Sinbi Apartment: Ghost Ball Z

Hari and her friends continue answering supernatural incidents that spread through Hyunwoo's increasingly popular ghost-story channel. With the Ghost Ball at their side, they confront restless spirits whose grudges and tragedies turn ordinary places into dangerous hauntings, while each case reveals that even the most frightening ghost may be carrying a story that was never heard.

A far more unsettling threat begins moving behind those encounters. A mysterious exorcist with power rivaling even Kanglim's repeatedly crosses the group's path, and secrets buried in old memories pull Hari toward a conflict much larger than a single haunting. As hostile spirits gather and long-hidden truths surface, the friends must rely on one another before the next supernatural battle reaches those they care about.
