T-Dine and DS Galaxy have also evolved, and the Yo-kai Heroes and their friends join forces to fight Mazera Bolt to the death. And Earth Walker NOA Armored, which gained the root of the great power by the "New Yo-kai World" regenerated in its body, evolved into a true final form "Black Cat", and was able to get rid of Mazera Bolt's whole body in just one blow. Black Cat gathers power and finally destroys Mazera Bolt. Finally, when they try to destroy the black hole that is Mazera's real body with the planet destruction missile "Hakaiya DX", it was discovered that the main engine of the Hakaiya DX had been destroyed by Mazera Bolt. They can't beat Mazera at this rate, then Mataro proposes something.
