Henshin Onsa

The is a transformation device resembling a tuning fork. It is the most commonly used transformation device among the Oni Kamen Riders of the organization Takeshi, usually those whose arsenal revolves around the percussion.
==Design==
It is said to be the simplest of all transformation devices to make, yet has the capability to unlock the greatest power within all Oni that use it. It has two forms: 'cellphone mode' and 'tuning fork mode'. While in the form of a cellphone mode, its Oni's face can not be shown, and the two prongs should be flipping out to reveal it. Furthermore, the Oni symbol is at the end of the holder, and the device is placed on the right side of the belt.

*An Oni's transformation device, especially for percussion-type Oni. There is also another type of Oni that uses this device to transform.

*Onsa can also playback the sound or video data collected by the Disk Animals.
*The design is like a mobile phone, where Oni needs to open it just like that electronic device when using it, it also has a kind of ringtones that will ring when Disk Animals returns from its investigation.
*It also has a function to call Disk Animals without waiting for their return. Oni needs to 'open it', tapping it, lifting it to the forehead, then pointing to the direction where the Disk Animal is released (example: sky for Akane Taka, water surface for Kihada Gani, etc.). Next, Oni made an interesting signal twice.
