Y-Academy has completely returned back to peace. On the way to school, Mataro sees someone who looks just like Jinpei. Over-flustered from these events, Mataro also said that there was something that looked like a cat Yo-kai behind him. While Mataro makes a fuss in the clubroom about how he may be a Jinpei doppelgänger, Jinpei gets hungry and heads out to eat. Then, immediately, he meets his doppelgängar, something said to kill him if he does? Not only does the existence of Y-High School come to light, but Mazera - who they thought they defeated - appears in the schoolyard as a whole new threat!
