A long time ago in a faraway land, strange little creatures lived in the depths of Abyss.
Cocoto, his little devil friends and the mysterious Fairy protect the secret of the magma — the source of their power — in a magic cauldron. Meanwhile, Zaron, the god of lightning who lusts after this force, is up to something. He can count on the rulers of the other kingdoms that Cocoto must cross.
The tragic kidnapping of Shiny, Baggy and Neuro has left Cocoto alone to watch over the cauldron. Refusing to leave his friends, he will set out to find them with Fairy.
