Ranpo Edogawa

Ranpo Edogawa (江戸川 乱歩,) is a member of the Armed Detective Agency. He is known as one of the best detectives out there, despite not being an ability user.

Appearance
Ranpo is a young man with a fair complexion and short, messy black hair. His eyes, which are closed most of the time, are brown.

His attire consists of a brown inverness cape that he wears over his shoulders and whose color matches both his hat and his pants. Under that, he wears a dark grey blazer and a white button-up with a light and dark blue striped tie. Under his three-quarter length pants, he wears long white socks that cover the visible part of his legs, and simple black shoes.

When he chooses to activate his "ability", he will put on black glasses which were given to him by Yukichi Fukuzawa.

Personality
Ranpo takes extreme pride in his "ability" which can deduct any mystery in mere seconds, with which he has solved countless cases. He is often found bragging about his status as the Greatest Detective.

He is also shown to be rather childish, frequently teasing the other detectives in the agency and sometimes refusing to do work or cases for trivial reasons such as laziness or spite. However, he can become serious and calm when the situation calls for it. He is also incredibly intelligent and is commended for it by the rest of the Armed Detective Agency, even more so because he lacks ability. It's possible that his childish demeanor is a coping mechanism for how he was traumatized by his childhood.

Even though his colleagues seem to think that he is completely oblivious to the fact that he is not an ability user, he is aware that his Super Deduction is in fact not an ability. However, since the agency puts so much faith into him, he refuses to openly admit to anyone in the agency, as he seems to dance around the topic with Akiko Yosano, yet outright admitted his lack of ability to Mushitaro Oguri and did so too in Dead Apple.

Ranpo has been shown to be unable to complete simple tasks such as riding a train or finding his way home when not utilizing his Super Deduction.

Ability
His uncanny aptitude, self-named "Super Deduction (超推理,)", allows him to deduce the "truth" about any crime by giving him every information about it such as where to find evidence and who the culprit is within a matter of seconds. Ranpo "activates" this ability by putting on a pair of glasses given to him by the director.

His ability seems to not only be applicable to crime scenes but to other scenarios as well. When Ranpo decides to activate his "ability," he will be able to find information and clues about a certain situation no matter how small, and with them instantaneously make extremely precise predictions. In fact, so far none of his deductions have been known to be erroneous or inaccurate.

This is shown when he easily solved the murder of Yamagiwa, which was deemed almost impossible by the police due to the severe lack of evidence.

Eventually, it is revealed that he is able to deduce everything simply due to his own extraordinary intelligence and that he does not possess an ability. Ranpo however, if not unaware of this fact, denies it and continues to believe that he is an ability user.

Trivia

 * He along with several other characters made a guest appearance in the mobile game Love Heaven as limited-time characters.
 * He is named after the Japanese author, Edogawa Ranpo, who also played a significant role in developing Japanese mystery fiction. His name is a pun on Edgar Allan Poe, whom he admired. This admiration is inversed in the series.
 * On that same note, Edogawa Ranpo was simply the pseudonym his author counterpart went by. His real name was Hirai Tarō.
 * Ranpo seems unable to sleep if it is pitch black.
 * Ranpo is the only known  Ability user  whose Ability name is not a reference to a work of the author they are named after. This is an early hint to the fact that it is not an Ability at all and he is not an Ability user.
 * Though Ranpo's father is never named in The Untold Origins of the Detective Agency, both his job as a detective and the famous cases he has solved imply that he may have been directly inspired by Akechi Kogoro, the detective who author Edogawa Ranpo often focused his detective fiction around.
 * Ranpo was not born in Yokohama. He was raised in the countryside until the death of his parents when he then moved to Yokohama shortly afterward per his father's suggestion.
