Twin Sword Vagabond

by Momonga Iris

A cleaner with less-than-explorer qualifications picks up a mythic-grade sword. Two of them, no less. In 1999, the great King of Terror never fell—but the world merged with another realm, and magic, otherworldly races, and dungeons appeared on Earth. A quarter century has passed since humanity weathered the great chaos of the "World Fusion" and learned to build new lives around the resources that dungeon explorers bring home. People have come to enjoy dungeon exploration streams, and the explorer has become the most popular profession in the world. Explorers dive into dungeons, return all manner of resources to society, and fulfill the vital duty of keeping "labyrinth rampages" in check by conquering the depths. Merit-based explorer clans, idol-popular all-female clans, stateless bands wandering the globe... And somewhere in this society, Hayasaka Toru works as a cleaner at his local dungeon. Those judged to have no labyrinth aptitude can never become explorers. But leaving unpopular dungeons untended only raises the risk of a rampage—so cleaners are hired to cull small fry, restricted to the upper floors of the municipal D-rank dungeon. For some three years, Toru has spent every single day hunting small fry on those upper floors. Then, through some fluke, Toru runs into a dungeon anomaly and steps on a teleport trap. Fierce monsters prowl there that belong nowhere near the upper floors of a D-rank dungeon—and in a hidden room he flees into for his life, he finds mythic-grade swords plunged into the floor. Two of them. This is the story of a bottom-rung cleaner who ended up holding a holy sword and a cursed blade in a modern-day dungeon.
