''Master Keaton'' is an anime/manga by Hokusei Katsushika and Creator/NaokiUrasawa. It stars a man named Taichi Hiragi-Keaton, a former [[AdventurerArchaeologist archaeologist]], but now a teacher and insurance fraud investigator. The story follows his adventures as he takes on various cases.

A sequel just started being published, after an almost 20 year hiatus, as ''Master Keaton Remaster''. The first manga series was licensed by VizMedia in March 2014.

!!''Master Keaton'' contains examples of the following tropes:

* AdventurerArchaeologist - Subverted, as when he was an archaeologist, he didn't see much action. It's only after he changed professions to insurance fraud investigator, that he saw any action.
** Technically, Keaton does see some action as an archaeologist -- the story of "A Kahariman in the Desert", for instance, allows him to use his survival training to help a group of fellow archaeologists survive after [[spoiler: they unintentionally [[ChasedByAngryNatives piss off the natives]] and are left to die in the freezing desert of western China]].
* AngryGuardDog - Subverted, in that the dog(a specially trained German Shepherd) actively tries to [[TheChase track Keaton and attempt to kill him.]]
* BadassBystander and BadassNormal - Keaton has a tendency to be this in other people's stories, frequently getting involved in complete strangers' lives just in time to save the day. Most people tend to underestimate him at first glance, and show surprise when his {{Hidden Depths}} are finally revealed.
* {{UsefulNotes/Brits With Battleships}} - Due to his British [=SAS=] background.
* ButNotTooForeign - Taichi Keaton's mother was English, but his father is Japanese. His parents separated early in life, and he lived with his mother in the UK.
* BitterAlmonds - Referenced in the death of an ex-KGB spy, though in this case, it has a peach-like smell instead.
* BrokenPedestal - Keaton is called to investigate two murders in London that seem to be the work of his old fencing instructor.
* BumblingDad - Both Keaton and his father Taihei Hiraga are not exactly stellar examples of fatherhood -- both Keaton and his daughter Yuriko essentially lived with their mothers following their parents' respective divorces.
* CantHoldHisLiquor - Keaton's a lightweight when it comes to alcohol.
* ComfortingTheWidow - A type 2. Charlie, a detective and childhood friend of Keaton's, tries to comfort the widow of a recently deceased millionaire [[spoiler: only to find out that the widow was the killer]].
* CoolOldGuy and CoolOldLady - Keaton runs into several of these throughout the series, including an elderly woman who claims to be on the run from the Czech Secret Service and an elderly man who has some mysterious connection to the Romanovs.
* CoolTeacher: Keaton's {{Mentor}}, Oxford archaeology professor Yuri Scott, inspired him to become a teacher as well. Keaton even Namesake named his daughter Yuriko after his old professor. [[spoiler: When Keaton receives the news that Yuri Scott has died toward the end of the manga, the heartbroken look on his face is a complete TearJerker moment.]]
* DefectorFromCommieLand: Since the series takes place just after the end of the Cold War, more than a few stories deal with former defectors and the effects that the new world order are starting to have on them.
* DesperatelyLookingForAPurposeInLife All other plots aside, this series is really about Keaton's quest to determine what he wants to do with his life.
* {{Expy}} - Keaton and Yuriko look like Kosaku Matsuda and Yawara Inokuma from ''Manga/YawaraAFashionableJudoGirl''. [[MST3KMantra Better not to think that they're a romantic couple, though]].
* {{Flopsy}} - A friend of Keaton's is targeted by some conmen with this scam.
* GoodIsNotDumb
* HeelRealization - Used with the IRA bomb-maker in the below HitmanWithAHeart entry.
* HitmanWithAHeart - Used a few times. In one episode, an IRA bomb-maker has a change of heart, and he and Keaton have to find two bombs in a crowded shopping mall and defuse them before they blow.
* ImplacableMan - A zoomorphic version. One episode features a military-trained dog which is commanded to track Keaton down in the woods and kill him.
* LeftHanging - Because the anime cherry-picked episodes instead of following the manga storyline, the series ends without an actual ending to Keaton's story.
* ManicPixieDreamGirl - Yuriko has elements of this.
* ObfuscatingStupidity - Keaton is a [[IncrediblyLamePun master]] of this too.
* PantheraAwesome - One episode involves a tiger in Japan being pursued by Yakuza. [[spoiler: The Yakuza aren't after the tiger, but guns being smuggled in the tiger's cage]].
* PoorlyDisguisedPilot - The final 2 episodes, "Hunting Season", feels like a pilot for another series, as the focus shifts from Keaton to his former fencing instructor, but seemingly nothing came of this.
** Technically, this is because the anime series takes selected plots from the manga and assembles them in (for the most part) no particular order. The "Hunting Season" storyline is from midway through the manga -- it's not meant to be a finale.
* RedemptionEqualsDeath - [[SubvertedTrope Subverted]] with the [[spoiler:IRA bomb-maker]].
* {{Seinen}}
* ShownTheirWork - Naoki Urasawa is a dedicated Germanophile (as his other series ''{{Anime/Monster}}'' suggests), and the historical accuracies of post-Cold War European politics are very well researched.
* ShorterMeansSmarter - The head of a group of [[BountyHunter bounty hunters]] that Keaton runs into is nick-named "Little Giant"
* WellDoneSonGuy - Keaton occasionally meets this sort of person, but there's a particularly inversion of this trope in a musician who used his father's disdain as his inspiration for writing music. When his father went broke, he found that he was no longer able to write music.
