Then Yada suggested "why don't we use code names like the assassins on the island?" when Koro agreed he said "even those 3 hardheads should be used to calling people by nicknames" mocking them then suddenly Sanji came in using Mutton Shot on Koro making him scream as he missed on purpose making a hole on the floor without saying anything he walked to wards the one piece table giving the food on his left hand to the one piece characters serving the ladies first while giving everyone desert that looked too good to eat. As Koro reached out for the last one, the desert was taken away by Zoro.

As Zoro confirmed that the desert was his, Koro asked where his share was apologetically, "there's none for the octopus that has been making fun of us here. Instead should I make that octopus into Luffy's snack?" Sanji said coldly as Koro was in the corner punching the wall as it made a lot of squish noise his hand was cut off by Zoro who was irritated by Koro. Koro dejected just sobbed in a corner. After they ate and started thinking of the names to use they were notified by Karasuma that the one piece characters was not allowed to participate since it wouldn't be an exercise anymore and that the names they chose was a bit too… unacceptable.

After the competition, everyone was in a way… dead tired. Though, in the end Koro was chased down by everyone in the class field for the name he chose though, Nagisa and Karma wondered what the name the one piece characters chose was.

Time skip to the athletics festival. As usual the one piece characters were not allowed to participate as the school had no idea of their existence. Although, the one piece characters were hiding one side so that they wouldn't be spotted. When they saw the foreigners they felt that it was unfair but, they knew from watching the student's practice that they were stronger and had the power to defeat their enemies. After a bit of advice from Koro and the rest they started the game against Class A. when Class E was in their 'ultimate defence' formation. Class A's foreigner Kevin then went on the offensive and knocked down both Yoshida and Muramatsu.

With the power Kevin had the 2 boys were flung off to the audience area. Luffy was about to get out and stop class A. But he was stopped by Ace and Sabo who were just having a serious look towards the students. Then when Kevin went on the offence again, Isogai told the class to use 'tentacles' as nearly all the students jumped they landed on Kevin and the Class A students pining them down.

The remaining Class E pushed down the pole on Kevin and the Class A students. While Kevin was pissed at the A students dialect, Asano was thinking of a plan and commanded the attack squad to the K formation. As the A students were getting closer, Isogai and attack team used 'mucus' and went through the middle of the two Class A attack teams. When Isogai and the team went through the middle, the attack teams turned back and ran towards Class E.

Then, Isogai and the team led the A students to the audience. As the audience escaped Karma provoked the two foreigners the battle between Class A and Class E began. The other students were watching thinking of how Class E would win and that they were looking at something interesting. Asano then started giving order to his classmates and was assessing the 6 class E students who were dodging all the offence. Asano was scheming in his head when Karma asked Isogai "isn't it time?" Isogai agreed. Then as the class E ran, suddenly, Muramatsu and Yoshida suddenly went out and jumped onto the A class pole. Asano questioned and found out how they were able to get on the pole without being found. Though at the side lines, Luffy and the rest were laughing while Sanji left to go back to the class to make refreshments for the students. The one piece characters just found it amusing the way class E fought as in a way, class A was playing into class E's hands. Soon, the 6 man group broke free of the A student's hold on them using the 'speed of sound' tactic. When they had jumped on the pole, Sugino was pulled by one of the foreigners which made the pole move that had Asano clinging to it so that he wouldn't fall off. Asano then told the big guy to stop as the pole may drop and as Yoshida grabbed onto Asano. He took off his head band and said "I'll take care of them myself."

As Asano took off his head guard, he flung Yoshida away kicked Okajima away. Karasuma and the one piece characters were shocked at what Asano did. Nagisa who was back at his class pole thought of Asano as the last boss and that it was expected since he was the chairman's son. Asano on the other hand was using his feet to kick away the class E students even though they still clung on. But, they had a problem. The A students were coming back to their pole. As Asano kicked Isogai away he thought of it as his win, but, when Isogai fell he immediately regained his balance and let the rest of the class E use him to get to the standing of where Asano was and bring him down.

When the rest of the students looked back to where class E's pole was they only saw Terasaka and Takebayashi holding up the pole. At the hiding place Brook was doing his usual 45 degrees while laughing. Takebayashi on the other hand was talking about Leverage and the about the orders for the A students below them were waiting for orders. While on the other hand Asano was in a way being bullied by the E students who were on his level. Even though class A was going on defence was giving Itona a push up to down the pole. When Itona was on the A class pole it was game over. Since, the moment he got on the pole he pushed the pole to their floor making it the defeat of class A.

After the game, while they were cleaning up. Robin went towards them and told them to clean up as soon as possible since Sanji made food for them. While Luffy and the rest had already gone back up. When the students went back to the class they saw the field was filled with tables of food and that there were seats for them. While everyone was happily eating little did they know of the gruesome event that was happening in the chairman's office.

After the kindergarden incident. Everyone got their sad results and they felt it was expected since they didn't study at all except for karma who regained back his top spot. When they went back to the class they received a present form the ministry of defence which was a new physic ed uniform. While Koro got a shock for the whole day. Soon after they were trying out the uniforms with the one piece characters. Though with Law's powers they were reminded that what they have couldn't be compared to what they have.

When the students went to rescue the bitch sensei who got 'captured'. The moment they went in they got captured. The god of death was talking about his plans when there was suddenly fire around him. "Oi. Isn't it a bit too much? Seeing that you are taking us as a hostage for your plans." Ace said looking at the god of death when Luffy walked up to the bar and said "why are you putting on a fake face? That isn't your real face right?" they got a shock, they didn't realise what Luffy was talking about. Then the god of death started laughing as he said, "You're right! This isn't my real face I got a real shock when I heard you!" the GOD said as he was pulling of the mask. Then Robin asked "if we try to escape from here you won't kill us right?" the GOD agreed saying that it would actually be more interesting if they did, they realised that he must've known that Takebayashi had a bomb. "And Bitch-sensei I can tell you're faking get up already." As Luffy said that. Irina got up and said "I never knew that my cover would be blown this quickly, even though you're not an assassin."

The students were shocked by Irina's change. Then the GOD suggested "how about u fight me? If you win I'll let you guys go but if you don't win all of you are going to put these bombs on your neck is that alright with you?" he said while holding the collar. Luffy agreed when GOD said that he would open the cage so that the students would watch as well. He just saw the cage being sliced up. He looked at where it could have come from and he saw only holding one of his swords instead of using 3. They decided to use the space where the cage once stood. And the students were moved out of the way with the one piece characters guarding them. Before they started, GOD made one more condition which caught the one piece characters off guard. He said "also if I win, I'll tell them of you and your crew's origins okay?" they were stunned but Luffy was determined to save the friends he had, either way the truth about their origins would come to light soon enough anyway.

As soon as he agreed, GOD received a punch to the face and was flung towards the wall. GOD walked out as though nothing happened, brushing the dust off his clothes. They were soon exchanging blows with each other then, Luffy used busoshoku haki to harden his hand. When Luffy's hand changed colour. Nagisa recalled the time when Luffy first came in and thought 'his hand really did change colour!' while the rest of the class was just shocked at what they saw. When Luffy's hand hardened he brought it down on GOD and knocked him out.

When he was knocked out. Luffy looked at Irina and said "don't run away, the class likes you already so take good care of them." Irina then knew her true feelings. That she loved being with the class, though, to spoil the touching scene Koro and Karasuma barged in when they saw what had happened, they knew everything was solved. When Karasuma was calling the ministry of defence, GOD suddenly got up and had a knife by Luffy's neck. "Just what I would expect from someone who came from a different world. Anyway what are you and your friends who are pirates doing protecting and playing games with students training to be assassins?" Karasuma just clicked his tongue while the rest were shocked by what they had heard. Then when GOD tried to behead Luffy, he himself was thrown towards the wall. Ace and Sabo then made a ring of fire around GOD making him trapped inside.

"I really can't stand guys who break promises." Said Zoro who was pointing his 3 swords at the GOD behind the flames as it disappeared. GOD then laughed and said "I know more than your origins!" he then threw papers at the students which the students picked up and read. When they saw the papers they got a shock, since the papers they had were wanted papers of the one piece characters! "Also for Fire-Fist Ace! I'm not sure if you know but after you died, Whitebeard died and his power was taken by Blackbeard! Ahh~ your 'father' sure died a pitiful death without his powers with him!"

That was the last straw. Ace lashed out at GOD and started using his powers on him. Ace was then stopped by Sabo, all of them were shocked while the straw hat crew were just trying their best to contain it since that battle at marineford also dealt a heavy blow on Luffy. All of a sudden GOD was screaming non-stop. They turned to see Law holding his heart squeezing it. "You know that your life is in my hands right now, I can let Ace-ya burn it or even let swordsman-ya slice it in two. I don't know how you heard about it but what I've been hearing was just plain disgusting you are treating us pirates like trash! Bad mouthing the great whitebeard whom all pirates respected!" when Law finished, Ace broke down and was crying. As Ace was crying, Luffy also started crying silently since it brought bad memories, Sabo was barely holding it in. the brothers pulled their hat to cover their face so that no one would see. Law was also just thinking of what he could do with GOD's heart. The assassination classroom characters felt that it wasn't right if they said anything now.

What caught their attention after was Robin walking towards Law, she took the heart and borrowed Zoro's sword. As she walked towards GOD he thought Robin would return his heart to him but instead. She used her power made GOD look at his heart without blinking. "Karasuma-san, you won't need to take him into custody." As she said that she cut GOD's heart into pieces. "The marineford war was a time where many of Ace-san's friends died someone who doesn't understand our pain has no right to say anything." As the remains of the heart fell from her hand GOD also fell… dead. When the Karasuma's colleagues came to collect the remains of GOD. Sabo was carrying Ace while Zoro was carrying Luffy. As they were about to leave Nagisa called out to them asking "will you guys come to school tomorrow?" Sabo answered saying "I'm not sure, I don't think that Ace and Luffy would recover too quickly." As Nagisa felt a bit dejected he felt a hand on his head, when he looked up he saw Sanji. "Don't worry we will come back eventually, when that happens we will have a party again alright?" Sanji smiled at Nagisa as he said that.

The next day none of them came and the air in the class was heavy even Koro couldn't feel cheerful. Although lessons were still being thought what hung on everyone's mind was the straw hat crew. After school, they were talking about what happened with GOD. They were still shocked at what happened when Koro appeared behind the students. "Why don't we go and visit them? I asked Karasuma-sensei for their address." Koro said cheerfully, then the students decided that they would go since they would be able to find out the answers they need.

On one of the days they didn't have school they gathered and went to the apartment where the straw hats lived in. when they knocked the door, they were greeted by a sleepy Sabo who opened the door for them Sabo had extremely messy hair and his clothes were half buttoned though he was already wearing his glove. As Sabo opened the door for them he turned to the back and was trying to wake Luffy and Ace who were on his back up. As they saw what was happening, they started to laugh (I forgot to mention that they had a bigger house now since they had a lot of people from the one piece in the Assassin class) as the students came in they saw Sanji in the kitchen cooking lunch, Law sleeping on the couch and Robin reading a book. The rest were in their rooms.

As the students came in Sanji said hi, Sabo gave up on getting the brothers off and was just dragging them around to show the students where they could sit. Robin, got up closed her book and walked towards the kids and started talking to them. "I suppose that you came here to talk about where we came from." As the students slowly nod, Robin asked Sanji if it would be alright if they talked about it, then he said, "Yeah, the grim reaper said it out loud as well. Karasuma gave me the ok when we said that we would tell you guys everything." Sanji finished as he stopped cooking

Then the rest of the straw hats came out surprised to see the students. Though they just kept quiet as they came down. "I'm sorry you guys had to see that." Said Nami as he reached the end of the stairs. When they started explaining about new world and their past, Class E was shocked by the past they all had. Though, when they finished they saw Ace and Luffy waking up. When they saw the students they thought that the students would treat them differently. (They didn't know that the Class E knew about their past) But instead they heard Koro say "hello Luffy-kun. You know that you can't skip school u know?" in a way they were surprised at how they were treated but then Dr yaba suddenly burst into the mansion. "Luffy-kun! Someone came through right after it was repaired!" whenever news of people coming through the 'gate' they were always on their feet as they never knew whether or not they were friends or enemies.

When the figure came in Luffy got a shock and said "Shanks?! Why are you here?!" Shanks just looked at Luffy and smiled saying "your grandfather told me where you were and told me to go into the gate when it appeared." Then as shanks looked over Luffy, he saw Ace making him say "Ace?! How are you alive!? I thought you died!" as Ace looked at shanks he said laughing "ahh… I don't know when I opened my eyes I was already here" as Shanks looked at Sabo he said "what's the revolutionary's second in command doing here!?" as Luffy and Ace started Laughing, Sabo said "thank you for taking care of my younger brother and stopping the war back at marine ford so that my brother Ace could have rest in peace then." When Sabo said that he was bowing down, holding his hat at his chest. "Brother… wait. Luffy had a second brother?!" Shanks said shocked. As Shanks was shocked Class E saw that Shanks had a missing arm. Curious Nagisa asked "Shanks-san, why do you have a missing arm?" Shanks looked at Nagisa for a while and said touching the area where his arm once stood saying "I lost this arm because I saved Luffy which is then we made a promise giving him my hat." As Nagisa recalled what Robin said when koro tried to take Luffy's hat.

"Ah, then I'm going back now I need to make improvements so that I can send all of u home in one shot." Dr Yaba said as he left. Then Usopp nervously asked "umm… how's my father?" Shanks looked at Usopp and said "Yassop right? He's always talking about you when he gets drunk!" he said laughing and then turned to Luffy saying, "Though to think that you learned your haki from Rayleigh-san I was shocked!" as they chatted for a while more when Shanks looked at Nagisa he stared for a while and asked "are you a girl or a boy?" Nagisa screamed saying "I'm a boy!" though the real thing on Shanks mind was the potential that Nagisa had inside him.

After talking for a while more and Shanks getting information of what had been happening while they were in the assassination classroom universe. Once Shanks got a hang of what was going on he turned and asked Koro "do you want to try to fight me?" Koro's face then had green stripes as he said "sure! But please don't kill me I still have to teach these kids." Koro said as he laughed.
