Eisen

Eisen is the Warrior in Sousou no Frieren. He was a part of the Hero Party, alongside Frieren, Himmel and Heiter. Eisen is a Dwarf, and so has a somewhat longer life span than that of a Human, however not as long as an Elf's.

Personality
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.

He initially did not believe in religion, and thought of the deaths of his people in a matter-to-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 grave. He has maintained this practice even in his old age.

Appearance
Eisen is a male dwarf with an aggressive appearance due to the red cloak and that he wears over his body and helmet that he always wears. Surprisingly, it can later be noted that Eisen has a rather skinny build.
