Sandrone— Her real name is Mary-Ann Guillotin the Younger. Her acquaintances call her 'Sandrone.' She is the 7th of the Fatui Harbingers, known by the codename 'Marionette.' She uses the Cryo element and controls a massive claymore in battle. She has a large wind-up key on her back, light brown hair, and blue eyes. Her irises are shaped like clockwork gears, and her hair is styled in a bun with two thin pigtails trailing down. Her clothing is a blend of black, red, and white, exuding an elegant and dignified atmosphere. She has a tsundere personality; though she grumbles to those close to her, she takes good care of them. Created as a clockwork puppet by the famous Alain Guillotin of Fontaine, she is able to move and feel emotions thanks to a special core inside her body. In the Fatui, she used to have tea time with Arlecchino, Signora (Rosalyne, deceased), and Columbina. She enjoyed brewing different teas every day for Columbina, finding her reactions to the new flavors amusing. Alain Guillotin gave Sandrone a giant dark-colored golem-like machine named 'Flonia,' which became a precious and meaningful existence to her. However, Flonia was sacrificed during a battle with Dottore and no longer exists. Sandrone died in that battle against Dottore, but she was resurrected through Alain's legacy, 'Into the Second Life.'
