The ZZZ-Rank Rebel: My Evil King Skill is OP

In a world where humanity is granted extraordinary powers known as "Divine Blessings," Kyo Yasujima was cursed with nothing.

Once ridiculed as the "Weakest Rank ZZZ," Kyo has now been reborn as the "Strongest Rank ZZZ"! Armed with an overwhelmingly powerful and exclusive skill, his epic rise from the absolute bottom begins now!
