Anticlimax Boss: Gengetsu was one of the hardest bosses in Touhou games, but was defeated by Yasora easily. Maybe she was holding back after hearing that Yasora was not going to use spellcards?
Beam Spam: Both the Twilight Spark and Ultimate Spark involve this—the latter by firing three Master Sparks and a Final Spark at once, the former by being ringed by crazy, curving lasers.
Butch Lesbian: Apart from her hair, Mokou fits this very, very well.
Butt Monkey: Fukakusa. Right after he was introduced, Fuka was attacked by Reimu's Anti-Yukari danmaku, threatened by Momiji, One-shotted by Ranma, and then Shikieiki comes out of nowwhere and starts pulling his ear. All within the span of two minutes.
Cannibalism Superpower: Mokou's powers over fire came from turning a phoenix into yakitori and eating it.
Cast Full of Gay: Averted, despite this being a Touhou roleplay. Komachi is straight and Suwako says she's "Hetrosexual".
Cat Girl: Kaori. Unlike the canon catgirls, she's neither a nekomata nor a kassha—just a generic cat youkai.
Character Development: In her first appearance, Yasora has shown big hatered to "this paedofile and her team of nineballs." But after talking with Yuuka later, she first went for a kiss.
Shujiko went from a depressed, silent character who only got involved to return shopping, and became a happier, easily flustered person by the end of the day.
Clothing Damage: Keeps happening to Kaguya and Mokou's had no shirt on for most of the story.
Shujiko's clothing suffered slight damage in her fight with Mokou, but her clothes are still intact and serviceable, at least.
Colony Drop: Yasora droped a sun on Gengetsu and Utsuho in the dreamworld. While riding on the top of it.
Comedic Sociopathy: A favoured method of character interaction, especially with the more resilient characters.
Combat Pragmatist: After several failed attempts of taking Yuuka's realm by force, Mugetsu tries somewhat more underhanded methods of claiming it.
Covert Pervert: Patchouli has a collection of erotica. Which Koakuma likes to read.
Creepy Child: Ranma... when she's not sleeping. and Panko, when you actually start listening to her or when she starts listening to the voices in her head.
Crossover: Kind of. Shujiko and Yasora are from a fanfic/comic respectively, each set in the Touhou-verse. Fukakusa is from another fanfic that has yet to be made
Curb-Stomp Battle: Yukari, Yuyuko, Komatchi and Mokou vs Reimu. Poor Reimu...
Shujiko VS Mokou, proving that freakish amounts of resolve can't quite overcome immortality.
Cute Ghost Girl: Ranma Saigyouji And the Cute Unnamed Onryo (named Panko) Panko brutally subverts this in Ecthel's Battle in the Center of the Mind, where Panko dips right into the Nightmare Fuel as her Onryo instincts take over.
Daddy's Girl: Implied for Mokou, given what she's been willing to do for him.
In the same scene, Elly was caught by Gengetsu in a similar situation, but was released when Chen broke free. Why? Mugetsu let go of Chen.
Dark and Troubled Past: Vaguely hinted at for Yuuka's back story near the beginning. Plus there's the mentions of her being pretty Ax Crazy until she 'settled down' in Gensokyo. Suwako also has hints of this as well, just it's never been brought up.]]
Determinator: Shujiko can become one if she draws upon her willpower.
Different as Night and Day: Mugetsu is willing to do anything to 'reclaim' her land from Yuuka's possession, even holding Chen hostage. Gengetsu likes to mess around and fight strong opponents other than Yuuka.
Yuuka's double (Usually summoned when casting Dual Spark) watched Flandre as she was tickled mercilessly in an old torture device lying around Yuuka's basement. While it was only for a few seconds, with no real consequences, the 'original' Yuuka wasn't amused at the inaction, blaming 'Yuuka 2' for Flandre even hiding inside it in the first place, and forced her clone to enter another device that melts bones.
Played With: Reimu's "Anti-Yukari" Defense system. It's a harsh way to deal with a prankster, but she was thinking that Fuka was a killer or a horrible monster.
Everyone is Bi: Also averted: in addition to Komachi being straight, Mokou is definitely a lesbian.
Expressive Accessory: Suwako's hat mimics Suwako's thoughts or feelings with its "eyeballs".
Fangirl: Patchouli and Koakuma to Mima, with Koa being the more fanatical case. Also the Mishaguji towards Mystia, especially the one that wears a replica of Mystia's hat.
Fanservice: Despite lacking any visual elements, it's present in spades. IN SPADES.
Forgets To Eat: Mokou, to the extent she hasn't eaten anything since making a phoenix into yakitori nearly 1500 years earlier.
Fridge Brilliance: What do magicians always say? That there's nothing up their sleeves. Where does Mima keep everything and anything? Her sleeves, even things that logically can't fit.
Ghost Amnesia: Yuyuko experienced this upon her death and subverted the trope like in Canon. Panko lost her memory (after being killed as a ghost) and has forgotten so much that she doesn't even understand what food is. After a night of rest though, she recovers
Going Commando: The Cute Unnamed Onryo is this, not actually understanding the concept of undergarments. Panko corrects this.
Have I Mentioned I Am Heterosexual Today?: Shujiko has to tell herself this quite a few times. Suwako also claims she's "hetrosexual", but seems to take likings to women as much as she does men.
Hot Blooded: Another thing that Will-Shujiko can be. Must be all that Shonen influence she was never exposed to...
Honour Before Reason: What Mokou says is the reason for her seeking revenge for her father.
Immortal Life Is Cheap: With many of the characters being invincible and able to resurrect, this is exploited a lot:
Mokou and Kaguya have died several times each and resurrected. In fact, the mechanics of one of Mokou's spellcards works by repeatedly killing herself.
Komachi has been impaled with her scythe. Being a shinigami, she just didn't die.
Suwako's had internal brain bleeding, has been impaled, and was Twilight Spark'd by Mima. Each time she either simply split herself or healed her wounds
The fairies, oddly are remarkably good at not dying.
Improbably Female Cast: Not only have the male characters merely been referenced—apart from a one-off gag—all the OC's are female, too. Then Averted with the advent of Fukakusa, the (sofar?) only male NPC and then Ecthel, the first Male PC. And now Youki Konpaku has turned up.
Interface Spoiler: During Utsuho's introdution she spoke normally. After she was hit in the head, her speech text turned gold. It's a major hint to her being possessed even for people unfamiliar with Touhou Nekokayou.
The Ill Fairy combines poor health with being a fairy. She's quite possibly more fragile than anything.
Mama Bear: Mima, towards Marisa—so much so that Marisa's father didn't dare do anything to Marisa so long as Mima wasn't sealed. Suwako as well towards Sanae.
maids, to the extent she's got maid outfits in her sleeves.
Me's a Crowd: Shinto Gods are able to split themselves indefinitely, something Suwako fully takes advantage of this and is multiple places at the same time.
Missing Mum: Marisa's mother hasn't been referenced, unlike her father.
Mythology Gag: The first one whom Reimu met was Yuyuko, and Reimu was treating her as stage one boss. Just what Yuyuko was in Touhou: Ten Desires.
Mood Whiplash: Given the various groups the characters have split into, it's quite possible to go from a battle to a discussion on the stars, to a game of hide and seek.
Fukakusa's prank. Revealing what seemed to be a serial killer horror story was actually nothing but a "revenge" prank.
Mundane Utility: Reimu can use ofuda as protection from rain when she doesn't have an umbrella.
Nosebleed: After being soaked in water and having her neck snapped, Mokou's sarashi was in considerable disarray. This was the reaction from Kaguya and Shujiko.
Koa has had a nosebleed that knocked herself out when she was thinking about Mima in a swimsuit
Aya had to do something for Rin to borrow her wheelbarrow. All we know is that it's embarrassing and there's pictures of it on Aya's camera.
How in the world did Fukakusa and Aya's Prank War begin?
No-Holds-Barred Beatdown: Natsumi tried issuing one during the final battle, binding everyone and unleashing a holy amount of danmaku. In response, everyone present during the battle are using their strongest cards on a defenceless Natsumi, essentially giving her the beat down.
Ofuda: Yukari used them to place plates and cups for a meal in the sky.
One Hitpoint Wonder: Mokou, due to centuries of neglecting her health and not bothering with defences, is even easier to kill than Cirno.
One-Hit Kill: Ranma pulls this off against Fukakusa, killing him with a single punch. The impact and the sheer force of the punch was what killed him, not the fist shapped hole she put through him.
One of Yuuka's wild theories as to what could be causing the incident near the beginning of the RP was a reference to the mind-screwy touhou doujin series, Jasper Star.
Smoking Is Cool: Mokou certainly falls under this. It's not as if it can kill her or make her health any worse, though. Kaguya occasionally gets in on it, too, which is behind the Noodle Incident fire in canon.*
Mokou accidentally incinerated Kaguya's head and set the forest on fire when lighting a cigarette.
Stringy-Haired Ghost Girl: The Panko is a Onryo, a vengeful spirit who returns to the mortal world for revenge. This being Gensokyo And her being a Goddess when alive, she's actually subverts the trope and the usualOnryonature. Doesn't stop her desires for revenge though. For at while at least.
Thanks for the Mammary: Komachi in her sleep did this to Aya. Something tells This Troper That it won't be the last time this happens in this RP.
Fukakusa may count too: to start a prank in Hakurei shrine, to scare Hot Blooded shrine maiden and then to turn his back to her and drop guard. Even though he couldn't have foreseen Reimu's reaction (due to never meting her) she's a Hakurei shrine maiden, he should of known better.
