Biography
Eisen ｢アイゼン Aizen｣ is a dwarf and the former warrior of the Hero Party that defeated the Demon King, consisting of himself alongside Frieren, Himmel, and Heiter. As a dwarf, he has a much longer lifespan than most humans, but a shorter one than elves.
Eisen is a witty and troublesome person, and failing to show respect to the king prior to their adventure almost had him and Himmel executed. Eisen is also known to be rather careless and tough, jumping down from extreme heights without a scratch.
He initially did not believe in religion, and thought of the deaths of his family in a matter-of-fact manner, shown by having them in a mass grave with a simple stone. However, after listening to Heiter say that he wants to believe they are in Heaven because it would be more comforting to the deceased, Eisen adopted the practice of praying at their graves. He has maintained this practice even in his old age.
