Since i'm in the Medical field, i would love to have medical related justus and other KKGs..
i want the ability to use all five chakra natures and the a unique KKG which enables me to combine Fire, Earth, Water and Wind chakra element together and get 3 KKT..
First: Fire, Earth and Water = Naiyaton (Diamond Release) - techniques are similar to Crystal release but is composed of unbreakable diamonds whose molecular bonds are so strong, they can even be broken down by Jinton..
Second: Earth, Water and Wind = Saikinton (Spore or Bacteria Release) - ability to create microscopic sentient spores can can perform a multitude of things such as (producing antidotes for poisons or breaking down organic matter).. most deadly is the Saikinton: Raifurīchi No Jutsu (Spore Release: Life Leech Jutsu) which once inhaled by an opponent ninja, the caster can utilize his opponents chakra in any way he can so meaning, he can perform jutsus at his opponent's expense (note: this jutsu affects any chakra producing conduit may it be organic or inorganic)..
Third: Fire, Earth, Wind: Jinton (Dust Release)
I would use my Raiton Element as The Body Flicker and as the same time, being a talented medic nin, i can also utilize the Byakugou seal as well as the Creation Rebirth Jutsu and Strength of A Thousand Technique.. The pinnacle of my medical ninjutsu is Nimpo: Fukkatsu No Kami No Jutsu (Ninja Art: Resurrection of God Technique) -- which allows me to reconstitute myself from even a single cell after i have activated this jutsu. This however would shorten my lifespan in general by the amount of body mass in kg per .00008 seconds.. (do the math) lol
