Lucian never expected anything exciting to happen during his boring late-night shift at a convenience store. One moment he was watching funny animal videos and counting the hours until morning. The next, the world outside the store vanished into endless darkness—and a mysterious system awakened inside the shop.

The Multiverse Merchant System.

Now the store exists between worlds, acting as a hub connected to countless realities—anime worlds, movie universes, and TV show dimensions. As the system’s chosen merchant, Lucian gains the ability to travel across these worlds, collect rare items, influence events, and trade powerful artifacts through his shop.

But Lucian isn’t a conqueror or a villain.

Despite the chaos surrounding him, he remains the same person he’s always been—kindhearted, sarcastic, and surprisingly calm in the face of impossible situations. He refuses to harm innocent people and prefers helping others whenever he can… even if it means accidentally changing entire storylines.

As the Son of Gaia, Lucian carries a mysterious connection to the living world itself—an ancient lineage that even the system doesn’t fully understand.

With a strange vampire girl named Elena becoming his first customer and companion, Lucian begins traveling through different worlds, collecting powerful items, forming unexpected alliances, and slowly building the greatest shop the multiverse has ever seen.

But the more worlds he visits, the more one truth becomes clear:

Some stories aren’t meant to be changed.

And the moment Lucian steps into them… everything begins to shift.
