In a universe where countless dimensions overlap, a peculiar phenomenon occurs: mysterious doors appear, leading to an inconspicuous convenience store. However, the seemingly mundane establishment harbors a world of untold secrets.

Inside, patrons range from immortal cultivators deep in contemplation over the flavor of instant noodles, to ancient demons savoring a cola, and even primordial beasts delicately holding a bag of potato chips. These are no ordinary beings—some could shake the heavens themselves—and yet, in the Dimensional Convenience Store, they all stand quietly in line, adhering to an unspoken rule: even the mightiest must abide by the price.

At the counter, a young man named Vahn scans their items, his presence an enigma. No one knows where he comes from or why he's here, but everyone understands one thing: in this store, no one is above the rules.

Refundus, the Devil of Customer Complaints


He wore a fedora and wielded a stamp that could erase purchases and memories.


He marched to the front, bellowing, "I was promised eternal bliss and a soda!"


Levi Ackerman sliced his receipt arm off mid-rant.


"Get in line," Levi muttered, mopping blood and cola.


The battle raged. Refundus summoned Karen Avatars. Gojo blindfolded them into confusion. Denji chainsawed them into Yelp reviews.


Vahn (now partially restored) teleported in just in time to punch Refundus in the coupon codes.
