    Note: This story was made a month or so before the Octo Expansion was released so you may notice some changes that differ from the final game-wait what am I talking about? This is a fanfic,not The Cutting Room Floor. Anyway,this is non-canon(obviously) so yeah. This is the story of an Inkling named Four and an Octoling named Eight(kinda generic,I know but I couldn't think of any other names). Despite Agents 3,4 and 8 being canonically female,I'll make Four and Eight an Inkling Boy and an Octoling Boy. You are free to share my stories,but please:DO NOT CLAIM IT AS YOUR OWN.NO ONE LIKES A THIEF! Also note:I said this was a placeholder image until I could get my friend to make one for me but I feel like it's more recognizable with this one idk.

    2nd book of my oc story series. - Lylah was lucky, lucky enough to survive until now. She could've died many times, or survive but isn't here right now. It was a horrible life in a lab of Deepsea metro. And to think there was a new test subject being created by those awful sanitized Octolings was even worst than you think. That new test subject would have to face the horrible life Lylah once had. The idea haunted Lylah so much, it hurts even more when the new test subject was somehow related to her. Escaping from the Deepsea metro was hard, we all know that. Lylah had failed mayn missions before made it to the surface. And now she would have to go back and make an escape again seemed impossible, would she do this all for the new, poor test subject? - This is an original story of my ocs(original characters) It will take place in the Splatoon world I do NOT own Splatoon, things I own is this story, the characters, the art book cover and the drawing inside this book Thank you for checking out my book, it means so much to me and please enjoy the story

    Eight once again woke up in a strange place with no memory of his previous actions that led up to him being here. He thought it was a dream. He thought he was safe at home with Four and Three. He thought he'd wake up and just had been having a nightmare. But this was reality. This was not a dream. His friends would look for him, but Eight would have left them a long time ago, to be in Tartar's perfect world.

    Nintendo own ownership to the parts which come from Octo Expansion as well as shop names, shop owners, the squidbeak splatoon and Viantastic claims ownership of the name given. Plot of story is from my own so do not think I stole it if it is similar. So same old same old, Bridgett brings down tartar and then what happens next is all in the story. Enjoy.

Part 2 (Splatoon 2): Famous Turf War Athlete Leon Finn arrives in Inkopolis Square to compete in the Turf War competition, but soon meets an unfamiliar face, which he finds delightful, and his life becomes one big adventure, that even his chaotic energy can't handle. Part 3 (Octo Expansion): A young Octoling doesn't know who he is, his only name is Eight. But when he meets Cuttlefish, his desire to escape reaches an all time high in the Deepsea Metro. When he remebers who he is, and eventually is pulled into a very threatening plan. Part 4 (Splatoon 3): A young Octoling named Paella Kani finds herself at odds, after heading to the Splatlands, she soon finds there's more chaos there than she bargained for. When she finds Alterna, she realizes that Octarians might not be the biggest threat to the world Part 5 (Side Order): Eight wakes up in a place that's completely blank, joined by a drone that seems familiar, Leon who's chaotic attitude shines on, and a new friend that's been sanitized, he goes to rescure his fellow Octoling Marina, and soon realizes that chaos might be needed to help her. (DISCLAIMER! Splatoon and its characters belong to its rightful owners, All OCs are mine. This will be a five part series with each adventure split into different chapters, at the beginning of each part, I will introduce my ocs, so you can get a grasp on what they're like.)

    An Octoling awakens deep underground, lost and suffering amnesia. Upon meeting a strange being called Cap'n Cuttlefish, they join forces and embark on a journey to return home, wherever that is. Soon, they encounter an odd telephone who calls the Octoling Test Subject #10,008 and sends him on a journey to the "Promised Land," a utopian world of light that only those who prove themselves worthy may enter. With the captain's support, 10,008, now called Agent 8, begins a quest to prove himself by completing a series of tests within the Deepsea Metro, a facility managed by Kamabo Co., and collecting the four Thangs to build a portal to the Promised Land -- home. Each test requires him to perform a certain skill, and as a reward, he receives memories of his past, piece by piece. Perhaps Agent 8 can prove his worth and make it home. Maybe he can even find himself along the way. But as the shadows of the deep reveal their true nature, he begins to realize that not all is as it seems... and his journey may be nothing more than a trap. ~🎱~ Meanwhile, Delta, AKA Agent 3, awakens far away from home after a sudden ambush during a battle with a strange Octoling boy. In a world entirely foreign to her, she sets off on a quest of her own to find her captain and return home. However, unlike her previous adventures, she cannot do this on her own. She needs help. Thus, with a partially-Sanitized Octoling hostage at her side, Delta sets her course to reunite with her mentor and find a way home... and perhaps kick a certain Octoling boy's rear along the way. She has a solid plan, and nothing will stop her from success... that is, until Kamabo Co. begins interfering with her mission and its CEO decides he has plans for her, too. She's faced armies. She's stopped a tyrant. She's even saved the world. But can she learn to trust her companion, to understand the plight of her so-called enemies, and see the strings pulled by the CEO? Or will this be how she finally falls?

    14 years with peace and quiet; 14 years with no major disturbances; 14 years of Petra being dead, Pearl grieving and the agents of the Squidbeak Splatoon dealing with minor issues. Not to mention Cora (Agent 3) and Tobias (Agent 8) starting a family, Lance and Marie getting married and so much more. 14 years of peace... Isn't that a little too long for our main characters? I think our main villain would agree with that. So what would happen if a familiar member of the huge, confusing family, reappears but as a villain, 3 people already having known about them being alive? (Theoretically) What would happen when people are kidnapped, experimented on, turned evil against their will and forced to fight their families? What if... They couldn't save those who they dearly loved, and had to watch them die? The agents would say that it's nothing new, but within the chaos of this new villain, they would all realise that this fight would be something new. This adventure was going to be different to anything else they have done in their lifetime. This adventure was going to change all of their lives, PERMANENTLY. And it all starts with Petra, better known as Keigo. ---------------------------- 4th book out of 6.5 in the 38 Saga!
