Description
Detective Mitsuhiro Maniwa is introduced as a young and idealistic police detective assigned to the high-profile Lil Slugger case, serving as a partner to the more seasoned and cynical detective Keiichi Ikari. As a rookie in his early twenties, Maniwa is characterized by his neat appearance, often dressed in a button-up shirt, tie, and an open overcoat, which stands in contrast to his partner's rumpled look. Personality-wise, he is patient, kind, and possesses an open-minded and flexible approach to investigation. While his partner relies on traditional interrogation and physical evidence, Maniwa prefers to act as the good cop, speaking gently to witnesses and attempting to read between the lines of the case file to uncover deeper truths.
Throughout the investigation, Maniwa is motivated by a genuine drive to understand the enigmatic Lil Slugger. He is the first to propose that the assailant targets individuals who have been emotionally cornered, a theory that begins to test his own grip on reality as the case progresses without logical resolution. His central role in the story is that of the truth-seeker, willing to entertain abstract and supernatural possibilities that his partner dismisses. Unlike Ikari, who needs concrete evidence, Maniwa accepts that the answer may lie beyond the physical world, a pursuit that comes at great personal cost.
Maniwa's key relationships are defined by contrasts and subconscious connections. His partnership with Ikari is a classic foil dynamic. Ikari is short-tempered and rigid, desiring to close the case with a verifiable culprit, while Maniwa is calm and adaptive, insisting that the phenomenon is ongoing even after a suspect is arrested. His most significant relationship, however, is with an unnamed elderly patient who spends his days writing complex mathematical equations. Although they rarely speak directly, the old man becomes a subconscious guide for Maniwa, entering his dreams and hallucinations. The detective has a strange, intuitive link to this figure, and eventually takes on his role as a sort of guardian who can perceive the true nature of the illusion.
The development of Maniwa is a harrowing descent from a healthy, stable detective into obsessive madness. As the case defies logical explanation, Maniwa begins experiencing auditory and visual hallucinations, including splitting the old man into two figures and hearing warnings on a 51 MHz radio frequency. His obsession leads to his dismissal from the police force, after which he becomes gaunt, stops eating, and spends his days hunting Lil Slugger with makeshift weapons like an umbrella he imagines is a sword. This psychosis, however, paradoxically sharpens his focus. By losing his connection to conventional reality, Maniwa gains the clarity needed to see the mechanics of the shared delusion. He discovers the truth about Tsukiko Sagi's past and finds the original golden bat used to kill her dog, arming himself with the literal weapon needed to confront the monster. In the final episodes, having taken on the mantle of the mysterious old man, Maniwa evolves into a figure known as Radar Man, a wandering knight who battles Lil Slugger directly in a desperate attempt to end the phenomenon for good.
His notable abilities are less about physical prowess and more about perception and deduction. Maniwa is highly intelligent and possesses a sharp analytical mind, allowing him to connect disparate clues that others miss, such as the link between the victims' emotional states. His greatest strength, however, is his willingness to sacrifice his own sanity to understand the truth; to fight an illusion, he learns to see the illusion. This transformation grants him a form of strategic clarity, culminating in his discovery of the physical bat used in the original crime, which becomes the key to his final confrontation.
