September 9th 

On the 9th September at the old Campus building, the students were gathered.

"What brings us together here today on a school break, no less?" Kayano announced as drums began to play. "Is the nation's current egg glut," a newspaper clipping showed lots of unsold eggs being stacked up.

 "in which the excess eggs, rather than being sent to market, are being discarded in bulk."Kayano was at Koro-sensei's desk addressing the rest of the class.

"Oh, yeah!" Isogai spoke up. "I heard about that on the news. What a waste!"

"Right?!" Kayano agreed, nodding. 

"So I came up with a plan." She grinned, holding up a file titled 'My Plan'. "To salvage those discarded eggs and assassinate Koro-sensei!"

 "Whoa!" The class gasped, looking at her in surprise. 

 "What, kill him with eggs?" Nakamura asked.

"Bah!" Terasaka scoffed, tossing some pellets up and down in his hand. "So you cook up a dish, toss in some of these babies?" The pellets were shown up close. "Like he won't see right through that?"

Kayano smiled slyly. "I gave it a little more thought than that." 

She looked to the side. "The first steps are already in place, thanks to Mr Karasuma." 

Karasuma and Bitch-sensei turned to her from the side. He nodded. "Yes, everything's already set up in the yard—" 

"To the yard, everyone!" Kayano rallied. 

The students gasped when they saw the giant dome-shaped mould in the middle of the yard. 

"Whoa!" In front of the students stood a giant class cylinder shaped like a pudding.

"This mould...and those eggs...don't tell me..." Kanzaki exclaim in shock. Kayano turned around brightly. 

"Yep! We're going to make one enormous pudding!!" She smiled sheepishly. "I call it...Operation plan name the : Pudding Popper ! "

"Operation Pudding Popper?" Nagisa repeated while they all were still marvelling at the massive machine. "Koro-sensei does have a sweet tooth..."

Kayano grinned triumphantly, swerving around.

"Let's make his impossible dream come true!" Kayano yelled, her eyes sparkling. "Frankly, I'd like to eat some too!!"

"Uh..." Nagisa smiled warily. 

 *A pixel illustration showed Koro-sensei devouring the giant pudding-like Pac man.*

"We'll embed bombs and Anti-sensei BB's in the base of the giant pudding," she explained.

"Chomp, chomp, chomp," went the pixel Koro-sensei as he ate his way down to the base. 

 "When he gets to the bottom of the thing..." Kayano narrated.

"AHH!" The whole cake and Koro-sensei exploded once he broke the base. 

 Isogai smiled with interest. "It might be worth a try..." 

 "He does tend to go crazy over sweets and sexy stuff," Okajima said, grinning. Kayano looked determined while the others stared at her in surprise. 

"Okay, let's use this time when Koro-sensei's not around and go for broke!" Isogai encouraged them.

The scene shifted back to the mould.

Later on it was getting late in the afternoon near evening and the sun was starting to set.

"Nice work, Kayano." Rio walked over to her. "You really thought all this up after reading an article on the country's egg surplus?"

 "Sorta." She was sitting down on the ground watching the machine. "I actually have wanted to try and do this for a while now. Since the Ministry of Defense was willing to shell out the money this time I figured why not go for it?" 

Karasuma was shown slightly stressed as he looked over the bill.

"When my mind fixed on something I just keep rolling." Her smile tightened. "I guess..."

"Most of the time of the time Kayano is more in the background than centre stage." Nagisa thought as he watched them both. "That's probably why I've always pegged her as a supporting role type. But look at her now. I never imagined she could get so fired up, prove anyone can shine and what they're into you becomes real." The class gathered as the bolts were loosened. "Once we've let it chill overnight we check to see if it's firmed up enough. If it is then we remove the pipes, then after that we loosen the bolts holding the lid in place."

The class gathered as the botls were loosened."That's right!" 

Isogai helped manage it. "Then we blow air between the walls of the mould and the pudding itself."

"Release internal lock!" she ordered.

The lock was released. "Once releasing the mould, we carefully shore up the sides with softened gelatine and agar to add just that bit more firmness." Okuda and Sugino were coating the side."Then we top it off with caramel source and lightly toast the top." The caramel was poured on top and then a flamethrower was used to crispen it.

"We did it !!" Everyone cheered as the pudding jiggled.

"Well wow, that sure looks delicious!" Sugino yelled.

"You completely forget there's a bomb planted in there," Nakamura aid as she took a selfie with the pudding.

Korosensei was starring with his mouth watering at the pudding."A-and I'm allowed to eat this entire thing?!!"

"Oh sure." Kayano chuckled. "I just didn't want those eggs going to some landfill."

Koro-sensei gripped Kayano's hands while he cried tears of joy. "You've made me so happy!"

"Well, see you, Koro-sensei," Nakamura said, waving as she left. Isogai smiled.

Koro-sensei was drooling and crying as he took out two spades. "At last my dreams come true!!" He dived into the pudding at once as the others watched. "THANK YOU!!"

Karma's eyes followed hers as he watched Kayano turned away and followed the others. Koro-sensei was devouring the pudding at Mach 20. 

"Oh he's really going after it," Sugino said as he and the others watched from the classroom window.

"I have a feeling you won't be very long until he reaches the bottom," Sugaya commented.

"Don't worry I've installed a security camera into the base. I'm keeping my eye on it," Takebayashi told them from behind his laptop. "The second he reaches the bomb will be detonated by remote control. We'll know he's eating his way to it. Once the light starts pouring in."

Kayano lifted her gaze back up to the pudding. "By pudding. It'll be..." Then there were more flashbacks of her working out the design. "That sense. I'll use the scale model to test its strength first." Later the small pudding failed. "Ah! Not another collapse!" 

Then there were scenes of her muttering about pudding in her sleep.

"MY PUDDING!!" She yelled when they flashed back to the present with her bashing her head against the window. "I can't let something I put my heart and soul into be blown to smithereens!!"

"Kayano, take it easy!"

Terasaka grabbed her , yanking her back from the window. "Don't get emotionally attached to a damn pudding !" He yelled over her screaming. "It was made to be blown to bits !"

"No , we can't ! We need to keep it in the backyard forever as a monument !!" Kayano screamed as everyone sweat dropped."IT'LL ROT!!"

The pudding was imagined as a monument for all to look at.

"This is insane , Kayano , it's just a pudding." Meahara snapped , Karma who stood beside him shook his head slightly in exasperation.

Korosensei was infront if them in an instant. "Phew."

"My jaws need a break." The students froze. "Oh by the way amid all the deliciousness." He held up a bomb. "I caught a feat wiff of this."

"The bomb." Nagisa looked surprised. "And the detonators been detached."

"I ate a path from caramel to pudding to dirt and proceeded to tunnel from underneath to remove it." He looked smug as he held the bomb in his mouth, annoying Takebayashi. "I assume the bomb was your handiwork, Takebayashi?" he swallowed the bomb. "Well, your calculations were spot on and if I had not picked up on the distinct scent of plastic explosives your scheme might have very well worked."  He patted him on the shoulder. "Next time you will account for strange odours. Right?"

 "Right..." Takebayashi sighed.

Koro-sensei chuckled. "C'est la vie but since you all work together to create this wonderful concoction you should enjoy it together." There was a portion of pudding shown for each person in individual glasses. "I set aside a nice clean portion for each of you."

Meahara smiled in amusement as he and the others took a portion of pudding. "So he gets the jump on us yet again."

Korosensei held up a book on the issue. "So we'll be exploring the complex role of a perishable goods surplus in our next civics lesson."

"Yes, sir..." The class groaned. Kayano sighed as she looked at her pudding. "Too bad Kayano. Or do you feel better now ?" Nagisa asked as he and Karma stood next to the greenette. Kayano laughed.

"Honestly no offense, but I didn't think you had it in you to be so hardcore," Nagisa told her. "It was cool to watch, a nice change of pace."

"Not even your closest friends get to see your true blade." Kayano said as Korosensei's face turned scarlet with a bright red circle.

"I'll do it again. This is where a pudding fan can be top notch assassin." The smile on her face dropped and Kayano face darkened , glaring at his teacher from behind. "I've got any number of jiggly blades at my disposal."

At the distance , Karma's eyes spark that no one could understand. "Yeah. But how long do you think you can control those blades ?"

The scene changed to students back at school. "Once the break was over Mr Karasuma got down to business and really ramped up our training. " The students were racing through the woods climbing up the mountain rocks. "Today's PE class was a first."  The students were jumping over rocks and through woods. "Parkour crossed with Cops and robbers. The cops are our toughest teachers."

Koro-sensei was dressed in a police uniform with a Barreto while Mr Karasuma was just in regular camouflage gear. 

Koro-sensei was using the Texas accent again. "Hey, now, there ain't no reason it can't be fun. You're just trying to haul all the good times where yourself." He talked in a weird Texas accent and blew some gum. "Putting me in charge or hold down the fort."

Karasuma looked annoyed. "What did you expect? You can't be the chaser. This is training." He slipped on some gloves and went to chase them.

" Mr. Karasuma will catch up to us eventually, but's a big mountain." Okajima jumped over a large rock while Fuwa and Rinka followed behind.

"And there's a time limit so at best he'll tag maybe two or three or two of us tops," Fuwa said and she jumped over the rocks. 

 "Yes, even if that many." 

 "No kidding."

Karasuma's eyes narrowed like a predator. "I heard that," he said lowly, bending down. "Reach 80 metres. Boom."

"You're under arrest," Karasuma said smugly, holding up his hand which was covered in red paint. "Caught you red-handed."

"Hayamo, Chiba." Ritsu grinned, dressed in a cop's uniform as she listed off the tagged targets. "Fuwa, Okajima. You're out!!"

As they were in "jail" which was in a circle that Karasuma draw. 

Koro-sensei laughed as he provided over the captured. "Yeah. I'm telling you don't get caught," Okajima said while on the phone. "He's making us do worksheets! It sucks!"

"Oh, come on." Sugaya snorted, leaning against a tree while he was on the phone. "This isn't some battle manga. Seriously how do you not know he was on your tail till after he tagged you?" 

"Look, just be careful," Okajima replied in annoyance. "He's like a ninja for all you know he's right there." Karasuma appeared behind Sugaya.

There was a blood-curdling scream, causing Okajima to cringe ad hold his phone away. Then the line when dead.

"Sugaya, Sugaya!!!" Okajima yelled at the phone desperately.

Bitch-sensei chuckled. "Big man's on the hunt all by his lonesome." 

She lounging by the river. "Well that works for me. I'll just pull him down by his tagging hand and we'll go at it right here in the wilderness."

"Bad cop good cop will take on a whole new meaning. Bring it on you son of a—"Bitch-sensei was tagged so hard her face was dunked underwater by Karasuma.

"Professor Bitch. You're out." Ritsu winked, showing the updated list.

"Wait a second." Okuda's eyes widened. "This is cops and robbers technically..."

"We can tag them back in!" Sugino yelled from on top of the large rock. "Okuda! You're a genius."

He jumped off the rock and headed to the bushes.

Karma had managed to sneak off in nowhere to be seen.

"Sugino?" Okajima looked up when he saw Sugino waving his arms from a distance.

"You come to bust us out?" He quickly realised what Sugino was trying to tell him. "Uh, huh!"

He tapped on Koro-sensei's shoulder. 

"Yeah?" The teacher turned around and saw Okajima not very subtly flashing a bikini photo of a young woman. "Oh! Heh..."

Sugino had tried to free them so he signaled Okajima (pervert) to do sorting.

Koro-sensei slid the photo into his pocket and turned his back to them. "Just this one time."

"Sugino, Now!!" Okajima yelled, waving his arms.

Koro-sensei tensed when he realised he'd been had and Sugino had tagged all of the prisoners back in.

"Five prisoners freed!" Ritsu said, disappointed.

Karasuma groaned. "Dammit!" 

He called Koro-sensei. "Mind explaining how prisoners are escaping on your watch?"

 Koro-sensei adjusted his sunglasses. "They're shrewder than we give them credit for." His face when bright pink when he looked at the photo. "But good heavens, those things are really enormous!!!" 

 "Are you taking bribes?!!" Karasuma yelled, having already detained Takebayashi, Toka, and Hara.

"Look whatever. If you let the next group escape so help me..."

The scene shifted to a few minutes later.

"Actually Koro-sensei," Toka said, having been handed over to Koro-sensei with the other prisoners. "You know my little brothers come down with a rare illness. Poor guy's been bedridden for weeks!"

A silhouette of her brother in the hospital was shown. "When I told him what we're playing. He texted back. Win one for me." She gave a broken sob. "If he finds out I was captured the shock might be too much!"

 "Go." Koro-sensei turned away, crying silent tears. "This cop never saw anything so go."

Toka jumped to her feet without hesitation. "Thank you, sir! You're the best" The rest of the prisoners ran away as well.

"Four more prisoners free," Ritsu said, sighing as she appeared to be sweating.

Karasuma rose an eyebrow. "Umm Ritsu-San....what are stripping ?"

"I-I-IT'S PART OF THE DRAMATIC AFFECT !!" Ritsu blushed.

"Come in, Karasuma!" Koro-sensei called, dressed in a dirty cop's cosplay. 

"Do you copy?" he yelled. "How in the world are these inmates breaking out of. Prison?"

"That's my line!" Karasuma hissed into the phone , probably pissed.

*Offcial Korosensei scandal Bribery*

Sugino had tagged everyone but Bitch sensei. As Karasuma was angry at the dumb octopus for falling into the student trap. Karasuma told Korosensei not to fall in to the student trap again as Korosensei nodded his head in understood........but it didn't take long.

*Official Korosensei Scandal : Covering for prisoners*

Karasuma was getting angry. He managed to find everyone except  for Karma. He was chasing Nagisa's group when they ran out of time.

All of the sudden Karma jump down from a tree.

Nagisa looked like he was about to passed out."W-where...were.." he breath heavily and bend his back , his arm on his knees for support.  "...you K-karma-kun ?"

"I was just jumping from tress to tress to get further away from Karasuma sensei." Karma pause with his arm cross , looking at Karasuma who continue to lecture Korosensei. "But I guess I over did it cuz I realized I was already at the top of the mountain after 5 minutes." He brush the leaf off his shoulders and stretch his arm. "So I just waited for the game to end." 

Major students blinked blankly at him. "Is he even a human ?! "

In the end Karasuma looked annoyed as he walked over to Koro-sensei. "When it was over our game of cops and robbers / parkour ended with us getting away."

Koro-sensei looked sheepish as Karasuma yelled at him for taking bribes. Later on he and Sugino parted ways when they walked home.

"See you tomorrow," Sugino said. 

 Nagisa nodded. "Yep, goodnight." 

He walked down the opposite street. 

"Things were going fairly well. Second term was off to a promising start."

He paused when he passed a convenience store where a magazine headline read. 'A yellow menace targets F-Cups and above!'

Nagisa's eyes widened and then narrowed. "No way. "

The next day, Koro-sensei adjusted his roll book. "An excellent beginning to second term, it must be said. The mutual respect and trust the students and I share grows stronger by the day!" He walked down the hallway to the main classroom. "How wonderful it is to see their shining faces look up at me with such—UNBRIDLED DISGUST!!"

The students all looked at him angrily, having gathered loads of magazines detailing a yellow menace who was stealing women's underwear.

"They're totally talking about you aren't they?" Okano said. 

"How could you do that stuff?" Mimura questioned 

 "We're very disappointed in you, sir," Kataoka said coldly

They had revealed a magazine stating an underwear thief.  Everyone was furious at the teacher and disappointed.

"Oh, no, wait I'm innocent!" Koro-sensei pleaded, looking at the magazines in horror. "I don't even know anything about this!"

"So do you have an alibi?" Rinka asked. 

Koro-sensei looked confused.  "A what now?"

" Where were you on the evenings of the incidents in question?" she replied curtly. "And can anybody back you up?" Koro-sensei quickly racked his brains.

"Let me see...." "I was vigorously shaking a bag of season fries." He was shown jumping back and forth at a great hight. "Alternating between an altitude of 10000 meters and 3000 meters respectively."

"No one could back that up!"

"That's enough, guys," Isogai interjected firmly. "Come on now, he's not a perv. He's done some creepy things sure. But even if you add them all together what have you really got?"

"He's read some adult magazines." The flashback was shown of him on the pile of porn magazines. "And been bribed with dirty pictures. He stared intently at pinups during recess. Spammed Lingerie companies with requests to let him give their models of tentacle raw..."

Isogai trailed off, turning away. "Ugh, just turn yourself in..."

"YOU TOO ?! ISOGAI-KUN ?!" Korosensei shook his tentacles widely.

"This is an outrage. I stand wrongfully accused! Don't you believe me? Very well to the teachers lounge!! I'll show you what kind of upright citizen I can be." He rushed to the teacher's lounge and opened a drawer of dirty magazines.

"Behold my pinup stash!!" He stoped and started throwing it away.

"I'll toss every last one of them without so much as a twinge of reservation!!" he froze when he came across a bra, shocking the others.

"You're kidding right," Terasaka commented, looking unimpressed.

Then Okano came rushing in with the roll book. "Oh my gosh, guys! Check out the roll book!" 

The roll book showed comments on the girls bra sizes. "He put letters next to all the girls names..." 

"Koro-sensei knows our cup sizes?!"

"Huh!?" Kayano looked appalled when she saw 'Forever flat' written down. "AND WHAT IS FOREVER FLAT SUPPOSED TO MEAN YOU EIGHT ARM-TWO-BIT—" Okuda had to hold her back.

"And what about this?" Hiroto held up another list. "It's a breakdown of all the girls in Kunugigaoka with an F copper above weight right.

"Wait!!" Koro-sensei looked desperate. "That can't possibly..."

His students didn't look like they wanted to hear any more of his pleads of innocence.+ Koro-sensei placed a cooler on the desk. 

"You know what we need? A good old fashioned after school barbecue. Doesn't that sound like fun? Here. Get a load of these succulent skewers I threw together!" 

He held up skewers which had bra's attached. "Uh?!" 

There was complete silence as Koro-sensei froze in horror of what was happening....which end up holding bras everywhere as all the students kept finding bras everywhere around the campus.

Wow..." Sugino looked disturbed.

Kanzaki grimaced and looked away.

"This is nauseating," Kataoka said. 

 Okano scowled, looking away. "Gross." 

 Koro-sensei was speechless. The scene shifted to the end of the day as the uncomfortable atmosphere remained. 

"That's...that's all for today..." Koro-sensei said weakly. "Boys and girls." His head was low and he turned away and walked out. " ....I'll see you tomorrow." 

The students all remained where they were sat in silence. Nagisa stood up warily. "Is he stealing underwear? That'd be pretty serious. I mean we're talking an actual crime."

"Compared to blowing up the earth," Karma commented , stretching. "it's down right adorable." 

"What do you think Karma-kun?" Nagisa asked , receiving everyone's intensity of attention.

He was the smartest one in class and they learned that all too well , after all the Takaoka incident. Not only that both other incidents so he must've saw something they missed again.

"Well , if I were a Mach 20 underwear thief." Karma tossed a basketball which had a bra clipped on. "I wouldn't leave behind such shoddy evidence."

Nagisa grimaced as he held it up. "A ball from the equipment shed." Karma glanced up. "He'd have to know if he did this , he'd be dead to us as a teacher." A flash back showed Korosensei bonding with his students."For that teaching-mad monster , I'd think loosing our trust with this nonsense is right up there with getting assassinated in terms of things he wants to avoid." 

Karma explained as everyone seem to saw his point.

Nagisa smiled fondly. "Yeah. Have to agree with you."

"Then who's doing all this stuff?" Kayano stood up. 

"What do you guys think , it's it obvious ? " Karma spoke up as everyone stare at him.

There was only one conclusion left...there must be a fake Korosensei.

Later on in the evening the students were hiding behind a van. 

Fuwa smirked. "Justice will prevail now the great, and very mature, detective is on the case."

"You say on the case I say exploiting our parkour skills to trespass," Nagisa said dryly.

 "Hey remind me again, of all the places in town. What makes us so sure the creepers going to strike you next?" Terasaka asked. 

Fuwa grinned, looking over her shoulder. "First off, this place is a camp for pro entertainers. The centre though I've been known only popular and songilicious girl group has been staying here for the past couple of weeks." 

 She held up her phone which had Ritsu on it. "Right." 

Ritsu smoked her pipe. "Based on the suspect's profile. The probability that he'll show is 99.7%."

The students had decided to go to a gym that had a big busted dance group. 

The group that went to spy consisted of Nagisa , Kayano , Karma , Terasaka , Fuwa and of course Ritsu in their phone.

"Indeed." There were over a dozen bras shown hanging outside on the clothesline. "Because camp's over after tomorrow. In no way is our man going to let these top tier trophy slip through his fingers!"

"Uh, huh..." Terasaka sounded concerned.

Nagisa and Kayano watched over the car. 

"Koro-sensei?" Nagisa whispered when he saw Koro-sensei in the bushes dressed in his ninja outfit. "Okay, please see that he's here to nab the bad guy too."

"That get-up ain't exactly helping me presume his innocence," Terasaka commented warily.

"Look he's so pissed off at the real criminal just looking at all that underwear gets him steamed," Fuwa said. Koro-sensei was flushed.

"Right, wrongfully accused my ass," he remarked.

Karma warn. "Heads up."

Everyone immediately duck but turn to look at him , confuse but he didn't look back at any one of them. He just continued to stare straight , as everyone turn to the direction he was staring.

" Someone's here," Kayano whispered as a yellow painted motorbike helmet popped out from the bushes.

"A big guy with a yellow head," Nagisa said. 

 Karma didn't look slightly surprised. 

The man in the helmet swiped the underwear from the lien with well-practised ease. Koro-sensei burst out of nowhere and tackled the man to the ground. 

"GOTCHA!!" The struggled. "How dare you impersonate me and act on my lurid fantasies."

"I'll strip you naked and take care of you from stem to stern!" Koro-sensei threatened.

His students were disturbed.

Meahara dumbfounded. "Excuse you , what the fuck ?"

"Uh, I think this might make him worse than an underwear thief..." Nagisa commented as he watched.

Korosensei had jumped after the man as well as the students , taking of the helmet to reveal....

"Karmasuma sensei's subordinate ?!"

"You?" Koro-sensei sounded unimpressed. "What earthly reason could you have for—"

He never got to finish that sentence as a cage of sheets that had been hidden, rose up and trapped him.Shocked Korosensei froze when four white sheets appeared trapping Korosensei as the underling escaped.

" I negotiated with the government to borrow one of Mr.Karasuma's men. He lured you right into this pen of anti-sensei sheets."

 An all too familiar voice stated as the students all glared at the man clad in white.

"It's what your students did on the sounthern island. Youngsters have such limber minds. First confine then strike." The familiar voice continued as the students got closer.

"Now , then. Korosensei...."

Karma looked over , looking unsurprised.

" Let your final death match begin." The man in white said snapping his fingers as a shadow loomed over Korosensei. "Korosensei...." The teacher looked up as he saw a pair of familiar yellow with a little blue eyes.

"Compare to me .. you are....weak."

The screen went black
