Fuyunyan

フユニャン

A blue cat Yo-kai featuring a white chest, muzzle, and paw tips. His nose and inner ears are a dull pink, and his facial expression contrasts with that of most other Cat Yo-kai. A white scar is located at the center of his forehead. He wears a dull gray belt adorned with a swirled sphere, along with a long red cloth worn as a cloak.
Fuyunyan possesses a very righteous personality, frequently doing what is right and standing up for his friends. He is shown to be very patient, though after a while, he can lose focus on the task he is given. He is also very embarrassed about becoming Dekanyan. He tends to act very childishly, as seen in the movie when he introduces the "Rewind Stone" and makes his own sound effects. He has strange ways of doing normal things.
Fuyunyan has the ability to fly, and in the movie, he throws balls of energy and coats his fists in it.
When Keita and Keizou borrow all the other Yo-kai's strength, Fuyunyan is transformed into his grittier, more powerful version, Darknyan.
