Even though Raphael had made a choice, he still felt that Azekiel was going to call him wrong. He expected Azekiel to just say that he wasn't the man who created this tower, but contrary to all his expectations, Azekiel accepted it!
Lia was quite taken aback. She chose to trust Azekiel, only to find out that he was the reason that even their soul was trapped here. So she had been helping their biggest enemy all this while? She should've come to terms with it.
"Is it really the truth? You are the reason we are trapped here?" she asked, clenching her fist.
"Nope. I'm not the reason you're both trapped here. I'm the reason for every soul being trapped here. You two aren't the only ones." Azekiel answered. "Every King who had ever died inside this tower, or every human! Their souls still rests in the Tower and will continue existing as such."
