After death, before reincarnation, the souls of the deceased transit through a fantastical realm known as, Another World. Gudo is a spirit that helps to guide these transient souls to their reincarnation. While guiding a young girl named Yuri, he learns that humans have emotions that he does not understand. Tasked by Goddess Mira to help Yuri control her rage and prevent her transformation into a monster, Gudo embarks on a perilous mission.

Nothing is ever destined to happen in the nether. Everything is impermanent. When Ghostie, who should have lost traits of humanity, encountered a girl that was reluctant to give up on finding her lost brother, nothing will ever be the same anymore.
