An orphan who grew up at the orphanage in Starkberg. He has a cheerful, carefree, optimistic attitude. The orphanage was attacked by monsters, and rescued by Wein and Maximillian under Logan's orders. Hans helped to rescue the children, and was inspired by Wein to become a strong fighter. He followed them to the west ruins, tagging along in the battle uninvited. Max told him to get formal training as a soldier if he wanted to keep fighting, and Hans did so.
He enrolled in the military academy and half a year after the war between the three kingdoms ended, he was assigned under Wein along with Charlone. His scholastic ability was poor but his practical skills were excellent. From then on he accompanied Wein and they fought many battles together. Hans became very loyal to Wein and was willing to follow him anywhere. Hans and Charlone were often at odds with each other because of their different personalities. He accompanied Wein steadfastly in the fight against Wolfgang, Gevas, and eventually Maximillian.
As an orphan, he looked after the younger children in the orphanage. He used to steal potatoes from a farmer to feed them. He loved to help children and dreamt of having a loving family of his own someday. He often visited Clain Village and looked up to the chief Zemekis as a grandfather. He was upset at the fact that Zemekis was murdered, and detested whoever the murderer was. He vowed to kill the murderer if he found out who it was. Later he found out that Xenos was the murderer, but he forgave him.
