Rui Arneb

Louis Arneb (ルイ・アルネブ) is a Sin Archbishop of the Witch Cult, representing the satiation aspect of gluttony.

Appearance
Louis is a large and muscular man with long dark brown hair. According to Otto, Louis has an evil glimmer in his eyes similar to Ley, but "on a different level".

Personality
Unbefitting his stern look, Louis speaks like a woman. He refers to Ley and Roy by their names, hinting that the three of them are siblings. Unlike Ley and Roy, Louis doesn't care much about what he eats, putting more emphasis on who he eats with. Also, the three speak in a collective manner using us and we instead of first or third person.

Abilities
Authority of Gluttony (暴食の権能 Bōshoku no Ken'nō): Louis is able to use the Authority of Gluttony.
 * Gluttony (暴食 Bōshoku)
 * Louis can eat the name and memories of his opponent. Those that have had their names eaten have their existences erased from the world, destroying any human relationships along with preventing the use of magic and negating any contracts with Spirits. Those that have their memories eaten become amnesic and any characteristics they may have had are reset, effectively making them into a different person. Those that have both their name and memories eaten simply become a shell, and although they live, they no longer eat, excrete waste, or age, putting them in suspended animation. Things such as experience, talent, and the likes and dislikes of human relationships serve as food for Louis. However, if Louis eats a fake name, he becomes plagued with severe nausea. Louis can use the memories of people to use their abilities or learn about their or others' fighting styles and past.
 * Eclipse (蝕)
 * Eclipse is considered to be the trump card of gluttony and is also implied to have two types; solar eclipse and lunar eclipse.
