The scene is Steam City, a London-ish city which represents an entire civilization run by coal and steam power. Because of steam, the city is sometimes covered in a mist. Villains take advantage of the steamy mist to hide and execute their evil plans. Only a few dare venture into what's beyond the steamy mist. They are known as the Steam Detectives: Narutaki, his nurse-assistant Lingling, and his Megamaton robot Goriki.

A manga by Kia Asamiya, who created it for his son. It was later adapted into a 26-episode TV anime series produced by {{Xebec}}.

!!This work provides examples of:

* AbnormalAmmo: Often used by Narutaki with his equally-abnormal gun.
* AccidentalHero: Narutaki foils a bank heist (unintentionally) while chasing a lost cat across town. [[LampshadeHanging Even the criminals remark on how pathetic they are.]]
* AccidentalPervert: Narutaki and Machine Baron.
* AmazingFreakingGrace: Kia Asamiya uses [[http://www.youtube.com/watch?v=I_5MUpFQZQ4 this]] in some intervals during the story, usually to great dramatic effects.
* [[AscendedFanboy Ascended Fangirl]]: Ling Ling appears in Steam King's third novel, much to her surprise.
* ATwinkleInTheSky: Machine Baron and Crimson Scorpion are common victims.
* BreakingTheFourthWall: Said word for word by Ling Ling in episode 19.
* CityNoir
* ClassyCatBurglar: Crimson Scorpion
* DagwoodSandwich: Episode 13
* DeadlyDoctor: Lang Lang
* {{Determinator}}: In one scene, Narutaki is barely hanging onto the side of a bridge that was just blown up by Le Bled, who has him a cane-gunpoint. A bomb is set to explode at a nearby hospital in a matter of minutes. When taunted about how he planned to get out of his perilous situation, Narutaki simply says, "[[{{Determinator}} Not Give Up.]]"
* DistressedDamsel: Ling Ling, sometimes.
* {{Expy}}: Le Bled is very reminiscent of [[Anime/MobileSuitGundam Char]], and Night Phantom looks like a villainous Franchise/{{Batman}}.
* EvilCounterpart: Le Bled and Lang Lang to Narutaki and Ling Ling. Their Megamatons too, except Le Bled's can fly.
* FightingFromTheInside: [[spoiler:Steam King]]
* ForScience: Where Dr. Hsu and Dr. Guilty disagreed on about using Megamaton technology.
* GrapplingHookPistol
* HelloNurse: Ling Ling and Lang Lang
* HeroicBSOD: After failing to deliver a vaccine in time to save a sickly girl, Narutaki falls into despair.
* HostageForMacGuffin: Of course.
* HumongousMecha: The Megamatons are minor examples, quite often used as {{Robot Buddy}}s.
* IKnowYouAreInThereSomewhereFight: Ling Ling to [[spoiler:Steam King]]
* IncurableCoughOfDeath: Le Bled's reason for doing what he does; he wants to live his life to the fullest before he dies.
* InspectorJavert: Onigawara displays this trait in an episode where Goriki (and Narutaki, by extension) are framed.
* TheJeeves: Kawakubo
* JekyllAndHyde: [[spoiler:Steam King and King Steam/Emperor of Steam]]
* KidAnova
* KidDetective

* LimitedWardrobe: Ling Ling, who wears her nurse outfit almost nonstop. [[{{Fanservice}} Except when going swimming or in the bathtub, of course.]]
* MacGuffin: Several times.
* MarilynManeuver: Leads to an EurekaMoment, followed by AccidentalInnuendo.
* {{Meitantei}}
* MineralMacGuffin: A rare meteornite (from a meteorite; NOT a misspelling) which would be cleaner than coal and power Steam City for 200,000 years.
* MundaneUtility: Goriki possesses a tong attachment, used for delicately picking up pastries. When he accidentally crushes it, causing the cream to spill out, he then adopts a PoseOfSupplication.
* NamesToKnowInAnime
** Creator/AkioOhtsuka is the Night Phantom.
** Creator/NorioWakamoto is the Machine Baron.
** Creator/SoichiroHoshi is Narutaki.
** Creator/YuiHorie is Gina
* NoCelebritiesWereHarmed: [[Creator/StephenKing Steam King]]
* OutOfGenreExperience: After getting slapped by Ling Ling for seemingly inexplicable reasons (at least to Narutaki), Narutaki angrily hurls his cup of coffee against the wall, only for it to bounce around like a superball instead of shattering on impact. He then opens a window to let it out, only to have it [[spoiler: circle the ''ENTIRE EARTH'', come back, ''RING THE DOORBELL'', and force itself down his throat,]] which he then coughs up. Even for a slapstick moment, this is way out of left field. Ling Ling has a similar moment with a hairbrush, [[GenreSavvy which ceases its rebounding upon coming bristle-to-face with an angry Ling Ling,]] [[EverythingTalks even ''APOLOGIZING VOCALLY'' for "causing trouble".]]
** Actually, scratch that. The entirety of episode 13 qualifies.
* PhantomThief: Le Bled, anyone?
* ReasonableAuthorityFigure: Chief Inspector Yagami
* RecapEpisode: Episode 18
* RedemptionEqualsDeath: [[spoiler:Steam King]]
* RocketPunch: Several Megamatons, including Goriki and Shadowbolt.
* RodentsOfUnusualSize: Teng Shing, a gigantic hamster.
* SamusIsAGirl: [[spoiler:"Justice" is actually Anna.]] Absolutely not related to that [[spoiler:[[VideoGame/GuiltyGear other Justice]]]], although the trope still applies.
* ShoutOut: One of Crimson Scorpion's targets is ''SilentMoebius'', said to be one of the world's greatest jewels.
** In episode 11, Ling-Ling re-creates the iconic flying skirt scene from TheSevenYearItch.
*** In episode 19, Le Bled quotes a line from Vera Lynn's We'll Meet Again as he flees the scene.
* ScoobyDooHoax: Crimson Scorpion is fond of them. Narutaki ain't fooled.
* SiblingYinYang: Ling Ling and Lang Lang, complete with contrasting colors.
* SplitPersonality: [[spoiler:Steam King]]
* SteamPunk
* TheStinger: After every preview for the next episode, a still frame of a completely random scene from the episode (totally regardless of its importance in the plot) appears for a few second, with some cheesy music.
* StockFootage: Whenever Goriki is called upon and sent through the underground pass.
* ThoseTwoGuys: Pasta and Doria, Crimson Scorpion's henchmen (among others at least, but only these two are consistently featured). Even though they are Bad Guys, they do NOT qualify as being ThoseTwoBadGuys.
* TeamPet: Teng Shing for the main cast.
* ThisIsADrill: Goriki's standard FinishingMove. Also used by Narutaki as one of his gun's special attachments.
* VictoryPose: All the time. In particular is when Goriki (finally) places a pastry on his tray without it getting squashed. He is then summarily charged hundreds of times for the one pastry he succeeded in getting, as well as all the failures. Cue HeroicBSOD.
