Before the game had started the students were practicing their free running in their respective groups planning different routes and clearing their doubts, as they were practicing their technique from the lessons they had and from what they were taught some of the students reminisced the familiar times of when they had played cops and robbers when they were kids and that using a large space such as this really makes their heart pound.

Karasuma who devotes himself to devising training programs that students wouldn't get sick of and using the pirates to help in doing so in the process and Korosensei would then utilize what had been taught and have them play games that they would be able to get into, it truly is a good combination. If it weren't for the assassination and the world ending, Nagisa bet that the two teachers could have been good friends.

"…But hey, there are only two cops right? And it's just Karasuma sensei for most of the time. Even for Karasuma-sensei, this back mountain is huge. Even if he can tag us, it'll probably be two or three at most." Okajima told the group that he was in confident that it would be a piece of cake they rest agreed stating that the one they had to worry about the most was Korosensei and that once he was on the move it would be advisable for all of them to stay well hidden. Unbeknown to that group, Marco had flown past them and heard what they had said, sighing, he knew that it would not be that easy from the get-go from the abilities of what they had seen from Karasuma

Once the game was started, the pirates were at different locations watching over the different groups of students that had separated themselves into, not making a sound nor letting known of their presence watching the game ready to help at any given moment

As Karasuma ran through the forest he had been constantly finding and pointing out mistakes that the students had made as they ran, broken branches that indicated they had just passed through, footprints that had indicate who they belonged to and sounds that let him pinpoint how far they were. Judging the distance Karasuma leaped off the edge he was on and used the hills around him to push himself off and go faster, with the students in sight he tapped out all four students in Okajima's group at once.

The four students looked at their teacher in shock not expecting to be out as quickly as their teacher simply told them with an evil looking grin that they were under arrest sending chills down their spine. As the group that was just caught walked to the prison trying to warn the others, Marco who was overlooking the scene landed by Karasuma and changed back, leaving only his arms and legs covered in his flames retaining his wings and claws "did you really have to scare them with that grin of yours?" he asked questioning the teacher, "what do you mean I scared them? I didn't do anything to them." Karasuma replied oblivious as to what Marco meant as he, instead of carrying on the conversation spotted his next targets and leaped down the hill, hooking his legs onto the tree branch hanging upside down behind Sugaya looking like the grim reaper and caught him. Marco watching from his spot still in his semi-phoenix form sighed at Karasuma's antics thinking that he was more suited for assassination instead of being a government agent before he changed into a phoenix and flew up giving a shrill notifying the others that another student had been caught

While the students were being caught in a narrow cave, Irina was hiding inside exited that Karasuma was coming after them, planning to make him indecent by her own means only to nearly be drowned by the very person she was planning to make a move on.

As Ritsu notified everyone of Bitch-sensei being arrested as well along with the shrill from Marco, kayano who saw the notification "oh no." she said "we keep getting done in, it's a back mountain massacre." She stated scared while Nagisa who listened sweated at her exaggeration saying that there were only getting arrested. Okuda then reminded them that it was a game of cops and robbers to which Sugino realized that they could tag the robber in the jail cell and release their teammates, jumping up the hill that led to the classroom telling the rest to follow. Nagisa and Karma who were following behind okuda and Sugaya, "he sure is an idiot, that Sugino, did he forget, even though Korosensei said that until the last minute he would not move from the front of the jail cell." Karma informed trailing off as they reached the class before stating that if we would be able to tag the students without the octopus noticing, then they could have killed him a long time ago.

Finally realizing the 3 man combo of the teachers that was created, they realized that the combo of the strongest creature and the strongest him were coming to attack them and curse them with more homework. As the four of them were in the bushes they questioned and tried to think of plans of how to get their teammates out

An impossible game of assassination cops and robbers with the students running from the two monster teacher cops wanting to survive for cake, from the beginning of the game with Karasuma on pursuit and with Korosensei or 'Korocop' being the warden of the jail cell until the last minute which meant, that in other words the cops are completely and perfectly covered in terms of offence and defense. Korosensei who was able to see the badly hidden Nagisa and Sugino he chuckled "the robbers seem quite vexed don't they? Because any attempt is impossible while I'm here."

"You sure about that Korosensei?" Korosensei turned around sharply to see half the group gone. "Nua?! Where did everyone go?!" he looked around to see Karma standing far away from the circle with the group that had escaped behind him possibly being given advice by the smartest of the three brothers. "Korosensei~ have you forgotten? I'm a pirate now and with Nami-san the cat burglar I learn much more korosensei~" Karma said as he sneered at Korosensei who became infuriated, as they went back into hiding once more despite already being seen "really those robbers taunting a cop that is unable to move…"

"Damn… he turned all oppressive as soon as e put on that cop outfit." One of the students grumbled

"Shut your mouth prisoners! Be quiet and submit yourselves to the penal code!" Korosensei shouted at them going back into his cop mode as the students who were doing the math drills given to them questioned the penal code given to them and questioning that he was just trying to make them study drills. As they heard the shrill from the overall overseer, Marco, who was flying about and the notifications from Ritsu telling them of who was telling them of those that were being caught. The students knew from their experience and instincts that all the robbers would be eliminated before the 30 minute mark. Karasuma-sensei was indeed serious about catching them all.

Karasuma did not hold back, every possible footing he would push himself off and tap as many students as he could continuing without stopping "Even if it's a game of tag I won't hold back, the students, according to how seriously I pursue them… they should be able to grasp the possible movement of free running and the psychology of being a target." He thought to himself as he took out Terasaka's gang. Once they were out he checked his smart phone counting how many students were left.

Meanwhile, back at the classroom in the prison Okajima seemed to come up with an idea, tapping korosensei on the shoulder Korosensei looked behind to see Okajima holding out to him a stack of photos of gravure models with huge chest. Looking through the photos, he put them in his shirt pocket and turned a blind eye to the letting the robbers run. Given the signal, Okajima told the group in the bushed to com and save come and save them, Nagisa and Sugino coming out of the bushes this time tapping out the captured students and escaping.

Karasuma who was looking at his phone received the notification that the students he had captured had escaped, seeing this, he immediately called the Korocop, "hey… how did the captured robbers escape?" he asked trying to control his anger but veins were popping appearing on his head as he tried to control his strength in order to not break his phone as he held the conversation. Korocop nonchalantly said that the students were extremely skilled before ogling the photos that were given to him making Karasuma lose it and shout at korosensei, he then calmed down and informed korosensei of the number of students he would be sending over and that if the same thing happened again he would not be let off.

At the jail, Yada made up a story that would convince the naïve Korosensei which worked as she was cut off by Korosensei telling them to go acting as if he did not see any students. Soon after, every robber that was captured managed to escape either through bribery or by Korosensei's slacking which gave rise to an escape boon throughout the mountain. Karasuma having enough stormed to the prison where Zoro was there sitting by the tree with his three swords watching in amusement as Karasuma shouted for the octopus while the students who had just escaped informed that Korocop said that he was free and that he went to Nagano to eat some Shinshu soba. When Korosensei had come back, with soba in hand he stood there slurping up his noodles as Karasuma was lecturing and scolding him.

"Well, let the octopus be." The two teachers turned to the Zoro who was sitting by the tree the whole time "Karasuma, I doubt the octopus would let another student escape, although, I have to say with each escape from now on it would be more difficult for you to arrest them." Zoro stated smirking at Karasuma as the teacher took off back into the forest thinking light of what Zoro had said until he realized that it had became more difficult for him to sense the presence of the students. That was when he realized what the green swordsman had meant, the octopus were giving tips to the students that were captured, while the pirates gave advice on how they could sneak around without being caught and without using Haki. Seeing a 4 man cell dispersing upon seeing him, he smirked praising their quick observation which would make it nearly impossible for him to catch all the students by himself. With the two teachers simultaneously teaching the same field from different points of view, which would lead as to how the students would be able to grow drastically. As Karasuma took out Muramatsu, he made his conviction that he had no attention to cooperating with Korosensei since, if it was him alone within a minute everyone would all end up being captured in the end.

Emerging from the bushes, he saw a four man team which consisted of the students which specializes in mobility suspecting that they were there to challenge him, taking on their challenge, he told them to not head to the cliff area on the left ahead of them, which other than that he would take them on. After being told of where they were not to go to, they shouted a roger before splitting up and heading into four different areas, seeing their movement, Karasuma praised them for being able to do well in running away proud that they were able to master the basics that were taught to them in the 1st semester but, they were still lacking in their swiftness. Karasuma was able to catch up to them quickly and take out each of them before they travelled far the group of students not being able to escape from their human teacher while he's serious

After Karasuma had caught all of them, as the student group regrouped with their teacher "you ran pretty far, impressive." He said praising the students before saying "but it'll soon be the last minute, if he moves this cops and robbers game will end with your loss." He told them but Maehara who was catching his breath chuckled, "it's our win, Karasuma-sensei." he stated with bated breaths while their teacher looked at him in confusion questioning what they meant. Yada then asked Karasuma "because, Karasuma-sensei, you don't fly through the sky together with Korosensei, do you?" which ended with a response saying that Karasuma would have stabbed the annoying octopus if he had that sort of leisure. The other students then smirked and said "then, Karasuma-sensei, you can't go back to the pool from here within a minute can you?" they emphasized making Karasuma realize his mistake

At the pool, Sugino, Karma and Nagisa were in their homemade pool holding their breath underwater with a real and anti-sensei knife in each hand in any case that either teacher came, smirking at Korosensei who was in a state of shock unable to move since as long as Karasuma can't come back, with Korosensei alone he would not be able to touh them while they stayed underwater for a the whole minute. The pirated had then come out of their hiding laughing at the plan that the students had come up with which made both teachers unable to catch and take out their students Ace then shot a ball of fire into the air signaling the robbers win as the time ran out.

After everyone regrouped, the students all cheered at their win and reward of cake sponsored by Karasuma who huffed as he watched their celebration "so they lured me out as decoys, I'm surprised. That they could outwit two instructors." He praised while Korosensei was sobbing in the corner biting on a handkerchief at the loss "It's kind of odd~" Kurahashi said "even though you two don't work well together, only when you guys are teaching, you guys are super in sync." She said pointing at both teachers. Korosensei then regained his composure, changing his hat back to his teaching hat stating that they would surely be in sync because they were both instructors and if there were student before them they would feel the need to nurture those students because that is the instinct of every instructor.

"Look at the dirty cop saying something respectable. Aren't you better suited to be a robber?" Terasaka asked walking past Korosensei who became shocked by the distrust his student had for him defending himself asking what Terasaka meant because he was a holy man about to question how he would be a robber, cutting himself off when a newspaper landed by them talking of a underwear thief with characteristics which would fit their octopus teacher.

.

The next day, korosensei was walking to the classroom expectant to be greeted by his student's gaze of affection to him from the trust that was strengthened between them and himself, opening the door to the classroom to receive a flying kick to the face where he dodged successfully an saw the eyes of disgust that his students were giving him.

"An underwear thief specializing in targeting large-breasted women, the culprit is a large man with a yellow head. 'Nurufufufu…' he laughs and leaves behind mysterious goo at the scene of the crime." Korosensei reading the article was shaking in his boots, the E students accusing their teacher at the obvious and accurate description as they said of their disappointment questioning his morals. Korosensei desperate to save his image and respect from his students said that he did not know of this. Then came the question of the person who delivered the kick to Korosensei courtesy of Sanji asked for Korosensei's alibi, his whereabouts when the incident happened where and what korosensei was doing. Korosensei replied clearly that he was shaking around some French fries jumping between the heights 10,000m~30,000m. The students all shouted at their teacher questioning how anyone would be able to confirm the alibi of their monster teacher. The students as they continued trying to prove to themselves the innocence of their teacher slowly lost the will to continue doing so with what their octopus teacher were able to do.

Korosensei was in utter shock at the trust that was being broken by the accusation when Isogai had came to his rescue telling the class that they could not accuse him that way bringing Korosensei's attention and hope to Isogai

"It's true that korosensei has a lot of little worldly desires." Isogai started addressing the class as he tried to defend his teacher but as Isogai remembered what his teacher had done how at times his lust got the better of him. Isogai himself stopped himself and shakily with his back turned demanded the truth from their supposed misunderstood teacher.

Korosensei fed up with his student's accusation, opened the sliding door while telling his students that he would remove all the gravure models that he had in his desk. As the students followed their teacher to the faculty room "I will remove all the contents of my desk… and…" just as korosensei was removing the contents of his desk to pull out a pair of bras. The students stood there in shock at the revelation as their trust to the octopus teacher had started to waver greatly, Okano's voice then rang out from the classroom asking them to all take a look at the roll book. As they did so, beside the names of the girls were their cup sizes. To the despair of Kayano when she had seen her name to have been written with a 'Forever O'

Maehara was flipping through the whole roll book when he came across the last page which contained the names of women in the city with F cups or higher. That seemed to be the last blow to the students glaring at the Yellow creature when he, while sweating profusely took out a cooler container trying to put up a cheerful front saying that they should all have a barbeque "Now, take a look at these skewers! I thought we'd have one after school and prepared these!" he said taking the skewers out proclaiming them before he trailed off as what was skewered were not food but instead bras.

At that point, the student regarded him as the monster he was, as they backed away from him, regarding as trash, some not even able to look at him while others had pure fear in their eyes. Hearing the words that came out of his students mouth about him, Korosensei could not believe what was happening and turned to the last source of hope that could possibly help him, Luffy, to see that Luffy was slumped against his table unaware of what was happening with the obvious snot bubble while his sworn brothers, family and crew members had their hands on their weapons or were in a position where they would use their devil fruit powers feeling disgusted and betrayed by someone that they trusted, the only exception to the students and pirates behaviors were Karma who was smirking as though he was enjoying what was going on and Robin who seemed to be thinking of what was happening.

All of a sudden, Korosensei, super freak accusation, after the morning incident, no one said a word to korosensei, no one even made an effort to eliminate him and no one listened to his lessons. When the last bell rang, Korosensei, by the end of the day, walked out of the class with a half hearted shivering voice as he greeted his students as he went out of the class, shameful and not able to face his students as his eyes were glued to the floor as he walked out.

Once Korosensei was gone and everyone were keeping their bags, Luffy stared at where Korosensei had left before he turned to Karma who started laughing "He was on pins and needles all day~ don't you think he's running away because he can't handle being here?" he said as he leaned back in his seat when Nagisa approached them asking whether or not their octopus teacher had really done it despite the countless evidences that were presented. Thatch who came into the classroom by the window then leaned onto Luffy's table laughing as he said "Even though it was disgusting, compared to a world explosion, isn't it cute?" Nagisa could say nothing in return as he in a way agreed with what Thatch had said but, he questioned why his attitude towards Korosensei now was completely different from earlier when Korosensei was trying to explain and defend himself. Thatch then laughed and looked at Nagisa straight in the eye "oh yea, we're still pretty cautious bout that since we don't know what is actually going on here." He said seriously before he put a hand on Luffy's head ruffling it as the angel hummed lying on the table as Thatch continued "But, since Luffy here has not said anything yet." A pause "that means that what was said was not entirely the truth so for the time being we're just cautious of that octopus."

"Although, if I were a mach 20 underwear thief, I wouldn't leave around these pieces of evidence." Karma had stated bringing his best friends attention to him again as he reached down bringing up a basket ball, presenting it to Nagisa saying that it was found in the PE storage. The basket ball however had a frilly bra strapped onto it making Nagisa sweat at the sight of it "If he did something like this… he knows that he would be dead to us as a teacher." Karma had said and was cut off when Luffy finally got up "I think for Koro, if the people who seen he had seen as his family were to have lost his trust in him, he would want to die before that happened." Luffy said as his head was still on his hand as he looked at Karma and Nagisa.

Nagisa slowly agreed with Luffy knowing what the young pirate had said was true, Kayano on the other hand were still unsure about to ask who they thought was the actual culprit-

"…a fake."

Fuwa's voice suddenly interrupted Kayano and the conversation that was being held with everyone turning to her as her eyes lit up with fire shouting in passion as she narrated "A FAKE KORO-SENSEI! THE CONVECTION OF A HERO'S TALE! IT'S THE WORK OF AN IMPOSTER, THE EVIL VILLIAN!" as the group present sweat dropped or in the pirate's case, laugh at how exited she was with her fictional idea

"The fact that he imitates his body colour means that… the culprit is someone who's acquired information on Korosensei!" she stated as she informed them that Ritsu would help them look for clues as Karma stood up from his seat exited "sounds like a plan" he said "although, I have no idea why they'd do something like this." he pulled Terasaka who was walking towards the door exiting the classroom and Luffy had by then sat straight as he grinned at the small group seeing an adventure while Karma continued saying that "at any rate, if these rumors spread out and our bounty couldn't stay in town anymore, we'd have nothing to gain. Why don't we beat the hell out of the real culprit on our own and have that octopus owe us one?" he said as Terasaka was confused as to why he was involved and stared at Karma as he use his shoulder as his arm rest while Luffy on the other hand cheered in an adventure going off to find and drag Zoro along with them while some of the other pirates decided to follow along like the brothers along with Robin who found it interesting while those that didn't decide to join didn't think much of the incident.

Once night came, the whole group had met up outside a fenced up property the students in full black while the pirates were as per normal although, they had spend an hour before that trying to find Zoro who had finally gotten himself lost but thankfully, with Robin's powers they were able to find him and retrieve him before he would have gotten himself arrested for possessing swords or going to the next city. They had waited for Zoro to come back before jumping over the wall into the private property concealing their presence as they landed in the property. Fuwa was in a pose as she was filled with excitement chuckling to herself as she did a self introduction narrating "Nearly adult in mind and body, the great detective is here!" in a pose while the others waited for everyone to make it over. "so, Fuwa. What makes you think the real culprits gonna hit this building next." Terasaka who was forced to come asked as the whole group stood around Fuwa then said "this is a training facility for certain performance pros. During these two weeks, I heard an idol group full of huge breast is practicing their dance for a new song. That training camp will be over tomorrow. There's no way the real culprit would let the ultimate laundry slip." She had said relaying the information that Ritsu had come up with. Although, their attention was brought away from Fuwa when Robin had beckoned them over signaling them to hide behind the bush and look to the other side, and as they did so what they saw… was a Korosensei who looked like old man trying to be a burglar having cold feet from the evident sweat dripping down his round face.

Ace who had seen the sight was trying his best not to burst out laughing and ruin their cover, Sabo was better at hiding it but Luffy was outright laughing but his laughter was muffled by Zoro who had resulted to covering his captain's mouth so that his boisterous laughter would not alert everyone of what was going on and Karma snickering at the back while using his Smartphone trying to steady his hand taking pictures of the ridiculous get up his teacher was in planning to use it against him when he gets the chance. Once they had calmed down from their laughing fits, Nagisa and the others pulled their hoods over their head letting them hide in the darkness behind the bush as they whispered. "What the… was Korosensei thinking the same thing?" Fuwa asked as she ducked as Terasaka replied saying "no… no matter how you look at it, it looks like he's gonna steal something." They whispered as they observed their teacher "look! He's more exited looking at the underwear than being mad at the real culprit!" Fuwa said as Korosensei was breathing heavily at the sight of the underwear as Nagisa said that he could not help but see Korosensei as the real culprit with the way he was acting.

Just then, Karma sensed a presence the pirates seemed to do so as they stiffened. Karma turned to the area where he felt the new presence and told everyone to look to the wall at the other side, as the group did so, Karma told them that someone was coming, when they turned they saw a man jumping down the wall, landing and pressing his back against the tree before he started running towards the laundry. While the man got closer to the students and the group, they noticed that it was a big man with a yellow helmet, at the revelation, the students knew that their teacher was innocent and the real culprit was the clearly human in front of them currently. But, with their observations, they also could tell that the culprit's body movement proved that he was not any random pervert or civilian though, they were cut off when the man had reached out to grab the lingerie but, was stopped when Korosensei had grabbed the man with his tentacles restricting him as an obvious tick mark appeared on his bright yellow head tackling the man to the ground. Although while pinning the man on the graph Korosensei ended up saying suspicious things that made the sight look like Korosensei was doing something more dangerous than the underwear thief with a laugh that would match the reports as well. Korosensei then pulled the helmet off shouting for the imposter to show its true face. But at the sight of the imposter everyone was shocked because as they recalled who the man was they realized that it was Karasuma's subordinate recalling the name Tsuruta. Tsuruta baked away as Korosensei asked why he was doing such an act to sabotage the teacher when there was a beep sound

"Koro! Get out of there!"

Luffy shouted as he became aware of what was happening but it was too late the students getting tense and the other more experienced pirates got ready to fight. Korosensei could not react fast enough as the cloths stretched and encased the teacher making him unable to get out from all sides but the top. As Hiruta got out of the cloth cage as Korosensei was distracted, a familiar yet detestable voice was heard as a new figure appeared

"He had a debt to his country, so I borrowed Karasuma-sensei's subordinate" the man had explained as he had walked into the clearing "I had him lure you into this cage of anti-sensei sheets." The man who was Shiro said as he seemed to have noticed the students, but they knew that Shiro would not be alone. Luffy looking out for the silver haired boy as Shiro ignored them and continued "It's the method your students used on the southern isle. Before hitting you, we surround you." He said as Korosensei who was inside the cloth cage managed to piece the puzzle together that Shiro was there and was looking out for Itona while worrying for the safety of his students but, he had no time for worrying about other people now, with the last warning from Shiro and his students calling out to him, Itona appeared from his only possible escape and started attacking without mercy.
