"I just wanted to work in peace... so why is my store being attacked by giant komodo dragons?" Dadang has just graduated from high school. No experience. No job offers. Until one day, he finds a mysterious flyer and accidentally gets transported to another world — Aethelgard. There, he works at a department store run by Aston, a former legendary adventurer. His coworkers? They're retired S-rank adventurers who once saved the kingdom. What's more surprising, the store sells items from various worlds — including Earth. Dadang's life is never peaceful. The store gets attacked by giant komodo dragons. The government hides a dark conspiracy about enslaving survivors from other worlds. And a man named Valerian — an enemy who is actually a victim of the system — gives Dadang a mysterious ring that won't come off. Dadang isn't a hero. He's just a regular store clerk. But sometimes, even a regular store clerk can change the world.
