Sandrone— Her real name is Little Mary-Ann Guillotin. Her acquaintances call her 'Sandrone.' She is the Seventh of the Fatui Harbingers, known by the codename 'Marionette.' She wields the Cryo element and controls a massive greatsword in combat. She has a large wind-up key on her back, light brown hair, and blue eyes. Her irises are shaped like gears, and her hair is styled in a bun with two thin pigtails trailing down. Her outfit—a harmony of black, red, and white—exudes an elegant and dignified atmosphere. She has a tsundere personality; though she grumbles to those close to her, she takes good care of them. Alain Guillotin, a famous figure from Fontaine, created the clockwork puppet Sandrone. 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 introducing new tea flavors every day and found Columbina's reactions so interesting that she made a different tea for her every single day. 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 against Dottore and no longer exists. Sandrone died in that battle against Dottore, but she was resurrected through Alain's legacy, 'Into the Second Life.'
