There used to be a boy who could control Yo-kai with a mysterious watch. However, he became unable to see Yo-kai when he became an adult. With the boy's duties finished, the watch was buried away in space-time. Then 30 years later, quiet everyday life comes to an end as a fateful day beging with a comet drawing near. The terrible Yo-kai virus Onimaro infects people's malevolent intentions and spreads infinitely. The one chosen by the Yo-kai Watch is the one who can save humanity from its crisis. The bond between humans and Yo-kai may be recovered with the attainment of a new Yo-kai Watch.
