Yo-Kai Watch 4 takes place in four different worlds connected by mysterious gates: Keita's World which is very familiar to fans of the series, Natsume's World which stars Keita's future daughter Natsume 30 years later, Shin's World which is based on the Forever Friends movie and takes place in the 1960s, and the Ghost World which is headed by the Great King Enma.
