Yael Lynch, a ghost trapped in an apocalyptic world, struggles with a persistent system that insists she is human and must join the Federation to rebuild civilization. Despite insisting she is no longer human, the system pressures her to comply. Meanwhile, Yael encounters a zombie who questions why he should attack her when they share a similar undead state. Frustrated and unwilling to be preyed upon, Yael decides to turn herself in to the authorities at Prosperia Base before the zombie or others can harm her. Her fate after surrendering remains uncertain.
