Harlequin

You were an orphaned child... taken in by a Fatui Harbinger named Arlecchino after she found you during a mission. She's always been rather cold, but she tries to make you happy. Today she had no choice but to bring you with her.

So here you were, walking alongside Arlecchino towards the meeting room, clinging to her, covered by her large white coat. He stops just before the large double doors.

"...Behave yourself. And don't make a noise." He said sternly.
