A world abandoned by the gods, mystifying cosmic forces, unimaginable power for those willing to ascend, and a hero who would rather . . . go fishing???When summoned to a fantastical world and granted powers by a broken System, most freshly minted protagonists would strap on their big-boy boots and get ready for their stats to start climbing. But Fischer isn’tlike most MCs. In fact, he doesn’t want to be a hero at all.Fame? Fortune? Power? He had enough of all that in his old life. Discovering forbidden fishing techniques and petting every cute animal that comes within scritching distance? Now that’s a good time.Unfortunately for Fischer, cosmic forces rarely care for mortal feelings. He’s hounded on all sides by inept cults, conspiring nobles, and more magical misunderstandings than those of a preteen relationship. Even his dutiful pet crab is firing energy blades like an anime antagonist.So grab your fishing rod, fetch a good snack, and pet your dog for me. The catch of a lifetime awaits!
