** The drawing style of the entire series is a ShoutOut to the Creator/DarioArgento film Film/DeepRed. More specifically, the [[spoiler:wall drawing that Carlo drew of his deranged mother stabbing his father after the latter tried to take her to the clinic for her mental instability]]. In addition, Episode 5 opens with a NightmareFuelColoringBook while the same lullaby (School At Night Lullaby) plays.

** The drawing style of the entire series is a ShoutOut to the Creator/DarioArgento film Film/DeepRed or more specifically the [[spoiler:wall drawing that Carlo drew of his deranged mother stabbing his father after the latter tried to take her to the clinic for her mental instability while lullaby music was playing on a record player,which the killer also needs to listen to in order for her to be able to kill someone by putting herself in the same state of mind as when she killed her husband]]. In addition, Episode 5 opens with a NightmareFuelColoringBook while the same lullaby (School At Night Lullaby) plays.

** [[spoiler:Reisen II]] implies that this is also the motivation behind the {{Hate Plague}}-like events up to now.

* ShoutOut: In part 5, Chen says she fished a two-kilo whitefish and intends to use it for dinner, referencing the "Kahen kilon siika!" meme from a Finnish Touhou fancomics.

** A possibly subtle one: in part 8 Yukari says that her heart is "Far, far in the past", which might be a reference to the fan theory that Yukari is a much older Maribel Hearn that was TrappedInThePast.

* RedHerring: Played with: [[spoiler:Everything points toward Koishi being the cause of everyone turning mad in Gensokyo due to her ability to manipulate the subconscious mind, prompting Yukari to hunt her down and kill her. Turns out not only she's not the cause of the mass insanity, but she was deliberately set up as this trope to make Yukari fall into an ambush set by Reisen II and kill her]].

* [[spoiler:OminousFloatingSpaceship]]: [[spoiler:The Lunarian's Vijoka. A huge, Buddha shaped spaceships.]]

* BackFromTheDead: Koishi in Part 9. [[spoiler:Comes back at first as some kind of spider-like tentacle creature, when then proceeds to assimilate part of Yukari's corpse, including her ''head''.]]

''Koishi Komeiji's Heart-Throbbing Adventure'' (or "Komeiji Koishi No Dokidoki Daibouken" in Japanese) is a WebOriginal series of videos made by Website/NicoNicoDouga user Sentakusen, telling a [[ArsonMurderAndJaywalking harrowing, violent and badly-drawn]] story about [[VideoGame/{{Touhou}} Koishi Komeiji]] attempting to acquire a fishing rod. Set in Gensokyo (albeit with the 'crazy' throttle stuck on full), it's notable for portraying a number of VideoGame/{{Touhou}} characters as substantially more [[AxCrazy mentally unhinged]] than they are in {{canon}}. As far as VideoGame/{{Touhou}} fan-fiction goes, it's at the very extreme end of DarkerAndEdgier as well as BloodierAndGorier reinterpretations of Gensokyo. It is well-known in Japanese Touhou fandom for its CrapsaccharineWorld depiction of Gensokyou where everyone is DrivenToMadness.

** [[spoiler:Koakuma]] is completely beneath anyone's suspicion in the SDM (save Flan), and Satori accusing her of dark planning gets her blasted out of the mansion by Remi [[spoiler:and Patchy].

* [[spoiler:Koakuma is completely beneath anyone's suspicion in the SDM (save Flan), and Satori accusing her of dark planning gets her blasted out of the mansion by Remi and Patchy.]]
* [[spoiler:Lunarians, particularly Yorihime and Toyohime]] who are more or less worshipped by human from Outside World as heroes and role models instead of [[spoiler:masterminds of genocide]].

* DevilInPlainSight[=/=]VillainWithGoodPublicity: [[spoiler:Koakuma is completely beneath anyone's suspicion in the SDM (save Flan), and Satori accusing her of dark planning gets her blasted out of the mansion by Remi and Patchy.]]

* HateSink: [[spoiler:Watatsuki no Toyohime.]] Even the most hardcore fans of this individual (which is a minor part of the fandom) can barely tolerate this person's despicable plottings and actions in the story. Not to mention she crossed MoralEventHorizon by assaulting [[spoiler:Daiyousei]] of all people in Gensokyo.

-->''"And to think all of this shit was caused by a fucking FISHING ROD"''

** Part 6 [[[[Anime/YumeNoCrayonOukoku opening song]]. You will never guess that such cute cheerful song would be used for a video series as demented as this.

* {{Foreshadowing}}: The opening of Episode 5 shows all the characters with severed heads, but Patchouli is the only one who has a normal appearance and she has her head. This foreshadows about [[spoiler:how Koakuma sees everyone, caring little about everyone but Patchouli]].

* WhamEpisode: Parts 8 and 9: most of Gensyoko descent into complete madness, Mokou continue her rampage against the Human Village and horribly wounds Keine, Byakuren gather a large fleet and Youkai army to wipe out all of the remaining humans, [[spoiler:Koakuma]] reveals to have been EvilAllAlong, [[spoiler:Satori]] murders [[spoiler:Orin]], [[spoiler:Yukari]] is killed by [[spoiler:Reisen II]] and Koishi turns out [[spoiler:not being dead and assimilates Yukari's remains, regaining a functional body and possibly part of Yukari's powers]], and is free to continue to wreck havoc. Part 8 even has a disclaimer that it's [[YouHaveBeenWarned the most violent and horrible episode to date]]!

* BackFromTheDead: Koishi in Part 9. [[spoiler: Comes back at first as some kind of spider-like tentacle creature, when then proceeds to assimilate part of Yukari's corpse, including her ''head''.]]

* BigBad: [[spoiler: Koakuma]] is revealed to be the reason why everyone in Gensokyo is going bat-shit crazy. [[spoiler: Except not exactly.]]
** BigBadDuumvirate: It appears that [[spoiler: Koakuma and Reisen II]] are this. [[spoiler: Reisen II is acting on behalf of the Watatsuki sisters, the actual Duumvirate to Koakuma.]]

** [[spoiler: Satori decapitates Rin with her ''bare hands''...while being carried to safety.]]
** [[spoiler:Reisen II]] kills [[spoiler:Yukari]] by detonating a bomb implanted inside [[spoiler: Ran's stomach]], then emptying her rifle ammo on her, ''then'' by [[ThereIsNoKillLikeOverkill detonating]] ''[[ThereIsNoKillLikeOverkill another]]'' [[ThereIsNoKillLikeOverkill bomb]] implanted inside [[spoiler:Chen's stomach]].
* BitchInSheepsClothing: [[spoiler: Koakuma poses as Patchouli's shy and meek assistant. In reality, she's a homicidal psychopath who doesn't give a shit about anyone but herself and Patchouli, manipulating everyone—including Patchouli—in order to bring her plan into fruition.]]

** The induced madness aside, Flan gets this in spades. Torn apart by Koishi, felt even more abandoned than before by Remilia, and then given "BreakThemByTalking" lectures by [[spoiler: Koakuma]] to further break her spirit...[[HumiliationConga along with a rainstorm INDOORS to weaken her further.]]

** [[spoiler: Kaiju! Reimu and Marisa against Yorihime.]] It ends with them dead.

** Reisen vs. [[spoiler:Reisen II]]. [[spoiler: Sedation tends to do that.]]

* DevilInPlainSight[=/=]VillainWithGoodPublicity: [[spoiler: Koakuma is completely beneath anyone's suspicion in the SDM (save Flan), and Satori accusing her of dark planning gets her blasted out of the mansion by Remi and Patchy.]]

** Also, [[spoiler: the Kaiju versions of Suika, Flandre, Marisa and Reimu.]]

* EmptyShell: [[spoiler: Patchouli, after the Hakurei Barrier is destroyed and is abducted by Koakuma. She feels regret upon realizing her blind trust on Koakuma doomed Gensokyo.]]
* ExactWords: The Moonlight Descent plan. [[spoiler: The Lunarians needed the Human Instrumentality Project to purify the Earth, so the Moon could be reunited with the Earth, having been StarCrossedLovers separated in the past, due to Earth becoming tainted.]]

* AGodAmI: [[spoiler: Koakuma.]]
* IHaveYouNowMyPretty: [[spoiler: Koakuma abducts Patchouli before the Hakurei Barrier and Gensokyo are destroyed.]]

** Also, Flandre Scarlet, courtesy of Koishi's...eye...tentacle...thing.

* NotTooDeadToSaveTheDay: After apparently being killed off by Tewi (Having her legs smashed apart by a mochi mallet), Reisen comes out of nowhere, completely intact, and saves Reimu's head from being blown by [[spoiler:Reisen II's moon]] rifle by using [[spoiler: InstantSedation on Reisen II]]. No explanation thus far has been given for this. See [[BackFromTheDead Back from the Grievously Injured]] above.

* OhCrap: A Villainous example, [[spoiler: Hina has this moment when she notices one of Alice's explosive dolls just next to her about to explode]].

** Also, [[spoiler: Kaiju! Reimu uses a gap to perform a suicidal attack on Yorihime. It works.]]
* PowerCopying: Koakuma's power is apparently the ability to steal powers from the dead, implied by her use of a 'miracle' after Sanae's death. [[spoiler: Confirmed after using Sunny's, Luna's, Mystia's, Youmu's, Cirno's and Iku's own powers to fight Reimu.]]

* SharingABody: [[spoiler: Koishi and Yukari with Koishi being the dominant personality.]]

** Episode 9's [[spoiler: head assimilation]] scene [[spoiler:with Koishi's body fusing with Yukari's head]] is a possible reference to ''Manga/JoJosBizarreAdventure'' at the end of Part 1: Phantom Blood where Dio [[spoiler:attempts to assimilate Jonathan Joestar's body as his own]]. And just like Dio, [[spoiler: it is successful.]]

* StarCrossedLovers: As it turns out, [[spoiler: The Moon itself. She used to have a humanoid form and fell in love with another humanoid. However, when they were about to consume their relationship, her mate became tainted and became what we know now as the Earth. Part of the Lunarian's motivation is to remove the Earth's impurities (which is why the Lunarians needed to make world peace on Earth) so he could be reunited with the Moon again.]]

** Reisen implies to be one [[spoiler: when she incapacitate Reisen II]].

** [[spoiler: Apparently, this was needed to purify the Earth, all so him could be reunited with the Moon, who was his lover before he became tainted by the satori creatures.]]

* {{Badass}}: Cirno. Her fight against Star Sapphire is proof enough of that.

* OffscreenMomentofAwesome: Yuuka curb-stomping Medicine Melancholy. [[spoiler:Turns out it was one of those "Yuuka is misunderstood" moments.]]

You can begin watching the series (if you dare...) in English [[http://www.youtube.com/playlist?list=PLP0jCPw9IPWi-Tjr88g5HUvQuqY1asTP4 here]][[note]]The subs are on youtube annotations so they won't work on mobile devices[[/note]].

* AGodAmI: [[spoiler: Koakuma.]]

* [[BackFromTheDead Back From The Grievously Injured]]: Reisen in Part 10, rescuing Reimu from [[spoiler:Reisen II]].

* BewareTheNiceOnes: Aside from those already driven crazy, [[{{Karakasa}} Kogasa]] goes from cute, assuming youkai, to saving herself from Sanae's ColdBloodedTorture via umbrella impalement, all while crucified. It's clearly desperate self-defense rather than UnstoppableRage, but the way she gives her trademark tongue expression and chants 'Urameshiya' beforehand is....
** [[FridgeBrilliance But Kogasa's job is scaring people,]] so it isn't a [[IncrediblyLamePun surprise]] if she does her trademark thing.

** The induced madness aside, Flan gets this in spades. Torn apart by Koishi, felt even more abandoned than before by Remilia, and then given {{Breaking Speech}}ed by [[spoiler: Koakuma]] to further break her spirit...[[HumiliationConga along with a rainstorm INDOORS to weaken her further.]]
* CloudCuckooLander: Koishi. In a very disturbing kind of way.

* EmptyShell: [[spoiler: Patchouli, after the Hakurei Barrier is destroyed and is abducted by Koakuma. She feels regret upon realizing her blind trust on Koakuma doomed Gensokyo. ]]

* {{Foreshadowing}}: The opening of Episode 5 shows all the characters with severed heads, but Patchouli is the only one who has a normal appearance and she has her head. This foreshadows about [[spoiler:how Koakuma sees everyone, caring little about everyone but Patchouli.]]

* GenreShift: The first episodes were abou Koishi being way more insane than usual and being very violent towards, or outright trying to kill, other Touhou characters. The series then shifts into MindScrew territory when it becomes apparent that there are several master minds plotting against each other and Koishi is simply in the middle of all of it... and then the story shifts '''again''' by [[spoiler:having Gensokyo fall to a HatePlague, which drives everyone to insanity, the Hakurei Border gets destroyed by Flandre and now humanity has to deal with almost 30,000 Touhou {{Kaiju}} monsters.]]

* [[ImAHumanitarian I'm A Ghostitarian]]: Yuyuko, whose {{Big Eater}} tendencies are taken {{Up To Eleven}} by ''eating Youmu alive''.

* LateArrivalSpoiler: There has been many fanarts depicting the most important twists of the story including Koakuma [[spoiler:turning out to be evil,]] Koishi's [[spoiler:supposed death and her double resurrection-fusion with Yukari who also supposedly died,]] and Reisen's [[spoiler:seemingly DeadexMachina]]. Lately also started to appear fanarts depicting [[spoiler:the Watatsuki sisters alongside Koakuma and Reisen II]], revealing their heavy involvement in the events of the story.

* NotTooDeadToSaveTheDay: After apparently being killed off by Tewi (Having her legs smashed apart by a mochi mallet), Reisen comes out of nowhere, completely intact, and saves Reimu's head from being blown by [[spoiler:Reisen II's moon]] rifle by using [[spoiler: InstantSedation on Reisen II]]. No explanation thus far has been given for this. See [[BackFromTheDead Back From The Greviously Injured]] above.

* [[OffWithHisHead Off With Her Head]]: Shou and Nazrin's fate for betraying Byakuren, with their headless bodies tied into a pole.

** The drawing style of the entire series is a ShoutOut to the Creator/DarioArgento film Film/DeepRed or more specifically the [[spoiler:wall drawing that Carlo drew of his deranged mother stabbing his father after the latter tried to take her to the clinic for her mental instability while lullaby music was playing on a record player,which the killer also needs to listen to in order for her to be able to kill someone by putting herself in the same state of mind as when she killed her husband.]] In addition, Episode 5 opens with a NightmareFuelColoringBook while the same lullaby (School At Night Lullaby) plays.

* UnwittingPawn: Strangely enough, the deeper the series goes, the more it seems Koishi herself is one of these. [[spoiler:Turns out that she was an unwitting decoy used by the Watatsuki sisters to attract Yukari and have her assassinated in an ambush]].

** Also, [[the Kaiju versions of Suika, Flandre, Marisa and Reimu.]]
