Apocalypse: I Can Predict Death, Except My Own

[Apocalypse] [Zombies] [System] [Deduction]

On the tenth day of the apocalypse, I awaken an S-rank ability, [Death Premonition]. I can see anyone's death and its exact time, but I can't see my own.

The System tells me: Four days from now, I'll die at the hands of "X."

I spend four days investigating X's identity, but every clue points to my best friend.

On the fifth day, I die.

Luckily, this is only a vision of the future that I bought with all my points.

When I open my eyes again, the System's message has changed:

"X wasn't the one who killed you."

"This time, you only have one chance."

I clench my fists.

Fine, fine... If I can't find the real culprit this time, I don't mind using the all-purpose method of elimination.
