Byakugan

It is the Hyūga’s kekkei genkai, which grants a good number of abilities to the person who develops them fully, it is one of the four great dōjutsus and is known as “The All-Seeing Eyes”. The Byakugan has three levels of evolution, with the third level being the strongest.

Abilities
In the first level the user gains access to a 359º vision with a blind spot, being capable of seeing through things to a limited distance and see chakra like the Sharingan third level can, meaning Byakugan users can detect genjutsus as well. In this level the Byakugan is completely white with pupils outlines only.

With the second level the distance the user can see is quadrupled, being also able to see most of a chakra network, but not being able to see chakra points just yet. In this level the Byakugan has white irises and lavender pupils.

When the third level is reached, the distance the user can see is immensurable, being able to see the chakra network completely with chakra points as well, the user also unlocks a complete 360º vision without blind spots. In this level the Byakugan has lavender pupils and light lavender irises.

Evolution
If any bearer of a mature Byakugan receives pure chakra in their system or if they have Hyūga and Kaguya blood, it's possible to awaken the kekkei tōta of the Hyūga Clan, the Tenseigan.
