Whisper

Whisper is one of the central supporting figures and mascots of Yo-kai Watch, serving as Nathan's self-proclaimed Yo-Kai butler. He helps Nathan by explaining the Yo-Kai Watch and providing information about the Yo-Kai they encounter.

Whisper's characterization varies by version. In the manga he is polite, uptight and proud of his Yo-Kai knowledge, while the English-dub anime presents him as more oblivious, sarcastic and prone to denying Yo-Kai explanations. His ghost-like form also allows him to pass through solid objects.
