Hiraishingan

Acquisition
The is a Kekkei Genkai Dōjutsu that is passed down through the Kyuuba Clan. Every member of the Kyuuba Clan is able to obtain this eye, but it is very difficult to do so.

In order to obtain the Hiraishingan, one must first have the Yoruhigan. Once someone has the Yoruhigan, they must do the following:
 * 1) Have the Yoruhigan active.
 * 2) Be struck by naturally occurring lightning OR be struck by Kirin.

After this has happened, the Yoruhigan will transform into the Hiraishingan.

As with any dōjutsu, the Hiraishingan can be transplanted into a person that is not part of the Kyuuba Clan. This is not without consequence however as doing this will change a person's chakra affinity to Lightning Release and immediately send enough voltage through their body to stop a human heart, and may fry the person's brain. If successful, the Hiraishingan will work as usual.

Abilities
The Hiraishingan retains the abilities of the Yoruhigan in addition to granting two new abilities. These are known as Full Body Lightning and Thunder Blood.


 * "Full Body Lightning"
 * 1) From the instant the Hiraishingan is acquired, the owner will gain a powerful electric current inside them that flows through their entire body. This current is strong enough to kill most people but will become a normal part of the owner. As a consequence of this, the owner's chakra affinity will become Lightning Release, unless they already have this affinity. The electricity in their body will make Lightning Release Techniques, and any combined Chakra Nature Techniques that include Lightning Release like Plasma Release(Ender), much stronger.


 * "Thunder Blood"
 * 1) As part the second ability of the Hiraishingan, the eye is permanently active but does not drain extra chakra. Because the eye is always active, the owner of the Hiraishingan will become immune to Lightning Release, though Combined Nature Transformations using Lightning Release will still harm them, and any Lightning Release Techniques or natural lightning will be absorbed by them on contact. This electricity is stored within them and can be used to power up their Ninjutsu.

Transformations

 * There are no currently known transformations for the Hiraishingan
