->''The thing that keeps me going? I screwed up once. I'm not going to do it again. It's the same for a friend of mine, too…''
->-'''???'''

It's January of 1999, and a high school transfer student is waiting at the train station for her cousin... hold up.

''Canon in G'' is a GenderFlip fanfic of ''VisualNovel/{{Kanon}}'', and by that we mean '''every''' version of ''Kanon''. Not just the visual novel and not just the KyotoAnimation version -- this has elements of everything from Toei's adaptation to the manga (both the more faithful version and the very AU ''Kanon Another Story: Wonder Three'') to official art to collectible card games. The very first passage also introduces ideas from the other games in the Seasonverse: ''VisualNovel/{{AIR}}'' and ''VisualNovel/{{CLANNAD}}''.

Yuuko, our Yuuichi proxy, is a snarky, trollish, but caring girl who's searching for her memories in a more complex timeline than what we've seen, and there seem to be more eyes out looking after what goes on around her. "After all," the author's introduction states, "every version of ''Kanon'' has its surprises."

----
!!'''This fanfic contains examples of:'''
* AbsurdlyPowerfulStudentCouncil: It's mentioned that Kuze would really like this to happen and has occasionally invoked it (with the plagiarism investigation).
* ActorAllusion: The female Kuze now has a first name: Hiroka. Aside from being an actual name that somebody would give their kid, it's also a contraction of '''Ka'''miya '''Hiro'''shi, Kuze's voice actor from Kanon 2002. (Her character design is more in line with the 2006 version, though.)
* TheCanKickedHim: The conversation between Kaori and Yuuichi about Hanako-san the washroom ghost is brought into this fic but reversed, as Kaoru becomes aware of the whole "demon" situation before Yuuko does.
* BananaPeel: One of Makoto's prank ideas. Yuuko can't believe he actually tried it.
* BroadStrokes: There are parts of every version of ''Kanon'' in here.
* ClingyJealousGirl: Kitagawa Junri is practically obsessed with getting Kaoru to notice her and accuses other girls of getting too close to him.
* DeadpanSnarker: Yuuko, with shades of Kyuuichi. Mahiro also has his moments.
->'''Mahiro:''' …That's not an ikiryou. That's a demon. Learning the difference is helpful.
* EmbarrassingCoverUp: Kaoru tells Yuuko not to speak of their phone call where Kaoru asked, in a roundabout way, about the demons. Yuuko promptly tells Junri that they were discussing Kaoru's "embarrassing rash".
* FantasticRomance: It's ''Kanon'', and it doesn't look like it's going for an Iori or Yuki end.
* GenderBlenderName: The male Makoto keeps his female version's name. However, Jun, owner of another Gender Blender Name, becomes Junri.
* GenderedOutfit: Aside from using the male and female school uniforms on the opposite characters, the story also adapts characters' signature outfits (particularly their expanded wardrobes from the 2006 show) as men's or women's clothing, though nothing is fanserviced up. Makoto has a military cap instead of hair ribbons, whereas Sayuri's hair bow becomes Satoru's tie.
* GenderFlip: The premise. A number of differences separate this from any version of ''Kanon'' -- in particular, drawing from all of them instead of just one -- so it isn't a straight RuleSixtyThree, despite being inspired by the popular [[VisualNovel/{{CLANNAD}} Sunohara Youko]].
* GhostStory: When Iori is explaining ikiryou to Makoto, it quickly becomes this as he starts having way too much fun with it.
* GirlishPigtails: Junri has them.
* ItWillNeverCatchOn: Kaoru's opinion of camera phones.
* JerkWithAHeartOfGold: Yuuko is a Key protagonist, after all.
* LateArrivalSpoiler: For the original work. Iori is referred to as "[[spoiler:Misaka Iori]]" in his introductory chapter, and when Mahiro meets Ayumu a second time, he immediately [[spoiler:reports that he's seen an ikiryou]].
* LongHairedPrettyBoy: Mahiro.
** SamuraiPonytail: He keeps Mai's hairstyle.
* LoveMartyr: Yuuko starts to think of Junri as one after Kaoru takes her for granted one too many times.
* LowerDeckEpisode: Chapter 4 contains a few brief Yuuko scenes and no Ayumu at all, and instead focuses on Makoto, Iori, and Mahiro.
* MillenniumBug: Yuuko's computer teacher is exasperated already at the rampant notion of a bug that would destroy technology as we know it, and it's only January 8th, 1999. The next year will probably not be kind to him.
* MusicalThemeNaming: The chapters themselves. Like in ''Kanon'' 2002, they're named after songs from the OST, but in this all the names are varied; for example, Last Regrets becomes First Remembrance.
* MysteriousEmployer: Mahiro has someone he's helping out - though it seems to be a mutual assistance thing - who knows about the "demons" in the school.
* TheNineties''/''TurnOfTheMillennium: The setting.
* NonuniformUniform: Satoru is allowed to wear a tie even though there isn't one in the uniform guidelines.
* OddFriendship: Makoto and Iori, although Makoto and Shiori rarely ever meet in any official version of ''Kanon''.
* PunBasedTitle: Meaning both "a variation upon {{canon}}" and "a variation upon ''Kanon''", and a reference to Pachelbel's Kanon, the namesake of the original game.
** DoubleMeaningTitle
* TheStationsOfTheCanon: Used on occasion but always twisted at least somewhat. By varying the characters involved and occasionally switching roles, chapter 4's callbacks to canon are at times unrecognizable.
* VerbalTic: Every single one of them is kept, unmasculine or not.
* YouAreTheTranslatedForeignWord: When Iori explains the concept of an "ikiryou", he adds "That's why they're called 'living spirits'."
