“[Garbage] you are not my son. Disappear like that — you garbage!” A world where those who turned 15 are given skills and suitable occupations from the goddess. Lambda Ancient, a boy born into a distinguished family of knights, was given the unsuccessful job of [garbage fishing] and the unsuccessful skill of [garbage picking] by the goddess. Infuriated by this, his father treats Lambda as “garbage” and banishes him. Losing both dreams and hopes, Lambda was in despair, but when he stumbled into the ruins by chance, he discovered an “artifact”, a relic of a super-civilization that boasted of its prosperity tens of thousands of years ago. It turns out that the skill [Garbage Pickup] that Lambda acquired is the only skill that can completely handle artifacts that have been discarded as garbage. And Lambda, who became an adventurer with Noah, a girl from an ancient civilization he met in the ruins, quickly stands out by making full use of the threatening artifact that led the former super-civilization to collapse. This is about a boy who was banished and called a “garbage hunter”. He rises up the ranks with his friends who adore him, defeats the world’s most powerful men one after another, and eventually awakens to become the world’s strongest knight. And a heroic tale that surpasses even the god who created the world.
