It will follow the events of the latest movie
The official website for the Yo-Kai Watch anime has announced that an anime that follows the movie “Ko-Kai Watch Shadowside: The return of the Oni King” is in the works and will premier in April 13.
Anime News Network describes the story as follows (with a slight modification from yours truly):
“The series is set after the events of the Yo-kai Watch Shadowside: Oni-ō no Fukkatsu anime film, and will center on the character Keisuke (Haruka Tomatsu), the younger brother of Natsume. Natsume is the daughter of previous protagonist Nate and she was the protagonist of the film. Keisuke is a fifth grader who does not believe in ghosts, UFOs, or even yo-kai. Lately, he has noticed that Natsume has been coming home late, and one day decides to tail her. When he discovers that Natsume goes to a yo-kai detective agency, Natsume is forced to involve Keisuke in her activities.”
Personally... I am Hyped for this series.
