    Messed up book smfh Currently under edits of bad grammar (don't judge. I apparently made this book like four years ago) ⚠️includes spoilers of Octo Expansion⚠️ Read at risk lol 😂 (Ten thousand years = an update ٩( ᐛ )و ) Apparently on a last chapter+cliffhanger, so if you want better and regular updated books, go and find the others, they're better than me. My home language isn't English okay ._. I might come back to finish this but eh, maybe when Splatoon 3 is out and I'm back in the fandom :')

    Just general ideas I have for fics, if you want to make one of these a fic you can, just give me credit and/or ask first. There will be multiple chances for you to help decide where the story will go and add characters or fic requests if you think I'd like it so comment where ever if you have some good ideas. The tags will be added as I go, look at them for a look at what fandoms I have on here.

    It has been 5 months since the events of Splatoon 2's main campaign and the Octo-Expansion incident occurred. A young girl by the name of Niko is one of many Octarians that moved to Inkoplis. She is currently working for Inkoplis news as a photographer with her Inkling best friend Luna and their mean yet caring boss Joey. Their way of life is broken however when strange occurrences start to happen across the city, multiple innocent people start to go missing and no one knows why. Niko and Luna, suspicious, launch an investigation focused on figuring out what's going on. What they find is not only monstrous, but unholy.

    This story takes place before, during, and after the Octo Expansion, so there are obvious spoilers ahead. Pearl and Marina have been dating for about a year now, having been together as Off The Hook for about two years. They also still haven't made their relationship public. One day while walking around, they find a walkie talkie.

    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

    What if the blue team had childhood friends? And that these friends of theirs were a family of Inkling and Octarian hybrids. These hybrids were from a long line of historians, chefs, architects, and others who are philanthropists. After years of being away from each other, they reunited in a series of events involving a shady corporation. Fun fact: philanthropist means 'lover of humanity.' Splatoon belongs to Hisashu Nogami and Nintendo. The manga belongs to Sankichi Hinodeya and CoroCoro Comics. Also, I was inspired by Tailsfan1996's Splatoon manga story.
