With its astonishing combination of comedy, slice of life, and classic shounen storytelling, Assassination Classroom has been on a lot of people’s favorites list and, without a doubt.

Relevant to all these shenanigans, got a character that’s close to your heart? Check out our list of Assassination Classroom Character Birthdays! Who knows? You might end up finding your birthday twin.
BIRTHDAYS OF ASSASSINATION CLASSROOM CHARACTERS
JANUARY
Gakusho Asano
January 1
Fitting for the first of January, is the Chairman’s son, Gakushu Asano. Asano, a straight-A student, and a straight ‘A’ person (Attractive, Astute, and A total A*hole) is Kunugigaoka Junior High School’s Student Council President, the leader of the Big Five, and the academic antagonist to class 3-E.
Ritsu
January 1
The first of January just doesn’t run out of number 1s! Another celebrant for this day is 3-E’s first and youngest transfer student, Ritsu. Originally an AI with a screen that shows her face and shoulders for a head, and a box filled with all sorts of artillery for a body, this 14-year-old AI got an upgrade from Koro-sensei, changing her small display screen to a full-length one, making her the first Vtuber, just kidding… Or are we? I’m sure one of you are into Anime with OP Transfer Students.
Kaede Ayano
January 9
Class 3- E’s ‘Forever Flat’, Kaede Ayano celebrates her birthday on the 9th. Coming off as a typical middle school girl; kind and with a love for all things sweet, this retired actress is one girl you don’t want to mess with unless, of course, you’re her dear friend Nagisa.
Kotaro Takebayashi
January 29
Don’t let the lack of eye contact fool you, Kotaro Takebayashi is definitely a man of culture!
Born from a family of elite doctors and celebrating his birthday on the 29th, this 2D waifu-loving boy felt out of place in class E but with his analytical skills, risk management, and penchant for explosives, he soon realized he was exactly where he belonged.
February
Kouki Mimura
February 1
He may be plain but Kouki Mimura’s skills are anything but ordinary. Our first February birthday boy who celebrates his special day on the first of the month is blessed with immaculate vision. As class E’s Mushroom Director, he can spot anyone a hundred meters away, whether this skill helped his talent as a director or vice versa, who knows?
Yuzuki Fuwa
February 9
A girl after my own heart, Yuzuki Fuwa, celebrates her birthday on February 9th and is the last of our
February celebrants. With her imaginative and enthusiastic personality, it’s not hard to picture that she is a shounen manga fan. She also has a photographic memory and great investigative talent that has gotten class E out of tight spots. Now if only I can also develop a photographic memory to reference all my mangas…..
March
Yukiko Kanzaki
March 3
The Yamato Nadeshiko of Class E, Yukiko Kanzaki, opens for our March celebrants with her birthday on the 3rd of the month. Tired of the pressure from her father to be the ideal woman, she dropped everything and devoted herself to video games, specifically shooting games giving her great marksmanship. You’d think with all that femme fatale energy boys would be more careful with her heart but her looks and seemingly passive personality seem to attract the worse type of people. I guess that’s just one mark she will always miss.
Koro-sensei
March 13
The magnanimous teacher of class E, Koro-sensei comes next! Before he went out with a bang, he celebrated his birthday on the 13th of March. He wasn’t always the lovable yellow octopus-looking sensei we knew him as, he was an assassin with thousands of kills under his belt who unfortunately got apprehended and made into a test subject. He killed class E’s homeroom teacher in an accident and vowed to help her students to make it up to her.
Itona Horibe
March 31
Class E’s secret weapon, Itona Horibe, shares more than just Koro-sensei’s love for sweets and gravure magazines, they also share the same birth month with Itona’s birthday celebrated on the 31st of March.
Having been exposed to the same experimental matter as Koro-sensei they were perfectly matched making him the perfect antagonist to the class. However, after an incident that caused him to go out of control, Koro-sensei, with the help of class E, showed Itona who really had the superior tentacles.
April
Hinata Okano
April 2
You’ve heard of Dance Monkey, now give it up for our April 2nd celebrant and class E’s Amazing Monkey, Hinata Okano! Initially more serious-looking, she blooms to be more playful and maybe even a little stubborn especially once she gets angry.
Lovro Brovski
April 7
A hitman dealer and class E’s special instructor, Lovro Brovski celebrates his birthday on the 7th of April.
Even as a retired hitman, he was more than capable to hone class E’s assassination skills and even mentored Nagisa and taught him his Clap Stun Technique.
Ryouma Terasaka
April 10
Class E’s resident delinquent, Ryouma Terasaka, celebrates his birthday on the 10th of April.
His brawn-over-brain approach has proven ineffective in Kunigigaoka. We see him improve the more the class spends time with Koro-sensei, even taking the 46th overall rank in Kunigigaoka’s final exam. As an assassin, his talents lie in the perfect execution of tasks, stamina, and strength.
Gakuho Asano
April 12
Kunigigaoka’s chairman and the father of Gakushu Asano, Gakuho Asano is the last celebrant of April, on the 12th. Once an educator just like Koro-sensei, he was hardened by the apparent suicide of his pupil and has since then believed he has to focus on churning tough students instead, he developed his own ideals and would do anything to make sure they come to fruition. After tasting defeat against Koro-sensei, he has since mellowed down and has somewhat reverted to his old principles in teaching, here’s to hoping it stays that way this time.
May
Kirara Hazama
May 6
Her name might be similar to kirakira (shiny, glittery, beautiful) but Kirara Hazama seems to just be the opposite of that. Despite that, she is still our celebrant for May 6! Quiet and unassuming, she loves reading and takes pleasure in spooking others, even as a little girl. It’s most likely due to the latter that she excels in intimidation as well as spinning macabre and depressing tales just like that class play that made the whole school lose their appetites!
Sumire Hara
May 8
The homemaker of class E, Sumire Hara, celebrates her birthday on the 8th of May! With an unassuming and motherly personality you may just forget that this girl is the second best female marksman in the class, her craftsmanship is also top-notch that she can make hidden traps out of regular household items. So next time you see Sumire, maybe keep that in mind before you comment on her weight.
Ryunosuke Chiba
May 20
The class calls him the Adult Game Protagonist but there is more to Ryunosuke Chiba, our May 20th celebrant, than his rarely seen eyes. Being often teased for his intense gaze he has decided to grow his hair over his eyes. Lucky for him though, his hair seems to act like gunsight giving him the best marksman ability in the class. Aside from this, he seems to be very observant and empathic, easily able to pick up on others’ distress and cheer them up.
June
Taiga Okajima
June 9
Taiga Okajima, the class pervert, is our first June celebrant, with his special day being on the ninth. He excels in photography and seems to have great knowledge of cameras, proven by his ability to find exploits in security cameras. Aside from this already terrific feat he also ranks fourth in class when it comes to knife work. Maybe his catchphrase “perversion can save the world” does have some merit after all.
Justice Kimura
June 12
Justice Kimura was born on the 12th of June. Yes, you read that right! Although his name could be read as Masayoshi but can also be read as Justice, which is the case. Born from two police officers they decided this is a name they would give him. He grew to hate it but had second thoughts after Koro-sensei complimented the name and told him it would be a very fitting name to bear– especially once they have succeeded in assassinating Koro-sensei.
Megu Kataoka
June 15
The class representative of class E, Megu Kataoka, celebrates her birthday on the 15th of June. Kind and with great leadership skills, in the past, she had let others take advantage of this and rely on her so much that she forgets to take care of herself.
Despite her ability to put others first, she has a complex about not being feminine enough after repeated comments of her being ‘dashing’ or ikemen.
July
Rinka Hayami
July 12
The girls’ best gunman, Rinka Hayami, celebrates her birthday on the 12th of July. Stoic and business-like, she finds it hard to connect with most of her class, even with Chiba with whom she shares a similar personality.
Despite her portrayal, she has a softer side she just wasn’t willing to show just about anyone.
Nagisa Shiota
July 20
The androgynous assassin prodigy, Nagisa Shiota, celebrates his birthday on July 20.
Born with a mother who wanted a daughter instead, he developed low self-esteem after having been subjected to her insecurity and neurosis. With his time in class, he realized where his talents lie and were able to shake off his mother’s control.
With his low-key presence, quick wit, and unmatched bloodlust he is often referred to as a natural assassin.
August
Touka Yada
August 1
The big sister of class E, Touka Yada, is celebrating her big day on the 1st of August! Beautiful and mature in all sense of the word she is Irina’s top student, citing that negotiation and charm is the ultimate tool when going out into society.
Hating violence, her talent lies in infiltration and negotiation where she has notable skills in bribery and blackmail among other things.
Aguri Yukimura
August 8
Aguri Yukimura, class E’s original homeroom teacher, celebrates her birthday on August 8.
Kind, cheerful, and empathic, she taught the assassin Reaper compassion while they spent time together in the former’s fiance’s underground laboratory.
An accident mortally wounds and eventually takes her life but not before imploring Reaper, who then became known as Koro-sensei, to let go of the life of killing and save people by becoming a teacher instead.
Tadaomi Karasuma
August 15
The tall, dark, and oblivious PE teacher of class E, Tadaomi Karasuma, celebrates his birthday on the 15th of August. Kind but professional to a fault, he trained the class without letting himself get too close to them, realizing too late that he was slowly growing fond of them.
With unrivaled combat skills, it was no surprise that he ended up as a high-ranking officer at the Minister of Defense after his assignment with class E.
Taisei Yoshida
August 19
The mechanic of class E, Taisei Yoshida, celebrates his birthday on the 19th of August. Born into a family of a motorcycle company owner, he is highly interested in automobile engineering and mechanics.
Tomohito Sugino
August 23
The baseball ace, Tomohito Sugino, celebrates his day on August 23. He came into class E after he lost motivation to study after he was removed from the baseball team’s lineup. Together with Koro-sensei, he developed better form and technique and came up with a pitch that enables the ball to change speed.
Rio Nakamura
August 24
The resident trickster of the class, Rio Nakamura, celebrates her birthday on August 24! She has the knack for teasing people and has an almost genius-like ability to find the best target for it. Her ‘cool’ girl appearance and sleazy personality are a complete 180 to her intelligence, being second only to Karma.
Takuya Muramatsu
August 25
The restaurateur of the class, Takuya Muramatsu’s birthday is on the 25th of August. Born to a family that runs a ramen shop, he has excellent cooking skills and a keen sense of smell when it comes to different varieties of food. In class, he is more independent, staging his own plans without the need for others, though he grows to be more cooperative as the year goes by.
September
Akira Takaoka
September 28 [UNOFFICIAL]
People love a good villain and Akira Takaoka, don’t they? Too bad he isn’t. We decided to celebrate his unofficial birthday on the same day as Ask A Stupid Question day because… well how stupid was he to try Nagisa on twice when they were so clearly mismatched the first time? A horrible drill instructor and an even more horrible teacher, he doesn’t deserve to be celebrated but he was pivotal to Karasuma’s realization of just how fond he was of his class and Nagisa’s newfound confidence in assassination so just maybe a small (and begrudging) greeting is in order.
October
Irina Jelavic
October 10
The voluptuous assassin, Irina Jelavic, celebrates her birthday on the 10th of October. Having lost her family and trained as an assassin at a very young age. She only has her seductive assassin persona to go by but after failing to assassinate Koro-sensei and having her cover blown we are presented with her genuine personality: Childish, earnest, and stubborn at times. She connects better with her students and reveals her soft side to them.
Hinano Kurahashi
October 23
October 23rd celebrant Hinano Kurahashi is quite the entrepreneur. From knowing what beetles will sell more to managing ways for parents to pay her to take their children on nature hikes, she certainly has the knack for knowing how she can make a pretty penny. Despite this though, her interests lie in animals and nature in general.
Sosuke Sugaya
October 25
Sosuke Sugaya is the class’s artist and the birthday celebrant on October 25th. Well-meaning and easygoing, he definitely didn’t mind falling into class E where his talents were more appreciated than shunned. Aside from being artistically creative, he showed he was a creative thinker as well when he used ground-up anti-sensei bullets to melt a part of Koro-sensei’s face.
November
Manami Okuda
November 7
November 7’s celebrant, Manami Okuda, is quite the scientist! What she lacks in language skills she makes up for with her skills in the lab, being a very introverted girl she has given up on having her way with words making her seem very straightforward. We see her flourish throughout the year, showcasing not only her talents in chemistry, where she is able to concoct the deadliest of poisons, but also her blooming into a person who can better express herself.
Yuma Isogai
November 13
The princely Yuma Isogai celebrates his birthday on the 13th of November. As the male class representative of the class, he is well respected and well-liked due to his great leadership skills and overall charms. Don’t let this fool you though as he holds the top spot when it comes to knifework.
December
Hiroto Maehara
December 6
The playboy, Hiroto Maehara, celebrates his birthday on the 6th of December.
He has a laid-back personality and ends up just letting things pass, although he seems to be more honest with feelings and tends to react to situations strongly.
He is ranked pretty high up when it comes to knife work, second only to his best friend, Isogai. Coupled with his great agility he simply is one person not to take too lightly.
Kotaro Yanagisawa
December 10
The former Kotaro Yanagisawa celebrates his birthday on December 10. A proud scientist before an accident that cost him his fiancee, he believes it was Koro-sensei who was responsible for his now ruined life and firmly believes he has to die to atone for it. In reality, he was a sadist who saw everyone around him as expendable.
Akabane Karma
December 25
The class genius, Akabane Karma, celebrates his birthday on the 25th of December. Possessing great academic ability, he was able to avoid falling into class E but after trying to defend an upperclassman from the E class by beating up the bully, he was told that he had been too much and would be suspended and demoted to the E section on the next year. He lost all faith in their school system, Koro-sensei proved him wrong and has since become a wonderful addition to the class.
Conclusion
