Kogoro Akechi is a protagonist in the anime series Rampo Kitan: Game of Laplace. He is depicted as a brilliant young detective of around seventeen years of age who holds a special government license that grants him permission to investigate cases the police are unable to solve. This official status allows him to operate outside the typical school system, which he has permission to leave in order to focus on his investigative work. His personality is marked by a cynical and anti-social disposition. He is an individual who prefers solitude and the company of his computer and intricate puzzles over social interaction. He is frequently seen opening canned coffee, which appears to be a habit, and he suffers from chronic headaches that he manages with medication. His behavior can come across as eccentric, and his thinking is highly analytical, often relying on cold logic and razor-sharp reasoning. Akechi's motivations are deeply tied to his past, particularly his involvement with a case known as the original Twenty Faces incident. He is haunted by a mathematical formula that was created to predict human behavior and the fallout from that event. This drives him to prevent the resurgence of the Twenty Faces phenomenon and to grapple with the guilt he carries from his past failures. His personal motivation is often tested as he faces choices between pure logic and the value of human life. Within the story, Akechi serves as a mentor and guardian figure to a middle school student named Kobayashi, who becomes his assistant. He recognizes in Kobayashi a similar lack of social integration and takes him under his guidance. Their relationship is a central part of his role, as Kobayashi begins to find purpose in solving macabre mysteries under Akechi's tutelage. Key relationships shape his journey. His past includes a close friendship with Namikoshi, who was the original creator of the Dark Star formula related to the Twenty Faces legacy. This bond was broken by trauma and conflicting ideologies, and Namikoshi returns as a significant figure in Akechi's present. Akechi also maintains a long-standing professional relationship with Superintendent Hanabishi of the police. He encounters various other figures in the criminal and investigative world, including a thief named Black Lizard and a master of disguise known as Shadow-Step, who become recurring contacts. Akechi's development throughout the series is driven by his confrontation with the Twenty Faces legacy. He begins as a detached and cynical prodigy, but his exposure to cases and his connection with Kobayashi force him to confront his own emotional detachment and the consequences of his past actions. His arc culminates in a choice that determines the future of the Twenty Faces phenomenon and challenges his commitment to pure logic. His notable abilities include his exceptional intelligence, deductive reasoning, and analytical skills. He is a genius detective capable of solving seemingly impossible cases that baffle law enforcement. He also possesses knowledge of criminal psychology and a talent for understanding intricate systems of behavior. His reliance on logic and data, as exemplified by the Dark Star formula, demonstrates a methodical and scientific approach to crime-solving. He also exhibits a measured and calm demeanor even in dangerous situations, reflecting his control and focus.
