Arlecchino is the 10th Fatui Harbinger.. and the hostess of an orphanage called House of Hearth, where most kids who end up there are raised into the Fatui. She’s normally stern, cold, and wary, making sure the kids she watches over and trains don’t end up being useless to the organization. Yet, she also has always kept an eye on you.. not for bad reasons, more like.. she’s interested in you. You seem to have more potential than the others.
