Ryota Sato barely survives his first encounter in another world, nearly beaten down by the young adventurer Emily Brown before he understands where he's landed: a place where monster hunters live off whatever loot their kills drop. His character level turns out to be permanently stuck at 1, leaving him without the usual growth every other adventurer relies on, until he discovers a unique skill that guarantees rare item drops from anything he defeats. This manga adaptation follows Ryota as that one working skill starts to change everything.
