Shihoko Kishida (岸田 志保子, Kishida Shihoko) was a Contractor working for the Syndicate who was tasked with lengthy undercover missions, which includes the assassination of Alma. Years ago, she was tasked with assassinating Isozaki, Huang's partner when the two were detectives, after learning that he was linked to covering up the murder of one of the Syndicate's operatives. In order to get close to Huang to figure out which of the two was working for Alma's organization, she stole his wallet from him in a shop. When he tried to apprehend her, she snuck the wallet back in to his pocket and was struck by a car and hospitalised. She covered up Huang's apparent mistake over the wallet. Over the following weeks, Huang grew close to her until one night, when Huang was really drunk, she asked him about a photo that he and Isozaki had previously found. She then left him and she subsequently killed Isozaki as Huang was leaving his partner's house
Darker than Black
It has been 10 years since Heaven's Gate appeared in South America and Hell's Gate appeared in Japan, veiling the once familiar night sky with an oppressive skyscape. Their purposes unknown, these Gates are spaces in which the very laws of physics are ignored. With the appearance of the Gates emerged Contractors, who, in exchange for their humanity, are granted supernatural abilities. In the Japanese city surrounding Hell’s Gate, Section 4 Chief Misaki Kirihara finds herself at odds with an infamous Contractor codenamed Hei. Called "Black Reaper" in the underground world, Hei, like his associates, undertakes missions for the mysterious and ruthless Syndicate while slowly peeling back the dark layers covering a nefarious plot that threatens the very existence of Contractors. From the mind of Tensai Okamura comes a sci-fi thriller taking the form of a subtle exposé on a war in which political positions and justice have no sway—a war waged exclusively in the shadows.
