As I've promised, I'll try to not make Y/N an outsider anymore. This is quite a hard time, considering her (your, whateva) approach is at the same time, Karma's and lots more. So as usual, I'll try my best! Wait for me!
Beware of cursing words.

Kiritsu!Rei!Lock on! 

——————\_( '-')_/——————
  "Oh? Long time no see, Big Teach." Inside a mart, Koro-sensei, disguised as a normal human (although of course he failed, considering his large body and height, and the fact that his "hand" has only two fingers), was paying for his groceries and snacks. The sales assistant seemed to know him, because that was his greeting, plus a close-eyed grin. "Yes, payday's come at last." The disguised teacher replied. Walking out of the mart by his concealed-by-oversized-black-traditional-Japanese-pants tentacles with a bag on his arm, he stated. "Japanese cheap snacks are of superb quality. More than the worth of disguising myself, I'd say."
"やめて下さい！(Stop please!)" a woman's voice rang out near him. He looked up, only to see a beautiful blonde with white office vest and white working skirt being pushed over to a car by some bulky men.
"Aw, just come with us, will ya?" The man on the right of her with a fancy red vest said as he leaned closer.
"But I have to get to my new teaching job!" The blonde protested, her hands wrapped around her breasts protectively.
"So you are a teacher?" Another man wearing a blue back-faced cap smirked, his small eyes and big nose all screamed pervert.
"Hey," another with a tattoo on his left eye pointed to himself. He might be mistaken for a large bulky highschooler for his campus jacket and jeans, if not for the punk yellow hair (being the only clump of hair, that is) on top of his head. "We could use a little tutoring ourselves."
"How about a crash course in picking up women from your car?" The still disguised teacher appeared behind them. His "hands" grabbed their collars and threw them into their car, slamming it close in the process.
"Lesson 1: It is vital to decorate your car beautifully." He declared as he pulled out a large pink ribbon out of nowhere. "Wriggly wrapping!" Using Mach speed, he quickly wrapped the car into something like a present with a ribbon rose and a cute bow. "The car is completely covered in ribbons!" The perverts inside the car exclaimed as they hadn't yet overcame their shock.
"There is no lesson 2." The teacher finished. His childish voice became lower and more gentleman-like as he appeared in front of the scared teacher. "Are you alright?"
"Thank you so much!" The blonde exclaimed as she ran to him and snuggled herself into his clothes. "I thought chivalries weren't here anymore!" (FYI, chivalry means knight, so in here she means that she thought chivalries were dead, but actually one is still here and that is Koro-sensei. Such a flirt.)
"I will never forget your kindness!"
Her beautiful topaz blue eyes looked shyly into his beady ones and her cheeks were dusted with a rosy color. Her pink lips opened again as she smiled at her savior. "By the way, do you happen to know how to get to Kunigigaoka Junior High?"
———Class 3-E, Kunugigaoka Junior High - Old Campus———
"Now, allow me to introduce your new English teacher." Karasuma's serious voice declared.
"My name is Irina Jelavic, it's wonderful to meet you all!" The blonde who kept clinging to Koro-sensei's arm said her greeting with a happy smile, pink hearts literally appeared to illustrate her admiration and love towards their home room teacher.
  "What a knockout!" The students in class sighed. They could never imagine their teacher to be as easily charmed as that. They thought he would be a bit tougher! "What knockers!" Okajima exclaimed.
Why's she all over him?
  "Who'd thought you were a teacher here?" Koro-sensei said as his "hand" moved upwards. "I'm wearing a wig."
  "Oh, I don't mind!"
  "I hate her already." You murmured, she is all TOO suspicious.
  "One of our school goals is to give you authentic experience in foreign languages." Karasuma looked at Koro-sensei who looked back. "I trust there'll be no objections to her taking over half of your English lessons?"
  "Well, if you insist."
  "We've got us one heck of a teacher!" Kaede smiled helplessly. "What's more, she seems to have a thing for Koro-sensei."
"Uh." Nagisa nodded. "I might get some assassination ideas from this." He took out his notebook. "I think he would not know what to do with a human woman hanging all over him." His face has so many unique colors, his pen was ready to jot down new things, I wonder what the color of bewilderment is.
Just then, their teacher grinned wilder if possible, and his face became pink with cherry red bloomed on his cheeks. A soft pink light emitted from his face, and he looked oddly satisfied.
  "He's just plain smitten!" The students sweat-dropped. "I guess he's fine with human too, then." Nagisa remarked while noting down.
Koro-sensei's weak point #5: Breasts
"Ah," their new teacher named Irina kept clinging onto Koro-sensei's tentacle. "The more I look at you, the more I like what I see." She continued to flirt with him. "Your beady eyes, like two diarrhea pills..." said beady eyes blinked. "Your strange, flopping limbs..."
Don't fall for her traps! Hinata darkened her face as she secretly want the teacher to realize that the new teacher is nothing good. No woman likes those thing, I tell ya! Nakamura clenched her teeth, agreeing to the brunette in front of her.
We're not that dense. Any teacher who joins us under these circumstances... have more than meets the eye.
——————————————Outside, PE——————————————
  "Hup! Pass! Hup! Kill!" The class chanted as they played a ball game with the ball that has the decoration of Koro-sensei's normal face.
  "I had all kinds of ways to approach him prepared." Said Irina as she and Karasuma stood watching them from inside the campus building. "I just never thought seduction would work." She flicked up the lid of a cigarette case, used her mouth to pick up one, and lit it with a pink cigarette lighter.
Irina Jelavic, professional assassin. Karasuma went though her information in his head while glancing at the blonde woman. With her drop-dead gorgeous looks and fluency in 10 languages, she can bewitch targets from anywhere in the world, and eliminate even the most heavily guarded marks from point-blank range with ease. Her fitness at infiltration and approach has raised her assassinations to an art form.

  "However, we can't hire an assassin to work at school." Karasuma thought out loud, as his companion walked away, noticing a girl who sat at the back of the class, not participating in the game. "You will need to do some teaching for the sake of appearance."
  "Ha..." The blonde sighed, closed her eyes as she quirked her lips gently and opened the classroom door. "I am a pro." She opened her eyes and looked directly at him with a confident look, topaz eyes held somewhat a mocking and underestimate attitude. "I'll get all things done before it comes to that." She walked in.
  "Hi there." (Y/N) said with a bored face, right after she set foot in the classroom. You were sticking to your "no killing" rule and didn't take part in any games with killing included. "Nice to meet yo-"
  You were cut by a pair of lips on yours, and for several seconds the famous assassin held on. Your mind went blank, and after what seemed like a century she stopped and let you go.
  "Just so you know, people don't greet by kissing on the lips, especially when we are not a couple." You said as your brows furrowed and your arm went up immediately to cover your mouth and trying to wipe away the feel of having your first kiss stolen by a woman, and one you hate at that.
  "Why do I care about that?" Irina curled one of her locks and sat on your table. "What I care about, is some information on the octopus." She said with a wink but her eyes were fixed on you.
  "I came here not so long before you, so you've asked the wrong person. Now go away and ask somebody else who stayed here for long enough." After a while, you seemed to rethink and added more politely. "Not trying to be rude."
  She seemed to take your idea right. "So do you know - answer me honestly this time or get another kiss, French-styled - anyone who might have information?"
  "No. But I think Nagisa should be the one. He's into analyzing and such." You sighed.

 "Full name?" Irina fiddled with her nails.

  "Shiota Nagisa." Nagisa, I apologize if you got the same treat.
"Good girl." She looked at you with fake affection and the whole "my charming still works" was written on her face.
You raised your brow a little before opening the book again and read. "Now go away and if possible, bring your disgusting French-style of a kiss that you gave me please. I'd like to have my first kiss back."
  She just smirked and confidently stroke out of the classroom. She's up to no good. You thought and closed your book once again, not even reading a word as you bookmarked it and got out of the classroom, into the open of the P.E field.
You didn't see the blonde teacher, but a crowd who huddled together, so you ran there.
  "What happened?" You asked. Isogai gestured to the middle. "You should see it yourself."
  As you got to the middle, you saw that indeed, Nagisa was being kissed on the lips by Irina. I apologize.
  After the long kiss, Nagisa fell down and covered his mouth just like what you did. "Come to the staff room later." She murmured to him and waved towards the students. "The same goes for anyone else who had key intel!" She looked around and smirked. "I'll give you something good in return. If you girls prefer, you can have one of my men instead." She turned to her gang who had just turned up, two of them had gun cases on their shoulder. "It's a pro's job to have both technique and connections. You brats go watch from the outfield." Three men stood behind her, there dark colored suit made her stand out more in her white suit and blonde hair. "Oh and one more thing, if you interfere even slightly with my assassination," she held a golden pistol up so that it touched her mouth, "I won't hesitate to kill you."
  Tough-looking companions, and a threat delivered with unfaltering determination, we knew at once she was the real deal: a professional killer. Nagisa looked at her direction, not yet overcame from the shock. But at the same time, most of the class also knew something else: that they hate her.
  "Let's just...get to class. What's the next period?" You asked as you helped Nagisa to stand. "English, by Miss Bitch." Karma smirked annoyedly as he walked towards you two. "Well that's boring." You rolled your eyes. "Nagisa, how was the kiss?" Karma asked as his mischief surfaced. "A-ah..." Nagisa immediately blushed. "Her kisses are strong enough to make you swoon..."
  "And when she kiss you, your mind went blank and she stole your first kiss. I know, right?" You continued. "Wait, how did you-"
  Nagisa was surprised. You pointed to your own lips. "That's how she greets me, a twenty-hits French-styled kiss. Karma, no, I'd like to forget this and get on with my life, pretending that 'that bitch' hadn't stolen my first kiss." Karma just laughed.
———————English period———————
  The tension continued as the students stayed silent while their so-called teacher was busy settling things on her pad, after writing two big words "Study Hall" on the board.
  I've never killed an unidentified creature before. Irina thought and tried to set the most effective trap with the campus blueprint she was given. Everything's ready. She turned to a certain boy with pigtails, and winked, licking her lips. Nagisa had shivers up and down seeing that.
————————Flashback——————
  Nagisa came to the staff room just as told. And then he got kabedon-ed to the board by the new blonde teacher. (A/N: Kabedon is the action of pinning a person with one of your hands beside their shoulder as their back faces the wall/fence - anything that's flat and tall enough - usually to show that you can overpower them or will be kissing them [in some ways],the people who do this are usually males) Nagisa took out his notes and began to read for her. "Some of us has destroyed a single tentacle, but it doesn't faze him. It's possible that you might have to destroy all of his tentacles at once." He wearily looked up at her. "He can easily escape before you finish him off. Thus,..." he stopped hesitantly for a fraction of second, " if you want to sneak up on him, you probably shouldn't smoke." Irina lifted her head up, surprised. "For someone with no nose, he has a keen sense of smell." The blue-haired boy explained, remembered the time he and Sugino were caught eating chocolate bamboo-shoot cookies by none other than the supposed-to-have-no-nose mouth-watered Koro-sensei.

  That shouldn't be a problem for me. Irina smirked confidently while the class stared helplessly at her and sighed. After all, I'm Irina Jelavich, a pro among pros, who's pulled off  assassinations in all kinds of circumstances. Until Maehara decided to stab her back to reality, in a painful way.

  "Ne, Bitch - neesan, are you goin' to teach us or what?" the "Bitch" part really stabbed her and made her stumble back in her chair whose back rail was on her right side, so she nearly fell (she sat on the side, back-facing the floor instead of the rail). Another decided to rub salt in her already deep wound of pride. "He's right, Bitch - neesan!" Sousuke just made it worse. "I mean, you are a teacher, right Bitch - neesan?" and she couldn't take it anymore.

  The pro assassin snapped. "Argh, quit your 'bitch'-ing!" These brats couldn't even spell her name right! Especially the '-vic' part! "For one thing, they're pronounced differently! Your Japanese just can't differentiate between the 'B' and the 'V'! I'll teach you the correct way to spell 'V'. First, bite your bottom lip." She encouraged a bit too demandingly. "Go on!"

  When the class did just that, she lifted her head and grinned. "Right, just like that. Now stay like that for an hour and give me some peace and quiet."

  What kind of lesson is this! The class angrily thought out loud with their temporary sealed mouth.

  ———————Recess time———————

  "I understand that you've brought in a rather shady trio." Karasuma encountered the blonde assassin on the side of the building. "I wasn't informed of this." He crossed his arms.

  "Yes: all pros are more than competent, not to mention tight-lipped." She reciprocated, her hands on her hips. "They are so in love with me that they'd do anything I ask. For free." Her voice leaked confidence as she wore her signature smirk. "Everything is set up." Her brows furrowed and she looked smug but determined. "Today I act."

BANG!

  The sound of something comet-like crashed the campus ground, sending dirt everywhere. "Irina - sensei!" The culprit, Koro-sensei, walked up to the two teachers with a cup of tea which is surprisingly still in one piece and fresh from all the dirt and flying earlier. "Here's the Indian chai that you wished for." 

Irina's innocent acts quickly went up. "Oh thank you, Koro-sensei! Just what I want for afternoon tea!" She clasped her hands together to make her words more convincing, and ran towards the octopus in a childish way with her forearm up, hands slightly clenched into fists and were flailing on her forearms from the way she ran.

  "Actually, I want to speak with you, Koro-sensei." She looked up at him and fake smiled. "Could you come to the shed during the fifth period?" She asked gently and innocently.

  "Speak with me? Why of course." The teacher replied pleasantly with his cheeks a tint of red. He quickly changed to pink. "Fifth period, right?" He scratched his head while Irina chuckled. "I'll be there with certain-tea! It's chai tea, get it?" (that's an Indian tea pun, I don't know much) Karasuma looked at them with a serious manner from the shade.

—————Fifth Period - PE —————

  Again, you are still sitting at the back of the class when two silhouettes caught your eyes. Weird, you thought, the students are still in the foreground practicing shooting. They shouldn't have sneaked here, Karasuma - san would notice. 

  Upon turning back, you figured out that it was Ms Irina - or rather, Ms Bitch - and Koro-sensei. Ms Bitch was walking with a smirk on her lips and the yellow-turned-pink octopus went with her to the basement behind the classroom building. 

  "Wait!" you shouted and tried to gain Koro-sensei's attention by banging on the windows. "Don't go!"

  The teacher saw you but instead, he waved his tentacle, "it's fine. (L/N)-chan, why don't you go and practice your aim with the class instead? You would become a fine assassin, should you be practicing and progressing with them." His cheeks turned rosy and his head glowed, "I need to meet up with Irina-sensei at the basement."

  "Stop! You can't go there!"

  He ignored you and continued his daydreaming. Ms Bitch glared at you, blue eyes burned with hatred, as if saying You're next when I'm done with him. 

  You should be able to run towards them, but at that time it might be too late. Interfering might be needed, but you decided to just let nature take its course and see what would happen. That octopus, what is really on his mind? Is he really that dumb or does he have something up his sleeves?

  "My trip to India was perfect chai(time)-ming, was it?" the octopus was talking, not aware of his students' trying to get him come back.

  "Karasuma-sensei," Kataoka said as she watched the two of the teachers' back disappearing in the shed, "I don't think we'll ever warm up to her."

  "Sorry about that." Karasuma crossed his arms, " she was hired on government order. Still, being able to complete all her preparations in a single day proves she's an assassin of the highest calibre."

  ------------------------ WARNING: SLIGHTLY INAPPROPRIATE SCENE. SKIP TO THIS SAME LINE IF YOU DON'T WANT TO BLEACH YOUR BRAIN. I KNOW YOU MIGHT BE UNDERAGE. (cuz I am, but I need to write) ----------------------

  "So, what did you want to talk about, Irina-sensei?" Koro-sensei turned back as Irina closed the door behind her.

  Assassination by infiltration requires flexibility towards one's target. Irina just put on another act and smiled. She turned to Koro-sensei and slowly took off her white coat. I'm up against an unidentified life-form. Best to do it quickly, before he gets suspicious.

  "Koro-sensei." She called his name seductively and brought forward her most innocent act. "I-I always fall head over heels for exceptional people." She approached the teacher slowly, her breasts against his chest while Koro-sensei had a short panic.

  "With your body, your strength, it was love at first sight." Irina continued to say sweet nothings while seducing the already pink octopus. He stuttered while waving his tentacles around frantically. "Do you think that's strange of me?" Irina asked him with sickly sweet voice.

  I need to be as forceful as necessary to distract him so that he won't notice what's really going on. Irina feigned innocence while showing off her generous breasts. I spent all night fixing up the place. All to hunt you down, target of mine.

"You're such a bad boy, Koro-sensei." Said Irina, still with breasts propped up against the fabric of the other's clothing. "We can't do this! Not here!" Said sensei was still in his panic mode. You foolish, foolish man.

  Farewell.

  -----------PLEASE CONTINUE READING AT THIS  LINE IF YOU HAD SKIPPED. YOU NOW NEED CLOSE TO NO BLEACH TO WASH YOUR EYES.-----------

  "Give me a minute to take this all off." Irina raised herself up from her leaning position which shocked Koro-sensei even more. "ALL?!?"

  "Relax," she smiled at him. "It'd be over before you know it." was the last sentence before she disappeared behind the old wooden chalkboard. 

  "All..." was his last word before being shot by a violent dance of bullets and gunfires.

  Real guns and live ammo. Irina analyses the situation in her blonde head while desperately preventing her ears from bleeding from all the noises. An M61. A six-barrel, air-cooled, electrically fired Gatling-style rotary cannon came into view, empty bullet cases raining down the ground. An M134. Another six-barrel military cannon with an incredible capability to fire 2000 - 6000 rounds per minute took part in the dance, bullets flying with bright rays of light. An an M249. A surprisingly small gun compared to his companions, lean and light with the affective range up to 700m (2300ft). All are spraying ammo with superlative speed and firepower. Irina Jeravic's lips pulled up to a light smirk, cerulean blue orbs glinted with glee and lightened by the aggressive beauty of gunfire. Those weird pellets won't be necessary. 

After all, there's nothing that this barrage of bullets couldn't kill.  

Firing sequence complete in three, she counted and crouched, two, her eyes sharp with cruelty, one. 

  All the noises stopped. Irina walked out from the wooden board. Zer-

  She paused, looking at the scariest thing to walk in on, suddenly feeling small.

  He was still standing. With eyes shining as lasers and smoke billowing from his supposed "hands".

  "I regret to inform you that lead bullets are useless against me, Irina-sensei." He said and opened his hands. "They simply melt against my body." Lead and melted iron poured out from the outstretched tentacles.

  "Now, take a good look at my face." He said, his tone still polite and respectful despite her attempt earlier. Irina gasped. "You have...four eyes?" two pairs of small round "eyes" met hers.

  "No, two of them are nostrils." The yellow octopus simply and innocently stated. "They look the same!"

  "There's a metallic odor in the shed that wasn't there until yesterday. An old-man smell whose incongruity opened my nostrils." This made Irina gasped in recognition.

  For having no nose, he has a keen sense of smell. Nagisa had revealed to her while pinned to the wall.

  "By pretending to be caught in your trap, I could easily uncover my assassin. In other words..." the creature's eyes shone red. "As a pro, you clung too tightly to common-sense assassination. My student's attempts are far more flexible and formidable. And did you know?" He said while walking towards her, who continued to go backwards until her back hit the wooden wall. "My retaliation takes the form of care and grooming."

  "NOOOOOOOOOO!"

  The scream made the students outside tense up. "What was that?!" "Gunshots, a scream... and now a slithery sound!"

  "Guess who survives." You sighed inside the class as the slithery noises and squeaking sounds turning softer can be heard from behind, inside the shed.

  "She's getting slithered for good!" Okajima the perv said while Maehera urged others to go and see.

  Class 3-E ran up towards the shed with you walking behind. Once there, they saw the Koro-sensei, pink all over, slided the door and walked out.

  "How are those boobs?!" The same perv asked.

  "I wish I could have enjoyed myself a little longer..." The teacher replied with even more pink dusting his face before turning to his default yellow. "But I'm really looking forward to our classes together."

  "Wh-What happened in there?" Nagisa asked, uncertain to get an answer. At that exact moment, Irina walked out, looking dreamy and tired altogether. "Ah, Bitch-sensei is wearing a wholesome, retro gym outfit!" 

  Indeed, she was wearing the gym outfit for females, with her name tag on her white shirt and a red ribbon on her head, hair tied into a curly ponytail.

  "To think he did that to me in only one minute... he loosened my stiff shoulders and back, gave me a lymphatic oil massage, got me changed at top speed, and then to do that slithery thing with his tentacles?" She mumbled and collapsed face first to the ground while all students sweat-dropped. What thing?!

  You turned to Koro-sensei who had then stood behind the class. "What did you do, Koro-sensei?"

  His face turned white and thinking (?). "Oh, y'know, grown ups need grown-up care ._."

  "That face isn't innocent!" He ignored the comment.

  "Let's get back to the classroom." "Yes sir."

  Behind them, Irina had found her strength to get up. "Unforgiveable. I've never suffered such an unsightly failure!" She pulled the red ribbon from her hair, which fell down to place. Her topaz eyes narrowed in anger and hatred. "I am a pro, and I shall seek revenge for this disgrace!"

  Back at class 3-E, it was once again "Study Hall" and the class was seriously getting bored while their teacher was busying herself with her red tablet furiously. That octopus better not think a pro like me is already out of ideas. I'll need all-new supplies. She thought with clenched teeth as she browsed through all the men list. "Darn it, why doesn't this backwoods school have Wi-Fi?!"

  "You're trying awfully hard, Bitch-sensei." Karma said in a light mocking tone. "Your pride must be in tatters after that."

  "Excuse me." Isogai said and she immediately snapped at him. "What?!"

  "I really think we could use some proper learning, Bitch-neesan." You stated as Isogai worriedly added. "If you won't teach us, could you swap with Koro-sensei? We've got entrance exams this year."

  "Ha!" Said teacher laughed. "You want that vicious creature to teach you? You think your exams matter that much to a planetary crisis? Must be nice being a clueless kid!" She stood up and smirked with hands on her hips. "Besides, I understand you E-Class students are the school's loser misfits." The statement made the class tense up and the atmosphere quickly turned hostile. "There can't be any point to studying now."

  "I know... How about this? If my attempt succeeds, I'll give you 5 million yen to share! That's far more than you'd gain from any pointless schoolwork! So shut up and do as I-"

  "If you persist on not teaching, get out." You threw your eraser right next to the cocky teacher's face, which collided with the board and made a sound that rang through the silence.

  She stopped mid-sentence as she realized her current situation, hated whole-heartedly by the whole class. The eraser seemed to add fuel to the fire as the class yelled "get out", "bring in Koro-sensei" and throw stuffs at her.

  "Wh-Where'd all this come from?! I kill you all!" Irina desperately said while covering herself from the outburst.

  "I'd like to see you try!" They only become more angered.

  "Right, right! Down with big boobs!" Kayano yelled with her "flat is justice" made-up poster. "That's your complain?!" Nagisa who was covering his ears yelled back. Karasuma outside just face-palmed.

  "What's with those brats?!" The strenght was enough to knock the Staff Room's board down. "They are sharing space with a fine woman like me... and they're not grateful?!" Irina released her anger on the poor desk while Karasuma just typed and typed. "They are not...hence the classroom chaos." he simply said. "Go apologize to them... if you want to stick around for another attempt, that is."

  "Why should I? I have no teaching experience!" She demanded in frustration. "Let me focus on assassination!"

  The male just sighed. "Alright then. Come with me."

----------------------------------------------------

  "Erromango, one of the islands of Vanuatu, or the New Hebrides..." Koro-sensei was mumbling as he used various tentacles to sketch and write.

  "What's he doing?" Behind the trees next to the clearing stood Irina and Karasuma. "Writing test questions." Karasuma replied. "It's what he does every Wednesday during sixth period."

  "It sure seems to be taking a long time." Irina commented while folding her arms up. "At Mach 20, shouldn't those tests be written already?"

  "They're different for each student."

  "Eh?"

  "He writes individualized questions, taking into account the student's best and worst subjects." 

  While they were having a quiet conversation, the yellow teacher continued murmuring. "Chiba has spatial figures down pat. Why don't I give him a slightly tougher and tricky question?"

  As the blonde stared in awe, the tall male continued behind their hiding spot. "He has advanced intelligence and speed, this dangerous creature who'll destroy Earth. And his teaching work is close to perfect."

-----------------------------------

  "Now look at the students." Karasuma said as the class is having a ball game in the campus ground.

  "Oh? They're just fooling round."

  "It's training how to accurately strike a moving target with a knife." On a closer look, each students were holding a wooden blunt knife, continuously hitting on the ball which was painted yellow with Koro-sensei's face. "Assassination badminton. I taught them that."

  "What?" 

   "Target and teacher, assassins and students. Here in this bizarre classroom that creature's made for us, everyone has two roles to play." He turned his gaze to the blonde. "You make a big deal out of being a pro, but if you can't be both an assassin and a teacher," he started walking away. "Then this is the worst place for a pro like you."

  "If you want to stay here and keep going after him, don't look down on these students."

-------------------------------------------------------------------------------

  The class was chatting as the door opened, and Irina walked inside. The air almost immediately became tense, but she ignored that, picking up a stray chalk, and started to write.

 "'You're incredible in bed.' Repeat." Her words surprised everyone as they stayed silent. "Come on!"

  "Y-You are incredible in bed."

  "When I assassinated a certain VIP in America, I first turn on the charm to get close to his bodyguard. Those are the words he said to me. They mean: 'You are great in the sack.'"

  Just what are you making us junior-high kids say?! Nagisa thought as his face lid up.

  "It's often said that the fastest way to learn another language, is to get yourself a lover who speaks it. You want to know what they are feeling, so you try your hardest to understand what they say." She explained. "When necessary on the course of work, I have used that method to learn more than a few new languages. Therefore, my lessons will teach you how to sweet-talk foreigners. The basics of chummy chats, straight from a pro assassin: Master them and they'll come in handy with a real life foreigner."

  A foreigner! Nakamura and Okajima daydreamt.

  "Let that octopus teach you what you need for your exams. the only thing I can teach you is practical conversation skills." Irina looked away and pressed her hands together. "And if you still don't think of me as a teacher, I'll give up on my assassination and leave. Th-That ought to fly with you all." She stuttered. "And... I'm sorry about all that stuff."

  The class stared at each other, then laughed out. "Why so nervous?" said Karma, amused. "You were just threatening to kill us!"

  "She's totally a teacher now." Maehara smiled.

  "We can't call you Bitch-neesan anymore." Yoshida happily said.

  "You...you understand!" Irina covered her mouth and gasped while the students chattered on. "It was a pretty rude thing to call a teacher." "Yeah. We need something else to call her."

  "How 'bout Bitch-sensei?" made her relief shattered to absolute pieces.

  "Etou... How about we move away from the whole 'bitch' thing? Just call me by my first name, I won't mi-"

  "But that 'bitch' thing really isn't going away." Maehara interrupted and Yoshida continued. "Yeah, Bitch-sensei fits her way better than Irina-sensei." The class continued to chuckle. "Well, there you have it. Welcome, Bitch-sensei!" "Let's get started, Bitch-sensei!"

  "I hate you all so much!"

  "She's fitting right in." Koro-sensei commented outside as the class laughed and Irina releasing her anger. "More or less." Karasuma next to him said.

  "Don't screw with me! Bunch of rotten brats!" Her yell echoed through the classroom building.

  "Thank you, Karasuma-san." The yellow teacher continued as the latter pulled out a gun as an attempt to assassinate him. "I want my students to be able to converse with an actual foreigner, and really, who better than a globetrotting assassin?"

  He saw all this coming? The black-haired man asked himself as he glared.

  "Time to top off my sugar reserves after all that hard mental work!" If Koro-sensei had seen the half-pulled out gun, he ignored it.
