After the Squid Vs. octopus Splatfest results came in, that being that Squids had won over Octopuses, the octolings started to think about how they had been unfairly pushed into this Splatfest. This had been the second Splatfest that they had ever been able to participate in, but the Inklings had plenty of Splatfests to know what was going on. They also knew, according to article 3, section 2 of Splatfest law, that whatever option of a Splatfest won, was legally better than the option that lost. This meant that Inklings were legally better than Octolings. This fact made the Octolings incredibly jealous, and they became eager to change things. They began to think that they were being unfairly treated by the Inklings, and the results of the Splatfests were rigged.
This, however, was definitely not the case. Inklings wanted to coexist with Octolings and had won out of determination, and hard work. They had been kind to the Octolings after they lost, saying that it was a good fight and that everyone should feel proud. But the Octolings, being prideful creatures, thought the Inklings were mocking them. Most Octolings got it into their heads that Inklings were trying to push them back underground where they had come from. In their aggression, they began to be more hostile towards the Inklings, targeting them during Turf Wars, being aggressive to them in Inkopolis Square, pushing them around, and making them feel inferior .
Agent 4 and Agent 8, having both been integrated into regular society, noticed these things, and began discussing them with other members of the New Squidbeak Splatoon, including Callie, Marie, Agent 3, and the newly recruited Pearl and Marina. All of them were worried about the aggressive behavior of the Octolings, and how this may contribute to the takeover by the octarians. Callie and Marie were especially worried, seeing as they had been a contribution to starting the integration of Octolings into Inkling society, since they had been the ones to write and perform the Calamari inkantation, and that is what had made octolings able to turn from the Octarians. They discussed this many a time in Octo Canyon, especially with Agent 4, who in turn, told Agent 8 and Agent 3, spreading the news to every member, but, unbeknownst to them, DJ Octavio had heard through their conversations, and was hatching a plot of his own.
About a month after the Squid's victory, the time of the next splatfest, Octolings took to the streets of Inkopolis and started to demand to Pearl and Marina that the Splatfest results should be recounted, and no Splatfest should be held until the results of the last Splatfest were recounted. They also demanded that a group of three Octolings should supervise Lil' Judd as he counted the points. As they approached, Marina quickly sent a message to any member of the Splatoon who would read and told them to come help in any way possible. Agent 8 came and hid amongst the crowd, while Agents 3 and 4 took to the rooftops. The Octolings had started to demand that Marina should take their side since she was an octoling like them. Marina felt incredibly offended that just because they were more genetically similar, she should take their side, and ended up telling the Octolings that the next Splatfest would still be on, the results of the previous Splatfests and if the mob didn't leave, no one there would be able to participate in it.
Well, the mob didn't like that. They started to riot more violently, and all agents, including Callie and Marie, were forced to come in and settle the mob. Before the mob had dispersed through, they had managed to tip Crusty Sean's food truck, knock Judd and Lil' Judd from their napping spot, and break a few windows of shops, including Ammo Knights, an active provider of the Squidbeak Splatoon.
Once the damage was cleaned up, Pearl and Marina made a broadcast that all Octolings involved in the attack on Inkopolis Square would be permanently banned from Splatfests, due to their unruly behaviors. After setting up an emergency broadcast button for the Off the Hook recording studio in case of another riot, the Splatoon dispersed, only to be called together again an hour later for a shocking discovery. When they had been dealing with the riot, the main meeting place in Octo Canyon had been destroyed, every Octarian, and piece of Octarian machinery had disappeared, and DJ Octavio had once again escaped from his snowglobe prison
More riots occurred, and they got more and more violent. So violent, and aggressive towards Off the Hook, the two members had to go into hiding in Octo Canyon, where Callie and Marie had been desperately trying to figure out what had happened. After they left, the Octolings made their own show and greatly diminished the rights of Inklings, including banning their participation in Ranked Battles, Splatfests, and being on teams with Octolings. Judd and Agent 8 had stayed there, Agent 8 being an undercover spy on the Octolings, and Judd, just so people wouldn't be suspicious of him.
All these decisions were made by Cap'n Cuttlefish, who had not been participating in any events that would require much work, as he was getting much older. He had been staying in the Deepsea Metro, communicating by Group chats, and voice calls. He was getting more worried about the escape of DJ Octavio each day with no information and ended up giving the agents more and more training exercises to do, so they would be ready.
Some weeks later, all the Agents were doing training exercises, working with different types of weapons that they weren't used to. Agent 3 was working with dualies, as they were a fairly recent invention, Pearl and Marina were, reluctantly using Rollers, and Callie and Marie were using brushes. They had only been training for half an hour, and had just started to get the hang of their new weapons, when disaster struck. DJ Octavio had carefully plotted for his time to attack the Splatoon, and he had decided that this exercise would be the greatest way to overpower them, and take them by complete fought as well as they could but ended up retreating, and after notifying Judd and Sheldon, went to the one place that they knew that they knew the Octarians didn't know about.
DJ Octavio raged into Inkopolis Square looking for the Splatoon but was met instead with angry Octolings. DJ Octavio saw an opportunity and promised to the Octolings that he would give them everything that they needed, as opposed to the members of the Squid sisters and Off the hook. The Octolings, though recognizing their old leader, still thought that he could be the one to help them, now that the Splatoon was gone. DJ Octavio had achieved everything he wanted, except for crushing the New Squidbeak Splatoon, which was the next thing on his list. He just needed a way to find them...
