Note: This project began as an amateur manhwa on Naver, but became popular enough that Naver chose to turn it into a professional work. The author and artist changed their pen names and restarted the series from the beginning, redesigning the artwork and part of the storyline in the process.

When she goes to her new school, she encounters a super model that fights with a guy using special power that seems to be the one Jiyoung’ grandfather has been talking. Unfortunately she is involved to their fights involuntarily, and even meets them at her new school. She gets to know they are psychics called Trumps or Cards) who have special talents, mingling with them and she realizes she also has a special power. Is she also a trump or the rule?
