The day where Zero returns is now. Worse, it on the planet Earth... except he has turned into a creature called a Cocotama. Cocotamas are tiny gods born from objects, and they need to train to master their godly powers if they want to become true gods. So it's up to him and some oblivious Cocotamas to get his powers back and continue destroying them all without the others knowing who he truly is, AND avoid being spotted by humans or else they will die.
Will the oblivious Cocotamas find out who he truly is and stop him? Or will Zero destroy this planet and move on to the next? Or...?
