When I Reincarnated Into a World Doomed by Card Games and Opened a Card Shop, Everyone Thought I Was the Protagonist of the Last Story

Ever find yourself dropped into a world where high stakes card battles dictate destiny, and you're just trying to run a humble shop? That's the unexpected reality for our protagonist, who awakens in a world where powerful card games shape the very fabric of existence. With a new lease on life and a knack for all things strategic, they decide to open a card shop, hoping for a quiet, comfortable life away from the grand, world-shaking duels. However, fate, or perhaps just the sheer force of their presence, seems to have other ideas. As they settle into their new venture, an uncanny perception begins to take hold among the locals: could this unassuming shopkeeper actually be the hidden hero destined to conclude the epic saga of this card-centric world? It’s a classic case of mistaken identity, or perhaps, a prophecy waiting to unfold.
