Underworld Invasion

A massive war erupts between angels and aliens, with the very fabric of the afterlife at stake. Kim Ria, the last surviving human on Earth who has no lingering attachment to life, and Azazel, an angel who despises the god exiled from the afterlife, become the pivots upon which the fate of both humanity and the afterlife turns.

In the afterlife, angels and aliens clash into an all‑out war. At the same time, on Earth, Azazel and Kim Ria undertake a tense survival adventure as they evade pursuit squads hunting the final human.
