Louis Arneb

Louis Arneb is a former Sin Archbishop of the Witch Cult, representing the satiation aspect of Gluttony. First introduced in Arc 5, she later served as one of the main antagonists of Arc 6, alongside her brothers, Lye and Roy. She later becomes a supporting character in Arc 7. After a chance encounter with Natsuki Subaru, she learned of Return By Death, ate his memories, and possessed him using a copy of herself in order to gain his authorities. However, Subaru ultimately managed to defeat her and left her for dead during the events of Arc 6, though she is later revealed to have survived at the cost of amnesia herself; bearing a completely new personality. She was transported along with Rem and Subaru to Vollachia at the end of Arc 6. Currently, Louis is accompanying Subaru, Vincent Abellux, Medium O'Connell, Al, and Taritta to the Demon City of Chaosflame, in order to try and prevent 7th ranking Divine General Yoruna Mishigure from joining their enemy's camp and act against Vincent. In contrast to her brothers, Louis has large blue eyes, light skin, and extremely long blonde hair that can cover the floor like a golden sea. However, as is the case with Lye and Roy, she has fang-shaped teeth which help her smile look to be one more reminiscent of a menacing smirk. She is physically in her mid-teens, although her exact age is unknown. During Arc 7, her hair is tied back in a ponytail after Subaru is reunited with her and Rem. Louis's debut featured her in her brother Lye's black cloak that was tied just below her neck with uneven tears along the lower portion. However, in Arc 6, she presents herself in an elegant white dress close to looking transparent. It comes with a jabot that has two small red lines along the leftmost side. This look is maintained after she leaves the Corridor of Memories. As Louis's physical self had been trapped within the Corridor of Memories until Arc 6's climax, she occasionally possessed the bodies of her brothers in order to experience the outside world. Subaru describes her as a girl that'd look good with a smile, yet he describes her "smile" as a smirk, and gave off the feeling that she made light on the lives of many people. She is also described to be evil intent in the shape of a child. Louis doesn't care much about what she eats, putting more emphasis on who she wants to eat, befitting of her role as Satiation. Also, the three speak in a collective manner using us and we instead of first or third person. Being the youngest sibling, Louis initially​ gave off the impression of being respectful and loving towards her brothers, but later reveals that she found them idiotic for blindly eating lives for her just because she was unable to exit the Corridor of Memories. Louis believed that life was unfair in a manner similar to that of a conveyor belt, without having the ability to choose the family, environment, and future to be born into. Because of these beliefs, Louis developed a goal of searching for, devouring, and becoming someone else all in the name of happiness, which would have allowed her to live with her head held high in a life she considers "ideal". In her desire to achieve a happy life for herself, Louis was very shrewd, claiming that Subaru helped Emilia, Beatrice, and Rem out of pity. She even claimed that he did it all for his own gratification as part of her plan to get him to reject the existence of ‘Natsuki Subaru’. After experiencing Return By Death, the Louis that had entered Subaru as a Witch Factor became traumatized and got into a fight with the Louis within the Corridor of Memories, who retained her original personality. The end result of this confrontation was that Louis lost her original mind, regressing into an infant-like state. After mysteriously materializing outside of the Corridor of Memories, Louis's mind deteriorated into an infantile state. She is currently incapable of speech and complex thinking, instead displaying a mind driven by instinct similar to an animal's. Interestingly, she seems to have an amicable inclination towards Subaru in this state, despite his previous actions against her. She would even go as far as to affectionately lick his face and protect him when others threatened his life, as was the case when she tackled Rem when the demon girl tried to strangle him. Even after Subaru treats her badly, Louis continues to act friendly towards him.
