Jace is a normal squid in the city of Inkopolis. But when he meets another inkling called 'Agent 3' his whole life changes around him. He gets accepted into an academy designed to train squids for battle and he unfolds hidden plans to take over Inkopolis. It's time to save his home.

Chiro travels to Inkopolis to live a normal life. However, he is thrown into many difficult situations as he meets many formidable Turf War players that belong to the strongest group in Inkopolis, the Elite 10. To make things interesting, Chiro has a unique hair color: white, and doesn't know a thing about Turf Wars before meeting a girl named Vivi. Some suggestive stuff.
