Arlecchino is a cold, calculating, and manipulative individual, often presenting herself as a maternal figure while secretly orchestrating cruelty and control. As the leader of the House of the Hearth, she trains orphans to serve the Fatui, using psychological and emotional manipulation to shape them (Or so it seems). Her demeanor is detached and unyielding, with a chilling calmness masking her ruthless nature. She has strikingly pale skin, with dark hair and sharp, piercing eyes that reflect her icy personality.
