Nagisa still couldn't get his mind off the memories where Karma had almost lost his life. But the evident way that Karma was building a wall around him made Nagisa want to climb it to see what's in the other side. 

He sighed underneath his breathed and turn to glance at the center train Red hair who's staring at the board , dully.

The episode opened up with Bitch-sensei writing on the blackboard.

" Oh, sexy guy," She said coyly in English. "It's a miracle."  The class watched silently."What , Really ?" She recited in English.

" Everyday chitchat is actually quite simple." She switched back to Japanese. "I'm sure you all know someone who says nothing but phrases such as  "maji" great and "maji" bad. "Maji" here. One way to speak like this in English is with the word "really"

She turn to Kimura "Kimura you try" 

Kimura tensed "L-Leally "

" Nope : awful. You're L's and R's are a mess , The pronunciations of L and R doesn't jib well with Japanese people. I understand what's mean but it feel so wrong." She made an X symbol.

"Oh....okay," Kimura replied uncertainty..

"Karma Akabane show him." Bitch Sensei commanded.

The screen flashed to the black of the classroom , Karma peek through the book that he was reading and look to the front with a blank look. He proceed to let out a sighed before do what he was told." Really "

The Class stare in awe when he spoke fluent English with no trace of any accent.

"Correct !" Bitch Sensei exclaimed as she turn back to continued her lesson.

She turned back to the class. "Don't run from your weakness. Overcome them !" She lectured. "To that end , i'll be checking your pronunciation regularly from now on , and if you screw up your also and Rs....." Her eyes narrowed"......I'll punish you with a French kiss in public."

The Intro was skipped

Bitch-sensei collapsed in her chair in the staff room and groaned."Man teaching is such a pain !"

Karasuma looked up from his work. "But the student seem to enjoy your lesson , though."

She shrugged. "Am I suppose to be proud of that ?! I am an assassin !! I'm stuck here while I try to kill that octopus !!" Her cleavage was focussed on. "And speaking of octopus... " A pink-faced Korosensei was standing above her wearing a green traditional Japanese tea while his face turn red and a creepy grin appear from his face.

"He's gazing at my boobs while elegantly SIPPING TEA !! "

Korosensei chuckled."I do admire your real life lesson drawn from experience. Oh How marvellous !! "

Bitch sensei withdrew her knife. "Oh shut up ! And die !!" 

She tried to slash him but missed.

Karasuma stood up."Calm down. He's just that kind of target." 

"Shit." She curse in English. 

"I won't stand for this !"Bitch-sensei huffed and walked away. Karasuma and Korosensei watched her curiously as she left. 

Bitch-sensei was out in the hall, looking subdued. " I  can't afford to stay cooped up in here like this. " She stared at the floor intently. "But how on Earth can I kill that monster ? "

A rope suddenly descending from the ceiling and coiled around her throat and yanked her up.

 "A wire trap ?! " Bitch-sensei was struggling to keep the rope from strangling her. "Why ?! "

"какой сюрприз, ирина ( What surprise , Irina ) " a voice that speak Russian from behind , a man with heavy boots stepped into view.

"Seeing you play teacher with those children," he had a heavy Eastern European accent in his Japanese. "It was like the set up for a comedy sketch "

Bitch sensei struggled a little to stay conscious. " м-мастер ?! ( S-sir ?! )" 

"What are you doing ?" Karasuma interrupted them. "This is your only warning, pal. Let her go."He pointed to the ground sternly.

"Не волнуйся, (don't worry )" he cut of the rope. "она знает, как ...(she knows how to free herself.) "

When suddenly the rope was snap. Bitch-sensei was gasping as she hit the floor with a hard tud. She groaned in pain before glaring at the person who cut the rope but her expression turned surprised  by the one who stood in front of her.

She gasped. "K-Karma ?"

"Lovro ?" There stood Karma who titled his head aside , questionably. With a knife in his right hand and a rope in his left hand , which he was use to cut of the rope. "Я не ожидал, что ты здесь.(I didn't expect you to be here.) " Karma said in fluent Russian , shocking both Karasuma and Bitch-sensei.

"Shi-sonomono ?! " Lovro hesitated , Bitch-sensei noticed his weird action. She took a moment to finally realize something between both of them."ж-ожидание" (w-wait)

Bitch sensei eyes winded. " Ты его знаешь ?!" (You know him ?!) "Какие ? Ребята, вы давно встречались, а я не знал о чем ?! Какие ? Ты встречаешься с ним на миссии Ассасина ?"(Have you guys go on mission before that I didn't know ?! You guys met before ?!?!) her eyes bulged in confusion."Shi-sonomo— what ?!"

"You're half right. But also half wrong !" Korosensei appearing with half his face with purple X and the other half a red O. He pushed Bitch-sensei and Lovro's faces apart , Karma looked warily.

"Why are you doing here , Ultra Quiz ? " Karasuma asked.

"I don't like that nickname! just call me  "Korosensei" already" Korosensei replied irritably, letting go of the two assassin's head.

"It's you...." Lovro said.

"Indeed ,  as an assassin , she isn't much to be feared." Korosensei commented." she's crap."

Bitch-sensei gritted her teeth. "WHO'S CRAP ?!"

"However , she's just happens to be the kind of assassin my class needs. Shall we hold a kill-off to find out who's the better assassin ?" Korosensei announced."This contestants : you and her." He straightened up. "The rules is simple : Whoever kill Karma first wins !"

" Wait. Hold up..." Karma deadpanned. "Why am i the target here ? "

"Because if it were me , the contest would never end !" Korosensei replied smugly as he handed over the two green knives, using two napkins to protect his skin."You have all of tomorrow. "

"I see." Lovro accepted the knife. "A mock assassination , eh ?" He poked the rubber knife and smirked. "Alright...then." He walked away.

Later on , Karasuma was addressing the students on the field."...And there you'll have it. There may be some slight disruptions today , though your classes should remain unaffected. Carry on as you usually do."

Nagisa sighed , growing pity from his certain classmate. "Will Karma ever catch a break ? "

"Karma- kun ~" Bitch-sensei called brightly. They all looked over warily. "Great Job today !" She cane bouncing over to them smiling a little too sweet, while she carried a drink canister. "You must be thirsty ! Here have a nice cold drink!"

Karma look at her with a blank face.

"Come on , knock it right back ! It's good !" Bitch-sensei chimed.

"She obviously put something in it..." The students watched from a far , not surprised. "She definitely did. "

"You Probably put a muscle relaxant and immobilized me , and stab me at your leisure." Karma looked unimpressed. Bitch-sensei blanched, looking away. 

Bitch-sensei scowled but then tried to force a smile. "Oh, hang on!" She bent down and placed the drink on the ground. "I'll put it here." She then forced herself to fall over. 

"Owie!" she yelled and then quickly sat up. "Carry me piggyback, Karma-kun ! Piggyback!" 

The class watched in disappointment. Toka covered her face, embarrassed for her. "...Bitch-sensei, please just stop."

"This is just sad..." Hiroto commented.

Karma just stood up and walk away without another glance.

Lovro hummed, watching from behind the tress "Have you got no shame , my idiot apprentice?"

"Professor Bitch..?" Isogai said easing her feet.

"you wouldn't even fool us with that routine , either." Meahara pointed out.

"What do you expect ?! There's no natural way to fake-seduce someone you already know !!" Bitch-sensei Fire Back.

A scene suddenly showed a middle-aged man sitting next to an attractive young woman.

"It's like a paid escort trying to put the moves on her old man!" Bitch-sensei narrated.

 "What?" Meahara rubbed his eyes in disbelief. "I'm sorry, what?" 

 "Do you smoke?... Of course, you do, Da—I mean, sir!" the woman would say.  

 "Even a club hostess would find it awkward as hell if the dust happed to be her father !! This is the same thing !!"

"LIKE HELL WE KNOW THAT !"

"What kind of daddy issue does she have ?" Meahara whisper into Isogai's ear.

Isogai scratch his head and sighed deeply. "I don't think I want to know.."

"Uh oh. " Bitch-sensei looked worried. "I'd better finish the job quick. With Karma skill , he could take down his target in a split second."

During a short break , Karma was leaning against a tree relaxing while his classmate was having fun. All of the sudden Lovro appear out of nowhere , lunging towards Karma at a frightening speed and freaking out all of the student. 

"Head-on?!" Bitch-sensei exclaimed when Lovro attacked. In a flash, Karma dodge it and in a flash he grabbed and pinned Lovro's arm down on the ground. Lovro was shocked at his reaction. Karma swung his foot out and stopped just short of Lovro's skull , Karma pinned Lovro arm in a strong grip and crushed his wrist making him yelp in pain while he release the knife from his hand. 

"WAOH !" Yoshido and the others gasped.

Bitch-sensei on the other hand who just spill out her drink after watching their fight.

"Holy crap!" Bitch-sensei's eyes bulged. 

"That was awesome!" Hinano smiled brightly. 

 "Man, Karma have to teach us that move!" Okano said excitedly. 

 "Yeah, totally badass." Hiroto fist pumped the air.

Karasuma blinked in amazement.

"You may be skilled , but you seem to overestimate your ability as a retired assassin to kill a soldier fresh from a special forces." Karma remark coldly, picking up the dropped knife. 

Lovro eye's bulged. "He's tough ! "

Bitch-sensei reeled back in shock. "Even Master can't kill him ! Do I have any hope at all ?!"

Karma narrowed his eyes at her, pointing the knife in her direction. "I'm sure you understand that if you fail to kill me today...."

Bitchsensei and Korosensei were terrified.

Korosensei hid behind her making her pissed. "Wait, Why the hell are you scared ?!"

Koro-sensei shivered, "You can't lose, Professor Bitch ! Do your best!"

Karma started to walk away." My knife can stab 5 times in one second." He then proceed to gave them a last glance that pierce through their soul. "Looking forward to seeing you." 

Korosensei was sweating nervously. Bitch-sensei looked over Lovro who share a concerned face.

Later on the students were chatting among themselves while they ate lunch.

"Hey , check that out , guys !" Yoshida said , looking out of the window.

Nagisa looked over and saw Karma eating lunch outside.

"Yeah. Karma-kun eats lunch over there all the time." Kayano replied staring up alongside Nagisa.

Meahara smirked."And now one woman draws near. Bitch-sensei is going for it !"

Bitch-sensei hair was slightly unkempt as she looked down at the boy."Do you have a moment , Karma-kun ?" 

Korosensei and Lovro were watching from afar."She has a knife under her sleeve , I see."

"She surely knows that won't work on him. What a fool." Lovro scoffed.

"Aw, come on, Karma-kun," she said slyly, making him look away. "I really want to stay here." She took off her jacket, leaving her in her tank top and skirt. "You know that." His eyes narrowed at her. 

"One little poke and it'll be over." She smiled coyly. "I'll give you something in return. The best of the best, like you've never had it before."

"Wait, is she trying to bribe him with sex or something?!" The class behind them look disturbed at Bitch-sensei actions.

"Okay , here I go ~"

Karma stare at her blankly as she began ran around the tree.

"A wire trap huh ? " Karma realized , the second she move to use it , shocking her and everyone who was watching from a far when he caught the thin visible wire with his bare hand. Using his distraction as an opportunity she jump towards him , not knowing that the red head was directly looking at her the whole time.

Bitch-sensei raised the knife. "Got cha !" 

Karma blocked it just in time,  holding her hands in a bone crushing grip.

Bitch-sensei gritted her teeth. "Damn it ! If this turns into a contest of strength, there'll be nothing I can do !What should I do ?! " The class was still watching from the window. She grimaced.

"Karma-kun , please....." Bitch-sensei made the most "adorable? convincing demure look she could muster."let me stab you." 

Karma continue to stare at her blankly . "Do you seriously think that will work ? "

Bitch-sensei know that plan obviously didn't work as she keep trying to push the knife down. The wind hollow over them and lifting up the edge of Karma's shirt , Bitch-sensei looked over with eye's winded in horror , a heavy painted breathed escape the boy. 

Heavy breathing could be heard , the screen flashed to the boy tied , brutally to a chair. The camera flashed down to reveal the flesh of his skin had torn apart. A big figure with masks laughed , holding a blood stained wrench tool in hand. A pure agony scream shot through the room to feed the laughter from the cruel man. The boy was hyperventilating unknown to him , the world around him blossom with white flowers that covered with blood.

The word form shakily on the black screen  "To live is to devour others."

"So....." The camera flashed up to a woman with beautiful purple dress , the wind taut her purple hair. She turned around and smiled glory at him.  "....do you accept me ?"

The screen cut off where Karma pulled the green knife towards his neck shocking everyone more further , he cut it. Meaning Irina won and she get to stay at the E-class. But no one dare to speak , not even Irina who sitting on top of Karma. 

"H-he got him..." Okajima state , unbelievable as the class share the same expression.

The boy blink as he regained consciousness of the world around him while looking at his surroundings. Karma got up as he notice a bruise of her hand as he grabbed them surprising the teacher as he stared to inspect her hands.

"There's a little bruised but not broken nor sprained. " Karma turn her hand over to the back and gently careless it. " You should be fine but don't forget to put some ice so the bruised will fade more quickly " Karma promise and carefully check her hand.

"Hold up !" Bitch sensei eyes sense suspicious around the boy , his breathing , the pulse in his hand. All of them were wrong. The boy infornt of him looked exhausted , she press his head against hers when she felt a steaming heat against her own forehead. "Are you burning up ?!"  She looked over , worriedly. "His skin were freezing ! "

The boy stay didn't said anything and before Bitch-sensei convict any further , the silence was broke by a crowd of students went over to celebrate.

"You did it Ms. Bitch-neesan !"  Muramatsu put a arm around her neck. 

She paused and looked absolutely back fired , glaring at him. She looked like she had forgot the little incident between the red head. "Stop with the stupid nickname !" She stood up trying to strangle him , Hara and Hinano laughed trying to calm her down.

Muramatsu hid behind between Kayano and Nagisa who watched in amusement with Bitch-sensei braking and breathing fire in her mouth like a dragon. The class continue laughed , at the distance Karma watched from the window peacefully.

In the End , Bitch sensei get to stay with them. Nagisa smiled. "Indecent and arrogant, yet straightforward: Bitch-sensei is our E Class English teacher. " They were in class as Bitch sensei was teaching then English but something has been bothering her. She couldn't help but to keep thinking about what happen back then.

"That's boy sure is mystery." Bitch Sensei thought as she wrote down some English things on the board. "What was he hiding ?"

She turn make a quick glance to the red head as they make eye contact without others notice.She hurry up and turn back to the board ,  continue writing. Unknown to her that the pair of eyes pierce through her.

"Too bad..." His eyes shifted to the window , the pain on his back began spreading. His breathing soon become shallow , the noises in the classroom began to tuned out followed by an intense music from the background.The screen faded to black and the music abruptly stopped. "...time is slipping fast..."
