SSS-Rank Warden of the Uncanny

Transported into a world where supernatural horrors have returned, an ordinary man begins with nothing but terrible luck and a mysterious system. By drawing and mastering the abilities of the very creatures hunting humanity, he transforms himself from the most miserable newcomer alive into an SSS-rank prodigy. As his powers grow, he enters the Four-City Ranking War and shocks every major faction. But each new ability brings him closer to the source of the paranormal outbreak—and to a responsibility far greater than simply surviving.
