My Useless System Has Crashed Again

A genuine nobody extra and a discarded System.

When other people are cannon fodder, they at least get to be supporting characters or villains. But when she is cannon fodder, all she can do is play an extra and blend into the background. She is not even worthy of a name.

The Systems other people encounter can at least issue missions and help them fight monsters and level up. The System she encounters has a bug, has been discarded, and vanishes without warning.

Warning: The protagonist has arrived!

For cannon fodder, being around the protagonist is like being beside a tiger. Her task now is to break free from her destined death as cannon fodder and escape the plot's fatal twist.
