Kekkei Genkai
A special trait related to a blood heritage
These are unique techniques or abilities that depend on genetic factors. A Kekkei Genkai grants various abilities to its heirs, who now have powers far beyond those of common people. When someone with a Kekkei Genkai acquires a ninja technique, its effect may be unbelievable...!
Some Kekkei Genkai...
Up to volume 14, three Kekkei Genkai have been identified, each one with extraordinary abilities and impossible for normal people. Not only that, what was revealed of these powers thus far has only been the tip of the iceberg...
Byakugan (White Eyes)
^ Allows for looking through objects and also the keirakukei, that is, the vital lines that move the chakra through all the body.
Sharingan (Copying Wheel)
^ Grants the user great awareness, hypnosis and the ability to copy techniques.

^ Haku's Ice Crystal technique lets him move from one mirror to the next at the speed of light.
The tragic fate of those who have special abilities...
Haku's clan had extraordinary powers; due to that, they were manipulated by the powerful men of the Water Country, who used them as weapons of war. The fighting reached such a point that the nation was ruined and the clans bearing Kekkei Genkai were humiliated and accused of bringing death and destruction. To protect themselves, they started hiding their lineage and lived afraid of being found out.
v> Haku was almost killed by his father due to his lineage...
Clans with special powers in the Hidden Leaf Village...
In the Hidden Leaf Village, the clans bearing Kekkei Genkai live normally, unlike in other countries, where it's hard to survive without hiding your lineage. In fact, the Leaf Village folk respects and fears the clans that inherited special abilities and considers them elite ninja.
Inheriting your powers also depends on luck
Even if the parents have a Kekkei Genkai, nothing ensures their children will inherit the same power. Not only that, there's no way to know when or how much power will awaken within oneself. There are no rules for Kekkei Genkai and it depends on luck.
< The Sharingan inheritance is rare even among the Uchiha clan.
^ The branch line overcame the main line. He learned Hiashi's technique on his own!
