Luo Wei is a peace officer in Qicheng. He has a Duel Disk that lets him use cards to transform into characters from games and gain their abilities.
One day, after bringing an ability user who was a thief back to the peace officer headquarters, his superior told him he had gained a new subordinate named Kiana. From that day on, characters from games began appearing in this world one after another.
Then one day, he ran into his older sister. From her, he learned the truth: this world was fake, a world that existed only in fantasy.
