Koro-sensei Q!

A spin-off of Assassination Classroom (Ansatsu Kyoushitsu). Aired in Japanese cinemas alongside Assassination Classroom the Movie: 365 Days‘ Time (Ansatsu Kyoushitsu Movie: 365-Nichi no Jikan), and later reused as episode 2 of the ONA series Koro-sensei Q! (2016).

Koro-sensei is a teacher for class 3-E of Kunugigaoka Junior High School and the main antihero of Ansatsu Kyoushitsu. He was responsible for carving out a large chunk of the moon to become a permanent crescent moon and plans to destroy the earth after teaching class 3-E for a year.  His name comes from Korosenai (æ®ºã�›ã�ªã�„) means "cannot be killed" and sensei, means teacher. Literally, his name means unkillable teacher.  Koro-sensei is made up of anti-matter. He will inevitably die in March, whether the students assassinate him or not.  It is later revealed that the chance of this happening was less than 1%.  Koro-sensei was previously known as the "God of Death."  Koro-sensei did not actually destroy the moon, a rat infused with anti-matter did.

Koro-sensei

Age: 14-15 Birthday: July 20 Height: 159 cm Weight: 48 kg Abilities: assassination, people reading Favorite subject: English Least favorite subject: science Favorite food: sushi Hobby: researching  He is one of students in Class 3-E. Nagisa is seen as one of the weakest students in the class due to his small stature and mediocre physical abilities that are comparable to some of the girls in the class. However, he is actually the most talented to become an assassin out of all the students, something that acknowledged by Korosensei and Karasuma. He is able to draw closer while hiding his bloodlust to make a surprise attack and able to make his opponents falter through his bloodlust alone.  Nagisa usually writes Korosensei's weaknesses that at first seem minor (since it doesn't look like major weaknesses), but eventually revealed to be useful since once they're able to almost kill Korosensei because of one of his weaknesses that is the same as the one that Nagisa has written down in his note.  Outwardly friendly and polite to his friends and everyone, he hides a somewhat darker side of him as an assassin that won't be able to be found out during daily classes and will only shown during training and assassination time. According to Karasuma, whenever Nagisa unleashes his killing intent, he isn't training and truly goes for a kill.  In the end he is the one who bears the burden of killing Koro-sensei. 

Nagisa Shiota

Age: 14-15 Birthday: December 25 Height: 175 cm Blood type: AB Abilities: assassination, academics Favorite subject: mathematics Least favorite subject: Japanese Favorite food: his own cooking Hobby: provocation, mischief and harassment   Karma is well-known throughout the school for his violent behavior and troublesome attitude. When he was in the main building, due to the betrayal of his most-trusted homeroom teacher, he began to hate all people who called themselves 'teachers' and as a result has almost zero respect for any adults. He is shown to be skilled in fighting, tricky, and manipulative, and takes great pleasure in harming others. He excels at using weaponry and foul play and is one of the few students thus far to have successfully injured Korosensei.  Karma has been described by Karasuma as "at first glance, he comes across as being a lazy sort, but... there's a strong sense of mischief in his eyes." Karma is quite relaxed most of the time as he occasionally skips out on things he finds boring, such as the school assembly. When fighting, he becomes brutal and has no qualms of hurting people who threatens him or any of his friends from Class E.  It is also shown that he is one of the most intelligent people in the entire school, shown to be ranked 4th out of all 186 students in Kunigigaoka. He does not, however, want to return to the main building, stating that he finds assassination much more interesting.  Regardless of his lazy personality, Itona has stated that Karma was probably the strongest within the class despite him not excelling in any particular area (shooting, knifework, etc). Most likely this means that Karma prefers to stick to tricks and pranks for assassinations rather than going into full-out combat, and also because of a certain "vision" Itona described to Terasaka. It has been mentioned by Karasuma, and proven many times, that Karma likes to humiliate his opponent.  Despite all this, Karma actually has good morales behind his motives. The reason he was placed in Class E was because he had rescued a senior from Class E being bullied by students from the main building. He was, unlike his classmates, unprejudiced against them and still considered the senior a 'senpai'.  He's also shown to be hardworking when he wants to by studying diligently after the embarrassing exam arc although he hides it by making it look like he was playing video games.

Irina Jelavić

Birthday: March 3 Height: 159 cm Abilities: assassinations, academics (especially Japanese Literature), playing games  She is a student of Kunugigaoka Junior High School. She is assigned to Class 3-E, where she trains to become a professional assassin, with her teacher as the target.  Yukiko is diligent, ladylike, and cordial; although she does not particularly stand out, she is popular with her classmates. A very considerate individual, she had, on one occasion, volunteered to buy drinks for everyone in her class. Yukiko is deliberative and an excellent organizer. She was responsible for structuring the schedule for Class 3-E's trip to Kyoto, and her work had impressed Korosensei. Furthermore, she is adept in considering all factors before making a decision, which is why she had chosen the virtually unoccupied Gion District as the ideal setting for the assassination to take place.

He is well known amongst militaries for his outstanding reputation and is a powerful individual, which he has proven when he easily overpowered Irina's master, who is a retired professional hitman, and even Korosensei himself is afraid upon seeing his capability for the first time.  He is strict, but kind man, though he keeps a distance between himself and the students due to his status as an agent and his own professionalism. He is one of a few who is very perceptive enough to see Nagisa's talent as an assassin. He seems to know Korosensei's past, though he has no intention to indulge into it further.
