Big Hit Academy was one of the most prestigious academies all around the world and surely the most prestigious one in Asia. When Park Yumi recieved the acceptance letter she was more than happy. But would she be able to survive in a world of Pures as a Non-Pure? She didn't even know if her own brother would be still as accepting as he used to be, after all, he was Pure.  

CARD Academy was the only place to study at if you wanted to become a Card Master. It was easy to get in, but it was hard to stay. Most students left after a month. Kim Jangmi will stay, whatever it takes. And once she's graduated she's going to prove her parents wrong.
