Fandom Specific Plot: Touhou

  • Touhou has innumerable doujins/fanfics detailing the Backstory of the characters, since not many characters have one to begin with, and even if they do it's still pretty vague. By far the two most common recipients are Rumia (so popular that any fan referring to "EX-Rumia" is immediately understood) and Sakuya (serial killer, former monster hunter, or Lunarian being the three main theories).
    • Touhou Tonari and Though the Wind Cries are good examples of this.
  • Explaining what happened to the PC-98 characters, especially Mima, is similarly widespread.
  • Detailing the future of characters is also common, as amongst the incredibly long-lived youkai there are a few humans that will die relatively soon. Reimu, Marisa and especially Sakuya (again) are the targets, though Sanae became increasingly popular after her arrival.
  • The "Outsider Fic" subgenre, where somebody (often an Author Avatar, but may also be any kind of original character) somehow ends up within Gensokyo, either by accidentally/purposefully slipping through the Hakurei border (which, according to canon, is common), or by Yukari (in a sub-subgenre increasingly known as "Gappy Fics"). As a result, Fish out of Water antics ensue as they get acquainted with this Fantasy Kitchen Sink, and the outsider must either learn to live in this new land or find a way back home. Occasionally, they'll arrive just as an incident begins and they're forced to take part in it for one reason or another, teaming up with the canon characters. A fine example of this is ChibiChen's Mind The Gap.
    • There is also the So Bad, It's Good subgenre of "Gappy Stu Fics," wherein an Author Avatar is gapped into Gensokyo by Yukari, makes friends with several of the residents, becomes super strong after training with Reimu and Marisa, and beats up a bad guy in one of the worst incidents to ever hit Gensokyo. These fics start hundreds of subplots due to Loads and Loads of Characters, but never answer them before the readers just give up. This subgenre was taken apart by Diamond In The Rough, showing the shallowness of these self-insert characters while addressing how dangerous Gensokyo can really be.
    • The plot of Urban Legend in Limbo turns out to be one of these, where newcomer Sumireko Usami tries to break through the Hakurei Barrier in order to interact with Gensokyo's residents. However, it's Deconstructed in that her actions threaten to completely destroy the Barrier, once she actually gets in, she gets fed up with the constant Danmaku fights with everyone and the Lunar Capital snuck their own power stone in what's most likely an attempt to connect the Lunar Capital with Gensokyo.
  • The (mis)adventures of Team 9, an entirely fan-made Cast Herd consisting of child-like "low level" youkai, seems to be required for every significant story, even if only as a background detail. Indeed, the Non Indicative First Chapter of Imperfect Metamorphosis, and ultimately the entire story, is based around them.
  • "One or more characters get turned into children" is also an oddly common plot.
  • Since the setting already relies on a system of formal duels to settle disputes, a common Excuse Plot (particularly for fangames) is "Yukari got bored and changed the system, so now the duels take the form of mahjong/soccer/etc.".
  • The four great Fandom-Specific Explanations of Touhou are summed up by a well-known meme, namely this doujin panel. (Which has actually been altered from the original, which just had the first three lines.)
    • Magic: Magic in Touhou is not overly defined, so it can be used to justify whatever need be justified.
    • Eirin's shady new drug: Eirin's tendency to make unusual concoctions of dubious pharmaceutical benefit and bizarre effect is often used to justify strange happenings. Inaba of the Moon and Inaba of the Earth, generally considered canon, uses this one.
    • Yukari is fooling around again: Yukari is extremely powerful, extremely lazy, and extremely capricious; the plots just write themselves.
    • It's a Moriya Shrine conspiracy: After their introduction in Mountain of Faith, the next three "main" games in the series (Subterranean Animism, Unidentified Fantastic Object, and Ten Desires) were either directly or indirectly caused by the Moriya trio's (more specifically Kanako's) attempts to gather more faith from the population. Suffice to say fanon took it and ran with it.
    • Templates like that are forbidden: Marisa says this in response to the above list. In more comedic stories, this has occasionally been used as an actual excuse for the plot.
