• Even bumbling detectives in anime can get the job done with their unique personalities and humor.
  • Idiocy is embraced in versatile ways among anime detectives, adding entertainment to dark themes.
  • Some detectives like Grevil may lack skills but use power to solve cases, while others lack experience like Totomaru.

When it comes to detectives in anime, they come in all forms. There are the smart and calculating ones who are focused and organized, and there are detectives who are quite literally the opposite of that. They might not be as smart or quick-witted as detectives should be, but what they lack in intelligence, they make up for in personality, and more often than not, despite their fooling, they end up getting the job done.

Kogoro Mouri is a private detective in Detective Conan who fools around more than he investigates. It’s easy to overlook Kogori when he’s either sleeping, drinking, or acting foolish. He rarely takes cases seriously, except if they affect him or someone he loves. In addition to his laziness, he loves beautiful women and will take any chance he gets to show off and try to impress them.

Money moves Kogoro, meaning he does not settle for cheap jobs. He is quite good at being a detective because he follows protocol, but that’s mostly because of Conan.

He extends leniency to individuals, even when their actions suggest they deserve otherwise.

No doubt Kenji has solved lots of cases, even difficult ones, but one may describe him as a happy fool. When Kenji is investigating and interrogating suspects, he asks outright and believes whatever they tell him. Kenji fails to realize these suspects will lie to get out of trouble. Other than this, Kenji is a good detective, and he looks both calm and innocent, but all of that can change when he has a friend he needs to help.

Bungo Stray Dogs: 8 Reasons Why Ranpo Is The Armed Detective Agency’s Most Vital Member

The Armed Detective Agency has several valuable members, but Ranpo’s importance cannot be underestimated.

However, one must note the times when Ranpo just lets himself not be good and acts like a child. He enjoys teasing the other detectives in the agency, and there are times he does not take up cases because he feels lazy.

Clueless And Unable To Draw Conclusions

Since Grevil is an aristocrat, he uses his power to make the police department install him as a detective. Grevil has an interest in crime, but somewhat lacks the adequate skills and facilities to be a detective. Instead, as a man with power, he uses it to get what he wants.

Grevil knows he is a terrible detective, but he does not leave the police force; instead, he goes to meet his sister, Victorique, for help. Victorique is very observant, and she notices the slightest bit of information, a trait detectives should have. Viewers may find Grevil’s presence on the police force insulting, seeing that he almost wrongfully convicts someone of a crime.

Soon after, Sosuke began assisting Akechi, and upon Akechi’s death, he adopted his name and established the Boy Detectives Club detective agency.

Akechi also heads the Akechi Investigation Firm, but he does not do much as a detective. He lets laziness limit him when he can do so much more, like his father did. Akechi just lets the members of his agency do whatever they like with little to no supervision.

Best Mystery Anime, Ranked

Watching a plot slowly unravel is seriously fun as these fantastic anime mystery stories show.

Totomaru takes action before thinking, and it is a dangerous trait to have as a detective, because he should be able to think first and cover all the basics before making a decision. Another thing is that he is empathic, and sometimes Totomaru gets too attached to a case, even going as far as praying for the victims.

Sherlock Shellingford is a detective and the leader of Milky Holmes, an all-girls detective group. For a detective, Shellingford is quite energetic. Being energetic is not necessarily a bad thing, but her excessive energy often leads her to flee from confrontations.

She is always trying to see the good side of things, ignoring the bad, and getting others to do the same. In addition, Shellingford is extremely clumsy and disorganized. This is not a good trait for a detective, but she does manage to get one thing right: being a good thinker, as she is very intuitive.
