Agnes VonStrupp's eldest son. He was to be the recipient of the feathered stick that was involved in the Miracle of Agnes VonStrupp. When his mother died, he inherited the stick and became the first bishop of Reform Wangism.
Gunter was reportedly very upset that his youngest sister, Amelia VonStrupp, reported their mother lied about receiving the Miracle. He spent most of his life attempting to convert his sister, but with little success.
Little is known about Gunter's death. The only information available in records refer to "a ball of string and an enraged mountain gorilla."
