Ever since his encounter with Aruer way back in the Hidden Library, Nash made sure to always keep his eyes on his bracelet to see if perhaps he accidentally don't get close to a Soul Fragment.
He inspected the bracelet during his time in Planet Gaia, inside the Ancient and Slayer Dimension, and even when he was teleported to the unknown hall of the Ancient One!
However, unfortunately, although he checked his bracelet from time to time, deep inside Nash knew quite well that finding Aruer's Soul Fragments would not be as easy as just visiting a few dimensions and he will be crossing paths with them.
No, not at all.
Nash knew that he had to try way harder than that as even Aruer himself didn't know where his Soul Fragments really were. Unfortunately, when he saved all the humans with one of his powers, as a backlash, his soul was split and scattered, unknown where they have gone.
