Lloyd serves as the personal assistant mage to Ruby, a genius alchemist and his childhood friend. Ruby constantly berates him, claiming his material gathering rate is pathetically low and treating him as worthless baggage, making him the target of ridicule across the entire country. Unable to endure the daily power harassment and despair any longer, Lloyd makes the decision to sever ties with her and leave.

What Ruby and everyone else fails to realize is that the materials Lloyd gathers are actually incredibly rare, high-grade items that no one else in the world is capable of collecting. His supposed incompetence stems from a unique ability to harvest materials that are simply inaccessible to any other mage or alchemist. Lloyd himself has internalized the belief that he is untalented, unaware of his own extraordinary value.

After walking away from his abusive partnership, Lloyd relocates to a remote frontier town. His primary goal is no longer to prove his worth or seek revenge, but to live a peaceful, slow life far from the toxic environment he endured. The story follows his attempts to build this new existence, though his hidden capabilities and the high-grade materials he can uniquely gather are likely to draw attention and complicate his pursuit of a quiet life.

The narrative is set in a fantasy world where alchemy and magic are established professions, with material gathering being a fundamental skill. The central conflict arises from the vast gap between perception and reality, as a protagonist who has been thoroughly convinced of his own inadequacy gradually discovers his true potential, while those who dismissed him remain unaware of what they have lost. The manga is a serialized fantasy story with elements of romance, comedy, and adventure, published by Kadokawa.
