Yusuf Zuck departed from the Pier Dojo, but before he left, he once again placed Ruth Wilcox and everyone else into the Blue Sea and Cloud Sky.
This time, he left alone, without bringing Big Black Dog or any of the Masters, because he didn't want anyone to know his whereabouts.
Also, this time, he planned to settle his family in the Mortal World.
If in the future he survived and could dominate the world, he could bring his family back anytime, but if he died, at least they wouldn't be implicated by him, and they could enjoy life safely.
Of course, this was his worst-case scenario, a sort of arrangement for after his possible demise.
However, as he ventured alone away from the Pier Dojo area and had even entered the Southern Area, an unexpected situation disrupted all his original plans.
He left Pier Dojo quietly, and except for Pier, no one knew when he had left. He hadn't taken the sky route but left from underground.
