Henshin Onibue

The Transformation Demon Whistle Onteki (変身鬼笛・音笛) is a whistle-like transformation device which gives Ibuki the ability to transform into an Oni, using special sound waves. He blows into the whistle and places it in front of his forehead forming an Oni face. He swishes his arm around summoning a whirlwind around while he transforms.

In addition, the Onteki can also playback the sound data collected by the Disk Animals.
