Reincarnated otherworlder Makoto Takatsuki is an apprentice mage with lackluster skills and stats, but when he is recruited by the goddess Noah, he becomes her sole believer. There's just one caveat—Noah is actually a wicked deity! Along with his fellow mage Lucy, Makoto has been making a name for himself as an adventurer, taking down everything from ogres to griffins. After nearly a year in this new world, Noah finally offers Makoto a helpful revelation: a "fateful encounter" awaits him in the Great Maze Labyrinthos. He enlists the support of his best friend Fujiyan to tackle this vast dungeon, but before long, Makoto and Lucy are attacked by a dragon! When the floor of the dungeon collapses, the pair find themselves stranded deep underground and surrounded by high-level monsters that are eager for their next meal. Is this what a game over screen looks like? And when all seems lost, can a "fateful encounter" save Makoto from a bad end?
