|
- Device Type: Tuning Fork
- Other Forms: Echo Sword Onsaken
The Transformation Tuning Fork Onkaku (変身音叉・音角, Henshin Onsa Onkaku) gives Hibiki the ability to transform into an Oni, using special sound waves. He taps it on a hard surface and places it in front of his forehead forming an Oni face. Purple flames engulf his transformation into an Oni. In addition, the Onkaku can also playback the sound or video data collected by the Disc Animals. During the events of the movie, the earlier model can be used as the Echo Sword Onsaken (鳴刀・音叉剣, Meitō Onsaken)
