List of Komi Can't Communicate characters

The manga series Komi Can't Communicate features an extensive cast of characters created by Tomohito Oda. The story mostly takes place at the elite Itan Private High School, and follows Shōko Komi, who is suffering from a crippling social anxiety disorder on her quest to make 100 friends with the help of her classmate Hitohito Tadano.

Main characters

 * Shōko Komi (古見 硝子)
 * Komi is a high school girl who suffers from extreme social anxiety, which prevents her from communicating with other people. Komi has long, black hair with a purple tinge, and described as extremely beautiful. Komi is usually drawn with a detailed face and almond-shaped eyes. When she is anxious, shocked, surprised, or on many other occasions, her appearance switches to a simplified face dominated by very large, round eyes. When Komi is excited, cat ears tend to appear on her head, of which Komi and sometimes others are aware. She tends to motivate herself by pumping both fists.
 * Due to her communication disorder, Komi never had been able to make friends in elementary and middle school. Because of this, she feels lonely when entering high school. Her wish is to befriend 100 people before graduation from high school. Due to Komi's beauty and aristocratic-like demeanor, she is very popular among her classmates and quickly garners an adoring, but distanced following. Komi's silence tends to be mistaken as stiff properness, despite her simply being too afraid to talk. Her big-eyed, anxious look after having been addressed is often mistaken for anger, further deterring other people from becoming close to her. Initially, Komi is completely unable to speak with anyone outside her family. Even there, she speaks so rarely that even her brother dismisses the possibility of having heard her voice. When Komi tries to speak, she either freezes completely or stutters severely.
 * Over the course of the story, she slowly learns to talk to others first over a phone and speak short sentences in person. By her second school year, she is able to hold longer conversations when emotionally invested. When she is in her third year, she can speak more competently with little stuttering, even amongst a group of people.
 * Her social anxiety also leads to her being very insecure and overthinking her actions. Komi is also quite pessimistic about herself, usually believing that any misunderstandings are a result of her own fault. Despite everyone's praises of her, she still tends to consider herself to be boring and uninteresting, and unworthy to be with Tadano.
 * Hitohito Tadano was the first one (outside her family) to recognize her social anxiety, and who became her first ever friend since childhood. Tadano has since helped her find more friends and overcome her social anxiety, with the assistance of Najimi. Komi quickly develops romantic feelings for Tadano, but is for the longest time too shy and worried to express her feelings or to act on them. Only after Tadano confesses his own feelings to her, she is able to do so and the two become a couple. Over the course of their relationship, Komi becomes more flirtatious, desiring affection from Tadano, by being more forceful and playful, and by teasing him.
 * Komi is a very kind and caring person, and tries to help others whenever possible. Despite her anxiety, Komi is a very good student, usually being at the top of her class in tests. She is also good at sports, allowing her to be a serious competitor to the very sportive Chika Netsuno. She only learns how to ride a bike when Tadano teaches her, though. Komi likes to read and is a good cook. She is very fond of cats and owns several plush cats and cat dolls. After learning about a cat café in her town, she quickly becomes a regular and befriends the normally very distanced black cat Chocolat.
 * Aside of Tadano, her closest friends are Manbagi, Katō, Sasaki, Ase, and Isagi.
 * Her name Komi, when written in the Japanese order, refers to the Japanese term komyushō (コミュ症).

 * Hitohito Tadano (只野 仁人)
 * Tadano is a student at the prestigious Itan High School and Komi's seatmate. He has short black hair with a white flower-shaped cowlick. A recurring joke is that Tadano is otherwise completely average: he is of average size (for a Japanese teenager), has average grades, shows average performance at sports, etc. When first enrolling at Itan High, He intended to be completely normal and not stand out, but his plans are foiled when he meets Komi on his first day at school and discovers her communication disorder. As such, he befriends her and promises to help accomplish her dream of having 100 friends, with him being the first.
 * In middle school, Tadano was a chūnibyō: he slicked back his hair, popped up his collar, and tried to act cool. After embarrassing himself by a failed attempt to confess his love to his classmate Kawai, he dropped the persona and decided to become completely normal.
 * Initially, Tadano was quickly ostracized and belittled by most of his first-year classmates, mainly due to their jealousy of his increasing closeness with Komi, and their perception of him being plain and uninteresting as a person. Over time however, he garnered more acceptance and friendship, due to his own friendly nature, and the kindness and understanding he would show others. Some students recognizing his qualities right from the start.
 * During his second year, he quickly became acquainted with the new students, and was fully respected and liked as a fellow classmate. Over time, even other students started to acknowledge Tadano's and Komi's bond and became supportive of their relationship.
 * Tadano's friendly demeanor initially leads to him being taken advantage of. He was pushed into being the class representative when no one else wanted to, or used by his teachers to take over their menial tasks . On several occasions, he find himself forced to cross-dress. Tadano's closest friends besides Komi and Najimi are Katai, Naruse, and Kometani.
 * Along with his kindness, Tadano has an almost uncanny ability of perceptiveness, being able to accurately guess the true thoughts and feelings behind a person. This perceptiveness is what helped Tadano figure out Komi's true personality and insecurities and establish a friendship with her. Due to this ability he can act as a translator of a kind for Komi and other characters with similar communication disorders, like Katai, Katai's father, or Ogiya, and helps them to express their true feelings and intentions. Despite Tadano's perceptiveness he can still be normally dense at times, for example not grasping Komi's or Manbagi's attempts to flirt with him.
 * Tadano very quickly develops romantic feelings for Komi, but rejects the idea of her being interested in him for the longest time. As a result, he does not act on his feelings and prefers to set them out of mind, until Manbagi – who also fell in love with him – makes him acknowledge his hidden love for her. After he confesses to her, the two become a couple and start dating. Over the course of their relationship, Tadano becomes more truthful and open to his desires for Komi.
 * Tadano lives with his parents and younger sister Hitomi in a fairly small flat in an apartment block where he and Hitomi share a room together. For a time, both his sister and mother came to believe that he might be gay, based on misunderstandings of the apparently romantic-like friendship with Katai, and Tadano cross-dressing on several occasions . They eventually relent on this belief after Tadano formally introduced Komi as his girlfriend to them. He is very enthusiastic about old buildings and want to become a teacher after school.
 * Tadano's name is a play on words: tada no hito (ただの人) means "an ordinary/average person", and "hito" (仁) means "human" or "compassionate".

In Middle School, they dressed in a boy's uniform but in High School, they primarily dress as a girl (wearing a skirt but a shirt with a necktie instead of a ribbon).

 * Najimi is socially extremely skilled and everybody's friend. Through their social ability they are able to become friends with anyone in a few minutes. Despite their social skills, Najimi initially did not want to become Komi's friend: they had already met Komi in elementary school and attempted to befriend her, but got scared off by Komi's silence and staring. Only after Komi "saved" them from some unwanted suitor, Najimi warms up to Komi.
 * Especially early on, Najimi is a crucial catalyst for Komi getting more acquainted to social situations by organizing get-togethers and trips during summer vacation, involving her in games, or making Komi order food for them in cafés and sandwich shops. Najimi also instigates situations in which Komi and Tadano get to know each other better, thus furthering their romantic relationship.

Nakanaka is the singer and writes the lyrics.
 * Her relationship with Yamai is characterized by dispute, with both of them vying for Komi's affection. Despite this, there is also an underlying friendship between them as they also support each other, e.g. when Yamai coaches Nakanaka's band or when Nakanaka and her bandmates provide Yamai moral support after Komi got together with Tadano as a couple.

Motivated to want to try taking a chance with Manbagi, he invites her to spend some time at the summer festival. After which, he comes to enjoy the time he spent with her. Later that evening, when Manbagi starts to belittle herself regarding the failed relationship with Tadano, he tries to tell her the values he sees in her, attempting to yell over the fireworks. When unfortunate timing makes his words sound like a love confession, he panics and attempts to avoid her at school, for fear of what her reply would be regarding him. After then being cornered by Manbagi and pressured into explaining himself, he acknowledges that he has truly come to like her and takes responsibility for his accidental confession. Manbagi, while happy about his feelings for her, tells him to give her more time for a proper reply, ending the meeting with a smile. His name can be read as 若い 健人志 (wakai taketoshi), meaning "a young and healthy person".

Komi's Family

 * Shōsuke Komi (古見 笑介)
 * Shōsuke is Shōko's younger brother. Like his sister and father, he tends to be silent, but unlike them he is perfectly capable of talking but just chooses not to. He is tall and handsome and easily gets the attention of girls, but is uninterested. Like his father in high school, Shōsuke is sportive and gifted with his hands. And shown to be capable of excelling in any kind of task or skill.
 * Shōsuke has a far more introverted nature than his sister, and prefers to keep to himself most of the time. But he is also quite antisocial, as interacting with anyone, even his family, appears to be bothersome and a chore for him. Even considering the timid Yamada to still be annoying. He has an unwillingness to leave his house, and will avoid most interactions with people, except when it's about transacting business (paying at the register). He nevertheless has a good-natured side as well, such as saving Tadano and Rei on different occasions, and repairing Rei's toy.
 * While Shōko is in her second year, he attends the Kisai High School, where he ends up as seatmates with Tadano's younger sister Hitomi. Hitomi mistakes his introversion for a social anxiety disorder and immediately makes it her duty to help him overcome it. Her incessant attempts to forcibly push him into social interactions tend to exhaust Shōsuke. Katai's younger sister Ai falls in love with Shōsuke, but he has yet to show if these feelings are mutual.
 * His name is the same play on words as his sister's on the word {{Nihongo||コミュ症|komyushō}|communication disorder}}.

As Shōsuke's seatmate, she presumes that he suffers from a communication disorder and takes it upon herself to help him make friends. Which she does by forcing him to interact with her and their classmates, and pressuring him into partaking in class activities. She has no romantic interest in him and only sees him as friend.
 * In contrast to her brother, who is average at everything and anything. Hitomi is shown to be talented and unique. She is able to accurately mimic Shōsuke's voice and speak through ventriloquism, skilled in Judo, being sportive and blocking a goal shot from Shōsuke, able to overpower people bigger than her, and correcting the mistakes at Hitohito's attempt at a novel. But in the same way, she is not as perceptive as her brother, and will easily jump to supposed conclusions.

She quickly notices the romantic attraction between Hitohito and Komi, but after having seen Hitohito in drag and with together Katai, she begins to assume him to be gay. Hitomi and Hitohito share a single room in their family's apartment.
