"I wonder if they're back", Ace thought as he remembered that he hadn't met any of his teammates for quite some time now.
For one, he doesn't even know if they are still alive or not, and the only person whose contact was with him was Anna, and she's usually the first to send a message whenever she's in the true world, but Ace did not receive any today, which meant she either had to be very busy with whatever she was doing in the true world or she wasn't even in the true world and was in another dimensional space like the alternate dimension and dungeons.
Either way, her name was still on his contact list and he had sent a message to her immediately after covering his traces as he went down the stairs to the real entrance that would lead him into the alternate dimension, his home.
