Zarek didn't look back a single time, his pace only increasing as he continued to run.
He didn't make mistakes often, but at the end of the day he was human. What separated him from others was that he knew how to cut his losses.
The way he saw it, no one would dare to use the badge for several months at the very least. There was even a good chance that those chasing after the badge were actually just trying to play defense.
Fighting against an S Class, even with the advantage of one attack, was far too dangerous. There was no one—not even amongst these geniuses—that could guarantee they could kill an S Class with one strike. And if you didn't… well, you'd find yourself facing off against a very pissed-off S Class.
There were good rewards for not only completing this challenge, but being the first to do so. Most of the Demons, if not all of them, planned to quickly gain the strength to kill A Classes, then carefully pick out their best matchups before taking them down one by one.
