What if the Origami Warrior, which is known as an intriguing paper-folding craft, is the product of an advanced science from an ancient civilization that disappeared before human history began?

What if you can fold paper anyway you want through your imagination and make it come to life? The "Black Union" already learned that the ancient "Origami Warriors" ruled the world by summoning "Origami Spirits" which gave them the paper-folding technology, "Origami." The Black Union creates a popular game called "Origami Battle" in Neo City, and they try to search for the secrets of the ancient civilizations by having people play the game.

Jichol wants to become a top player in the "Origami Battle" game, but he is never able to pull off a win. Nevertheless, he doesn’t lose hope to reach his goal.

One night, a mysterious man named "Dalguk" appears before Jichol. He is badly wounded and gives the "The Secret of Origami" book to Jichol to fight unknown monsters that attack them. When Dalguk’s life is in danger, Jichol summons the most powerful Origami Monster and saves Dalguk’s life. But Jichol doesn't remember anything after summoning the Origami Monster, and Dalguk believes it is better to not tell Jichol about the incident for his own safety. One day, Jichol and his friends stumble upon a clue about the secrets of the Origami Warrior. So they decide to search for the secret and also learn about the evil conspiracy led by the "Black Union."

The search for clues to the secret by Jichol and his friends begins out of curiosity... As they realize that they must stop the "Black Union," the children take action and gradually grow into stronger "Origami Warriors."
