"Then go. We'll be here a few days, there's still time." He squeezes Yugi's hand once more and gives him a smile before slipping back. Kaiba doesn't exactly like the idea of going alone, but he promised he would. And he's been alone most of his life, so it shouldn't be an issue, right? He'll wait for Yugi to depart, watching until he disappears, and then continue to the lifeless place...

The darkness and emptiness are oppressive. He has to stop a few times and remind himself that he's not in danger. Several times he wants to hit the evacuation, but he's too stubborn for that

Be safe, Yugi.
