Yakushi Clan

Intro

Abilities
The members of this clan are famous among Kirigakure's forces for their sublime abilities in ninjutsu. The clan is very strict about the quality of their shinobis and strives to preserve it.

In order to become a shinobi, every child is trained by the clan since at a young age. During this period they must prove the can hadle Earth or Fire release, if they are not able they won't be allowed to enter to the academy and would never become a shinobi. Moreover they must possess full control of Lava release if they wat to take the chunnin exam.

Chakra
The most common chakra nature is Fire and Earth which are needed to master Lava Release. Some members develop a third nature being Water the most common and Wind and Lightening most uncommon.

They tend to possess precise chakra control, which is needed when using their Kekkei Genkai. In contrast, they rarely tend to develop physical traits such as speed or strength since the Lava Release allows them to fight at long range distance.

It is also uncommon to see a Terumī relying on weapons unless we are talking about small ones, like shurikens or kunais.

Kekkei Genkai
Their Kekkei Genkai allows them to control the many forms of Lava Release, which makes each user unique. While some can use molten rock in liquid state others master a more solid state such as rubber.

There are few Terumī's who were talented enough to master the lava that lies under the ground instead of molding the chakra inside their bodies. Unlike other natures like water, manipulate the existent lava is a very complex thing to do since it's located deep down in the ground.
