    Jinpei Matsuda
Voiced by Nobutoshi Canna (JP)

The character that drives the backstory of the 12 Million Hostages story arc. Former member of the bomb squad, he was later transferred to the criminal team because of his That One Case— and it was him who became another painful That One Case for Sato.

    Hiroki Sawada
Voiced by Ai Orikasa (JP) / Maxey Whitehead (EN)

From the Non-Serial Movie Phantom of Baker Street. He is Noah's Ark.
  • Adorably Precocious Child: Subverted, if not deconstructed. While he is young (10) and bears as much adult responsibility (being a master programmer) as for the norm of this trope, he is portrayed as an angsty character. That does not prevent some fans from portraying him per the norm of this trope, though.
  • Author Avatar: Often suspected to be one towards the movie's writer Hisashi Nozawa, not helped by the fact Nozawa himself committed suicide about 1.5 years after the movie screened.
  • Barefoot Suicide: His death is implied this way.
  • Bishounen: At 10, he's a kid edition, but he does have the looks for it.
  • Brain Uploading: He pretty much coded his entire brain as Noah's Ark before his suicide. In the entire movie nobody even questioned whether Noah's Ark is Hiroki.
  • Child Prodigy: Deconstructed. This poor kid's life sucked because he was one.
  • Deus Angst Machina: Consider all tropes surrounding him, and consider his age. Everyone would have reached their Despair Event Horizon.
  • He Knows Too Much: What is being said is the immediate reason for his death is because he found out Schneider was the direct descendant of Jack the Ripper.
  • Heroic Sacrifice: his self-destruction at the end of this movie was that an AI of that complexity is too early for this world and would easily be controled by the bad guys.
  • Ill Boy: While this has not been further expounded about, it certainly does not help with his social issues. But it's not what takes his life.
  • Improbable Age: Remember, he's studying grad school in MIT and written two marketable, major pieces of software at 10 years old, it's pretty exaggerated. Of course, this is also a deconstruction, as he has huge emotional problems because of it.
  • Intelligence Equals Isolation: A pretty tear jerking example as this was not because of his failure to connect with others. In the beginning, Japanese schools just ignored his intelligence. Under the wing of Schneider, he got accelerated at an improbable rate—and in effect became house arrested by Schneider.
  • I Just Want to Have Friends: He almost has no friends.
  • Innocent Prodigy: He switches between this and Wise Beyond Their Years.
  • Lonely Rich Kid: While under foster care by Schneider, although the reason is a bit different from the the standard of that trope—Schneider put him in a highly accelerated educational program and then pretty much put him to work. Understandably, he was a bit broken for that.
  • Parental Abandonment: His parents separated over his education, and he followed his mother to the US. Not long after that, his mother died.
  • Plot-Triggering Death: Were he alive, the entire plot didn't exist at all.
  • One Steve Limit: Averted and then played straight. Hiroki is a very common male name in Japan, and there has been at least two one-timer that has the same name before him. Although, referring to "Hiroki" without any quantification usually refers to him
  • Starts with a Suicide: What begins his case.

    Natsuki Koshimizu
Voiced by Risa Hayamizu (JP)

The "Detective of the South" in the Detectives' Koshien arc. She's from Fukuoka, a big town in the southern island of Kyushu.
  • Amateur Sleuth: One of the more famous High School Student Detectives. She was, but she's no longer a high schooler.
  • Bifauxnen: No wonder the guys, save for Tokitsu, simply assumed that she was a boy too until they saw her in a girly school uniform.
  • Bokukko: Besides her bifauxnen appearance, another reason the guys (sans Tokitsu, who already met her before) mistook her for a guy was her use of male pronouns. Subverted as soon as she's uncovered as Tokitsu's killer, she switches to the more gender-neutral watashi, apparently feeling that she's too bloodstained to use boku anymore as it was a symbol of her youthful innocence.
  • Broken Bird: She was deeply, deeply affected by the death of Kana, and planned to kill the one responsible for it.
  • Fear of Thunder: Subverted, she was faking it.
  • Gender-Blender Name: While "Natsuki" is mostly known as a girl's name, it's actually for both genders.
  • Graceful Loser: Quietly tuned herself in after she was exposed for being the murderer and her plan failed to have all of them starve to death on the island.
  • Has a Type: Apparently, Natsuki likes hot-blooded guys.
  • Headphones Equal Isolation: Invoked. Natsuki wore huge earphones in the beginning, which confused the others and made them think she didn't want to speak too much to them. She actually used them to hide her pierced ears, which would let others know she wasn't a highschooler anymore (Japanese schools are very strict about dress codes and often prohibit the use of any piercings, earrings included). She later hid them with her hair when she couldn't use the 'phones anymore.
  • Older Than They Look: Is already 20 but looks young for her age. She exploits it to try fitting in the group better and not raise any eyebrows.
  • Sailor Fuku: Hers is light blue, with white scarf/collar and black socks. It's also depicted realistically, with a long skirt below the knee.
  • Sympathetic Murderer: Killed fellow Amateur Sleuth Tokitsu, as he insisted that the dead socialite was killed (He had been fooled by a "closed room trick" performed by a thief after the murder, believing it to have been performed by the murderer.) This led to the suicide of the only suspect, Natsuki's friend Kana.
  • Unsettling Gender Reveal: Hakuba, Heiji and Conan didn't know that the very tomboyish Natsuki was a girl, and they only found out when they saw her in a seifuku uniform.
    Heiji: T-that guy's a girl?!
  • Worthy Opponent: Expresses admiration for the boys after her arrest, and wished she could've done a real koshien with them.

    Junya Tokitsu
Voiced by Shinichiro Miki (JP)

The "Detective of the North" in the Detectives' Koshien arc. He's born in Tokyo and raised in Hokkaido, a huge island in northern Japan.

    Dr. Narumi Asai
Voiced by Ai Orikasa (JP)

Appeared in the Moonlight Sonata arc. She is the beautiful doctor of the fishing island of Tsukukage, and kind of a Na´ve Newcomer to the island itself. She is actually Seiji Asou, the son of the late local pianist who died under strange circumstances, and has returned under a disguise to find out who did his family in.

Mandatory Naming Note: His surname by birth, Asou is also that of one of Aoyama's assistants.

    Asami Uchida
Voiced by: Yukari Shin (JPN)

Shinichi, Ran and Sonoko's old sempai, and apparently Shinichi's first love. She invites them to a karaoke party to celebrate her birthday, but then the encounter goes sour as a fire breaks in and Asami, who's taking a nap since she doesn't feel well, almost dies...
  • The Ace: She is very smart, very popular, VERY beautiful... In fact, when she's introduced she has already won both a literary contest and a beauty one, beating at least three sempais of hers to the punch.
  • Always Someone Better: Ran thinks this way about her, though she doesn't hate her one bit.
  • Broken Ace: Never mind her accomplishments, she has a perpetually sad air around her.
  • Cute Sports Club Manager: Of the soccer team in Shinichi, Ran and Sonoko's junior high.
  • Driven to Suicide: Averted. This trope is discussed by Kogoro and the police as one of the possible causes for what happened to her, but it isn't correct.
  • Hello, Nurse!: Was very popular at school.
  • Lethal Chef: Wasn't very good at the kitchen in her junior high and high school days, though she ultimately improved with time. The guys at the club pretended to not notice because they didn't want to hurt her feelings, and the only one who told her so was Shinichi.
  • Love Hurts: She loved Shinichi, but he rejected her love declaration. Her friend and sempai Sawai loved her, but she didn't return his feelings. Then Sawai drugged her and caused a fire to try being her Knight in Shining Armor. Ouch, poor Asami.
  • Sempai Kouhai: She is Ran and Shinichi's senpai.
  • Single Woman Seeks Good Man: Asami came to like Shinichi for his talent and for his blunt approach to things.
  • Student Council President: Of Teitan Highschool, until her graduation.
  • Unrequited Love: For Shinichi. She lampshades it very, very sadly at the end.
    "You can't force someone to open their heart to you."
  • Wounded Gazelle Gambit: Averted. This trope is discussed by Kogoro and the police as one of the possible causes for what happened to her, but it isn't correct.

    Sayuri Matsumoto
Voiced by Maya Okamoto (JP)

Shinichi and Ran's former music teacher, as well as the much-loved daughter of Kiyonaga Matsumoto. Who is poisoned to almost death in her wedding day...

    Yusuke Sakata
Voiced by: Kazuya Ichijou (JP)

A policeman working under Chief Touyama, who appears in the Naniwa Murder Case arc. As well as the Sympathetic Murderer of said arc. Born Yusuke Inaba.
  • Anti-Villain: Not a bad person, but...
  • Driven to Suicide: Tries to shoot himself in the head when found out. Heiji struggles with him and manages to stop him... at the cost of being shot.
  • Love Makes You Evil: The love for his father drove him to kill the ones responsible for the Deadly Prank that murdered him.
  • Knight Templar: Views himself as such. Heiji disagrees.
  • Serial Killer: He killed four people, and was planning to kill two more and use the last one as a scapegoat.
  • Strong Family Resemblance: Looks a lot like his late father. Actually a huge plot point: seeing him caused Numabuchi a Villainous B.S.O.D. that let Yusuke learn what happened to Inaba... and then seeing Inaba's picture lets Conan and Heiji identify him as the real culprit.

    Wataru Date
Voiced by Keiji Fujiwara (JP)

An old friend of Wataru Takagi, and his deceased Big Brother Mentor. Apparently a friend of Tooru Amuro, too.
