Humanity's Historic Homecoming

For a Human-less Earth, the Mollusc Era is proceeding brightly. Yet, right as relations between the dominant Inkling and Octarian races are going well, visitors from beyond perform a not-so-smooth landing. Though these uninvited guests seem completely alien, the shocking truth becomes clear; that these aliens are, in fact... not so alien at all.

The past, future, flesh, metal clash as the New Squidbeak Splatoon piece together a story from the stars, defend against a celestial foe, and determine if there's still room in their world for Earth's long-lost children.
