Sinbi Apartment: Ghost Ball X-ui Tansaeng

After the danger beneath Sinbi Apartment is defeated, Hari and Doori hope their ghost-filled days might finally calm down. Instead, a dark curse begins drawing stronger spirits into their lives, and even the Ghost Ball they depend on is no longer enough to face every threat.

A new Ghost Ball X gives the siblings greater power, but the mysteries around them also deepen. Kang-lim is troubled by an unknown force within himself, while a mysterious boy named Leon appears with his own connection to the supernatural. As new ghosts emerge, the group must uncover what is feeding the darkness before it consumes more than their apartment.
