The world is overrun with strong adventurers who take what they want and kill what they please. Towns and cities practically spring from the ground these days, and every single one has a guild promoting the genocide of all monsters. Heroes from other worlds are summoned from thin air, and they're all unfairly blessed by Gaia herself. Sun is one of the last remaining cucuy, a humanoid monster race that is almost visually identical to humans. Join him on his quest to restore balance to the world and give even the strongest adventurers a real good reason to look under their beds at night.
