Lou

Lou is a living doll of the Shadow Mansion's Children's Wing, renowned for her strikingly refined appearance. Extraordinarily quiet by nature and nearly devoid of personal will, she defines her entire existence through the flawless execution of her master Louise's commands—earning her the reputation as the most exemplary doll the mansion has ever seen. Though she initially presents herself as an emotionless instrument, her journey alongside Emilico and others gradually reveals a remarkable perceptiveness that aids her companions, while quiet bonds of friendship begin to blossom beyond the boundaries of mere servitude.
