"It's time to duel!" Very neat and upbeat song. The music can brighten your day alone. Just sit here and listen to it, also smile! ^-^ I love the full version and the little mini version they do at the beginning of each of the episodes.

Skip to 0:58 if you want to hear just the song and not the short little explanation at the beginning.
