The protagonist, Kikuru Madan, is a skilled adventurer who initially aspires to retire from his dangerous profession due to the physical toll it takes on his body.

Despite his reluctance, Kikuru agrees to mentor her, forming an adventurer's guild.

The narrative explores the dynamics of their guild as they take on various quests, often involving battles against monstrous creatures. Along the way, they are joined by other members, including a healer named Hanabata Nohkins and a mage named Hitamu Kyan. Each character brings unique abilities and personalities to the group, contributing to both the comedic and action-driven aspects of the story.
