Butler Von Granvelle serves as the head of the influential Granvelle family, which holds dominion over the protagonist Allen's hometown and the surrounding territories. As a ruling lord in this world, he occupies a position of significant authority and social standing. His physical appearance is distinguished by purple hair that falls to his neck and striking red eyes, with a beard that gives him an air of maturity and seniority.

The character embodies a dual nature, balancing the formal responsibilities of a noble lord with the personal warmth of a father to his own children. His personality reflects this careful equilibrium; he is someone who can be relied upon in times of need, providing a sense of security and stability for those under his care. While he maintains the dignified composure expected of his station as the Granvelle family patriarch, he does not hesitate to show a more personal and caring side when interacting with his family members.

Butler's key relationships are centered around his immediate family. He is the father of Mikhail Granvelle, the eldest son of the household who is known for his solid swordsmanship and humble, gentle nature. He is also the father of Thomas Granvelle, the second son who possesses a somewhat selfish personality. His connection to the protagonist is that of a liege lord to a serf, as Allen is born into a family of servants living under the Granvelle family's rule. In terms of notable abilities, specific combat skills or magical talents are not prominently detailed in available sources; his primary capability lies in his political authority and the administrative management of his domain. The character is featured as a member of the main cast and appears throughout the anime series.
