At that moment, Aina exited the tower, followed a few moments later by Amery.
Aina had climbed to the 12th floor before running into some bad luck of her own. Well, she had technically run into said bad luck on the 11th floor where she was faced with a skeleton graveyard.
Without any Blood Force to take advantage of, strength at Tier 2 of the Sixth Dimension, stacked with God Path comprehension, was beyond what she could contend with.
In order to cross the 11th floor, she essentially drained herself of all her Life Force, knowing that it was a simulation. But, facing even more undead on the 12th floor, there was really nothing that she could do to contend, leading to her loss.
As for Amery, he climbed to the 10th, clearing it before he directly stopped. It was clear he knew things that Leonel and Aina didn't, so he hadn't even tried to go beyond.
Stepping out, he rose his head to the leaderboards, giving them a once over.
