Tomoya is the main character of the Clannad visual novel. He is a student at Hikarizaka High School and is referred to as a delinquent who frequently arrives to school late and skips classes, but does not generally start fights. His mother, Atsuko, died in a car crash when he was young and since then has been living with his father, Naoyuki, although they argue constantly. Tomoya's dream of playing professional basketball ended when his father critically injured his shoulder during a fight. He was rushed to the hospital but the wound was declared to be untreatable. Throughout the visual novel, Tomoya is presented with and solves many of his friends' problems. He is a childhood friend of Kotomi Ichinose and is best friends with Youhei Sunohara. At the beginning of the visual novel, Tomoya meets Nagisa Furukawa who becomes his good friend and, later, his girlfriend. In After Story, Tomoya becomes an electrician after graduating from high school. He marries Nagisa and together they have a daughter named Ushio. Aware of her delicate health, Tomoya takes care of Nagisa during her pregnancy, but she dies after giving birth regardless. Tomoya becomes severely depressed and leaves Ushio's care to Akio and Sanae. He spends the next five years of his life in this depressed state, unable to move past Nagisa's death and viewing life as a punishment. Sanae and Akio arrange for the two of them to be left alone at their house, so that Tomoya could be pushed into caring for his daughter again. After interacting with each other, Tomoya realizes that he is putting Ushio through the same pain his father put him through and becomes a better father. After Ushio dies, Tomoya realizes that Ushio is the girl in the Illusionary World. He then uses light orbs to turn back time to the day that Nagisa is in labor and prevents both her and Ushio from dying. In the end, Tomoya lives with his wife and daughter as a peaceful family.
Nagisa is the main heroine. She is shy, sensitive, and uses a non-confrontational style of speech. She shouts the names of food that she plans to eat as a way to motivate herself, such as anpan, a type of sweet bean bread. She admires an outdated group mascot known as the "Dango Daikazoku" (だんご大家族, lit. Big Dango Family) and explains that she likes the fact that they are a close family regardless of the situation. Due to an unspecified illness that lasted nine months, she was forced to repeat her final year so she is a year older than her classmates which causes them to bully or alienate her. Nagisa nearly died as a child due to her parents' preoccupation with their careers since she has periodically suffered long bouts of illness since the age of five. Nagisa's life was spared, however, after her parents abandoned their dreams and opened a bakery to watch over Nagisa's health. Despite having few friends, Nagisa is a caring person. She would not hesitate to assist a stranger. As a result, Tomoya criticizes her at times for being naïve. Nevertheless, she is always kind to him and cares about him a lot. Nagisa's wish of reviving the school's drama club is the priority of Tomoya's efforts, even with the encounters with the other heroines. When Nagisa reaches her goal, she shows a considerable amount of growth since she met Tomoya. The following day, Tomoya confesses his love to her. She accepts it and the two begin their relationship. In After Story, she succumbs to her illness and has to repeat her third-year yet again. She manages to continue attending school every day and dons a brave smile throughout the year. When Tomoya leaves the bakery to move into his own apartment, Nagisa visits him almost every day and cooks meals for him, keeping him company. When winter comes, her illness forces her to be absent at the graduation ceremony. Tomoya organizes a mock graduation ceremony for her. Soon after, she and Tomoya marry. Along with Rie and Sugisaka, Nagisa begins working as a waitress at a family restaurant. Eventually, Nagisa becomes pregnant and she and Tomoya decide to name their child Ushio. Nagisa successfully gives birth to her daughter, Ushio, but dies shortly after childbirth. Both Nagisa and Ushio are eventually saved when Tomoya wishes for a miracle to turn back time. Despite deciding to avoid his first meeting with Nagisa in order to change their fates, he finds he cannot let Nagisa go. By calling out to her again, he proves he does not regret meeting her and the delivery goes well, allowing both Nagisa and Ushio to survive.
Kyou is another heroine of the visual novel and love interest of Tomoya. Kyou is the older of the Fujibayashi twins and is in the same grade as Tomoya, but is in a different class while her sister is in the same class as Tomoya. She is her class representative, but generally does not consider it very important. An exception to this is when she hides the fact that she commutes to school on a scooter because it is prohibited. She is an aggressive girl who can sometimes be overprotective of her sister and is shown to be quite physically strong. Kyou becomes a member of the drama club, although she only signs up so the minimum number of members will be reached. While working so that Ryou and Tomoya become a couple, Kyou falls in love with Tomoya as well. However, after seeing Tomoya helping Nagisa after she got injured, the two sisters hugged and cried as they came to terms with the fact that Tomoya is already in love with Nagisa. Later in After Story, Kyou works as a kindergarten teacher and is also Ushio's teacher. According to Tomoya, her personality is still the same even after the reunion, but Ushio says that Kyou is a good teacher. She misses Nagisa and is often reminded of her each time she sees Ushio. She plays a supporting role in the adaptations. Kyou appears in the movie as a member of the school council and as an assistant to Tomoyo with whom she has a close relationship.
Kotomi is a childhood friend of Tomoya, but, like Kyou, she is in the same year and in a separate class from him. She is a studious girl who is in the top ten for every subject throughout the whole country in standardized exam results. She always goes to the library to read extra materials, especially books in foreign languages. Kotomi is a tacit girl and it is quite difficult to communicate with her. In her spare time, she plays the violin, although she is very poor at it, to the point of causing pain to those who hear her play. Tomoya meets her, but does not remember that they were once good friends until a bus crash causes her to break down in front of everyone. Tomoya visits her in her house and realizes they lost contact with each other after Kotomi's parents died in a plane crash. Not wanting to feel the pain of losing someone important anymore, she asks Tomoya to leave her alone. Wanting to bring Kotomi away from her past, Tomoya decides to renovate her garden while the drama club members decide to gift her a violin, which is unfortunately destroyed. Kotomi confesses to Tomoya that she had been in love with him ever since he entered her life. The next day, her guardian presents Kotomi her parents' briefcase that has traveled all the way to Japan. Inside is a teddy bear and a testimony, asking Kotomi to live the way she wants and grow up to be an adult. Kotomi realizes she is still loved by her parents even after their deaths and cries. After this, Kotomi becomes happy and the drama club members finally give Kotomi another violin for her birthday. In the anime adaptation Clannad After Story, Kotomi moves to America to further her studies about the Illusionary World although she occasionally visits Tomoya and the others. Kotomi also appears in the movie as a background character as she is only seen conducting a song for the members of the choir club.
Tomoyo transferred to Hikarizaka High School as a second-year student during spring. She is a strong silent girl who is known to be intimidating. Although Tomoya is older than she is, she does not show him his due respect as a senior student. She has a younger brother named Takafumi (鷹文). In Tomoyo's path, she is rumored to be violent and to have a record for fighting. These rumors are later confirmed when she beats up several delinquents from her previous school during school hours one day. After several meetings with Tomoyo, Tomoya learns that she wants to be student council president and, later, her reason for wanting to do so: to get enough influence to start a movement to prevent a row of cherry blossom trees from being cut down by development plans. Cherry blossom trees have a special meaning to her since they helped mend her broken family and turned her away from delinquency. When rumors of her former delinquency continue to spread and threaten to derail her campaign, Tomoya helps her out by arranging for her to challenge the various sports teams, all of which she manages to win, thus greatly increasing her popularity. This in turn allows her to win the election. She ends up secretly going out with Tomoya. News of her relationship with him spreads fast and the teachers and fellow student council members try to separate them in the hopes that Tomoyo will concentrate more on her position as student council president and strive to achieve the greater heights they believe she is capable of. Tomoya, worrying about his delinquent status, reluctantly breaks up with her out of fear that he will hold her back. After several months, Tomoyo meets up with Tomoya once again, telling him that she successfully saved the cherry blossom trees from being cut down but lost something in return: her time with him. Tomoya is touched by her words and both decide to resume their relationship. After Tomoya graduates in spring, he sees both Takafumi and Tomoyo off to school with both of them admiring the beauty of the cherry blossoms. In the movie, Tomoyo is also running for student council president, but gets the position much faster and does not interact with Tomoya very much. She is shown to become close with him and his friends and her relationships with Kyou and Youhei are better compared to the visual novel and anime. She and Youhei show up at Tomoya's apartment during his bout of depression after Nagisa's death in an attempt to cheer him up. Tomoyo's story continues in Tomoyo After: It's a Wonderful Life, Key's fifth visual novel and spin-off sequel to Clannad, with her as the main heroine.
Fuko is a first-year student at Hikarizaka High School. She is a mysterious girl who is always alone, making wood carvings of starfish with a small knife to give to others as presents. This hobby occupies her completely to the point that she sometimes loses awareness of her surroundings. Tomoya meets Fuko in an empty classroom, carving a block of wood with a knife. Tomoya confiscates the knife after noticing she is hurting herself, but returns the knife the next day. Some days later, Tomoya learns from Fuko that she is carving seven hundred starfish to be distributed to all the students in the school, wanting them to attend her sister Kouko's wedding. However, no one in school, except for Nagisa, knows about Kouko because she stopped teaching three years ago. After learning about Fuko's current physical state, due to a traffic accident and her existence as an ikiryō or astral projection, both Nagisa and Tomoya decide to help Fuko achieve her dream by giving all the students a carved starfish. As the story progresses, Fuko starts to disappear from everyone's memories due to her waning spiritual power as the real Fuko had stopped breathing in the hospital. Determined to fulfill Fuko's dream and make Kouko's wedding happen, Tomoya asks Mr. Koumura to organize the wedding ceremony on May 18. Through many struggles and hardships, Kouko's wedding is a success, attended by the students who were given a starfish carving. Afterwards, Fuko thanks Tomoya for everything he did and congratulates her sister before disappearing. After the wedding, Kouko and Yusuke decide to thank Fuko in her hospital room. Fuko has a hyperactive and childish personality which, combined with her short stature, causes most people who do not know her to believe that she is a grade schooler. She is judgmental towards Tomoya, often calling him a weird guy, but is secretly dependent on him. Due to this, she has grown to love him and finally shows her feelings by kissing him on the cheek. In After Story, through a miracle from one of Tomoya's light orbs, Fuko recovers from her coma. She becomes incredibly fond of Ushio, claiming that she will kidnap her from Tomoya in order to make Ushio her little sister. Fuko occasionally appears in various unexpected situations. This is actually a nod to the Fuko Ninja event in the game that happens in Tomoyo's path after completing the entire game. In Clannad's epilogue, she is seen coming across the girl in the Illusionary World, who is revealed to be Ushio, sleeping under the tree where Nagisa had been saved from death years earlier, and speaks a cryptic line, hinting at more things to come.
Ushio is Tomoya and Nagisa's daughter and a student at Kyou's kindergarten. She appears prominently in After Story and in the movie. Ushio resembles her mother a lot and likes the Big Dango Family as well. After giving birth to her, Nagisa dies. This deeply saddens Tomoya to the point he gave up raising Ushio and left her to the care of Akio and Sanae. Five years later, Sanae arranges a trip to a flower field for Tomoya and Ushio in the hopes that they will reconcile. During the trip, Tomoya meets his grandmother, Shino, and learns about his father's past and the sacrifices he made for Tomoya which leads him to regret his actions and decide to raise Ushio and acknowledge Naoyuki as his father. Ushio reconciles with her father when she loses a toy robot, the first thing he ever bought for her. Shortly after Tomoya sets things right, Ushio is stricken with the same disease as her mother. Despite the efforts and sacrifices of Tomoya, Akio, and Sanae, Ushio's fever worsens and she spends more time in bed. In the coming Christmas winter, Ushio keeps begging Tomoya to take her on another trip and eventually he agrees. However, on the morning of the trip, she falls unconscious and dies in her father's arms with her dying words being that she loves him. Ushio is then revealed to be the girl in the Illusionary World of her parents' dreams. Desperate to save her family from a cruel fate, she created the world to meet Tomoya again and to collect light orbs to make a miracle possible. If enough light orbs are gathered, Ushio instead lives a happy life with her parents and does not suffer from her mother's sickness. In the epilogue, Ushio is shown sleeping under the same tree where Akio begged for Nagisa's life. She is found by Fuko who speaks a cryptic line, hinting at more things to come. In the movie, after seeing Tomoya so depressed, his father asks his friends to take him to a train station where he meets up with Ushio. It is hinted that Tomoya will stay with her and not end up like his father.
Youhei is Tomoya's friend and also a delinquent. He entered the school on an athletic recommendation in soccer, but was kicked out of the soccer club after being involved in a fight with other members who had a tendency of harassing the younger players. After this incident, he became lazy, becoming the only student with a higher absence rate than Tomoya. He is left-handed when it comes to sports and fighting, but he writes with his right hand, hinting that he is ambidextrous. He and Tomoya are known as the "Dirty Pair" in school. His hair is naturally black, but he bleached it blond after joining the soccer club. He was highly protective of his sister Mei when they were younger. One of the story paths involves him repairing his relationship with her. Youhei often gets punished or beaten up by various characters due to his obnoxious behavior, most notably Kyou and Tomoyo. Youhei plays a major role in some character paths, most notably the one revolving around him and his sister. In After Story, he is inspired to become a model and at Tomoya's request, attends Nagisa's fake graduation ceremony. He also visits Nagisa when she is pregnant. In the movie, while Youhei remains the central comic relief character, he is also depicted as being somewhat more serious about life, such as when he gets a part-time job to help his family through their tough financial situation. He also gets along much better with Tomoyo and actively tries, along with her, to get Tomoya out of the deep depression he had fallen into after losing Nagisa. According to the scriptwriters, he has the most appearances in the School Life arc.
Yukine is a second year student who hangs out in the library's reference room during lunchtime. Tomoya first meets her there while trying to find a how to book about speeches for Nagisa. He is immediately greeted by her hospitality and returns the next day with Youhei at his insistence. Tomoya, Nagisa, and Youhei then go to the library reference room routinely. She later gives Tomoya and Youhei a book on magical spells for them to try, most of which are in Tomoya's favor, involving the girls they meet. She has friends outside of school who turn out to be delinquents from other schools. She made friends with the delinquents through her brother, Kazuto, who was also a delinquent, after his death trying to save a friend from an accident. Tomoya learns briefly about the legend of the light orbs through Yukine which are called the symbol of happiness. The light orbs are actually the girl in the Illusionary World's wishes. According to the script writers, Yukine was originally intended to be one of the main heroines of Clannad, but as her story did not reach their expectations, she was made into a secondary character. However, she was still depicted on the regular edition cover of the PC release and on the PlayStation 2 release which used the same art as the regular PC release.
Ryou is Tomoya's classmate and class representative. She is the younger of the Fujibayashi twins. Unlike Kyou, she is timid and does not cook well but is otherwise good at chores. She is very keen about fortune telling, but her predictions, while incredibly specific, always manage to be either somewhat skewed or extremely wrong. Ryou is a major supporting character in both Kyou and Kappei's paths. In Kyou's path, Ryou has a crush on Tomoya and needs Kyou's help in pursuing him. In Kappei's path, she pursues Kappei instead which worries Kyou. Ryou has her own optional path where Tomoya pursues Ryou and they become boyfriend and girlfriend. This is considered Kyou's bad end. Later, Kyou finally admits that she is in love with Tomoya. This leads Tomoya to break up with Ryou because he realizes that he is really in love with Kyou. Kyou then cuts her hair as a sacrifice for hurting her sister, but Ryou assures her that it is okay and that she cannot help who she falls in love with. Ryou later becomes a nurse. In the visual novel, she is seen in Kappei's path five years later where she works as a nurse at the end of the story.
Misae Sagara is the resident manager at Tomoya and Youhei's all-boys dorm. She was Hikarizaka's first female student council president when she was in high school. She achieved a full week of perfect attendance for the whole student body and loved by the students. Misae is friendly with the dorm students but strict when it comes to the dorm rules. She is also well liked by the rugby members. Depending on decisions, Tomoya can change her into a violent dorm lady through his lecture. When Misae was young, she fell in love with a boy and hoped to one day see him again. It is later revealed that the stray cat she takes care of is actually the true form of the boy she is waiting for. When Tomoya tries to pursue Misae, the cat gives Tomoya a dream about Misae's past. When Misae was in high school, she was interested in a guy named Igarashi. One day, Misae meets a boy who introduced himself as Katsuki Shima and insists on granting her a wish as payment for encouraging him to recover. Misae's reluctance on giving him a wish to be granted and the boy's persistence causes them to spend time together and eventually develop romantic feelings for each other, especially after it is revealed that Igarashi already has a girlfriend. However, the boy realizes that his true identity is not Katsuki, but Katsuki's cat. Before dying, Katsuki gave the cat the duty of granting Misae a wish. To satisfy Katsuki's continual attempts to grant her a wish, Misae asks for him to love her forever. Having succeeded in his quest, the cat is returned to his original form without Misae's knowledge, leading her to believe Katsuki has disappeared. Meanwhile, she adopts what appears to be a stray cat. At the town's autumn festival, Tomoya tells Misae about her cat's true identity.
Yusuke is an electrician who once attended Hikarizaka High School and was a rock musician. Tomoya first met Yusuke during a street light accident involving a person's car and assists Yusuke in his work. Yusuke is engaged to Kouko and is one of the reasons why Fuko exists in the school. He marries Kouko in the middle of the School Life arc and first season of the anime. He plays a more prominent role in After Story, giving Tomoya a job as an assistant electrician at the Hikarizaka Electrical Company and, on occasion, offers words of advice. He has an odd quirk of sometimes randomly saying dramatic and often strange or incoherent phrases. Due to Tomoya's interest in him, Yusuke tells him of his past: how he became a rock musician, rose in fame, and then subsequently broke down after receiving news that one of his fans committed a crime. He was overcome with stress and despair which affected his music and eventually caused him to turn to drugs. After being rehabilitated, no one wanted him anymore except for Kouko, who had encouraged him to become a rock musician during high school. Throwing away his past, he now works as an electrician. Realizing that there are people who still love his music through Tomoya, Yusuke decides to make another CD about his love for the town. In the movie, he is Tomoya and Youhei's employer and is introduced trying to encourage Tomoya to come back to work. He gives Youhei a part-time job. He also plays a major role in facilitating Tomoya's reunion with his daughter in order to snap him out of his depression.
Kouko is Fuko's older sister. She used to be an art teacher at Hikarizaka High School and she treats everyone kindly. Kouko is a regular customer of the Furukawa Bakery and Nagisa admires her very much, being her former art teacher. She is engaged to Yusuke Yoshino and is the major reason why Fuko still exists in the school despite the fact she is still in a coma at the hospital. Thanks to Fuko's efforts, she eventually marries Yusuke. In After Story, she appears when Fuko is finally released from the hospital. In the movie, Kouko is depicted as still working at the school, being one of the teachers for second year students instead of an art teacher, and eventually becoming the supervisor for the drama club. She, along with Youhei and Tomoya, help revive the drama club for Nagisa.
Toshio Koumura is a language teacher at Hikarizaka High School and Tomoya's home room teacher during his first year. His age conceals his once vigorous past marked by his enthusiasm in teaching. He was friends with Kouko Ibuki three years ago. Five years ago, he was a strict teacher in an engineering school, well known for changing a lot of delinquents in the school for the better, but at Tomoya's school, his skill is not needed due to its prestigious image. It was because of him that Tomoya and Youhei met each other in the first place and it is heavily implied that he deliberately arranged this, knowing that if they had at least one good friend, they would have a reason to keep attending school and not drop out. He retires one year later, prior to the end of the school segment of the story. In After Story, he returns and organizes the fake graduation ceremony intended for Nagisa, arranged by Tomoya.
Kappei is a mysterious young man who is traveling around. His goal in life is "to live like a man". Tomoya meets Kappei if he chooses to avoid Kyou's scooter on the right side. Kyou intends to hit Tomoya as revenge for Botan coming home wet, but hits Kappei instead. While stunned, a kind girl helped him recover before leaving quickly. Unbeknownst to her, she left her handkerchief behind. Kappei's goal is to find a job and the kind person that he met after the crash. The kind person turns out to be Ryou and through her he finds a job at the hospital. They then become intimate. However, it is revealed that he has had osteosarcoma since he was young, hospitalizing him. He is also revealed to have once been a prodigious athlete. Kappei refuses to have his legs amputated even though it would cause him to die because he could not bear not being able to run, but is talked out of it mainly by Ryou and Tomoya, who were encouraged after having received advice from Yusuke. Ryou eventually convinces him to get cured through several methods, one of which is threatening to get pregnant with his baby while he sleeps. Ryou also informs Kappei that a new technique of treatment using liquid nitrogen would not require an amputation. This encourages him and he finally decides to get the operation. Five years later, Tomoya visits the hospital again to see Kappei, who is in therapy for recovery, and Ryou, who is working as a nurse. Kappei eventually marries Ryou. Kappei is the only character in the visual novel who does not appear in any of the animated adaptations.
Naoyuki is Tomoya's father. His wife, Atsuko, died in an accident when Tomoya was young, thus leaving only himself to raise Tomoya. Afterwards, Naoyuki turned to alcohol and gambling and frequently fought with his son. One day, while arguing with his son over trivial matters, he slammed Tomoya against the wall so hard it dislocated Tomoya's right shoulder and sent him to the hospital where it was declared to be untreatable, ending his basketball playing. Since then, Naoyuki has treated Tomoya more kindly, but like a stranger rather than family. This only hurt Tomoya even more, so he became a delinquent to avoid returning home early enough to have to deal with his father. Kotomi's path reveals he wants to run away from home. After moving in with Nagisa, Naoyuki comes to see her play, much to Tomoya's surprise. In After Story, Naoyuki is sent to prison where Tomoya visits him despite this preventing Tomoya from ascending in his job. He visits him again later to tell him that he is going to marry Nagisa to which his father consents. Five years later, it is revealed by Shino that Naoyuki sacrificed everything in his life for Tomoya's sake so that Tomoya could grow up to be a proper man, unlike him. Tomoya finally understands what his father went through and decides to forgive him, admitting that he indeed was a good parent. After Tomoya comes to terms with his father, Naoyuki decides to return to his hometown to stay with his mother, claiming his role as a father has finally come to an end. In the movie, Naoyuki is shown to work a graveyard shift with hardly any time to come home instead, though it is clear that he still had alcoholic tendencies while Tomoya was growing up hence their estranged relationship. He is also depicted as being more consciously aware of his actions and more actively trying to repair his relationship with Tomoya, going out of his way to have a talk with him and even contacting Tomoya's friends and family to orchestrate a trip for Tomoya so he can spend time with his daughter Ushio in order prevent his son from becoming like him.
Shino is Tomoya's paternal grandmother. She only appears in After Story. During Ushio's path, when Ushio is finding her toy robot she lost in the flower field, Tomoya meets Shino at the edge of the cape, who introduces herself to him and their meeting is planned by Sanae. Shino tells the story of Naoyuki's past and the tragedy after Atsuko's death which is similar to what Tomoya is facing after Nagisa's death, along with his sacrifices made for Tomoya just to see him grow up to be a proper man. After listening to Shino's recounting of his father's story, Tomoya feels deep remorse for having neglected his daughter and for how he had treated his father who he now realizes loved him all along and decides to mend his relationship with himself, Ushio, and his father. Shino tells Tomoya to relay a message to Naoyuki that she wants him to return home so she can be with him, which Naoyuki agrees to after finally making amends with Tomoya.
Akio Furukawa (古河 秋生, Furukawa Akio)
Voiced by: Ryotaro Okiayu (Japanese); Andrew Love (English)
Akio is Nagisa's father and Sanae's husband. He looks younger than he is and is shown to be an avid smoker. Although he often talks and plays rough, in addition to having a reckless personality, he is kind and sympathetic. His childlike side makes it easy for kids and adults alike to befriend him. He runs the Furukawa Bakery with his wife, Sanae. Akio often displays his love for his wife. In his spare time, Akio plays baseball with children in the small park next to the bakery and is a fan of Gundam and Star Wars. He is often the victim of Sanae's strange concoctions, frequently insulting her bread unaware she is in the room and consequently having to eat the bread in front of her while claiming that he loves it in order to pacify her hurt feelings. During the School Life arc, it is revealed Akio had been a talented aspiring actor in a theater company, but had to quit his job due to Nagisa's bad health. Akio takes over Youhei's role as the comic relief during After Story, however, he can be serious when needed as he often gives advice to Tomoya on what it is like to be an adult and a father. He tells Tomoya the story about how Nagisa almost died due to his and Sanae's unintended negligence. Nagisa had been sick with a fever, but because Akio and Sanae were unable to get time off from work, they left her home alone. When Akio came back to check on her, he found her collapsed outside in the snow as she had attempted to go outside to wait for her parents to come home. Desperate, he ran through town while holding Nagisa and crying, praying that she would not die. When he came upon a clearing with a light, Nagisa woke up. Akio expresses a belief that after she was saved, Nagisa's health became connected to the town.
Sanae Furukawa (古河 早苗, Furukawa Sanae)
Voiced by: Kikuko Inoue (Japanese); Kara Greenberg (English)
Sanae is Nagisa's mother and Akio's wife. Normally, she is very childish and a crybaby, but when needed she can be very strong-willed and dependable. She runs the Furukawa Bakery with her husband and often invents strange new concoctions to make breads that are anything but edible and almost never sell. Outside of the bakery, she tutors children. She looks younger than she is and so is frequently mistaken for being Nagisa's older sister instead of her mother and is even able to pass as a high school student if she dresses a certain way. Sanae plays a larger role in After Story, often coming to Tomoya's aid when Nagisa is sick and needs to be accompanied, especially during Nagisa's pregnancy. Before becoming a baker, she was a middle school teacher and had to quit her job due to Nagisa's bad health. Sanae is the mastermind behind Tomoya and Ushio's trip to the flower cape, hoping they will reconcile. She knows Shino, Tomoya's paternal grandmother, although it is never revealed how they met. She also pretended to be Youhei's girlfriend to show his sister, Mei, that he does have a future but Mei finds out that they are faking it. In the movie, instead of being a teacher, she was an actress in the same troupe as Akio before having to quit in order to take care of Nagisa.
Mei is Youhei's younger sister who loves Youhei and lives in the countryside. She is a smart girl who likes to see new things and is a fan of Yusuke Yoshino. Worried about her brother's situation, she calls Youhei, but Tomoya answers instead and, pretending to be Youhei, tells her to come visit. Mei's personality is the opposite of Youhei's. She can be very nosy about things, like trying to further Tomoya's relationship with Nagisa or learning about Youhei's current situation. Although Youhei tries to avoid Mei, he still cares for her as seen when he stands up for her when she gets bullied by the soccer club. The two siblings eventually grow closer as a result.
The only human in the Illusionary World, a world that both Nagisa and Tomoya have dreams of, and is the basis for the play Nagisa puts on after successfully reinstating the drama club. The girl creates a body out of junk for an unnamed entity only referred to as "I" so that she will not be alone anymore. At the edge of death after failing to get away from the world, it is revealed that she is actually Ushio who had lost her memory after dying in the real world, regaining it just long enough to inform the junk robot that they have a linked past and that he is actually her father, Tomoya. She created the Illusionary World in order to collect enough lights to make a miracle possible to save her family from their tragic fate, although she holds no recollection of this. In Clannad's epilogue, she is shown sleeping under the tree where Akio had once begged for Nagisa's life long ago and is apparently seen for a brief instant by Fuko, though it turns out to be the real Ushio.
The nameless robot who narrates events in the Illusionary World as seen through Tomoya's dream while referring to himself only as "I". His body was created by the girl in the Illusionary World out of junk so that she would not be alone. The robot is about half the girl's height and cannot talk as he had been created without a mouth, so he relies on body language to communicate with her. When on the edge of death in the Illusionary World, the girl is revealed to be Ushio and she informs the robot that he is her father, Tomoya, and tells him to collect light orbs to create a miracle that will save their family from the tragedy that has befallen them. He later succeeds in doing this. In the anime, he is sent back into the past where his past self, with memories of the bad future, reasons that if he had never met Nagisa, neither of them would have suffered. He seems about to change history so that they never met each other, but then he and his other self, the junk robot, become one mentally and ultimately decide to meet Nagisa, who also remembers the future and had hoped that he would not regret meeting her. After this, they wake up in a world where Nagisa survives.
Rie is a second-year student at Hikarizaka Private High School who used to play the violin as a child and won many competitions. She had a lot of talent and was supposed to study abroad, but she was involved in an accident. As a result, her grip became weak and she was unable to play the violin as well as she had previously been able to, having lost her main aim in life. However, when she entered high school, Toshio Koumura taught her about chorus and she discovered that she could sing very well. Thus, having discovered a new reason to live, she decided to form a choir club with her friends. Her best friend is her fellow club member Sugisaka. Kotomi befriends her when Rie lends her her violin. Rie wishes to go to music school after graduation. In After Story, Rie attends Nagisa's fake graduation ceremony and starts working at a family restaurant with Sugisaka as waitresses. She eventually gets Nagisa to work there as well.
Sugisaka is a member of the choir club. She appears when Nagisa asks them if they could have Toshio Koumura as their supervisor. Sugisaka refuses and even threatens to hurt Nagisa if she tries to reestablish the drama club. Youhei, Tomoya, and Nagisa eventually confront her after school. Sugisaka later explains that Rie used to play the violin well when she was little, but got into an accident. When Rie went to high school, she and her friends formed the choir club since Rie always looked lonely and could sing. She then begs Nagisa to not get in her way, but Youhei calls Sugisaka a cheater for trying to get their sympathy. She appears with Rie to watch Youhei, Tomoya, and Kyou go against the basketball team. When Tomoya and the others won the match, Sugisaka relented and compromised with Nagisa to share Koumura as a supervisor for their clubs. In After Story, Sugisaka and Rie attend Nagisa's graduation and the two are later seen working with Nagisa at a family restaurant as waitresses.
