Abilities of Kekkei Genkai: The user can maniuplate water in whatever way he/she wants. Depending on how the user directs the water, it could be used as offence, defence, or healing.

C: Deflecting multiple objects, putting out a fire, Healing small broken bones
B: using a water-canon to break down a barrier or to knock someone a good ways off, A water dome that would deflected most fire jutsu, healing big wounds
A: Smashing through a strong barrier, water senbon needles used to kill someone, A water dome that deflects most fire, earth, and wood jutsu, healing major wounds
S: Breaking through any type of barrier, tsunamis water cannons and small hurricanes that kill people, a water dome that deflects almost any kind of offensive jutsu, healing wounds that people would usually die from.
Appearance when using Kekkei Genkai: basically....water bends to the will of the user, doing anything they wish. It is controlled by hand motions.
History of Kekkei Genkai: Not much is known about the creation of the Ekoraakei except for that it's first user was Kaida Harishikota, a kunoichi famous for her healing abilities. In the years following her death, the Ekoraakei developed more fully among the Harishikota clan. However, the bloodline seemed to weaken a bit, and it is rare that a member of the clan is able to use the Ekoraakei higher than a C rank.
Users of Kekkei Genkai: Daisuke Harishikota (deceased), Yuri Harishikota (alive), Ebony Harishikota (believed to be deceased but death was never confirmed) Kora Harishikota (alive if she gets approved)
Drawbacks of Kekkei Genkai: It takes up a lot of chakra to use, so unless you are aiming for a one-shot kill in battle it isnt a wise choice to use unless it is for defence. If you use one of the higher-ranking uses, it will leave you feeling drained.
The jutsu also has a negative effect on the chakra system, after using it for a long time or a higher rank like B, A, or S, there is a pretty good chance you will pass out (and if you pass out in a battle you will usually die).
