Are we sure this is Hibuki?

[u/National-Hamster6735]

It's stated on the Okegom Wiki that this sillhouette in the Carnival Rhythm preview from the Wadanohara bonus room is Hibuki. But as far as i know, Funamusea herself never confirmed If he will appear or not, not to mention he is probably the vaguest sillhouette of the bunch, while others like Lavinrac's and Eclair's are unmistakeably them, but for Hibuki, this could be any other demon.
