The protagonist of the series. Due to his habit of always arriving late to school, skipping classes during the day, and staying out all night, he has been labeled as a delinquent, or a young person who defies authority. Nevertheless, his actions end up changing everyone else's life for the better.
Chess Master: Repeatedly shows himself adept at being able to manipulate people when the need arises and has shown via inner monologues to be quite intuitive about how the world and people work. This is only limited by the fact that he's technically Book Dumb and also a Nice Guy underneath the delinquent exterior. God help us all if he wasn't either of these things.
Cool Loser: The anime seems conflicted as to how much it wants him to fit the trope. For whatever reason, he's an astounding Chick Magnet, and for whatever reason, he seems to have an enormously positive impact on every girl he befriends. Nevertheless, people keep calling him a loser — especially in the Tomoyo ArcAlternate Universe.
It's less that he's "uncool" so much that he's a delinquent constantly on the verge of failing high school (through lack of effort, not lack of intelligence). The other students have a low opinion of him because he's getting set up to waste his life. He does end up getting a respectable, albeit rather low-income, job in both endings that touch on his post-high school life.
Double Meaning: After breaking up with Tomoyo he begins talking to Sunohara while rather depressed. Sunohara says something to the effect of "Man, I expected her to pick you over the cherry trees" and Tomoya agrees. That's why he took the decision out of her hands.
Everyone Has Standards: Given his penchant for playing jokes on his friends, he feels guilty about dropping the toy giant bengal lizard down Sanae's back.
Faux Yay: Okazaki's intent when he tells Nagisa that Youhei Sunohara has a crush on him to obscure the real reason Sunohara is throwing himself into a basketball-related Zany Scheme.
Felony Misdemeanor: His classmates see him as a delinquent, but all he does is cut class and show up late.
Friend or Idol Decision: A very low key one occurs in Tomoyo's route. If he lets her continue on without help, she'll lose the Student Council President election like he wantsnote He's made it clear to everyone that he doesn't like the Student Council and wants nothing to do with it, but that would obviously hurt her even if she wouldn't blame him. He chooses to assist, picking friend. Later, he tries to do it again and breaks up with her and gets rid of his own happiness to do what he thinks is best for her, but this time she doesn't accept it and at the end they get back together.
Friendzone: He worries that he's managed to put himself here in Yukine's route since she begins to treat him like she did her older brother.
The Gadfly: Tomoya likes to pull pranks on people, especially Sunohara.
Generation Xerox: As much as Tomoya hates his father for neglecting him to dull the pain of his mother's death, he does exactly the same to his own daughter Ushio in his attempt to forget that her birth killed Nagisa.
As a bonus, Tomoya looks almost exactly like the younger version of his father, just without the glasses.
Subverted almost immediately after, when Tomoya takes Ushio to the countryside and meets his grandmother, who has some revelations in store for him about his father.
Genre Savvy: If you choose not to escort Ryou home, Kyou attacks Tomoya who points out quite correctly that the way Kyou is trying to force them together just isn't going to work and will cause people a lot of pain.
Heroes Want Redheads: Or whatever color Nagisa's hair is. Let's go with "red". Note that the other major character with let's-call-it-red hair is Sanae, Nagisa's mother — who just happens to be the only character in the entire series who can really bring out Nagisa's Clingy Jealous Girl side.
Heroic BSOD: After Nagisa's death, Tomoya falls into such a deep and long-lasting depression that he essentially ignores his own daughter — for five years. Fortunately, Akio and especially Sanae were around to pick up the slack — and also to coax Tomoya back to life.
He is not above pulling pranks on those same people he seriously cares about. This could be his way of making them feel comfortable amidst their problems.
In the 2006 movie by Toei, Tomoya is a much bigger jerk than in the reboot by Kyoto Animation. (At least in the beginning of the movie. As the movie goes along, his personality tends to get overwhelmed as the movie struggles to cram as much plot into ninety minutes as it can.)
Love Hurts: Takes up this mentality right after Nagisa's death, thinking he should never have met Nagisa because of the pain her death causes him. Gets over this in the finale and decides meeting and loving Nagisa makes all the pain worth it.
Married to the Job: He promises to attend the founder's festival with Nagisa in ~After Story~, but he discovers he made a major mistake at one of his jobs at the electric company. Yoshino covers for him and he even tells him to go on to the festival, but Tomoya helps him anyway. This prevents Tomoya for showing up until it's over, but Nagisa understands.
No Good Deed Goes Unpunished: His earnest efforts to help others are usually overridden by the fact that the public sees him as a no-good delinquent. And in Tomoyo After, his efforts to build a school results in him suffering a blow to the head which causes amnesia and a failed surgery leading to death three years after.
Oblivious to Love: Frequently, though he'll usually catch on to his love interest for the route and begin doing something about it.
Panicky Expectant Father: A justified example, given Nagisa's health and subsequent death giving birth to Ushio in the bad ending.
Parental Neglect: Tomoya's father neglects him to forget the pain of losing his wife. Unfortunately, like father like son.
Selective Obliviousness: Only applies to the anime. In the game he can only solve one girl's route during a single continuity and and is, for the most part, not oblivious to their affections. Most importantly though, in the game Nagisa isn't with him for just about everything.
Soap Opera Disease: In Tomoyo After, after helping a village in building a school and giving the people hope to live again. And he dies from it in the True End.
Stepford Smiler: The casual behavior might fool the watcher/reader for awhile, but it becomes clear over time that he's basically starting the story in despair.
Tomoya's very emotionally troubled father. They had a falling out when Tomoya was in middle school, when he dislocated Tomoya's right shoulder. To stave off depression, he turned to heavy drinking (daily) and harder drugs (less daily).
Early-Bird Cameo: She's the girl running through the field with yellow flowers in the first season's opening, and it's her legs you see skipping in the second season's ending. Also appears twice, with her face hidden, in the second season opening; once talked to by Kyou, once hugged by Fuko.
Nagisa is the main heroine of CLANNAD. A shy girl lacking in confidence, she meets Tomoya when she pauses (amid a sea of Cherry Blossoms) at the bottom of the hill, struggling to bring herself to continue on her way to school. Tomoya gives her some encouragement and eventually assists her in her dream of reestablishing the Drama Club.In the anime, and in her route in the visual novel, she later becomes Tomoya's wife and mother to Ushio.
First Girl Wins: Especially in the anime, although the game leans that way as well. But taking Tomoya's childhood into account, it's actually subverted (the first girl would then be Kotomi, not to mention that Nagisa is the third girl he met after Kyou). She's pretty easy to pick out as being the main heroine with After Story and all.
Nice Girl: She's easily one of the nicest character, matched only by the likes of Yukine. She's even nice to Sunohara!
Not So Weak: She won't let even Sunohara go undefended.
Official Couple: Nagisa and Tomoya's first meeting is quite the important event in the anime and a much bigger deal of it is made than in the VN. However, don't be fooled into thinking she's only the primary heroine due to adaptation: The entire second half of the story follows her ending.
Older Than She Looks: Mild example... for now. Her look and childish demeanor makes her seem like the youngest of the group, when in fact she is the oldest, having had to repeat her senior year. Twice. She is one year older than Tomoya, Kyou, Ryou, Kotomi and Sunohara, two years older than Tomoyo and Yukine. Of course, considering who her parents are, there's a very good chance she'll fully belong in this trope when she gets older.
Really Dead Montage: Although ultimately subverted, the use of this trope in the anime and the finality it implies really sell the moment as the monumental Tear Jerker it's meant to be.
Verbal Tic: She has a habit of ending sentences with "-desu".
Yamato Nadeshiko: Nagisa evolves into this in After Story. The biggest proof is how she gives Tomoya a Cooldown Hug when he's under the effects of a massive Heroic BSOD. This sickly and shy girl manages to pin her much healthier, taller and physically stronger boyfriend to a wall so he won't hurt himself further.
Nagisa's mother, an ex-teacher who runs a bakery alongside her husband, Akio. Sanae is always trying to make new bread with unique properties (i.e. bread with rice crackers inside) although almost none of them turn out to be successful. She is very sensitive and cries easily especially when she is told her bread tastes bad.
All Loving Heroine: Even by the standards of this series, Sanae manages to stand out. This becomes more and more evident as Tomoya sinks deeper and deeper into gloom in the middle third of ~After Story~. See also Manic Pixie Dream Girl.
Note that it's only her bread that's terrible. Every other dish she cooks is apparently delicious.
First Name Basis: Generally, she's very formal. But her granddaughter calls her Sanae (well, Sanae-san).
Friend to All Children: True to her Yamato Nadeshiko status, she's very friendly and motherly to the kids she teaches at her cram school. She also helps a couple of lost children when on her "date" with Youhei.
Let Her Grow Up, Dear: Akio is torn between denial, happiness at becoming a grandfather, and wanting to strangle Tomoya when he finds out that his married daughter is pregnant. Sanae, however, is delighted.
Manic Pixie Dream Girl: The series plays with this trope, in a (mostly) non-romantic way. Not all that much in season one; far more in ~After Story~. Perhaps most intensely — and most cleverly — pulled off in the first half of episode 17, when a quasi-flirtatious Sanae attempts to coax a brutally depressed Tomoya out of his five-year-long Heroic BSOD. She play-acts the Manic Pixie Dream Girl role to perfection here. But in episode 18, through Ushio's comments, we see a more damaged side to Sanae, and at the beginning of episode 19, the facade shatters as Sanae finally lets down her guard and allows herself to cry in Akio's arms and mourn for her daughter Nagisa. She's no longer any sort of Manic Pixie Dream Girl; she's just a deeply loving and truly anguished mother.
Running Gag: Someone (usually Akio) insults her bread, with her standing right behind him. She'll get upset, muttering "My bread, my bread..." and run out crying, and the offender will run out after her with a whole bunch of bread stuffed in his mouth, screaming about how he actually loves it.
Stepford Smiler: She keeps a cheerful exterior, even after her daughter's death, as seen below.
Unable to Cry: It's not that she's unable to cry after Nagisa's death, but that Ushio needs her strength after having to look after her. The scene where she finally does cry for her dead daughter, five years after the fact, is truly heartwrenching.
Nagisa's dad. Although he often talks and plays rough, he is kind and sympathetic. His childish side makes it easy for people to befriend him. He used to be an actor, now runs the Furukawa Bakery with his wife Sanae. In his spare time, Akio plays baseball with children in the small park next to the bakery, and indulges in the Gundam fandom.
Crazy Jealous Guy: Chased Youhei with a baseball bat for being in love with his wife, Sanae
Large Ham: Well, he was an actor before becoming a baker.
Lovable Sex Maniac: (VN) He may be exaggerating this part of his personality somewhat in order to see Tomoya's reaction, but Akio does have a porn collection Sanae doesn't know about, and encourages Tomoya to have sex with Nagisa before they're married. Yeah...
Older Than He Looks: Shares this with his wife, Sanae. He looks like a handsome thirty — possibly even younger — but given that his daughter Nagisa is eighteen or nineteen at the beginning of the series, that's hardly likely.
Overprotective Dad: Played mostly for comedy. Just over halfway through ~After Story~, upon finding out that his daughter Nagisa is pregnant, Akio is torn between denial — "A stork brought it. Right?" — joy at becoming a grandfather, and desire to strangle Tomoya for sleeping with his innocent little girl — "You bastard! (manages to contort his grimace into a sort of smile) Congratulations!" (Worth noting: this scene represents rather extreme Selective Obliviousness, as it takes place several months after Tomoya and Nagisa have gotten married.)
Papa Wolf: When the creeps in the family restaurant Nagisa works at try to make a move on her, he and Tomoya show them why it's a bad idea.
Paper-Thin Disguise: Definitely. Although not quite as paper thin (nor as successful) as his wife Sanae's disguise.
Class Representative of 3-E, Kyou has known both Tomoya and Sunohara since their junior year. As she is known for being overprotective of both Botan and her sister Ryou, she is known for literally throwing the book at Tomoya and Sunohara. She proved to be a very popular character in the anime, resulting in a spinoff episode that showed what would have happened if Tomoya had chosen her route instead of Nagisa's.
Class Representative: Her junior year and again her senior year. Not just a literal example, but also fits the temperament for the trope.
Clingy Jealous Girl: She gets a little upset when Tomoya interacts more with other girls. In Tomoyo's route, she's clearly thinking something like 'Why did you pick her when I'm not that different' before picking a fight with her. Tomoyo's indirect answer boils down to "It's because I didn't get too scared to make a move."
Cool Big Sis: To Ryou. Though as they're twins, it's not obvious which of them is "older," but Kyou certainly fulfills the archetype. She also plays this role to Kotomi after befriending her.
Covert Pervert: A couple examples, but we don't get to see what she was thinking. One where Kyou is trying to think of why Ryou is embarrassed and immediately concluding they must have done something inappropriate in public. A second example is her blush and disappointment that Tomoya didn't enter the laser tag game in Kappei's route. The winner would get to order the other to do whatever they wanted for a week.
Friendzone: It would be a Childhood Friend Romance had she known Tomoya before their junior year. If you make one of the wrong decisions in the VN, Tomoya will express depression at how his relationship with her hadn't changed since he had known her, indicating that despite her fears of rejection he was never averse to the idea.
Genki Girl: Probably the purest example in the franchise.
Hot Teacher: In After Story, she works as a Kindergarten teacher and teaches Nagisa and Tomoya's child Ushio.
Important Hair Cut: At the end of her arc, she cuts her hair short, like Ryou's, as part of a desperate attempt to be more like Ryou.
I Want My Beloved to Be Happy: In the anime, once Kyou finally admits to herself that she and Ryou have both lost any hope of winning Tomoya's heart she goes back to normal after a good cry and remains friends not just with Tomoya but with Nagisa. In her route, she has this attitude towards her sister, though that's also because she doesn't have the nerve to make a move herself.
Stepford Smiler: Made abundantly clear in the visual novel (less so in the anime), whenever Kyou is talking about how Tomoya needs to pay attention to Ryou more she's crying inside.
Team Mom: Sometimes, especially in episode 10 and 11.
Throw the Book at Them: Her Weapon of Choice is a dictionary. Usually aimed at Youhei, but sometimes at Tomoya, especially when she thinks (or pretends to think) he's plotting to eat her pet baby boar Botan. (See Team Pet, above.) (She usually hits Youhei, whereas she usually misses Tomoya. Presumably this is at least in part intentional on Kyou's part.)
Triang Relations: Type 13 with Kyou at A, Ryou at B and Tomoya at C. It gets complicated from there because while the basics are simple (Kyou and Ryou like Tomoya, who is friends with one and barely knows the other and Kyou is supporting Ryou) new factors enter the equation when Tomoya begins dating Ryou on the theory that he might come to like her eventually, but ends up liking Kyou.
Tsundere: A particularly agressive Type B, she still favours a friendly personality over a confrontational one. She is very quick to switch to tsun-tsun mode, though. She mellows out considerably in ~After Story~, when she's revealed to be Ushio's kindergarten teacher.
The younger and more timid of the Fujibayashi twins. Is the class representative of her room, but only won it through lottery rather then through actual voting. Is known for telling fortunes of anyone who asks her. Her fortunes are always complex and usually completely off the mark, though she can be eerily accurate at times. Though she is usually wrong, she believes that it would be better for the future not to be already set. She has a crush on Tomoya in the beginning and enlists Kyou's help, or rather, Kyou insists on helping her. Despite her crush, however, she is not one of the Love Interests Tomoya can pursue in the visual novel.
Cannot Spit It Out: Her feelings toward Tomoya. Even with the abundant help of her twin sister Kyou, she never actually manages to make a confession in the anime. She does manage in an Alternate Universe OVA based off of her VN route, where it's also clear to Tomoya.
Cleaning Up Romantic Loose Ends: The Kyou epilogue notes that she started dating someone she met at the hospital who has a cute face, meaning that she likely hooked up with Kappei.
Cloudcuckoolander: A mild example, especially compared with certain other characters in the series.
Demoted to Extra: She's not an official haremette, and picking her over Kyou in the Visual Novel is a Bad End in terms of progression, since you don't obtain a Light Orb. It's not a bad bad end, it's just that you haven't really completed the story since it's really Kyou's route.
I Want My Beloved to Be Happy: At least in the anime series. Not that she ever really seems to hold much hope for winning Tomoya's heart; she often seems to be going through the motions in order to appease her more forceful sister. In the Kyou route she gives up and sets up Tomoya and Kyou when it becomes obvious she can't hold on to him..
Lethal Chef: Her cooking is considered completely inedible. In Kyou's route, while Ryou starts out a horrible chef she does her best to get better so that she can be more like Kyou, whom Tomoya likes more. She gets close enough to her sister in skill that Tomoya is very much reminded of Kyou — but she never quite matches her.
Otaku: Surprisingly enough. Heavily implied in the VN when Kotomi is messing around with the Magical girl wand. She states that she has a really high interest in these kinds of things.
Polar Opposite Twins: With her twin sister Kyou. She's quiet and shy while Kyou is loud and aggressive, though it turns out both suck at talking to the guy they like.
Stepford Smiler: Realizes perfectly well that Kyou and Tomoya have a lot more chemistry and mutual attraction, but hides it. Then she tries to act as much like Kyou as she can, but can't quite do it as seen with the pork cutlets.
Kotomi is a strange girl: she has No Social Skills and is fearful and asocial. Generally she is silent. She squirrels herself away in the school library — she is always kneeling on the library floor, reading. Absorbingseveral pages of abstruse text per minute. Kotomi also likes to go barefoot in the library like it's her own home, almost instinctively removing her shoes and socks during her visits there. However, her footwear-doffing compulsion sometimes extends beyond the walls of the library- along with the urge to snip pages from books with scissors.When Tomoya meets her, he manages to cut through some of her protective layers and socialize with her a bit, but each time he attempts to start up a conversation with her she won't notice him and respond unless he remembers to call her 'Kotomi-chan'. She has a habit of cutting pages from books and newspapers. The polar opposite of Book Dumb, she is among the highest test scorers her year in all of Japan, and her classmates revere from afar as a genius. She has a deep-seated fear of bullies and a mysterious man in a black suit.As it turns out, Kotomi was Tomoya's childhood friend. He has forgotten her, although she has not forgotten him. Her parents, important academics, were always too busy to attend her birthday when she was a child. Before one fateful birthday, they made a promise to attend and give her a teddy bear, but they died in a plane crash before that could happen. The mysterious man in black is actually a friend of her father's, the one who informed her of her parents' death — an association that causes her fear of him years later.Kotomi was too devastated to hear of their death and the prospect of them forgetting her by dying like that without her present and eventually she burnt a catalogue that she thought to be her father's scientific paper (which turns out to be a catalogue for the teddy bear they'd bought her), which started a fire that would likely have burnt down her house, with her in it, were it not for the quick action of that man in black. (Tomoya was there, too, although he forgets about it until near the end of the first season.)After the fire, Kotomi vows to study hard and make amends for her destruction of (what she thinks was) this seminal scientific work, by becoming an important intellectual in her own right. Socializing simply isn't important to her — at least until she meets Tomoya again, when they're high school seniors.Tomoya befriends her and helps her to open up and socialize. Later she discovers that her parents never forgot about her, and the last thing they preserved before their death was Kotomi's present, a teddy bear doll. After this, in the Visual Novel, Kotomi resumes her relationship with Tomoya as his girlfriend. But in the anime, she gets Demoted to Extra.
Animal Motifs: Possibly. Butterflies were more common in her arc than anywhere else.
The Atoner: Her guilt over (seemingly) burning her parents' research paper, as well as her Survivor Guilt in general, drives her to devote her life to studying so that she can replicate their theories.
Chekhov's Gunman: Her and her parents' theory of multiple universes becomes important to the true ending.
Cloudcuckoolander: When we first meet her, she's so much in her own dream-world that she doesn't even notice other people trying to talk to her — unless that person is Tomoya and he remembers to address her as Kotomi-chan. She gets better — somewhat — with a lot of help from Tomoya and the gang.
Dreadful Musician: When playing her violin, she can level an entire wing of the school. Interestingly, she's depicted as holding the violin and the bow in the manner of a skilled violinist (something that takes most violinists years and years to accomplish), and in the flashbacks to her childhood, her playing does not seem to cause any particular problems. So maybe she sounds so terrible because she's very out of practice. Nagisa also claims that her violin playing has improved during her practice, but sounds awful during her recital. Stage fright, perhaps?
Heroic BSOD: Experiences a serious one when she thinks Ryou was involved in a bus accident. It lasts at least a week, and several episodes/until almost the end of the route. It's because she's reminded of her parents' death.
Meaningful Name: She is named after the Japanese stringed instrument, the Koto. This is meaningful in two ways, one serious, one ironic. Serious: Her father named her that out of his belief that the world made up of millions of kotos, and when they combined their music together, do great things. Replace koto with person in that idea, and you get the main theme of Clannad, that individuals who come together to form a group; a family, a nakama or a commmunity; do things greater than the sum of their parts. And the ironic part? That a girl named after a stringed musical instrument would be so bad in playing another stringed musical instrument.
Actually, she is named after both her parents: Ko(utarou) + to(="and") + Mi(zue). "Kotomi" is Japanese for "K&M". As her mother said, the most important things are always simple.
Her name is also a reference to string theory in physics.
Supreme Chef: She's also a good cook, as evidenced by her apple pie.
Surprisingly Good English: Though she isn't seen speaking it, she can speed-read complex scientific English textbooks that would make most native speakers' brains melt. She also gets a scholarship to study in America.
Verbal Tic: She has a habit of ending her sentences with "-no".
Vocal Evolution: When we first meet her, she speaks in a quiet almost-whisper. As she befriends the rest of the gang, she speaks in a more confident, albeit still quiet, tone.
The Wonka: Despite her eccentricities, she is by far the most intelligent person in the school. Possibly the smartest high school student in Japan.
Yamato Nadeshiko: She seems to be evolving into one after coming out of her shell. For example, she shows up to the New Year's party in ~After Story~, in a kimono, the only girl to do so in the scene. Her cooking ability and her natural meekness would also make her qualify.
A beautifuldelinquent who has attained legendary status as a fighter. Tomoyo at first is a rough, cold-hearted girl who delivers the frustration of her messed up family that almost considered divorcing by fighting and hurting other people. That changed when her little brother Takafumi, in a desperate attempt to fix things up, either threw himself to the river or gets himself into a car crash, ending up crippled and instantly mending the family and softens up Tomoyo. She later hears her brother's wish to see the sakura tree, and made it her mission to preserve those trees. She later attends at Tomoya's school and starts out by driving out some delinquents that threaten the school, and later spends her time not only to become the Student Council President (the only position where she can issue orders to preserve the sakura tree), also kicking Sunohara's butt whenever he pisses her off (and repeatedly). After much hardships of winning the students' hearts and cleans up her delinquent status, she is elected as the Student Council President, and continues to be friends with the ones who help her doing so: Tomoya.Tomoyo proves to be wildly popular that she later gets selected as the protagonist of a special sequel which is the continuation of her visual novel story. Her route also gets animated in an Alternate Universe episode based on her Visual Novel route, whereas she dates Tomoya (whereas other girls don't seem to exist), but both became torn between their status and decided to move on to their own path, breaking up in result. When Tomoya finally graduates, Tomoyo waits for him and they tearfully reunite as lovers.
Action Girl: If she had to, she'd kick Buffy's ass. She'd apologize afterward, of course. But she'd do it, and you damn well know it.
Boobs of Steel: Only second to Kotomi in bust size, and a fearsome brawler.
Breaking the Fourth Wall: In the visual novel when she kicks Sunohara, an image of him falling will pop up on the screen, and sometimes stay there while waiting for the reader to click. In one scene, she tells him to hurry and up and fall, because he's blocking the whole screen.
Breakout Character: With the spinoff Tomoyo After. She also received a genuine adaptation of her route in the form of an OVA.
Covert Pervert: (Visual Novel) Indirectly, as when Tomoya turns to dirty thoughts about Tomoyo, she's glad that he's able to think of her that way. And with a little needling, she'll freak and realize that she's thinking of the same things.
Dark and Troubled Past: Her past as a delinquent, her parents' marital problems and her brother's attempted suicide.
Defrosting Ice Queen: By her own admission. She was a coldhearted delinquent who lashed out at others to deal with the stress of her home like until her brother's incident. Now she's one of the nicest people in the show.
Shares a lot of similarities to Madoka Ayukawa. Both of them are moe, cold, extremely talented, intelligent, tsundere, reformed delinquents with feminine sides and romantic attachments to losers.
Femininity Failure: She often tries to make herself look more feminine and gets worried when she thinks she's not being seen as a girl. While her results are rather lacking from Tomoya's point of view, he finds the attempts pretty funny. He makes it pretty clear that he doesn't expect her to be a girly girl anyway. It tends to get lost on anglophone fans, but her speech patterns are also coarse and masculine (reflecting her past as a delinquent), contrasting heavily with her image.
Meganekko: By the end of the first season, and especially in the Alternate UniverseTomoyo Arcomake episode, in which she's not just the female romantic lead, but the only female character of significance.
Teen Genius: At least in her Alternate Universe arc, in which she scores fourth in her year for all of Japan on her exams. Note that this is less than a year after she decided to clean up her image, after being something of a borderline delinquent for the previous few years.
Tomboy: She has fairly masculine and blunt grammar patterns, enjoys the life of a delinquent and seems to find her more girly friends slightly boring at times. When she starts becoming attracted to Tomoya, she makes a rather lacking attempt to make herself seem more girly.
Vitriolic Best Buds: Despite his escapades and stupidity, she´s actually pretty good friends with Sunohara.
What Does She See in Him?: A lot of people seem unclear as to why she's interested in Tomoya. A teacher is the one who says it most clearly.
Tomoyo's little brother, Takafumi was the one who brought Tomoyo out her "delinquent" phase. Sometime in the past, the Sakagami family was in ruins because of their father's affair. In order to bring the family back together, Takafumi tries to drown himself (in the anime) or throws himself in front of a moving car (in the original materials). Predictably, this helps stop the family feud and Tomoyo begins to change her old ways, but this leaves Takafumi temporarily crippled.His role and backstory is expanded in the Gaiden GameTomoyo After, as a freeloader in Tomoya's apartment where Takafumi's sister frequents. It is revealed here that before his "accident", Takafumi was the ace of their track team. He had deeply admired his coach, who had a daughter named Kanako. Takafumi and Kanako fell in love and became a couple — however, Takafumi betrayed his coach (who had high hopes for the boy's talent) by willingly throwing himself into an accident and ultimately crippling himself in the process. This leaves the coach distraught and the couple estranged. At the present, Takafumi is presented as a Lazy BumGadgeteer Genius who freeloads at Tomoya's apartment and usually ends up roped into the occasional Zany Scheme. Oh, and then his ex Kanako returns to town.
Satellite Character: Being a minor character, his entire personality is basically summed up as "the kid who changed Tomoyo from a delinquent to a model student" in Clannad. Tomoyo After corrects this by giving Takafumi an extension to his role and backstory.
A rather strange, short girl, who never seems to take classes and is often to be found sitting somewhere quiet carving wooden star shapes. A rumor about her being a ghost is floating about the school, and she has a tendency to force her carvings on any student she meets, requesting that in return they attend her elder sister's wedding and congratulate her.In reality, Fuko is somehow projecting herself into the school from her comatose body, having been unconscious since she was hit by a car after her first day at the school. As the end of her storyline looms, everyone begins to forget about her, losing the ability to see or interact with her, until a last, massive effort allows her to reappear for a brief moment, and congratulate her elder sister herself. Not long beforehand, her sister had revealed to Tomoya that Fuko's body in the hospital had "stopped breathing".In the anime, Kouko meant that Fuko had a low chance of waking up, as her condition had deteriorated. But this has been officially Jossed as of the Grand Finale, where after Tomoya initiates the Reset Button Ending and saves the lives of both Ushio and Nagisa, a light orb is obtained by Fuko and as a result, she wakes up from her coma.
Animal Motifs: Fuko's mannerisms are rather doglike. When they first meet, Tomoya has her give him her "paw" like a dog. At the very end, she locates Ushio from the Illusionary World using her sense of smell, like a bloodhound. There's also her starfish obsession.
Cuteness Overload: Periodically goes into lapses of this when exposed to starfish and Ushio, prompting Tomoya to squirt fruit juice up her nose to snap her out of it and also because it's funny.
Drop-In Character: In the anime, after her arc, she magically reappears in short cameos here and there to foreshadow what will happen at the end of the series, and the main page of this show explains that it's also All There in the Manual.
An art teacher until Nagisa's first senior year. She retired afterwards, and got married to Yuusuke Yoshino.
Chekhov's Gunman: Her first appearance, when she walks into the bakery, has a generic character feel. It isn't until two episodes later, when Toyoma runs into her again, where we realize that brief scene introduced an important character.
Informed Attractiveness: She's very pretty, but since she's in a series utterly flooded with exceptionally moe characters, it seems odd when Tomoya (in his guise as the show's narrator) tells us how beautiful she is.
Messianic Archetype: Has a lot of elements of this, especially in the eyes of (some of) the characters. (A notable exception is Misae, who dislikes him and can't stand the attention he draws.) Nearly always played for laughs rather than drama.
Tomoya's best buddy and fellow delinquent. Generally a dim but lovable fellow. Makes for a great punching bag. Well, it tends to be kicks, really.
Armor-Piercing Question: In the middle of a comedic scene in the middle of Fujibayashi sister's route, Sunohara pulls out this question and kills off not only the conversation, but also the BGM. The answer, of course, is 'no.' Or to be more accurate 'No, and I've been trying not to think about that.'
"So, you like [Ryou]?" Beat "I'm asking if you like Fujibayashi Ryou, since, well, you're going out with her right?"
Big Brother Instinct: Do NOT wrong poor little Mei. Though since he genuinely trusts Tomoya, his attempts to press this button fail to the point that he ends up thinking Sunohara doesn't care.
Boke and Tsukkomi Routine: This is his whole life. Or maybe it's more of a Butt Monkey-And-Tsukkomi-Routine. Either way, he continually says or does something stupid, and Tomoya, Kyou, Tomoyo, or some other character is on hand to hit him (or worse).
Casting Gag: Greg Ayres previously played Kanon's Butt Monkey, Jun Kitagawa. This makes for one hell of an amusing Brick Joke in After Story if you remember what Kitagawa said about wanting to try Akiko's jam.
Honorary Uncle: Tomoya refers to him as "Uncle Youhei" in the last OVA episode summing up the entire series.
Iron Butt Monkey: It is quite a wonder how he could take over the top physical abuses (Mostly by Kyou, Tomoyo, Misae, and Akio) and walk away like nothing happened when you would expected him to be carried away on a stretcher. He shouldn't be alive, actually considering that the rest of the cast is much more fragile. When they played baseball against another town, Tomoya made him the team's catcher specifically because he's the only one who could endure the sheer power behind Akio's throws.
Jerk Ass: At times. The closest thing the series has, among all the major characters.
Jerk Jock: Used to be one. Now gets beaten up by them.
His on screen beatings are only for comic relief purposes, the only serious one was during a flashback with him quitting the soccer club, aside from all that he's hardly the wimp puching bag, it's quite the contrary back when he and Tomoya weren't such good friends they were actually feared, when they became partners they also became more of a pranksters duo than real delinquents. This change of habits still didn't turn him into a target of other Jocks.
What Happened to the Mouse?: Being the protagonist's best friend wasn't enough for him to play a major role or even appear more than just a few seconds in the later years of After Story, too bad for Tomoya his friend wasn't visible enough to help him face all those family problems.
His only known feature during these harsh times is him working at some kind of a driving company.
Justified in that he moved to Tokyo to work at aforementioned company. He even told Tomoya over the phone that he just doesn't have the time to come out whenever he wants.
Brother-Sister Incest: In one of Tomoya's Imagine Spots. More subtle moments pop up from time to time — not actually suggesting incest between the two, but with people (sometimes even Mei herself) tricking Youhei by saying, for example, that a cute girl has arrived to visit him. Youhei being Youhei, he always falls for it.
Cannot Spit It Out: A Subverted Trope, in that she likely would have no trouble expressing her feelings for the boy in question — except, as it turns out, the boy she likes already has a girlfriend, and he goes out of his way to cut off Misae's potential Love Confessions. The boy does this to spare Misae potential embarrassment — or at least, that's how he and his girlfriend choose to view his actions. Misae's friends have less generous opinions of his behavior.
Class Representative: During the flashback to her high school days. Maybe or maybe not, in the literal sense — although she does become Student Council President, which suggests a bit of background and interest in student politics. But she definitely has the temperament.
Cool Big Sis: She's awesome, especially when dealing with the troublemakers under her supervision in the boys' dorm, including not only the Rugby Club and but also Sunohara.
Cute Little Fangs: Sometimes when she's angry, but also sometimes when playing happily with her cat.
Thought it would be worth mentioning this. In Full Metal Panic? Fumoffu, Chidori does a Japanese Ocean Cyclone Suplex Hold on Sousuke in episode two. Misae does a toned-down version in in episode 5 of Clannad After Story.
Hair Decorations: In the flashbacks to her high school days, she wears a ribbon that looks almost like cat ears. Which is completely appropriate, given who she winds up with at the festival. (Worth noting: that same basic ribbon, with those same implied cat ears, turns up on several other girls over the course of the series. But it never looks as thoroughly catlike as it does on her.)
Interspecies Romance: With "Katsuki Shima", who she met and fell in love with in her freshman year. Yeah, apparently he forgot he was a cat that turned into a human to grant his dying master's wish. Woops!
Second Love: In her mini route, Shima was this for her after a crush. If you don't believe the crush was really love, which is supported by the story, then her second love is instead Tomoya after he convinces her she can't just keep waiting for someone to come back when it's clear he isn't going to.
Tsundere: Very much so, in temperament — even though for the vast majority of the series she doesn't have any potential Love Interests with whom to play this tango. Unless you count her "Katsuki Shima". Which you won't, until you reach her high school flashback.
Wrestler in All of Us: Tomoya advises her to use pro wrestling moves to punish the boys she oversees in the dorm, and she often demonstrates them on the unfortunate Sunohara. Eventually, a flashback reveals that she's been using these moves since her high school days.
Yukine is a second year student who hangs around in the library's reference room. The anime gives her out of school life an action packed Adaptation Expansion, replacing the reference room romance that makes up her visual novel route.
Half Truth: Yukine being the unofficial librarian of the reference room. She's actually there because the reference room is secluded and easy to sneak into from outside the school, thus her friends won't get into any trouble.
Idiot Hair: Quite distinctive. Which seems odd, since she's a kindly Book Worm who's also socially savvy and quite possibly the leastCloudcuckoolander-ish character we meet in the entire franchise. (That said, she does often get a slightly dopey blank look on her face when she's thinking.)
Just Friends: In the Yukine route in the VN, Tomoya worries that he might have friendzoned himself by becoming Yukine's brother surrogate.
He decides to cut that possibility off by kissing her at the end of her route, at great personal risk to himself (as her brother's gang were all there.) A short LN story set after the end of her route shows that they've decided to go steady.
Love Potion: She is fond of love spells, using them liberally as friendship charms.
Teen Genius: We don't know much about her academic abilities, but she's a Book Worm; she's entrusted with the maintainance of the school's second library (the main library being the provinence of indisputable Teen Genius Kotomi); she's skilled enough at healing to be to the go-to-"doctor" for both the rival gangs in town; she's able to broker truces between said groups without outside assistance (most of the time); and she's in some ways the wisest character in the whole series, especially when it comes to relationships. All at age sixteen.
Through His Stomach: After Tomoya randomly ordered omelette rice during their first meeting, Yukine brings the ingredients every single day just in case he ever asked for it again.
A young man who is traveling around. His goal in life is to "live like a man."
Brother Chuck: He doesn't appear at all in the anime, not even in ~After Story~, which spends the first third of the season to go into the side character stories. He does show up very briefly in the last episode's "Where Are They Now?" Epilogue, and someone who might be him appears in the After Story credits, walking in front of Tomoyo.
Cloudcuckoolander: He dramatizes the act of delivering pizza into being a life-saving career, and falls into a daze when describing graphically violent folk tales.
Dude Looks Like a Lady: Confused the hell out of Tomoya for quite awhile, which wasn't helped by his rather strange name. Sunohara refused to accept it at all.
Littlest Cancer Patient: Used to be one at an orphanage until a musician he idolized (implied to be Yuusuke) inspired him to pursue his dreams.
Salaryman: He goes about traveling to find a job — until he settles down in Hikarizaka, mainly because he meets Ryou.
Tragic Dream: Wanted to become a track athlete but has leg cancer. He refuses to let go of his dream, even when the disease becomes life-threatening and there are no options other than amputation of his leg.
She is actually Ushio Okazaki after her death, having lost her memories of her brief life with her father Tomoya. She regains them as she dies in the Illusionary World and she releases the light orbs for Tomoya to use so that he could save Nagisa, herself, and himself from their cursed fate.This is Lampshaded by the first season's Spoiler Opening, with the appearance of the doll, Ushio, and Fuko standing over her which is actually shown in the Grand Finale of After Story in the ending minutes.
The doll is actually Tomoya Okazaki after his death, and after losing his memories of his life. When his daughter Ushio — his sole reason for going to the Illusionary World — dies there, he returns to the real world, having released the light orbs. The light orbs allow him to initiate a Time Skip wherein Nagisa survives giving birth to Ushio. After that, they all live happily ever after.
