This Japanese animation is a sequel from City Hunter. A young Taiwanese professional assassin codenamed Glass Heart committed suicide by jumping off a building, and her heart was pierced by a metal fence. After the accident she was hospitalized and miraculously her life was saved by heart transplantation. During her recovery she began to experience strange dreams she saw a glimpse of memory, which led her to Japan looking for the donor of her heart, who happens to be Kaori Makimura, former partner of City Hunter. Personally I’m a big fan of City Hunter manga because the story is very funny, the City Hunter Anime is interesting too but I don’t like what happened to Kaori Makimura in this Angel Heart Anime, but I keep watching Angel Heart to see the continuation of the story and plot.
