With the surprising arrival of a new continent known as Magmell, a new age of discovery starts. Magmell's immense treasure of hitherto unseen natural riches encourages exploration of its wide area. The unknown, on the other hand, is not necessarily meek. People known as "anglers" specialize in dealing with Magmell's deadly animals in order to sustain the excursions. Inyou, a highly talented and experienced fisherman, executes search and rescue missions for clients with the assistance of his helper, Zero.
