Hirotaka, a former junk collector transported to another world, is bestowed with the "Junk Collection" skill. Initially dismissed as useless because it merely retrieves random discarded items from across the globe, this ability leads to his expulsion from the hero’s party. Left to wander alone and facing desperate circumstances, Hirotaka unexpectedly acquires Osoro, an overpowered magic sword that was abandoned even by the Demon King. Now armed with this legendary weapon, the free-spirited adventurer embarks on a heartwarming and humorous journey alongside the world's forgotten relics, determined to prove the true value of what others have cast aside.
