Isekai All-Purpose Supermarket

Han Ji-oh, the owner of a neighborhood general store, discovers that a kitchen knife has opened a portal to another world. He begins traveling between that world and his own, using a subspace to sell goods in both places and earn money. Ji-oh’s modest ambition is to make enough to own a building and live comfortably. Instead, he is drawn into a hero’s party and tasked with preventing the Demon King’s resurrection. His dimension-hopping business venture becomes a commercial adventure across two worlds.
