The Yo-kai Watch Shadowside anime is set thirty years after the original anime series, and takes place shortly after the events of The Return of the Oni King. The series focuses on the main characters of the movie, who are known as Natsume, Touma and Akinori, who solve mysterious Yo-kai related incidents together.
In addition to them, Natsume's younger brother Keisuke, who only played a minor role in the movie, joins the main cast of the series, being it's fourth major protagonist.
Compared to the original series, Shadowside is a lot more plot-driven and serious in tone, while it still retains the sense of humor, and aims to cause widespread appeal across all age groups. The episodes are also all singular 30-minute episodes, compared to having one-to-four segments in the episode runtime.
