A man as dignified as he is passionate about his food, Kurtz is a cook that you can bring into your HQ to help cook for your other teammates. When you first meet him in Eiyuden Chronicle: Hundred Hero he is trying to find a recipe he wants to try to master.
When you're in Hishahn, you'll see this man in a fancy black and gold chef's outfit outside of the Smithy. Interact with him and he will tell you he's looking for a Grilled Tutuva recipe. This is found in the Treefolk Village and will be given to you by a treefolk person by the Trading Post. Once you have it, return to him and interact again to recruit him.
Role: Support
Support Skill: Food's Up! - Cook for the whole party before combat.
While at your HQ, Kurtz opens and runs a restaurant (once you build it at the Drafting Studio) inside the Inn. Here you can ask Kurtz for meals and they will give buffs or healing.
