Across the ocean on the tiny island kingdom of Barou the ancient god Neo Ranga awakens from his slumber. He is mysteriously drawn to Tokyo, and the three beautiful sisters - Minami, Ushio, and Yuuhi - who are unwittingly linked to the monster.

But instead of rolling out the red carpet, the military rolls out the weaponry, and things start to get nasty. The plot thickens: Why is Neo Ranga driven to Tokyo? Is he a messenger with a warning for humankind, or just a big boy out for a good time? And what's behind Ranga's mysterious eyes?
