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.[note 1]

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 was young, Ranpo wears a gakuran with a matching student cap and coat, with an old-fashioned flat satchel hung around his waist. When he chooses to activate his "ability", he will put on black glasses which were given to him by Yukichi Fukuzawa.[2]

After the agency's founding, Ranpo wears simple white long sleeves with checkered tie and a pair of dark trousers.[6]

After the cannibalism, Ranpo wears a white long-sleeved shirt and a sleeveless vest suit together with a black ribbon tie.[7]

After defying Fukuzawa's orders during the virus ordeal, Ranpo is told to help a sales staff at one of their client's shopping mall, hence him putting a teddy bear costume.[8]

During the Agency's frameup, Ranpo borrows a cloak from man and his boater hat as a distraction to get away from the military police.[9] Ranpo also wears a disguise in order to get Doppo Kunikida and Fukuzawa out from detainment, consisting of black overalls and a gas mask.[10] In rescuing Akiko Yosano from her execution, Ranpo wears the same outfit, albeit without the gas mask.[9]Because of the Agency's faith in him, Ranpo equally places his trust in them.[14][15] He recognizes how the Agency members, whom he regards as his friends, see him as invincible, so Ranpo has a sense of conviction to protect them and vowed never to let anyone hurt them.[1] This rings true most especially after the events of Cannibalism: Ranpo admits his failure to catch Fyodor Dostoevsky, which might have prevented a child's death and consequently Kunikida's arrest.[8] During such cases, Ranpo does acknowledge that he has limitations himself, but he is nonetheless more than willing to perform any plausible means to solve the situation.

Notably, 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 initially refused to openly admit this to anyone in the Agency, as he refused to believe Fukuzawa when the latter straightforwardly told Ranpo that he is not actually an ability user[2] and seemed to dance around the topic with Yosano,[3] yet he outright admitted his lack of ability after the Yokohama fog incident caused by Tatsuhiko Shibusawa[16] and later to Mushitarō Oguri.

Ranpo urges Mushitaro to surrender (manga) Admitting that he took in Fyodor's methods in himself, Ranpo vows never to let anyone hurt the Agency.

With his vision and desire not to lose to Fyodor nor to anyone again, Ranpo carefully learned Fyodor's ways and willingly took in the Conjurer himself, illustrating Ranpo's exceptional resolve to do anything that he can for the sake of protecting the Agency. He claimed that such intimidation surpasses that of a typical deduction skill, which can defeat even detective killers and evidence suppressors—the great detective's weaknesses—like Mushitarō.[1] He even put up a contingency plan to ensure that the Agency would be given all the help they need, especially from Mushitarō, in their battle against the Decay of the Angel, as he threatened to expose Mushitarō's friend's legacy to the public that might defame the late author.[17]

Poe approaches Ranpo for help regarding a murder case Ranpo offers his help to Poe, who was once his rival.

In addition, Ranpo has a certain kind of charisma that plants an apparent change in his former adversaries into people who aid him subsequently in different manners. One notable example is Edgar Allan Poe, once his sworn rival whom Ranpo defeated in a deduction battle six years ago,[3] who gradually becomes one of Ranpo's trusted allies in his later pursuits and cases, such as the Cannibalism strategy,[18] its aftermath,[8][19][1] and in rescuing Agency members and affiliates during their frameup.[10][9] Another is Mushitarō himself, who prides himself as the infallible detective killer who challenged Ranpo but later warned the great detective of the Decay of the Angel' threat out of his own volition.[20]

Ranpo asks the police to think (manga) Ranpo convinces the police to rethink their perception on the wanted Agency.

Minoura, a police officer who initially doubted Ranpo's detective skills, eventually sought his occasional help[21] and later broke him out from arrest[22] together with 30% of Yokohama's police force.[23] Through his words of persuasion, Ranpo was able to turn such percentage of the military police into believers in the Agency despite being a wanted terrorist at the time.[9]

Ranpo also appears to have a great memory, as he is able to remember his duel with Poe from six years ago and identify Minoura as the "man whose subordinate he arrested".[21] In his 12 years of solving baffling cases as a detective, he seems to remember some of his clients, as hinted when he turned to a specific police officer out of the many arresting him, whom he possibly recognized to have helped out some time in the past.[9]His uncanny aptitude, self-named "Super Deduction" (超ちょう推すい理り, Chō Suiri?), 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. Though he is not unaware of this fact, he initially denies it and continues to believe that he is an ability user. However, after some time, Ranpo has come to accept that he is a non-ability user, albeit occasionally still putting on his glasses to "activate" his ability and perform deductions.
