The World’s End, and I’m a Little Overpowered. So What?

(System + decisive killer + supernatural powers + no CP + zombies + not a saint + self-interest + dual perspectives) Tycoon System VS world-weary girl × aloof System VS funny girl Think she carries a string of Buddhist prayer beads everywhere because she follows Buddhist teachings and believes, “Buddha’s mercy saves all living beings”? Don’t make me laugh. The beads are only there to restrain her true nature. Without them, you’re the ones who’ll die. When others are falsely accused, they prove their innocence by dying. She proves hers by killing whoever framed her. Of all people to provoke, they had to pick her. Now those clueless fools can just die. With the prayer beads in hand, she’s perfectly normal, no different from anyone else. Once they’re off, your fate is anyone’s guess. If the beads snap, you’ll be covered in blood before they hit the ground, and breathing your last by the time they land. A meteor crashes into City C, causing enormous casualties. The shelters people count on as lifelines are full of people, but are they alive or dead? Why is the military covering things up? What exactly are they hiding? Blood rain falls again and again. Those who get drenched start running fevers, and hospitals of every size are packed with patients. The sudden outbreak catches everyone completely off guard. The feverish begin to mutate. The apocalypse has arrived. What will become of humanity?
