The three goddesses of Glynn's World have a wager. Whoever summons the hero that defeats the Great Devil and saves Glynn's World from corruption will be made Supreme Goddess. Rani has twenty-four heroes at her disposal. Elbeth has summoned thirty. Marine? She has one hero. Eh, more like half of one.

Dige has several advantages over others, such as dwarven strength and a knack for forging, but he's also loud, stubborn, barbaric, single-minded, smelly, murderous, repulsive to humans, and worst of all, has zero knowledge about the world and how to be an Isekai Protagonist. If left to his own devices, he'd stay in his mountain hole forever, but a black coated swordsman, Akira Kasuga, puts the dwarf on the path to greatness by killing him in cold blood and securing his name in Dige's Book of Grudges.

With his second death, Dige sets out on a quest to kill Akira. Whether that leads him to killing the Great Devil, who's to say? But it means that Marine isn't out of the wager just yet.
