The anime series, Mix Masters (also known as Mix Master: King of Cards), was jointly created by Korea and Japan, with Nippon Animation, Sunwoo Entertainment, and KBS collaborating for production. The story centers around Mix Master, a card game that transforms from a video game to the real world due to a scientific experiment's malfunction. This sudden shift leads to various incidents caused by the henches (the game's creatures), and the Mix Master card players have to deal with its aftermath. However, Prince Brad, a video game antagonist, creates more problems with his uncertain motivations.
