Stark is a young warrior boy who joins Frieren's journey after being taught by the dwarven warrior Eisen, a former comrade of Frieren. As a disciple of Eisen, Stark wields an axe and initially shows signs of cowardice or hesitation in battle, but he overcomes his fears through encouragement and determination. He travels with Frieren, Fern, and others toward the resting place of souls, contributing his strength to the party while developing personally along the way.
