Giesela is Günter's adopted daughter and a physician in Shin Makoku. She is a member of the healer tribe so she has green eyes and her blood is green so her skin is a bit of a different colour. While usually sweet and caring, Giesela is strict and commanding when it comes to work. Her attitude toward work and her ability to order people around earned her the nickname "Sergeant". Giesela was adopted by Günter at a young age, and lived with him in the kingdom. She was Julia's aide during the war so she cared for her and cremated her body when she died.
