A dark power has ignited a war between two groups of Yo-kai: the bony ghosts and the strong spirits. As a result, the entire world is plunged into chaos. Nathan and his friends must travel through time to uncover who is behind the sinister plot. Could these two strange Yo-kai be involved? Befriend over 350 amazing and recurring Yo-kai, each with a unique personality. Travel by train to fantastic cities where great Yo-kai await. Team up with a heroic cat named Hovernyan and journey back in time to save Lenzhausen and learn more about the origins of the Yo-kai Watch. Mysterious Yo-kai can be cool, cute, or creepy—and most of them are quite the tricksters. They live invisibly in the world for most people and cause all sorts of trouble. You can't see them, but they are everywhere: under cars, behind vending machines, and even in rivers. With the power of the Yo-kai Watch, you can track down these invisible troublemakers. You might even befriend them. There are over 350 Yo-kai, each with a unique personality, including 100 brand new Yo-kai, some of which can only befriend you in one of the versions. Now there is a Yo-kai Watch - Model Zero. This upgraded version of your reliable Yo-kai Watch offers great features like the powerful M-Power technique and the ability to poke opposing Yo-kai in battle. For the first time, you can now battle with friends over the internet. You can also trade Yo-kai medals and team up for a cooperative multiplayer game in "Yo-kai Watch Blasters" mode through local play. Challenge friends in a local game or - for the first time in the series - over an internet connection. Earn points that you can exchange for in-game items.
