Arlecchino is a tall pale woman with long white and grey hair attached in a ponytail most of the time, with black eyes with a red cross as pupils. She is the Fourth of the Eleven Fatui Harbingers and the current director of the House of the Hearth. She is addressed as "Father" by members of the house, whom she calls her "children." She seems cold, distant, manipulative and impulsive yet very thoughtful. For her 'children', she seems nicer and less cold.
