Irina Jelavić

Irina Jelavić is the English teacher of Class 3-E of Kunugigaoka Junior High School and a professional hitwoman hired by the government to assassinate Korosensei.

Personality
As a hitwoman, Irina is a really seductive person. Her flawless acting skills allow her to adopt any personality that might benefit her in her mission. This allows her to execute her targets at point blank. As a killer, she's ruthless and always achieves her objective. Her extreme resilience is one of her most dangerous aspects as a hitwoman, since no matter how many times and ways she has to try, she will ensure her target is dead.

Outside of work, she's shown to be a surprisingly normal, even clumsy person. The luxury lifestyle she lives in as a high class hitwoman made her lose touch with the everyday world. At times, her attitude seems even childish and extremely unprofessional, much to the chagrin of Karasuma.

Her true self, however is extremely insecure and unstable. She has little to no trust on people, and seems afraid of her own feelings. Her traumatic memories from childhood never left her, and thus she didn't grow up properly as a person. She had shut off her feelings completely to be able perform her job properly, and became afraid she might not be able to live that life anymore upon realizing how much she cared and truly felt about the students and especially, about Karasuma.

After the God of Death incident which forced her to confront her traumatic past, Irina has since acted more professionally and much less arrogant than previously. She is more subtle in seducing people with just her facial beauty such as attracting delinquent students to do what she suggests during the school festival. However she is still prone to be mildly immature, for instance giving inappropriate sexual answers in a mock parent-teacher interview (almost causing Megu Kataoka to stab her in rage).

Appearance
Irina is a tall, beautiful young woman. She has long blonde hair, big blue eyes, and fair skin. With an ample bust and a curvy physique, she has a very seductive body that she utilities to seduce and manipulate her assassination targets in order to achieve her goal.

Irina is usually seen in high brands and fashionable clothing which emphasizes her flattering form. This often causes Karasuma to reprimand her for wearing "inappropriate" clothing for a teacher. After the events of the God of Death arc, she switches to a much more conservative apparel, which consists in a turtleneck sweater and a long black skirt.

Despite her life experiences and mature appearance she's revealed to be only 20 years old, much to the surprise of her students.

History
She is a well known hitwoman by the government. She has a proven track record of 11 jobs in countries all around the world. When she was 12, her parents were killed during an ethnic war in her country. After killing the militant who murdered her parents, she wandered in the ruins of her hometown until she was found by Olga. She and Lovro took her in and raised her to become a hitwoman.

Debut appearance: Pro Time
She was first mentioned by Karasuma, when he was on the phone with his boss. Karasuma was worried about the students, because the Government wanted to bring in a real assassin.

She made her official debut in Chapter 8, appearing before Korosensei as a damsel in distress. Some thugs were bothering her and Korosensei saved her. She thanked him and asked where Kunigagaoka Junior High was. Korosensei took her there and she was introduced to the class as their new teacher. The class instantly see her flirtations with Korosensei having a huge effect on him (especially her breasts), the latter fulfilling any of her wishes. When he went to get a Vietnamese coffee from Vietnam though, Irina showed her true personality to the class - cold, ruthless and arrogant. Karma then nicknames her "Bitch-neesan" much to her annoyance and states that Korosensei is not like any target she has come across. Irina brushes it off, and beckons Nagisa any information on Korosensei with a kiss, much to the class's shock. Her first lesson with the class consisted of her reading up on Nagisa's information (one being that he has a keen sense of smell for someone who does not appear to have a nose). Her monologue is interrupted when the class keeps calling her "Bitch-neesan" to her increasing irritation. As a way for them to pronounce her name properly, she makes them to keep practicing the 'v' sound with their mouths for the rest of the lesson, which the students comment to be the "lamest lesson ever".

With her male accomplices, she sets a trap for Korosensei in the shed the next day. When Korosensei returns she asks him for a more private intimate chat in the shed as the class continues their PE lesson. Once inside, she seduces Korosensei to great effect and hides away to supposedly change. At that moment, her accomplices open fire on Korosensei, the gunfire being heard for a short period of time. When the dust settled, Irina comes out of hiding but sees her accomplices lying unconscious and a very much unharmed Korosensei standing before her. The target reveals that he noticed a metallic smell and unfamiliar male body odor at the class since her arrival. Knowing that, he simply played along. Irina is then punished by Korosensei, giving her the grooming treatment (making her groan in an intimate way that embarrasses the eavesdropping students), changed her clothes into a gym outfit and "doing the thing with his tentacles". She groggily walks out summarizing the experience before falling down exhausted.

Afterwards, Irina sits with the class again feeling humiliated and wanting revenge. Tired of coin and learning nothing, Isogai asks her if they could have Korosensei teach them instead. Irina however berates the class for prioritizing their desire to learn for a silly exam instead of saving the world from destruction, and that even if Korosensei is killed, their status as Class E will prevent them from having a meaningful future. She instead proposes that they help her come up with a plan to kill Korosensei and share the reward between them until a student throws an eraser at the blackboard, telling her to "get out". Irina sees the deadly looks of the students before ducking for cover as the class riots for her "bitching".

In the study room, Irina complains to Karasuma of having to teach instead of killing. Karasuma takes her outside and sees Korosensei coming up with individual tests for the class. When she sees and listens how much Korosensei has given purpose to the lives of his students, she begins having second thoughts about them. In the next class, Irina starts giving an example of her assassination experiences, talking about how language plays an important role in any assassination. She also apologizes for being a bitch earlier, which the class accepts. However they still call her Bitch-sensei, much to her chagrin.

Settling In
Irina makes minor appearances since. When the whole school assembles, she joins in and attracts most of the male students' attention for her appearance, though somewhat dampens this when she attempts to extract more information from Nagisa (nearly smothering him with her breasts) and trying to strike Korosensei. During the mid-terms arc, she reveals that she always made backup plans for assassinations should her original plan go wrong in the slightest at Korosensei's inquiry. At the time, Korosensei wanted the students to realize that they still need to plan ahead for the future should their teacher's assassination is successful and the reward money is claimed. At the school trip to Kyoto, she is berated by Karasuma for not dressing properly as a teacher, leaving her depressed and the students to comment that perhaps living the high life as an assassin made her out of touch of knowing a normal life. However she socializes with the female students on the last night of the trip, which was ruined by a peeping and eavesdropping Korosensei.

Master and Student
Irina continues to settle down as a teacher, continuing to impart the knowledge of language and art of conversations to Class E. After one such class ends, she is exhausted but still complains about Korosensei's fetish for her breasts. Leaving the staff room, she is suddenly strung up by an assailant. Freeing herself, her attacker reveals itself to her mentor Lovro, a retired assassin known for training children to kill. He comes to take Irina off the mission, considering her to have compromised her undercover status in teaching the students and killing Korosensei. Irina begs to be allowed to stay until Korosensei intervenes. He proposes that the two attempt a mock assassination of Karasuma for Irina to prove her worth, which all individuals agree to.

Her first attempt was humiliatingly unsuccessful, with Karasuma and even the students knowing that the drink she was carrying for him was drugged. Knowing that Lovro could strike any time, she is surprised to witness him attempt a frontal assault on Karasuma in the staff room, though this too was unsuccessful. Karasuma also demands her to get serious if she wants to win, scaring her (and Korosensei) in the process. Irina does try again, this time luring him with the art of conversation and "to get this over with". She surprises him when she makes him lose his balance before pinning him down. Her attempt to stab him with a fake knife though is intercepted by Karasuma. Knowing that he would win if it came to a contest of strength, she requests him to relent with puppy dog eyes. While not at all impressed by this, he does so and gives her the win. The whole thing was seen by Lovro, who realizes how dedicated she is to her work as an assassin and teacher thanks to Korosensei. With this, Lovro allows Irina to stay, much to her joy and relief.

Assassination Island Arc
Irina plays a minor role during the Assassination Island arc. She does not actively participate in the class's training for their upcoming assassination attempt, only hastily joining in when her mentor Lovro arrives as a special instructor. On arrival at Okinawa she is furious that no one is at the island to witness her debut swimwear due to the class booking out the entire hotel. However she reiterates to Karasuma that the students' plan is sure to fail, and that she will step in to do the deed at that moment.

While the class's plan does fail, an unknown third party has masterminded the poisoning of ten of the students. Irina joins the healthy students, Karasuma and an immobile Korosensei in infiltrating the mountaintop hotel where their new enemy is staying, Irina needing Karasuma to assist her due to being unable to climb the cliff face. Reaching the main lobby full of guards, Irina walks in acting tipsy, and distracts the guards with her mesmerizing performance at the piano. This allows the rest of the class to slip by unnoticed, and appreciate their teacher's talents despite her bitchy behavior. After learning of their successful mission, she makes her own way back to the class's hotel.

Prior to leaving the island, the class notice Irina's attempt to seduce an ignorant Karasuma. They decide to help her act a little more mature and arrange a dinner date with Karasuma to better notice her. Irina appreciates the class's assistance but ruins the critical moment when she talks about her first kill with Karasuma. Flustered, she leaves the table and blames the class for her mistake.

The God of Death incident
Irina returns to the spotlight in the God of Death arc. During the lead-in, she is disappointed that Karasuma forgot her birthday and thus did not receive a present from him. The class keeps her company while simultaneously arranges for Karasuma to present her with a bouquet of flowers. However when he admits that he considers their relationship to be purely professional and only because of their mission to kill Korosensei, Irina discovers the class's involvement and leaves the classroom, seeing that staying in the classroom will cause her skills and worth to deteriorate. She does not return for three days until the man the students bought the flowers from arrives at their classroom. He reveals that he is the God of Death, has kidnapped Irina and is holding her for ransom at a secluded warehouse.

The class conduct a rescue mission to save Irina. However they discover too late that Irina has joined the God of Death and betrays them, taking out Kataoka's rescue team single-handedly. When Korosensei and Karasuma arrive at the warehouse, Irina plays hostage and successfully baits Korosensei into a pitfall trap, dropping him in with the imprisoned students. Both the class and Karasuma are horrified to learn that Irina went along with the hit man's plan to kill Korosensei despite knowing the students will be killed as well, Irina simply stating as long as her mission is complete. When Karasuma heads off to stop the God of Death, Irina stayed behind to watch the prisoners and told them why she switched sides - that he knew what it was like to grow up in a war-torn country and needing to kill to survive. Irina later catches up to Karasuma from behind, grazing his cheek with a gunshot but gets buried under the collapsed ceiling caused by the God of Death's trap. Regaining consciousness, she finds Karasuma rescuing her at the insistence of the students who have been sympathetic to her past. Karasuma tears a sleeve to wrap her broken arm though she gets a nosebleed at the sight of his muscled body. Realizing that the students do indeed care about her and that the God of Death only used her as a pawn, she betrays him to allow Karasuma to gain the upper hand, and witnesses the latter's victory. The majority of the class forgives Irina's betrayal though a few still wanted to dish some payback.

After the incident, Irina rejoins the class faculty and reconsiders her stance in the class.

Later Appearances
As winter approaches, Irina has since appeared periodically in later arcs. When Korosensei holds a careers consultation, Irina arrives at the class with a more conservative, less revealing style. The students notice the sweater she recently bought still had the size label, which Nagisa removes without her noticing. When Nagisa's mother is set to visit the school to request Nagisa be transferred back to the main campus, the class scramble to disguise Korosensei as Karasuma who was away on a business trip. Irina volunteers to be the teacher but under a mock interview session, her answers prove that she is still immature (almost causing Kataoka to stab her in anger).

During the school festival, Irina attracted the attention of the same delinquent students responsible for kidnapping Kayano and Kanzaki at the school trip. She is seen to continually seduce them in coming back to the mountain classroom to help Class 3-E raise more money. At the end of the semester, she witnesses Kayano's true identity and her near-suicidal attempt on Korosensei's life. Although unable to come up with an idea to distract Kayano's bloodlust, she sees with some satisfaction Nagisa's seduction kiss on Kayano. Irina praises Nagisa's kiss, but comments that he still has a long way to go to match hers. She later listens to Korosensei talk about his past life as the original God of Death and how he was influenced to become a teacher while in captivity.

Final Semester
Irina arrives with Karasuma and Korosensei after a fight breaks out between Nagisa and Karma. She later watches with Korosensei a paintball battle between the red (kill) and blue (save) teams from a raised platform and comments how they, as teachers, managed to raise some talented assassins. Moreover that some like Kanzaki and Karma had been hiding their talons until this moment.

Abilities
Infiltration: As an infiltration assassin, Irina is considered second to none. She is able to charm her way into her target's inner circles, penetrating the highest security and killing them when they're alone at point-blank range with little difficulty. Irina is seen to be able to adopt different personalities in order to infiltrate into the various situations her missions put her through.

Planning: After her seduction techniques, this is considered to be one of her greatest talents. She elaborates detailed plans completely on her own, with backups for any complication that might arise, thus giving her target no chance of survival.

Linguistics: Irina is extremely skilled in conversational abilities, being fluent in 10 different languages. Through these skills combined with her infiltration abilities, Irina is able to extract information from her targets.

Martial Arts Competence/Weaponry Master: Being an assassin, Irina shows considerable expertise when handling weapons such as firearms and melee weapons. She's also shown her abilities when setting up complex trigger traps when attempting to kill Korosensei. She is shown to be skilled in martial arts but since she's an assassin and not a combatant, she's severely under-skilled when compared to more prominent fighters in the series, such as Karasuma.

Other Abilities: Irina has been shown to be able to play the piano at a concert-performer level with ease while still being able to draw people's attention through minuscule body movements. She is also an expert negotiator.

Korosensei
Korosensei is her target. Most of the time, Irina tries to attack Korosensei, who easily evades her attacks. They seem to have a friendly relationship, even with Korosensei constantly making fun of her assassination attempts on him, and, especially, her love life.

Tadaomi Karasuma
At first, Irina had little interest in him and found him a pain to deal with. Their relationship also started off on the wrong foot as her failed attempt in ending Korosensei's life and lack of interest in teaching the students nearly led to her early dismissal. However, as time passed, their relationship turned more cordial as Irina took an interest in the students well-being. Eventually, Irina was revealed to have genuinely fallen in love with Karasuma through her failed attempts at seducing him.

Lovro
Irina was Lovro's disciple and to this day, she still has the upmost respect for him. As revealed in a flashback, Lovro and Olga found her among the ruins of her hometown, and after seeing her potential as hitwoman,took her under their wing and raised her into the person she is today.

Toka Yada
Out of all the Class 3-E students, Yada is Irina's favourite. Yada had been the most interested in learning the art of infiltration and negotiation from Irina, and sees them as her "second blade" in later life. As a result she, along with Hinano Kurahashi, truly knows of Irina's past, and is among the first to vouch for her in convincing Karasuma to save her life during the God of Death arc despite her earlier betrayal. The class see Irina and Yada become a formidable pair at the school festival, Yada utilizing her negotiation skills to advertise and convince customers to travel the mountain path to their makeshift restaurant, and Irina subtly seducing them to stay. Although taught how to seduce her target, Yada prefers not to use it as a means to get the desired outcomes.
