Omniyogan

The Omniyogan (Literally meaning: Anywhere But Eye) is the dōjutsu kekkei genkai of the Okayado Clan that appears commonly among its members. As the Okayado Clan is commonly addressed to being nonexistent the eyes origin is "nonexistent". Its independent form was first manifested by Ryun Okayado.

Acquisition When a wielder of this kekkei genkai experiences a considerable amount of pain, anger, courage, fear, stress, sadness, loss, or dread, their brain releases a special form of chakra that affects the optic nerves, transforming the eyes into the Omniyogan.

It was shown that normally after first acquiring this dojutsu, the user will without a doubt pass out from their body trying to keep up with the Omniyogan's power. T he user is aware they have awakened the Omniyogan after they first awaken it because their vision is said to be "equal to if not, greater than a hawk's" and they are thereafter able to freely use it. When first awakened each Omniyogan usually will be orange and veins will become prominent on their forehead. Through more training (and some of the experiences above) and continued use the Omniyogan will develop a row of tomoe and then, upon full maturation, go without pupils. All the Omniyogan's basic abilities are available to the user from its earliest stage, but with greater development comes the more advanced basic abilities.

As with any dojutsu , Omniyogan can be transplanted into non-Okayado.   They are unable to deactivate it and its use has a greater chakra demand for them than for actual Okayado, who need only minimal chakra to keep it active. For these reasons, non-Okayado tend to cover their Omniyogan when they aren't using it in order to conserve chakra.   Omniyogan that originate from the same Okayado are still linked to some extent even when wielded by separate users, at times enabling those users to see the same things.

Evolution

 * The Omniyogan can be evolved into the Tenrei Omniyogan  by experiencing the near deletion of a healthy mental, physical, and emotional state, granting unique, user-specific jutsu in addition to the Omniyogan's standard abilities. Awakening the Tenrei Omniyogan will automatically mature a Omniyogan if it isn't already.


 * ​Use of the eye for too long can cause the eye to close for a long period of time. However, users of the Byakugan and Sharingan can replenish the eye via Chakra Transfer.
