He once won 1st place in a competition but his brother stormed the place and ripped his certificate apart, all while screaming "Who cares about this shit?! Learn your damn math!!".

School employees

 * Ubuyashiki Kagaya: Administrative director. He comes from quite the rich family, so besides the academy, he’s involved in many other enterprises. He’s particularly skilled at networking, so whenever he takes something on, there are plenty of people willing to put effort into seeing it through. The wounds on his face are from a random passerby assailant who threw dangerous chemicals on him. People say this might be because he bares such a resemblance to Diet Member Kibutsuji that they might be mistaken for twins. He works against Diet Member Kibutsuji with the help of good politicians who graduated from Kimetsu Academy.
 * Amane Ubuyashiki: Principal, and Kagaya’s wife. She really loves kids and is passionate about education, but because she tends to be a bit expressionless, the students are a little afraid of her. Since there’s such a mysterious air to her, some of the students worship her.
 * Otogawa Nakime: Vice principal. She's one of Kibutsuji’s spies at Kimetsu Academy.
 * Giyu Tomioka: P.E. teacher. He's such a spartan that several complaints have been issued about him from the PTA, and the Board of Education might even have to make a move.
 * Kyojuro Rengoku: History teacher. Because of his passion of teaching and his love of history, he began hurling his students and starting cavalry battles during class. He's loved by his students, and nobody in this academy has terrible grades in History.
 * Tengen Uzui: Art teacher. The students call him "Gangsta Sensei," and he's known for yelling that "art is an explosion" before then blowing up the classroom with dynamite. It's rumored he was spotted in a fight during his high school years, and that he's probably good at fighting since he was once a gang leader.
 * Gyomei Himejima: Civics teacher and first-year homeroom teacher. Since he's so muscular, students were afraid of him at first. But because his personal belongings generally have cats on them, everybody quickly became aware that he's a nice person who likes cats. There have been many incidents of people calling him Dad on accident.
 * Sanemi Shinazugawa: Math teacher. He always keeps his collar open, because he feels stressed when it gets stuffy around his neck. He never buttons up for important family celebrations. When one of his students said that "Nobody needs math in the future", he tossed said student out the classroom window like in Smash Bros and this became known as the Smash Bros. Incident. There was a "Kill Sanemi-sensei" plot for a while, but after the Smash Bros incident that plan disappeared. He's very kind to elders, women, and children. Though kids tend to cry when he gets close to them. He talks a lot to Kanae.
 * Kanae Kocho: Biology teacher and Flower Arrangement Club advisor. She is a graduate of the Academy and has been chosen as one of the three beautiful girls in the Academy for three years straight. She is popular among boys and girls. Anyone who speaks bad of her actually gets embarrassed to talk to her in her face. She is very gentle, but also mysterious. She has been seen sticking talismans on walls and chanting something like "Rin Pyou Tou Sha...", does she have spiritual powers?
 * Kyogai: Music teacher. He primarily uses a tsuzumi drum when he holds class. He's often made to do long songs and orchestral pieces from noh and kobuki dramas, so his students aren't able to sing modern songs properly.
 * Obanai Iguro: Chemistry teacher. He has an allergy to women and always wear a mask. It is said that he keeps a snake around him in order to avoid contact with women. He often goes to Aoi's family's restaurant, but only ever orders tea. He would frequently ask if the "girl with the braids" (Mitsuri) is coming over. When students fail tests, they are crucified to a post and shot at with bottle rockets.
 * Sakonji Urokodaki: School janitor.
 * Suma: School store employee. She gets the change wrong a lot.
 * Hinatsuru: School cafetaria employee. She is insanely good at cooking and they say she has God's tongue.
 * Makio: School cafetaria employee. She is loud, moves fast and she snaps easily.

Other characters

 * Diet Member Kibutsuji: Evil politician. He’s trying to take over Japan. There’s a rumor he’s from the Ubuyashiki family line. He’s always irritated because whenever he’s trying to do something evil there’s always someone who gets in his way. He believes this is all because Ubuyashiki is paying people off, so Kibutsuji has placed spies in many places to try to crush Ubuyashiki’s network and finances. It seems he has a fan club.
 * Kokushibo: Diet Member Kibutsuji’s secretary. Although he’s a secretary, he’s so buff that he often gets mistaken for a bodyguard. There are rumors that he was a member of the American Special Forces, or that he’s a master at Iaido, or that he killed a man with his bare hands, etc.
 * Doma: Beyond fake marriages, he is a scam artist in various ways. He is infamous to the point that he gets covered in special programs on TV. He's also been involved in several incidents, but because the evidence is insufficient, he has yet to be prosecuted. After greeting a woman with pink and green hair, he went missing afterward. Earlier at the crime scene, the voices of a man and a woman fighting were overheard saying "I had a feeling you were lying".
 * Yushiro
 * Swamp Demon: Weird man who hangs out around Kimetsu Town and targets 16 year old girls through pinpointing. Because he's often witnessed frequently and the incidents occur at the same time, he's become something of an urban legend. Tanjiro has so far deduced that he's not a triplet, but is still pursuing this case.
 * Hisa: Inosuke's foster parent. Her specialist dish is tempura, one of Inosuke's favorites, and it's said that whenever something goes wrong, she just pretends to have bad hearing.
 * Ayaki Rui-Kun: He became famous overnight because he won the cat's cradle tournament. He even got a special article written about him in Kimetsu Town. His peculiar facial moles became a hot topic on the internet because they were cute.
 * Shinjuro Rengoku: Kimetsu Town Sword Dojo teacher. He's been getting disheartened as of late, because he's been losing pupils.
 * Ruka Rengoku: Calligraphy teacher. She has a weak expression, so everyone's been worried about her recently.
 * Tamayo

Episode 1: Teacher Giyu asks students to introduce themselves. Tanjiro, Inosuke and Nezuko comply, but when it's Zenitsu's turn his seat is empty.

While running, he gets caught by Giyu who punishes him for running in the halls.


 * Characters: Giyu, Tanjiro, Inosuke, Zenitsu, Nezuko

Episode 2: Teacher Giyu orders the class to change clothes and head to the field for a P.E. lesson. Inosuke is down because he lost to someone smaller than him (Kanao) during track running, while Tanjiro is beaten by Susamaru and Yahaba during dodgeball. However, Zenitsu loves P.E. even though he lost to Aoi on track, because it allowed him to gaze at her from behind, and when she aimed a dodgeball at him, he perceives that as her paying attention to him. Giyu hears what he said and punishes him again.


 * Characters: Giyu, Tanjiro, Inosuke, Kanao, Susamaru, Yahaba, Aoi, Kiyo

Final Episode: Zenitsu has clothing inspection duty. Initially he hated it, as he has to arrive early at school, but upon seeing female students Nezuko, Kanae and Kanao in their uniforms he remembers why he keeps doing it. When Inosuke arrives, he orders him to button up his open shirt, but Inosuke gives him a head butt instead. When Tanjiro arrives, he orders him to remove his Hanafuda earrings, but Tanjiro apologizes for going against the school rules and tells him they are his father's. Zenitsu wants to let him go, but Giyu arrives to stop Tanjiro, who runs away from him. Giyu then runs after Zenitsu, yelling at him that he should dye his hair black.

Kimetsu Academy: Valentine Edition
Kimetsu Academy: Valentine Edition (キメツ『バレンタイン』) - A special version of Kimetsu Academy featuring a Valentine theme.

Episode 1: Zenitsu is excited for the next Valentine's Day, which is still a half year away. He wants to get at least one chocolate from girls and starts preparing for it by pushing Tanjiro to accompany him asking teachers how to be popular with girls. They first go to Kyojuro, the History teacher who received a total of 28 chocolates. Kyojuro thinks it's because he speaks with deep breaths and his mouth wide open, such that the back of the class can hear him. Zenitsu considers it's bullshit and walks away. Tanjiro apologizes for Zenitsu's behavior and tells him he's wrong for behaving like that to a teacher, but Zenitsu shouts back loudly, so loud that the teachers in the backoffice can hear. Sanemi comments he wants to punish the student for shouting, and Kanae identifies the voice as Zenitsu. Kyojuro proudly confirms and praises Zenitsu for letting it all out.


 * Characters: Zenitsu, Tanjiro, Kyojuro, Sanemi, Kanae, Gyomei, Kyogai, Obanai

Episode 2: The next teacher they ask for advice is P.E. teacher Giyu, who received a total of 31 chocolates. Giyu says he never thought to be popular, but Zenitsu again calls it bullshit. Tanjiro shouts at Zenitsu for offending Giyu, saying that Giyu is already eating alone. Giyu in turn is offended by this comment and claims he's not alone. He also says that communicating is not necessarily talking, by staring at each other's eyes, one can understand each other's feelings. Zenitsu thinks this advice is a waste of his time and leaves. Tanjiro apologizes again for Zenitsu's behavior and follows him.


 * Characters: Giyu, Zenitsu, Tanjiro

Episode 3: Sanemi runs after Inosuke, trying to stop him from running in the halls and requesting him to remove the mask. They run past the Art Room, where Zenitsu is asking Tengen for advice. Tengen, who received a total of 51 chocolates, thinks from elementary school to high school the only thing a boy needs is fast legs. He claims that it's because the school fairy casts running magic on the female students. From college onwards, Tengen believes it's all about money. Tanjiro thinks it's a wrong way of thinking and that way you won't find true love. Tengen is flabbergasted hearing this and dismisses them. While they walk in the halls, Tanjiro tells Zenitsu that if he lives his life honestly and works hard, a girl will appreciate it. In the art room, Tengen gets upset about Tanjiro's words and throws a dynamite at a wall. The explosion can be heard in the teacher's backoffice. Giyu recognizes that it's Uzui again, and Kyojuro expresses that art is an explosion.


 * Characters: Inosuke, Sanemi, Tengen, Zenitsu, Tanjiro, Kanae, Gyomei, Kyogai, Obanai

Last Episode: Homeroom teacher Gyomei announces that a pervert has appeared and asks the students to take a good look at the handout. Tanjiro reads the description in the handout and recognizes all the traits the three teachers has given Zenitsu. He immediately knew it's Zenitsu, who is crying at the back of the classroom. On Valentine's Day, Tanjiro greets Zenitsu, who is miserable as he's mistaken as a pervert and believes he won't receive any chocolate, and he is also assigned morals duty on that day. Tanjiro gives him a heart-shaped chocolate bread made by Nezuko, who happily jumps in the air, as he is sure the chocolate is filled with Nezuko's love. Tanjiro also gives Inosuke, teacher Giyu and Urokodaki a chocolate bread.

Kimetsu Academy: Christmas Edition
Kimetsu Academy: Christmas Edition (キメツ『クリスマス』) - A special version of Kimetsu Academy featuring a Christmas theme.

Episode 1: Zenitsu invited Nezuko over to his Christmas party/Wedding filled with an enourmous double-barrel cake with small Zenitsu and Nezuko brides at the top, presents and fried turkey. He hears the doorbell ring and opens the door to see Nezuko along with Tanjiro, Inosuke and Giyu wearing a samurai armor with the kanji for Flame (炎) inscribed on its cuirass, tribal clothing and a black tuxedo with a blue tie and a white geisha mask, all worn respectively for the three males. This all deeply shocks Zenitsu as he never invited the others to the "party", even while it's shown that Zenitsu was never invited to other parties himself.
