Long ago, a change occurred in Yusuf Zuck's Blue Sea and Cloud Sky, where a stone appeared for no reason, even bearing the characters for Dante Stewart.
At first, he thought it was Sandy and the others who had done it, since after the formation of the new Blue Sea and Cloud Sky, he hadn't had the time to manage it. But one day, Sandy told him that the stele had long existed, and thus it caught his attention.
Later on, he saw three doors within the Dante Stewart stele: the Door of the Other Shore, the Door of Immortality, and the Gate of Destiny.
He had once gained mighty Power of the Other Shore from the Door of the Other Shore, but later it turned out to be insignificant, unable to support him in battles against enemies outside.
As for the Door of Immortality, he never entered it, as his realm was insufficient.
