the Forerunners of Fatuah. However, Childe is at odds with the rest of the organisation. Being a consummate warrior, he does not agree to its deceitful and treacherous ways of operating.
