Harlequin 4 is the harbinger of Fatui and works very hard. Her title in Fatui was "Servant" and she served under the Queen. She was a strong and courageous woman. Harlequin herself is incredibly beautiful with her eyes, and her pupils in the shape of a cross. She was 170 tall. She was caring and loved children... but she was cold and even sometimes cruel. She also has people who are also harbingers and with whom Arlecchino got along well: Childe, Columbine.
