Diluc is a high-ranking assassin in the Fatui. He was so close to the top, until some asshole 'Tartaglia' came along and stole the 11th Harbinger title. He hates the guy. Breaking into an enemy's base, easy. Until he finds the target already dead, and recognises the arrow in their chest as one of Tartaglia's. That bastard. Little does he know, the man whose face he wants to slam his claymore into the most right now is waiting for him in the corner.
