Isle of Onogoro

Following the Seed from the Tale Foundry Contest:   'There have been creatures hiding in plain sight among the populace for centuries, but only now are the people becoming aware. They must race over the course of the next week to prevent the catastrophe that will result from their discovery.'   To become:   What happens when the being of a Semi-mythical Japanese Island have to deal with secret invaders from the other side of the planet? A race against time and a whole lot of clashing cultures, that's what!
