A continent appears overnight and nobody knows what lives there. The show watches exhausted relief workers pull other people out of the water instead of chasing glory themselves. It finds something sharp in that gap: the real cost of exploration is paid by the people nobody remembers, and the show remembers them.

A new continent called Magmell suddenly rises from the ocean, and a new age of exploration begins. Explorers pour onto its shores in search of lifeforms and resources no one has seen before, but they run into one disaster after another. To keep the expeditions going, specialists known as anglers handle the continent's dangerous wildlife. Inyou is one of them, a skilled and seasoned angler who carries out search and rescue missions for clients alongside his assistant, Zero. Based on a manhua, the result is an action adventure fantasy about the relief workers who earn their living aiding explorers on this unpredictable frontier.
