A Parasite's Life in the 1970s

An orphan girl suddenly becomes the master of a spatial dimension, and because of this dimension, she lives quite well in the apocalypse. However, she is feared by those in power, framed, and ultimately perishes along with her family.

Waking up to find herself transported to the 1970s, she has a reborn older sister, and thus begins a life of leisure and indulgence.
