The story of Duel Masters King entered the "next stage" with the new series. The theme of the new series is "time travel."
The protagonist, Joe Kirifuda, loves drawing pictures and playing Duema. He creates Deckie, a talking deck case with the ability to create creatures, and his sidekick Jokers, and challenge his rivals to duels. Joe is now a sixth grader, and although he's grown up a bit, he still enjoys playing Duels with his friends. Joe and his friends live in peace. Abaku, the man who became enchanted by demons and became a demon, appears again. What exactly is Abaku's purpose...? Joe's story is about to reach its climax.—Duel Masters Wiki
