Story
Lux-Pain is set in the historical city of Kisaragi, a city plagued by everything from small mishaps to murders - without a logical explanation as to why these events happen. It seems that "Silent", a worm created by hatred and sadness, has infected people, forcing them to commit gruesome crimes. Atsuki's parents are the victim of such crimes. To avenge his parents, Atsuki undergoes a dangerous operation to get Lux-Pain in his left arm, a power so strong that it turns his right eye golden when he uses it to search for and finally destroy Silent.
