Eight years later, he is made aware of his father’s secret identity; a famous international criminal known as International Criminal 1412: the Phantom Thief, and that he was murdered by a mysterious organization for refusing to aid them in retrieving the Pandora Gem; a mystical stone said to shed a “tear” during the passing of a particular comet, the consumption of which bestows immortality. He vows to prevent the organization from gaining immortality, and assumes his father’s thief identity as he begins his quest for the gem.
