Thrust into the world as an F-class Hunter, the protagonist harbors an extraordinary secret: an alien consciousness from an advanced magical civilization now inhabits a human body. Plagued by an inability to control his facial expressions, his perpetually stoic appearance breeds endless misunderstandings among guild members and fellow hunters who mistake his indifference for coldness. As he ventures through treacherous dungeons and battles mysterious foes, his lack of human customs combined with sealed latent powers creates comedic situations that contradict his genuine determination and tireless work ethic. Caught between a weak physical form and the weight of his past life's knowledge, this misunderstood reincarnate must navigate a world that constantly misconstrues his every action—transforming each obstacle into both humorous chaos and heartfelt struggle.
