Also known as: Glück, グリュック
Glück is the Feudal lord of the Fortified City of Weise. He is the father of Lektüre and thus the father-in-law of Denken (Sousou No Frieren). He made a deal with Macht (Sousou No Frieren) about a hundred years ago to set up an experiment to help him understand humans and had Macht serve him as the family's mage.
