This series has the second shortest amount of episodes, ending with just a total of 49. With the first being Yo-kai Watch!, which only has 36.
The series takes place after the fourth movie whereas the fifth movie takes place 80 years prior to this series' events.
Unlike the original series, this one does not have separate segments per episode. Instead, each episode has one ongoing story.
Similar to the original series, the voice actors for the main trio (Nate, Whisper and Jibanyan) still work together in this series in order to do the voicework for Tate, Shadowside Whisper and Junior, respectively.
Of all the Shadowside Yo-kai, Whisper is the only one whose personality did not drastically change from the one in the original series.
