''"The masters of puppets are the masters of humans. Ventriloquism is also mind-reading. Not only the voice itself is mimicked, but the voice of the soul as well."''

Sakon is the grandson of the famous Bunraku master, Tachibana Zaemon. He is incredibly shy and lacks confidence in himself. However, when he is with his puppet, Ukon, he is able to focus himself and his crime-solving abilities. As a contrast to traditional Bunraku puppeteering, Sakon is an expert ventriloquist.
Ukon is a beautiful red-haired Bunraku puppet created in 1870, supposedly by the Master puppet-builder Unosuke Koizumi III. But Ukon doesn't act as a good Bunraku puppet should. When he is with Sakon, he is loud-mouthed, obnoxious, flirtatious, coarse, and very egocentric. Together, Sakon and Ukon travel around Japan, solving mysteries, murders, and horrific crimes. In the meantime, Sakon's aunt Kaoruko, a young and pretty police detective, helps him out and keeps an eye on him.

!!''[[{{KarakurizoushiAyatsuriSakon}} Karakurizoushi Ayatsuri Sakon]]'' provides examples of:

* AmateurSleuth - Sakon, who is also a MysteryMagnet.
* AnyoneCanDie - several of the characters seems to be in the story just to become victims.
* ArrangedMarriage - Kaoruko receives a formal proposal (''omiai''), in the Noh Arc.
* AssholeVictim - [[spoiler: Takamura, the TV director in the second arc]].
* {{Bishonen}} - Sakon definitely qualifies. He is even voiced by a [[MegumiOgata woman]].
* ContrivedCoincidence - overused, like a storm that starts just to cause a blackout or to make the roads become blocked.
* {{Curse}} - the main theme of the final arc.
* DarkAndTroubledPast - several characters, [[spoiler: including Sakon and his family.]]
* DoubleConsciousness - Ukon is just a puppet but he have very strong opinions. Sakon, who gives him life, is the opposite type, being sweet, gentle and shy. It's like Sakon uses Ukon to voices the opinions that he is uncapable to. This is specially evident on episode 24, [[spoiler: when Ukon respond "he can't even says what he wants without me around" to a person who questions Ukon's presence in an important meeting.]]
* DrivenToSuicide - [[spoiler: Osamu]], in the first arc.
* EmpathicEnvironment - and how! Almost all examples in this trope happens in the series.
* EvenTheGuysWantHim - Sakon. He melts the girls around him and he seems to be a little bit aware of this fact but he is too shy to do something about. His friend Fujita says that "Although I'm a guy, I think he is hot stuff".
* EvilGloating - the villain of the Noh Arc just [[JustBetweenYouAndMe had to explain the entire plot]].
* GetAHoldOfYourselfMan - [[spoiler:Shiho had to shaken Sakon a little bit in the last episode.]]
* HeyItsThatVoice - [[Creator/MotokoKumai Ukon]] is [[Manga/CardcaptorSakura Syaoran Li]], [[MegumiOgata Sakon]] is [[Anime/NeonGenesisEvangelion Shinji Ikari]]
* HiddenVillain - used in the [[spoiler: Museum Arc and in the Cursed Sword Arc.]]
* IJustWantMyBelovedToBeHappy - poor [[spoiler:Numata and his bad choices. He would never had guessed that [[BackFromTheDead Tsukiko wasn't dead]].]]
* ISeeDeadPeople - Sakon have the ability to talk to the dead - or at least, he makes people believe on this.
* KabukiSounds - and Noh elements, in the Noh Arc.
* OnTheNextEpisodeOfCatchPhrase - ''"People can not live in grief."''
* ReunionRevenge - The series had one of these involving a school's puppetry club. [[spoiler:Subverted in that it's actually the victim's older brother who's the murderer, though it's set up to make the bullies think it's the victim's ghost that's doing it.]]
* TheReveal - always in the end of each arc [[spoiler: with Sakon explaining how and why the culprit committed the crime.]]
* RiddleOfTheSphinx - in one episode, Sakon corrects a man who tells him about the Egyptian riddle of the sphinx.
* UnusuallyUninterestingSight - The main character is a puppeteer who walks around talking to his puppet all hours of the day, and makes it talk back, even arguing with it at times. No character treats him as mentally unbalanced or untrustworthy in any way, to the point where he can question people while trying to solve mysteries, and the people he questions don't say a word about the puppet.
