Duel Masters

S02:E04 - Enemy, Mine

Shobu and Rekuta are still traveling to this magic mountain where Shobu can learn to control his Kaijudo creatures, hopefully in time for the upcoming plot-moving setting known as the Big Tournament. Along the way, they meet a young girl named Charolette who is being harassed by a bunch of thugs. After saving her, Shobu meets up with an old rival, Jamira! Strangely, he's playing Darkness Cards instead of his usual Deck, and the reason is revealed very quickly, he accidentally swiped Kokujo's Deck! Shobu proceeds in cleaning Jamira's clock, and Kokujo explains that something freaky is happening in the mountain where Shobu and Rekuta are traveling.
