In the late 19th century, as the cruel times of the Bakumatsu period came to a close, a new Meiji era marked the age of restoration for Japan. With the war over, its infamous hero Hitokiri Battousai disappeared into thin air, leaving only his legend behind. Years later, a seemingly plain wanderer named Kenshin Himura encounters Kaoru Kamiya, the owner of a struggling local dojo in Tokyo. Kaoru pursues a self-proclaimed Battousai who roams the streets, indiscriminately killing citizens and police officers. Furthermore, the warrior professes to use the Kamiya Kasshin-ryu—a sword style developed by Kaoru's father deeply rooted in the essence of life, not death. Kenshin decides to help Kaoru take down the impostor and restore her father's dojo. Unbeknownst to all, Kenshin is none other than the real warrior whose name still terrifies the people. Although Kaoru eventually learns the truth, his oath to atone for his murderous history by bloodlessly protecting the weak moves her, and she welcomes Kenshin to stay at her dojo. However, Kenshin's ideals are soon challenged by ghosts of the past and enemies of the present.

Although most gods in the heavenly realm avoid dealing with the forgotten god Xie Lian, Heavenly Emperor Jun Wu holds him in good graces. Xie Lian's luck is otherwise terrible, and adding to his troubles, the gods seem to suspect that Xie Lian's recent companion was the dreaded Ghost King Hua Cheng. Despite what others may think of him, Xie Lian fondly recalls Hua Cheng's promise: the next time they meet, Hua Cheng will appear in his true form. Jun Wu informs Xie Lian of the unsettling news that a god's distress signal was seen coming from the Ghost City—the most prosperous place in the ghost realm, where the only law is Hua Cheng himself. As Xie Lian has no qualms about stepping into Hua Cheng's territory, he infiltrates the city to locate the lost god. There, the genuine Hua Cheng is already waiting. He is the most feared being across the three realms, yet before Xie Lian, his arrogance erodes. Without revealing the reason for his generosity, he spares no power or means to ease the burdens of Xie Lian's endlessly unfortunate past.
