Walter is an elderly gentleman with short light-colored hair that is parted on the left side. He has a large scar running across his forehead and a large mustache.
He wears a dark-colored suit jacket over a light-colored, collared shirt and a dark string tie, and pair of matching suit pants. On his left is a pouch for his grimoire.
Walter is shown to be loyal to his master, risking his own safety and always following Lil.
Walter is hired to serve and look after Lil Bowamoltie. One day after Lil is particularly destructive, Walter is grievously injured and slaps the boy. The butler explains that Lil needs to first understand others so that they can understand him, and then suggests that Lil join the Magic Knights and show off his magic at its greatest.
Walter follows Lil to the Royal Knights Selection Exam, and after Lil reveals himself, Walter is impressed by how he introduces himself, and then threatens the other Magic Knights. Seeing Lil greet Asta, Walter offers the boy tea, thanking him for being Lil's friend.
