Eyes are the windows to the soul. For Vincent Kuroda, the phrase couldn't be more literal. Since birth, Vincent could look someone in the eye and determine the darkness of their soul: their wrongdoings, darkest hungers, and capacity for evil. After investigating an underground massacre for the Central Legion gang, Vincent is baffled when he encounters an NCA (National Crime Agency) Officer-Jerrod Hains-with the purest soul he's ever seen. He is intrigued to know more about the officer until Vincent witnesses him commit a murder with his soul unspoilt. Wanting to understand Jerrod's mind, Vincent attempts to pursue him. But as crimes in the city rise the more he digs, he questions the perpetrator behind the increased activity until he is hunted. Using the streets of London as their stage, the two will challenge each other until one is imprisoned or dead.
