Kurt is a dedicated member of the Salburg Church who worships the goddess Arutena. He was raised in the church and had a strict upbringing. He has a somewhat rigid personality, but has a great sense of righteousness.
When he learns of Lilie's effort to build a magical academy, he does not agree. Because Kurt sees things logically, he is not a firm believer of alchemy. However, he still offers to assist Lilie for when she goes out to gather materials as that is not alchemy.
