Koishi Komeiji's Heart-Throbbing Adventure
"My hat is my friend. It helps me relax <3"
"And to think all of this shit was caused by a fucking FISHING ROD"
—A Youtube Commenter
is a Web Original
series of videos made by Nico Nico Douga
user Sentakusen, telling a harrowing, violent and badly-drawn
story about 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 Touhou
characters as substantially more mentally unhinged than they are in canon
. As far as Touhou
fan-fiction goes, it's at the very extreme end of Darker and Edgier
as well as Bloodier and Gorier
reinterpretations of Gensokyo. It is well-known in Japanese Touhou fandom for its Crap Saccharine World
depiction of Gensokyou where everyone is Driven to Madness

You can begin watching the series (if you dare...) in English 
This show provides examples of
- A God Am I: Koakuma.
- Alien Invasion: Well, a Youkai Invasion lead by Byakuren, but with the prerequisite UFOs.
- In the finale, Watatsuki no Toyohime informs the world that the peace will be broken by an alien invasion. The aliens in question being the residents of Gensokyo, transformed into savage monsters by the effects of the moon.
- Appendage Assimilation: Koishi to Yukari...almost wholesale.
- Art Evolution: The drawing improves with each episode, going from the very rough style of the first episodes, to a much more smoother style by the time of episode 7. Episodes 11, 12 and the first part of 13 are in Deliberately Monochrome, with the occasional Splash of Color.
- Attempted Rape: To Sanae in Part 7.
- Back from the Dead: Koishi in Part 9. 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.
- Back From The Grievously Injured: Reisen in Part 10, rescuing Reimu from Reisen II.
- Somewhat subverted in Part 19 [2/9], as we saw Tewi holding a straw doll with broken legs and a mochi mallet, implying that what we saw in part 8 is Tewi smashing that doll's legs, while the actual Reisen is somewhere out there, on her way to save Reimu or something. See Not Too Dead to Save the Day below for more explanation.
- Badass: Cirno. Her fight against Star Sapphire is proof enough of that.
- Bad Boss: The Watatsuki sisters toward Satori.
- Beware the Nice Ones: Aside from those already driven crazy, Kogasa goes from cute, assuming youkai, to saving herself from Sanae's Cold-Blooded Torture via umbrella impalement, all while crucified. It's clearly desperate self-defense rather than Unstoppable Rage, but the way she gives her trademark tongue expression and chants 'Urameshiya' beforehand is....
- Big Bad: Koakuma is revealed to be the reason why everyone in Gensokyo is going bat-shit crazy. Except not exactly.
- Big Bad Duumvirate: It appears that Koakuma and Reisen II are this. Reisen II is acting on behalf of the Watatsuki sisters, the actual Duumvirate to Koakuma.
- Big Bad Ensemble: The series hints at someone from the moon behind Reisen II's involvement, later revealed to be the Watatsuki sisters who are also the masterminds behind the whole plot, and we still don't know if Byakuren's invasion is from induced madness or not.
- Big Damn Heroes: Marisa and Alice show up in the nick of time to prevent Nitori from being burned at the stake by a turned crazy Hina.
- Reisen coming out of nowhere to render Reisen II unconscious before the latter can shoot Reimu.
- Kanako also performed this awesomely for Sanae to prevent an imminent rape by her bullies.
- In episode 12, Marisa and Alice again saving the Human Village from Mokou's rampage, then later Mamizou saving in extremis Alice from Nue while Miko and her group saves Marisa from Byakuren's fleet.
- Bloodier and Gorier:
- To put this in perspective, the first real fight in the series is when Meiling prevents Koishi from entering the Scarlet Devil Mansion. She gets the entire front of her neck torn out so that the spine is visible.
- Sanae captures and tortures Kogasa, before getting killed herself by impalement via the latter's umbrella.
- Mokou destroys the human village, and kills everyone in it.
- Star Sapphire literally pulps the other two fairies with a chainsaw.
- Tewi breaks Reisen's legs with a mochi-pounding mallet.
- Satori decapitates Rin with her bare hands...while being carried to safety.
- Reisen II kills Yukari by detonating a bomb implanted inside Ran's stomach, then emptying her rifle ammo on her, then by detonating another bomb implanted inside Chen's stomach.
- Bitch in Sheep's Clothing: 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.
- Blue and Orange Morality: Calling Koishi outright evil is a stretch, but she's definitely not playing by anyone else's sense of morality. She apparently gets better after assimilating Yukari's head.
- Break the Cutie:
- Cloud Cuckoo Lander: Koishi. In a very disturbing kind of way.
- Combat Tentacles: Koishi and Satori has them to great effect.
- Crapsaccharine World: The introductions up until Part 7 or so hammer this home hard. The early ones recap the previous part with crayon drawings, implied to be by Koishi herself.
- Curb-Stomp Battle:
- Koishi(EX-boss) versus Meiling(3rd Stage Boss). Meiling survives, though.
- Another example would be Part 8, where Koishi fights Yukari Yakumo. It doesn't end well for Koishi. At first...
- Medicine Melancholy vs. Yuuka Kazami, we only see the aftermath of the fight, with a limbless Medicine desperately trying to crawl away. Turns out Yuuka is trying to save Medicine from something else that took her limbs. Whatever it is, 10 episodes later and Yuuka's still fighting it.
- Reisen vs. Reisen II. Sedation tends to do that.
- Cute and Psycho: EVERYONE... Well, not everyone, but definitely the vast majority.
- Darker and Edgier: Ah-yup.
- Dark Messiah: Byakuren, in spades.
- Death Equals Redemption: Sanae remembers in her dying moments why she came to Gensokyo in the first place and realizes what kind of monster she had become.
- Devil in Plain Sight/Villain with Good Publicity: 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.
- Driven to Madness: The driving plot of the whole thing: SOMEONE is trying to drive all of Gensokyo crazy...and doing a damn fine job too. It's revealed to be the doing of the Watatsuki sisters, with the help of Koakuma and Satori. (albeit begrudgingly for the latter)
- Dying as Yourself: Sanae.
- Dysfunction Junction: The Scarlet Devil Mansion seems to be one.
- Femme Fatalons: Koishi has hands with very long, claw-like fingers. Their exact length tends to change, though.
- Fingore: When Koishi gets locked up in a room, she tries to literally claw at the door until all her nails are BARELY attached to her fingers. Then when the story comes back to her again, we find that all her nails have fallen off. Squicky indeed.
- Freudian Excuse: Episode 7 is one long one of these for Sanae.
- 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 how Koakuma sees everyone, caring little about everyone but Patchouli.
- Gambit Pileup: The plot is starting to look a little something like this. The three players so far are the Watatsuki sisters, the masterminds behind everything, Satori who's forced to work for the sisters and desperately tries to double-cross them, and the remaining sane people of Gensokyo trying to understand what the hell is happening and stop it. There's also Lord Tsukuyomi and the rest of the moon whose goal is a Human Instrumentality Project, something the Watatsuki sisters are secretly opposing with the Moonlight Descent plan.
- I Have You Now, My Pretty: After the Watatsuki sisters reveal their true colors and summon the Vi-Joker, Koakuma abducts Patchouli and gets into the Vi-Joker as well.
- I'm A Ghostitarian: Yuyuko, whose Big Eater tendencies are taken Up to Eleven by eating Youmu alive.
- I'm a Humanitarian: The youkai led by the Myouren Temple crew (minus Shou and Nazrin, for some reason)
- Impaled with Extreme Prejudice:
- How Sanae dies. By an umbrella, no less.
- Also, Flandre Scarlet, courtesy of Koishi's...eye...tentacle...thing.
- In-Joke: The "fishing rod" is becoming this with people with knowledge of the series advising others to "carry a fishing rod" just in case.
- Killed Offscreen: Iku Nagae, presumably by Tenshi who put her out of her misery. Koakuma also mentions Sanae killed Mystia during her "youkai extermination".
- Last of Their Kind: Satori and Koishi are the last satoris in existence.
- Late-Arrival Spoiler: There has been many fanarts depicting the most important twists of the story including Koakuma turning out to be evil, Koishi's supposed death and her double resurrection-fusion with Yukari who also supposedly died, and Reisen's seemingly Deadex Machina. Lately also started to appear fanarts depicting the Watatsuki sisters alongside Koakuma and Reisen II, revealing their heavy involvement in the events of the story.
- Mad Love: Koakuma towards Patchouli.
- Made of Iron: Koishi and Satori can withstand absurd amounts of punishment, even by youkai standards, whose constitution is far stronger than humans. Justified in that it wasn't their true body that was damaged.
- Mercy Kill: A tired and emotionally distressed Satori does this to Orin.
- Iku presumably got one from Tenshi.
- Mind Screw: It's not clear which parts of the events depicted between Daiyousei and Cirno the night the mass-insanity began are real or a product of them being affected by the madness plague.
- Mind Screwdriver: The first part of episode 11 explains a lot of the previous events, give us a Team Shot revealing who hasn't gone crazy and are fighting to resolve the incident, and gives concrete hints about the responsible behind the Hate Plague.
- Not Too Dead to Save the Day: 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 Reisen II's moon rifle by using Instant Sedation on Reisen II. No explanation thus far has been given for this. See Back From The Greviously Injured above.
- Perhaps Tewi didn't actually crush the real Reisen's legs?
- Exactly how canon that part was seems to be debatable, because at the same time, Yuuka was seen seriously injuring Medicine. Yuuka later appears in an image along with the heroes, as someone trying to keep the peace. It turns out she was trying to save Medicine from something else.
- Offscreen Momentof Awesome: Yuuka curb-stomping Medicine Melancholy. Turns out it was one of those "Yuuka is misunderstood" moments.
- Marisa and Alice defeating Mokou.
- Oh Crap!: A Villainous example, Hina has this moment when she notices one of Alice's explosive dolls just next to her about to explode.
- Later, Yukari has one just before a Ran that was turned into a human bomb explodes right in front of her.
- Poor Communication Kills: Remilia, toward Flan. Remilia was not there to save Meiling or Flan from Koishi's rampage, because she was at Reimu's discussing Flan's improvement and showing the parasol she had planned to give Flan when she returned to the mansion. As a result, Flan believes Remi only sees her as a burden, which is why she wasn't saved.
Patchouli: You really don't know how to talk to her, do you?
- Portal Cut: Yukari uses her gaps to cut off all of Koishi's limbs simultaneously. And then gives her the guillotine treatment.
- Power Copying: Koakuma's power is apparently the ability to steal powers from the dead, implied by her use of a 'miracle' after Sanae's death. Confirmed after using Sunny's, Luna's, Mystia's, Youmu's, Cirno's and Iku's own powers to fight Reimu.
- Puppeteer Parasite: Satori and Koishi, apparently a common trait of their species. Their true body is actually their Third Eye. At least they are considerate enough to only take control of hosts that are already dead.
- Red Herring: Played with: 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.
- Roaring Rampage of Revenge: Sanae's bullies react to their humiliation by Kanako's hands by burning her house down, with her parents inside. Sanae keeps the chain going by slaughtering them to the one.
- Reisen II implies that this is also the motivation behind the Hate Plague-like events up to now.
- Say It with Hearts: Koishi does this often.
- Sharing a Body: Koishi and Yukari with Koishi being the dominant personality.
- Shout-Out: 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.
- "I believe in my hat who believes in me!"
- "My name is Koishi Komeiji. You cut my arm off. Prepare to die."
- 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 Trapped in the Past.
- Episode 9's head assimilation scene with Koishi's body fusing with Yukari's head is a possible reference to JoJo's Bizarre Adventure at the end of Part 1: Phantom Blood where Dio attempts to assimilate Jonathan Joestar's body as his own. And just like Dio, it is successful.
- The art style of the entire series is a Shout-Out to the Dario Argento film Deep Red or more specifically the 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 Nightmare Fuel Coloring Book while the same lullaby (School At Night Lullaby) plays.
- Sociopathic Hero: Marisa is a borderline one, not feeling a single shred of emotion at seeing the cadaver of her father. She states that all the time she spent isolated in the Forest of Magic to study magic killed her capacity to feel emotions. What prevents her for being a full sociopath is that she states that there are other people that she did bonded with and come to care for, Reimu and Alice. Worse, even though she makes a grave for her father, she states that it was only because she read a book where the heroine did it, and follows by considering herself the Evil-fighting heroine of a book like in the one she read and start following through the tropes inherent of this kind of story, notably being protected by Plot Armor. There's clearly something not right in her head!
- Soundtrack Dissonance:
- Part 8. Showdown between Koishi and Yukari Yakumo. What song gets played over it? Renai Circulation.
- Earlier, Carl Douglas' Kung Fu Fighting is played over a scene where Byakuren Hijiri is inciting a crowd of youkai to kill all the humans in Gensokyo.
- Let's not forget the Umineko theme in part 9, which is usually played at banquets or when someone is watching the shoreline. This is played while fighting Reisen II.
- That one doubles as a Mythology Gag and Fridge Brilliance because 'Dance of the Moon Rabbits' is also seen as the theme of the Chiester Sisters, who like Reisen II, are sniper bunny girls.
- Super Mode: Koishi and Satori have one letting them use their Combat Tentacles to near Lovecraftian levels as well as increasing their psychic powers. It manifests by their Third Eye merging inside their body and their left eye changing color (red for Koishi, black with a green vertically-slitted pupil for Satori) with a completely bloodshot sclera.
- Talkative Loon: Koishi will talk to anyone and anything, including her hat, any one of her replacement hats, and a door.
- Third-Person Person: Star when she's fighting Cirno.
- Torture Technician: Sanae when she subjects Kogasa to Cold-Blooded Torture, turns out that she had a lot of practice in her past.
- Reisen implies to be one when she incapacitate Reisen II.
Reisen: Don't worry, I'm good with captives. I might even say I'm looking forward to beating the info out of her.
- Unwitting Pawn: Strangely enough, the deeper the series goes, the more it seems Koishi herself is one of these. Turns out that she was an unwitting decoy used by the Watatsuki sisters to attract Yukari and have her assassinated in an ambush.
- Utopia: The first part of the finale reveals that Watatsuki no Toyohime, acting as an ambassador from the moon, helped the outside world achieve world peace, abolishing war and violence and suffering in the process. As anything that ceases to exist in the outside world finds a place in Gensokyo, this has some very dire consequences for Gensokyo.
- The Voiceless: Watatsuki no Yorihime.
- Wham Episode: 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, Koakuma reveals to have been Evil All Along, Satori murders Orin, Yukari is killed by Reisen II and Koishi turns out 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 the most violent and horrible episode to date!
- Why Am I Ticking?: A strange and horrifying variation: 1) They're fuse lit bombs. 2) They're sown into the stomachs of the victims. 3) The living bombs are fully aware of it.
- Woobie, Destroyer of Worlds: Sanae.
