Begin Again - Chronicles of an Ex-Human In Inkopolis
Lily is an odd Inkling who's learning to live in the big city of Inkopolis among other marine life. She's also ex-human, after being flung far into the future from her own time. But it's hard to keep a secret like that from the New Squidbeak Splatoon, who found her, Off the Hook, who think she's connected to the NILS facility, and DJ Octavio, who wants her and her history for himself.
In the aftermath of Agent 8's battle against Commander Tartar, the phone on the Deepsea Metro has shut down - along with another facility lurking deeper beneath. Subject One's entire life has been spent alone there, taught by the speaker, but now, left with open doors and without guidance, the experiment is free to explore the world outside the test centre - and discover what it means to be alive.
