"Do you know the title of this song? It's Canon. Pachelbel's Canon. It repeats the same melody and crescendos gradually, peacefully, and beautifully. It would be nice if life changed like that: slowly but surely, while being seemingly unchanged from day to day."

to girls, it's actually a seinen

one and the 2006 Kyoto Animation
one), CD dramas, a manga, a series of light novels, an Alternate Continuity

.Ordinary High-School Student
Aizawa Yuuichi used to visit his aunt Minase Akiko and cousin Nayuki in their quiet little town every holiday, but one year something happened and he left for seven years. When he transfers
to Nayuki's high school, his memories of that time remain a blur.
Upon his return he encounters a number of mysterious girls from his past who all need his help. Bokukko
taiyaki-thief Ayu searches for a precious lost item she cannot describe. Quiet and serious
Mai hunts demons in the school after dark. The childish tsundere
Makoto suffers from amnesia and has no place to go. The sickly
Shiori is estranged from her sister and never present at school. Finally, there's the lonely Nayuki, weighed down by rejection and tragedy.
Yuuichi resolves to help them, but as he gets involved, he discovers that there is far more to the girls than meets the eye. Mystical happenings lie hidden in this strange town, tied to Yuuichi's forgotten past. In dealing with the girls, Yuuichi must face his lost memories. What happened seven years ago, and why can't he remember?
Absolutely not to be confused with this Kanon

Character Page under construction here:
This franchise provides examples of:
- Absurdly Sharp Blade: Mai's sword. While it wasn't a clean cut, she still breaks a brick wall with it. (Also, when thrown, the sword tends to sink deep into floors, walls, tables, as if they were made of half-melted butter.)
- Yet strangely averted, as it can't even cut a banana. It doesn't affect how it hurts demons, so Mai doesn't really care, but it seems to contradict how the sword sunk into the floor during one of the earlier battles.
- Action Girl: Mai Kawasumi.
- Adaptation Induced Plot Hole: The game shows that, under normal circumstances, ikiryou whose natures are discovered are forgotten and unable to be seen, and even if their natures aren't discovered, they eventually fade from view and memory anyway. None of the adaptations cover this, aside from showing Ayu asking Yuuichi to forget her and Yuuichi refusing. While one can extrapolate that Yuuichi then wished to not forget Ayu and thus her miracle protected him (skipping over the part in the game where he does start to forget and then remembers), not having the universe rules spelled out in Kanon will then throw you for a loop when you watch CLANNAD.
- Aloof Dark-Haired Girl: Mai is very quiet, inexpressive and difficult to read. Unfortunately, this just leads to her weirding people out.
- Armor-Piercing Question: "Yuuichi, are you a miracle worker?"
- The Artifact: Being one of the first visual novels, the game incorporates a calendar system from the older type of "micromanagement hell" dating sims. Everything happens sequentially rather than on any specific date, however.
- As You Know:
Nayuki: It's lunchtime, Yuuichi-san!
- Badass Adorable: Mai.
- Balanced Harem: Even if it is not a case of Marry Them All in the end, the plot strives to give all five girls roughly equal time and make them all plausible choices for Yuuichi.
- Beta Couple: Kitagawa and Kaori in the 2002 version's OVA episode, where they finally hook up with each other after Kitagawa's efforts.
- Big "NO!": In the English dub of the 2006 series, Yuuichi gives one after Ayu's apparent death. The Japanese version has him screaming Ayu's name instead.
- Bishōnen: Yuuichi◊, but only in the 2006 anime, not the original game.
- Bleached Underpants
- Boke and Tsukkomi Routine: Played with by Sayuri and Mai.
- Bokukko: Ayu. Yuuichi even tries to get her to switch first person pronouns, but his suggestions just make her uncomfortable and she immediately reverts to her old ways.
- Butt Monkey: Kitagawa in the 2006 anime, big time.
- Cast from Lifespan: Makoto is able to become human at the cost of her memories and her life.
- Catch Phrase
- Nayuki's "Faito da yo!" and "Usotsuki!" ("Liar!")
- Shiori's "I dislike people who say things like that."
- Akiko's "Approved."
- Ayu's "Uguu."
- See also Verbal Tic, below.
- Chekhov's Gun
- Chekhov's Gunman: Mishio in Makoto's arc, and in the Kyoto Animation version, all the major girls.
- Childhood Friend Romance: Nearly every haremette and Yuuichi, as it's the theme.
- Childhood Memory Demolition Team: Twisted. Both demolitions (the barley field and the tree) were done right after Yuuichi left town as a child, so he barely had those memories when he returned, and he didn't really want to remember the tree, either.
- Clap Your Hands If You Believe: The comatose Ayu still believed enough in her promise to Yuuichi and the wishes that she made on a simple crane machine doll that she was able to spiritually project herself as a solid living being even seven years later.
- Also shows up in a much darker form in Mai's story. Her unrealized powers lead to the "monsters" she made up to try to keep the young Yuuichi from moving away manifesting as quite real - and quite dangerous.
- Club President: Nayuki, of her track team.
- The Comically Serious: Mai, especially when paired with Sayuri. A brief Imagine Spot from Yuuichi has Sayuri translating Mai's "..." with phrases such as 'shut up' and 'drop dead'.
- Compressed Adaptation: Several short manga based on the heroines' stories have been made: two normal series that take on the story in two volumes. There is also a five-volume light novel series.
- Conspicuous CG:
- Continuity Nod
- Converse with the Unconscious: Yuuichi goes to talk to Ayu's comatose body after he discovers the truth about her.
- Crash-Into Hello: Uguu~mmphff~!
- Cruelty Is the Only Option: In the Visual Novel, Yuuichi will end up with one girl. What happens to the others? Mostly, they die. Thankfully, this is averted in the anime.
- Cute Little Fangs: Makoto. Also foreshadows her true nature as a fox.
- Cutting Off The Branches: In the visual novel, there are five separate girls with five separate storylines, but Yuuichi/the player is only meant to experience one arc. Playing out the other girls' storylines requires playing the game again. The 2006 anime adaptation, however, has four of the five arcs happen sequentially. This results in some confusing characterization. For example:
- Yuuichi develops a close bond with Makoto. She dies and he's upset, but by the next episode, he's back to normal. He has another intense experience with Mai, but once her plot from the visual novel is complete, Mai no longer appears in the show, even though she's presumably still alive and in town. Yuuichi neither mentions nor visits her. Shiori receives the same treatment as Mai; after her arc, she is not mentioned and no longer appears, even though Yuuichi has formed a close friendship with her.
- Once the previous girl's arc has been completed, some of the supporting characters of the previous arc (Amano for Makoto, Sayuri for Mai) also disappear from the show, without any exit for the characters.
- This is all a product of making separate plotlines take place one after the other. The visual novel ends once it reaches a conclusion for one of the girls, and each alternate arc is a replay. For each new arc, Yuuichi is largely written as though he never experienced the previous arc and never bonded with those missing characters. In a replay of a visual novel, where each arc is a separate continuity, this makes sense. In the anime, where each new arc takes place after the previous arc, it's awkward and jarring.
- There's some attempt to patch this: in Episode 23, Yuuichi finally mentions the previous three girls and cries, but it makes little sense that Yuuichi is only upset about them now and didn't spend any more time with the two who were still alive. In Episode 24, all the missing characters return, but their absences remain unexplained.
- Makoto has a very good reason for why she doesn't appear again and Mai's and Sayuri's reasons are explained however
- Dating Sim
- Deadpan Snarker: Yuuichi.
- Debut Queue: In the anime, everyone who counts is present in episode 1... but for most, it's easy to miss.
- Defrosting Ice Queen: Makoto.
- Deus ex Machina: The anime's ending is a little too convenient for some.
- Especially the ending, which has the entire cast magically healed. Even by the show's standards, and that's saying something.
- Did I Just Say That Out Loud?: Yuuichi narrates meeting Kaori, which she responds to:
Yuuichi: As I turned around, Kaori Misaka was standing there.
- Disappeared Dad: Mai and Nayuki live with their mothers, and have since they were little; Nayuki admits that she can't even remember what her father looked like, and Mai's is never mentioned at all.
- Does Not Like Men: Sayuri in the game.
- Dogged Nice Guy: Kitagawa.
- Downer Ending: Makoto's route in the original VN. The only bright spot is that Yuuichi and his friend figure that someday they'll get over it... someday.
- There are also two bad endings on Mai Kawasumi's path. Given just the right choices, you can either get killed by a demon or watch her fall apart without Sayuri's friendship.
- Luckily, its averted in the anime, although they repeatedly sucker punch you before you get to the end.
- Driven to Suicide: Three characters.
- Shiori, due to her terminal illness and Kaori's rejection. It doesn't work.
- Sayuri, due to the death of her little brother. It doesn't work either.
- Mai, during the "good" ending. It works, but she gets better.
- Dub-Induced Plot Hole: Yuuichi's breakdown when talking to Makoto (the real one) near the end of the 2006 anime has him accidentally say "when I was seven" instead of "seven years ago" in the dub. Kanon may not officially state the characters' ages, but it's clear from context that Yuuichi is seventeen, not fourteen.
- Early-Bird Cameo: The real Makoto briefly appears in the background of a much earlier episode than her actual introduction. Light orbs also explicitly appear to end arcs in the anime.
- Earn Your Happy Ending: Yuuichi has to go through a LOT before the finale in the anime. Expect a lot of heartbreaking pain first, though.
- Easy Amnesia: Memory loss is a theme of the work. The anime expands on it by saying that memory is part of the price you pay for creating a miracle, which is a very workable theory.
- Yuuichi can't remember what happened seven years ago.
- Ayu can't remember what she's looking for, when she lost it, or where it is, but she knows it is important.
- Makoto can't remember anything about herself besides her name and that she has a grudge against Yuuichi.
- Emotionless Girl: Mai. At first.
- Erotic Eating: Mai in episode 12◊.
- Featureless Protagonist: Yuuichi in the original game, making him one of the only Key protagonists to be drawn in this way.
- First Kiss
- Foreshadowing: A veritable masterclass. Just how cleverly the dialogue is written - everything said has at least one other layer of significance — can only be fully appreciated on repeat viewings. The anime adds a little more.
Ayu: Why are you standing there?
Yuuichi: I'm scared of heights.
Ayu: Actually, I'm not good with heights either.
- Forgotten First Meeting: Yuuichi knew Ayu as a kid, but he forgot about her due to Trauma-Induced Amnesia after her accident. Yuuichi also knew Mai and (sort of) Makoto as a kid, but he doesn't remember them anymore.
- Flowers for Algernon Syndrome: Makoto.
- Freeze-Frame Bonus: For just a second in Episode 6, when Yuuichi and Ayu are in the cafe after going to the movies the adult Makoto can be seen walking by outside the cafe.
- Also for just a fraction of a second Episode 14, when Yuuichi and Sayuri are in the cafe, you can see a scar on Sayuri's wrist, hinting at a suicide attempt (mentioned more explicitly in the game).
- The Gadfly: Yuuichi, who enjoys annoying his love interests so much that it's nearly his defining character trait.
- Generation Xerox: Akiko and her daughter Nayuki. Akiko sleeps less and runs less, but they look almost the same, have very similar personalities, and even crack the same jokes.
- Generic Cuteness: The show is so heavily loaded with moe characters, it's just about impossible to guess which ones are intended to be attractive in-universe (Leads to Informed Attractiveness). That said, the non-speaking and one-or-two-line characters look even more generic — almost interchangeable — yet they're far less cute than the major characters.
- Genki Girl: Ayu. The other characters even keep commenting on how "genki" she is.
- The Glomp: Ayu tends to combine this with a running tackle. Leads to a Crash-Into Hello Once an Episode.
- Go Out with a Smile: Poor Makoto after her "wedding" with Yuuichi, making him possibly the youngest "widower" in romantic anime.
- Gratuitous German / Foreign Language Title: The title of the franchise is taken from Pachelbel's Canon (Kanon in D-dur), which figures periodically in the 2006 anime. Alas, the franchise gets the meaning of the word "canon" all wrong. The confusion derives from the fact that Pachelbel's Canon happens to be both a canon and a passacaglia (or a ground base, which is more or less the same thing). Passacaglia is the forerunner of the theme and variations, and that, rather than a canon, is the basic musical form the franchise is loosely organized around. Four of the five paths in the original Visual Novel have links both to Yuuichi's forgotten past seven years ago and his childhood promises from then, along with supernatural elements, and a girl who needs his help (and love). Each girl, and the path she represents, is a variation on a theme. By contrast, a canon need not have the structure of a theme and variations; it fact, it seldom does. Rather, a canon is a musical form defined by its use of exclusively strictly imitative counterpoint (in contradistinction to a fugue, which employs both strictly imitative and freely imitative counterpoint) — although said "strict imitation" can nevertheless run backward or upside-down or any of dozens of other complex tricks, so long as the pattern of intervals remains unchanged.
- Head Pet: Pirozhki
- Heavy Sleeper: Nayuki. The Visual Novel explains the psychological reasons behind her behavior. This leads to some amusing non-thudding non-sequiturs delivered in her barely-ambulatory state.
- Idiots Cannot Catch Colds: In the 2006 version, after Yuichi and Ayu are done visiting Mai at the hospital they bump into Shiori on their way out. She asks them if they're there because they have colds too, and Yuichi invokes his own twist on this trope by telling Shiori that, "Uguu never gets sick." The English dub renders his adage as, "An Uguu a day keeps the doctor away." Ayu is not amused in either language.
- Infant Immortality: The feline variant is used with Piro. He lives out in the cold, gets thrown off a bridge, lives in a house with someone who's allergic to him, gets stepped on, gets dunked in the bathtub in the game, and he lives just fine.
- Ill Girl: Shiori. Later, others as well.
- Informed Attractiveness: Necessary, on occasion, because of the extreme Generic Cuteness and overall moe-level of every female character with more than a few speaking lines.
- Inner Monologue: In the original game.
- It's All My Fault: Several, but the most dramatic would be Nayuki after Akiko gets hit by a car.
- I Want My Beloved to Be Happy: Nayuki.
- This trope is implied to be the third wish that Ayu wished for while in a coma, the miracle that managed to save everyone that Yuuichi cared about. Yuuichi discusses it at length with Shiori in the KyoAni anime.
Shiori: I don't know what exactly she wished for, but maybe, 'I want my dearest person to always be smiling'. Maybe it was a wish like that.
- Jerkass: Kuze from the student council; even moreso in the original game than in the 2006 anime.
- Jerkass Fašade: Kaori counts as this when Shiori is involved, especially in the anime.
- Kidanova: Yuuichi's harem is established when he's ten. Which may be the universe's advance payment on the future tragedies that befall them.
- Kissing Cousins: The Nayuki option.
- Laser-Guided Amnesia: Happens to a lot of characters, all for reasons relating to the town's miracles and the tragedy seven years ago.
- Last Episode New Character: The Toei version of Mishio.
- Last Girl Wins: In the 2006 Kyoto Animation version, all of Yuuichi's important romantic options are introduced — or at least glimpsed — in the first episode. But the episode ends with Yuuichi and Ayu together. Ayu is also the First Girl, the Last Girl, and the closest thing to a protagonist in both the opening and closing credits. See also First Girl Wins.
- Late for School: Nayuki became the track team captain because her sleeping habits trained her to run quickly to school.
- Lethal Chef: Played with in the case of Akiko, an otherwise marvelous cook who nevertheless makes something as monstrously revolting as "that jam".
- Ayu's first cooking attempts can't even be eaten for the sake of politeness — they're so badly burned they'd break teeth, even her toast. Eventually Akiko and Nayuki teach her how to cook.
- Limited Wardrobe
- Look Both Ways: Akiko is hit by an SUV, but survives thanks to Ayu's miracle. Details of the accident itself slightly differ in game and anime adaptation.
- Magic Skirt: Mai when she jumps off the school building to defend Yuuichi from the "last demon"
- Meet Cute: Yuuichi meets almost every available girl in an odd manner. To wit:
- Ayu literally runs into Yuuichi before dragging him off with her, an irate taiyaki vendor in hot pursuit.
- Shiori meets Yuuichi after Ayu faceplants into a tree and said tree drops its snow on her.
- Yuuichi meets Mai and Sayuri when Nayuki tumbles down the stairs into them.
- Makoto first appears punching Yuuichi for a slight he committed that neither of them can even recall.
- Nayuki, the First Girl, is a tamer example of Meet Cute — but even she arrives two hours late to meet Yuuichi at the train station. Outside, on a bench. In a snowstorm. Of course, they already know each other, being first cousins. Then again, Yuuichi already knows most of the other girls from ten years earlier, anyway. But he's forgotten them.
- Memento MacGuffin: Ayu's hairband.
- Mobile Shrubbery: In Makoto's first appearance in the 2002 anime, she stalks Yuuichi in a Cardboard Box.
- Mood Whiplash: The ending theme of Kanon 2006 is an upbeat pop song that can create some mood whiplash when it starts playing after an especially sad or dramatic episode.
- Mr. Fanservice: Yuuichi, depending on your view.
- Musical Spoiler: If you check the track list, Makoto's theme is called "The Fox and the Grapes". This references the fable of the same name and shows that Makoto's spite towards Yuuichi was only because she couldn't stay with him when they were younger, just like the fox in the story only spited the grapes because he couldn't reach them. On a simpler level, it also shows that she's a fox.
- New Game+: Replaying Mai's route in the VN allows you to see Sayuri's mini-route.
- New Transfer Student: Yuuichi. Many students are disappointed to see that he isn't a cute girl.
- Not a Morning Person: Nayuki
- Not Quite Dead: Shiori and Ayu.
- Not So Weak: Mai. Obviously, she's a demon-killing badass in her own way, but she's also very selfless. Hell, she lets a dog try and eat her hand after it was attacking people because she had nothing to feed the thing. See also: Constant abuse from student council, other students and teachers.
- Once an Episode: Ayu runs into Yuuichi. This doesn't, however, happen at the end of the arcs of all the other girls, but there's a reason for that.
- Parental Abandonment: Ayu's father and stepmother are said to be out of town, and she can't reach them. Yuuichi's parents are out of the country, and Makoto's amnesiac and can't find her parents, if she has any.
- Parental Substitute: Akiko. If you're homeless girl who needs a roof over her head and 3 square meals a day, just ask and you'll have an instant family of your own, no background check of your shady past needed. She goes as far as to say "Come play with Mommy" to Makoto as the latter begins to lose her memories.
- Perfect Health: Shiori initially Hand Waves her skipping of classes and lack of energy as "a cold." While this excuse rapidly wears thin, the heartbreaking revelation is somewhat spoiled by the audience being well aware it could only be a fatal condition.
- Pinky Swear: Yuuichi and Ayu's relationship is marked by several of these.
- The Pollyanna: Ayu.
- Post-Episode Trailer
- Pretty Freeloaders: Makoto starts out as a Pretty Freeloader before becoming an Unwanted Haremette. And Akiko, who is not one of the available girls but the mother, lets the girls have the run of the house and talks Yuuichi into helping them out when he doesn't want to; the only thing keeping her from qualifying is that she's the one that technically heads the house.
- Really Dead Montage: Except that she's not.
- Real Men Hate Sugar: Yuuichi openly expresses that he hates sweets, and is delighted that Akiko's "special jam" does not taste sweet... until he tasted the jam in question...
- Ret Gone: In Ayu's route in the game, the ikiryou Ayu when she disappears is forgotten by everybody
- Romantic Two-Girl Friendship: Mai and Sayuri.
- Say My Name: "AYU!" near the end of her arc, and "MAKOTO!" in Toei's adaptation of hers.
- Scenery Porn: The Kyoto Animation version.
- Screwball Serum: Akiko's "special jam" is so infamous that Yuuichi and Nayuki beat a hasty exit everytime somone is about to try it.
- Second Year Protagonist
- Self-Harm: Mai. Taken furthest in the adult-version of the game. Sayuri's getting brutalized by demons when she was trying to bring Mai the surprise birthday present, devastates Mai so she surrenders her body to Yuuichi. She feels no respite after the act, since with Yuuichi it didn't feel like a punishment. Other adaptations skip to her resorting to the sword.
- Shout-Out: In the 2006 anime, lots of them, mostly to other Kyoto Animation shows. The first few episodes are riddled with Shout Outs to ''Haruhi Suzumiya' that depend for their humor on having the same seiyuu playing both Yuuichi and Kyon.
- Every so often in the 2006 version you can see a bus drive by with a peach juice drink logo on the side, this is a shout out to Air since the drink depicted is Misuzu's favorite. There's also a trolley with an ad for Nagamori (the surname of one of the heroines of ONE) Milk.
- There's another Shout-Out to ONE episode 17, with Expies of Akane and Rumi visible in the background during the cafeteria scenes.
- Also in the 2006 anime, Yuuichi wears a LOST shirt briefly in the last episode.
- The last episode of the 2002 anime has Kitagawa wearing a shirt with CLANNAD written on it - sort of an Early-Bird Cameo, since the game didn't come out until 2004.
- To Disney's Sleeping Beauty, of all things, in episode 12 of the 2006 anime - an orchestral version of "Once Upon a Dream" plays when Yuuichi sees Mai in her ballgown, and again during their Dance of Romance.
- Sitting on the Roof: Yuuichi goes up on the roof to talk to Mishio.
- Snow Means Death: The 2006 version of Kanon has Yuuichi searching for Ayu in a raging blizzard, then giving up and waiting for death. There's also the Look Both Ways incident, which was made more dramatic with the scene of red mixed in the snow. And when Makoto dies, a previously completely green area was instantly covered in snow.
- Snow Means Love: Kanon is the ultimate Snow Means Love series (and the inspiration for Sad Girl In Snow before it was merged with Fragile Flower) and one of the few works of Key Visual Arts with a happy ending. Oddly enough, Yuuichi himself hates snow. Of course, he probably has good reasons for that.
- Soap Opera Disease: Shiori.
- Something Something Leonard Bernstein: The English rap segment of the ending. Something something something EVERYBODY AND THEIR MAMA KNOW I GOT IT GOIN' ON! Somewhat out of place.
- Spoiler Opening: Game and second anime.
- Stepford Smiler: Sayuri, and she admits it freely if questioned about her odd habits.
- Supernatural Fiction
- Swiss Army Tears: Deconstructed in one route. Mai Kawasumi cures her mother with her tears, and people eventually learn that her tears have the ability to rejuvenate anything, even after it has died. Unfortunately, since she's living in a modern setting, she gets swept up in a media circus that publicizes her powers, gets persecuted by the people around her for being different, and is eventually forced to leave her town.
- Themed Harem: Childhood friends, with Shiori the odd one out.
- There Are No Therapists: The girls' mental health thrives on Yuuichi helping them to discover their own strength, and just Yuuichi. Then again, a school nurse wouldn't help Mai if they had one because the administration hates her, Nayuki's main source of support, her mother Akiko, is hospitalized at the exact time that she needs her the most, Makoto's an animal in human form, Ayu's an astral projection, and Shiori isn't even supposed to be out.
- Third-Person Person: Both Sayuri and Makoto.
- When doing a narration, oddly enough, Sayuri uses 'Jibun' and drops her cutesy voice.
- Threesome Subtext: Yuuichi/Mai/Sayuri. All three relationships are emphasised to be strong, they spend much of Mai's route all together, and near the end there is an extended sequence where Yuuichi imagines the three of them all living in the same house together and being incredibly domestic with one another.
- Title Drop: The above page quote.
- Tomato Surprise: The true natures of both Makoto and the demons Mai is trying to kill are pretty big tomatoes by themselves, but the author pulls this twice in fairly-rapid succession with Ayu: 1) when Yuuichi first remembers her falling from the tree, and then 2) when Akiko tells him he's mistaken — she's not dead, just in a coma.
- Tomboy and Girly Girl: Nayuki and Ayu as rival love interests and Mai and Sayuri as friends.
- Trademark Favorite Food: Ayu's taiyaki, Makoto's nikuman, Nayuki's strawberry sweets (especially sundaes), Mai's gyuudon, and Shiori's vanilla ice cream.
- Tricksters: Yuuichi and Makoto bring this out in each other. Makoto nearly always gets the worse end of the deal; for all her effort, she's not all that skilled at trickery. Ironic, since she was actually a fox before a wish turned her into a human. (It's also quite likely she loses, at least in part, because she's in love with Yuuichi and what she really wants is to play with him, rather than actually defeat him. In fact, her whole reason for becoming human was to return to his side and spend time with him before her death.) See also Troll.
- Troll: Yuuichi really seems to enjoy the reactions his snarky comments and strange explanations get. It helps that the girls are generally very gullible, but they start to catch on somewhat.
- Tsundere: Makoto.
- Unbuilt Trope: One of the first games that used the plotline of "guy meets a number of very troubled girls and solves all their problems (or just the one you picked) while they all (or the one you picked) fall in love with him". Harem Series meets Intimate Psychotherapy as described above is now dirt common. Thing is, though, in all but one route of Kanon comes the Awful Truth that Yuuichi caused the girl's problems and screwed up her life unintentionally for the past seven years. Less "I'll solve your life issues and then you can date me" and more cleaning up your own mess.
- Unstoppable Rage: Don't hurt Sayuri when Mai's there to see it.
- Verbal Tic: Ayu's "uguu", Makoto's "auu", Nayuki's "nyuu" when she's sleepy, Mai's "...", Sayuri's "hoe" and "ahaha".
- Ayu's immaturity and repeated usage of the tic "uguu~" are all justified by the fact that she's basically still ten-year old Ayu Tsukimiya being projected by her comatose self.
- What the Hell, Hero?: Some of the choices in the game lead Yuuichi to do some really nasty things to the girls that only serve to make him look like an utter asshole. One notable example being stomping Ayu's taiyaki bag into the snow.
- Appropriately enough, Yuuichi gives Makoto a major one after she drops Piro off the bridge.
- A Wild Rapper Appears: The album version of the ending theme.
- Willing Suspension of Disbelief: In the anime, since they have 5 characters to go through in 24 episodes which sums up around 3-5 episodes per girl, post deduction of the exposition; that means the plot for each arc / route has to advance quickly; which enforces Ass Pull characters or motives to appear without any explanation or proper legitimization to advance the plot. But the viewer is willing to avert one's gaze away specifically because of the limited number of episodes. The prime example of this would be the fact the protagonist goes one love interest after the other in such a short time.
- World-Healing Wave: In the anime adaptations of Kanon, Ayu disappears as an astral projection through the granting of a wish that improves everyone else's lives.
Kanon Another Story: Wonder Three provides examples of:
- Adaptation Dye-Job: Kaori's hair is now orange.
- Ascended Extra: Jun Kitagawa is one of the most prominent characters in the manga.
- Beta Couple: Not Kitagawa and Kaori, but Kitagawa and Shiori.
- BFS: Mai's sword.
- Big Brother Attraction: Ayu calls Yuuichi "oniichan", despite their being the same age. This appears to be to shock readers used to an Ayu ending in every adaptation into realizing that, hey, this ain't the Kanon they're used to.
- Bland-Name Product: "McBonald's".
- Byronic Hero: This version's Yuuichi barely has any good points.
- Demoted to Extra: Makoto gets one mention. That's it.
- Establishing Character Moment: Everyone whose personality is markedly different gets one. Yuuichi starts a snark war with Nayuki that goes far past any other Yuuichi's limits to how rude he can be, and Nayuki is just as rude back. And Shiori? Shiori wraps a rock in her shawl, tosses it at Yuuichi and Kitagawa, and blames it on the wind.
- For Want of a Nail: What if Yuuichi remembered Ayu right away?
- I Have No Younger Sister: In this version, Nayuki actually knows from the start that Kaori and Shiori are sisters and says so even when Kaori's denying it to her face, which makes the relationship dynamics somewhat more messed up than usual.
- Love Triangle: Nayuki insinuates that a Type 4 is going on between Sayuri, Mai, and Yuuichi. Whether Sayuri actually does love Mai is up for debate, but the mangaka probably knew the pairing's popularity.
- Off Model: Say what you want about Key's own art style, but this takes getting used to.
- Promoted to Love Interest: Unlike every other adaptation, instead of picking Ayu or Nayuki, Yuuichi ends up with Mai.
- Rapunzel Hair: Kaori's hair, aside from being a different colour, is now past her hips. She barely looks anything like Shiori.
- Secret Keeper: Akiko, as usual, but she's more overt about it here.
- Sickly Neurotic Geek: Shiori. Car fanatic, technological wizard, and might not even really be terminally ill in this version.
- Snark Knight: Nayuki, of all people.
- Spoiled Sweet: Shiori; she even acts up-front about her illness instead of hiding it because she's used to people treating her better if they know she's dying, but she's still one of the nicest people around. (Okay, in a manga where Minase Nayuki is a complete jerk, "nicest" is relative...)
