Puzzle & Dragons X

Dragons, once thought to be nothing more than the stuff of ancient legends, have begun to awaken all over the world, changing the familiar course of things. A young dragon caller named Ace has seen mysterious bubbles ever since he was a child, and they help him make the right decisions. However, his ability was limited to finding tasty food, and he had no idea how to use it to its full potential.

Everything changed when Ace met Lance, another dragon caller with similar powers. This meeting turned Ace's life upside down: he came face to face with mystical creatures, took part in battles with dragons and discovered new sides of the world whose existence he had never even suspected before.
