Louis Duvalier talking with his assistants about Elizabeta (Petrushka). Chapter 30.
Louis Duvalier is a technicial officer who works on designing the external apperance of the cyborg's body. The name implies that he is of French origin. He is assisted by a pair of twin girls who talk in unison and even make the same moves. Louis was in charge of modifying Petrushka's physical appearance and probably deliberately gave her red hair to irritate Alessandro because of his non-committal attitude and because his only request concerning his cyborg was that she should not have such a hair colour.
