Reborn in the Apocalypse: The Host Keeps Dying

When the system promised she could ride the protagonists' plot armor to save the world, it forgot to mention one crucial detail—she's just a disposable side character.

But why would a world-saving system bind itself to a low-level supporting character instead of the actual heroes? As reality glitches and the system's permissions mysteriously lock, she realizes this death game runs deeper than anyone suspects.
