Angel Heart is the sequel to City Hunter, but it upset fans of Kaori and Ryo so much that the author eventually called it an alternate universe story.

The story follows Shanin (or Xiang Ying), a young female assassin whose code name is "Glass Heart." She tries to kill herself in the beginning of the story, but fails. Instead, she receives a new heart: Kaori's heart. Kaori, who was preparing for her wedding with Ryo, was killed by a truck as she was saving a young girl. Through Kaori's heart, Shanin can hear hear and see Kaori. Shanin tracks down Ryo, who adopts her as his daughter. Entering into this are other assassins from Shanin and Ryo's pasts.
