Roan already understood that the demons' realm was also the Underworld. However, he didn't know much about the Underworld on this side of the universe. Well, he also wanted to know more about the angels' realm as well.
Turen nodded in response to that and began to explain. "First, the demons' realm, also known as the Underworld. You said you were a Death Spirit before reincarnating on this side, right? Then, you know that all souls head to the Underworld before reincarnating."
Roan confirmed, replying, "Indeed. My job back then was basically to guide the souls out of their dead bodies to the path of reincarnation, which was located in the Underworld."
