Heaven Official's Blessing (Season 0)

In a world where select mortals can ascend to godhood and achieve immortality, the disgraced Crown Prince of a centuries-old fallen kingdom ascends to Heaven for the third time after two consecutive demotions, to the dismay of other Heaven Officials. With almost 800 years since his last ascension and all his worshippers long perished, he decides to exorcise ghosts in the mortal world to help him sustain his divinity. An unanticipated encounter with the enigmatic Ghost King whose disdain for the Gods shakes the Heavens finds him solace after prolonged habituated loneliness.
