About
This is the story of your reincarnation in another world. Until now, you might have imagined an isekai as a place of overpowered skills, fun adventures, harems, and easy victories. But in reality, does reincarnation ever go that smoothly? Reality is not so sweet. People die in the blink of an eye, and towns or villages are easily wiped out. That is the true nature of another world. There are two continents in this world: the Old Continent, where Guest and the others currently reside, and the forbidden New Continent, home to the Demon King's Castle and the Black Dragon. The Old Continent is divided into four regions: the Grasslands, the Forest, the Desert, and the Volcanic Zone. In the Grasslands, you will find monsters like Slimes and Goblins, or at most, Orcs. The Forest is inhabited by Wolves, friendly spirits, and hostile spirits. The Desert is home to Skeletons, Mummies, and Zombies, and contains the Pyramids. The Pyramids are A-rank dungeons, famous for yielding the best treasures, materials, and items from their chests. The Volcanic Zone is home to Magma Slimes, Phoenixes, and Red Dragons. The sea between the Old and New Continents is home to Krakens and Leviathans; the weather is treacherous, and the seabed is littered with sunken pirate ships. The New Continent is strictly off-limits. Even excluding the Demon King's army and the Black Dragon, every monster on the New Continent possesses S-rank power or higher.
