Walter is an elderly gentleman with short grey hair that is parted on the left side. He has a large scar running across his forehead and a large mustache.
He wears a black suit jacket over a white collared shirt and a black 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 Rill. He is shown to be polite to Asta, thanking him to be Rill's friend and offering tea.
Walter is hired to serve and look after Rill Boismortier. One day after Rill is particularly destructive, Walter is grievously injured and slaps the boy. The butler explains that Rill needs to first understand others so that they can understand him, and then suggests that Rill join the Magic Knights and show off his magic at its greatest.
Walter follows Rill to the Royal Knights Selection Exam, and after Rill reveals himself, Walter is impressed by how he introduces himself, and then threatens the other Magic Knights. Seeing Rill greet Asta, Walter offers the boy a cup of tea, thanking him for being Rill's friend.
During the final match, Walter worries for Rill when Yuno activates his Spirit Dive. When Rill accidentally destroyed the crystal he was protecting and lamented his loss in the final match, Walter comforted Rill and encouraged him to learn from his mistakes and improve himself further.
