__Kuki's POV__
I've been training with the samurais for two years now,although I mainly trained in Kenjustu and chakra weapon techniques,my gentle fang and steel release have grown significantly due to the increase in my physical strength and chakra reserves.
I found that through honing my steel release,my natures affinities also grows making ninjutsu training way less tedious because I could just focus on grinding steel release.Over the past months,I've developed three steel release Justus.
The first one is weapon creation Justu. By manipulating my gray chakra into the shapes of weapons using the triangle hand seal,I can create various weapons out of steel.Through this technique ,I can make knives with chibi Hanabi symbols and even a big knife that's based on Zangestu from Bleach if I try hard enough.
The second one is flying needle Jutsu,using the same principles as rock throw Jutsu.I can create shape steel needles that are 10 centimeters in length and then infuse them with chakra using the technique: chakra flow before sending them flying at my foes chakra points at high speed,disabling them temporarily.
The third is steel spike Justu,I can create steel spikes that sprout from the ground to damage my opponents.This technique can be use to catch my opponents off guard to create openings for me and my allies.As of yet,I can only create 4 to 5 spikes that are 1 m in length and 30 centimeters in width.
Also,after a while of training chakra flow,Uncle Isane taught me a breathing technique called flow breathing,by inhaling quickly and suddenly and breathing out slowly,it aids the flowing of chakra in your body making you better at utilizing chakra flow.While Isane also told me to only breathe this way when performing the chakra flow technique because it puts a strain on your lungs,because that I found that my this breathing technique also help with recovering my stamina and refilling my chakra reserves,I've been trying to breathe using t flow breathing as much as I could.
At first,I felt miserable like my lungs were constantly screaming out for me to stop,after 12 months the strain was practically gone as I am able to use flow breathing twenty four seven.With this,my muscles's recovery speed was majorly boosted giving me a huge boost in physical strength.Because of my body's newfound regeneration speed,I've decided to start training with weights as it won't stunt my growth but possibly even aid it.
With steel release,I made 2 hand bracelets and 2 leg bracelets,due to being made with very condensed steel,even though they're only 0,5 centimeters in width,they weight about 2.5 kgs each so now I have 10 kgs on my body at all times.
Due to the increase in strength,I finally managed to further develop my great grandfather's original taijustu style,Gentle fang.
Third fang:devouring palm,by attacking the opponent's main chakra points,I can used the chakra "fangs" covering my fingers when using gentle fang to take chakra from my opponents and add it to my own chakra reserves,being hit by an excessive amount of this attack can cause chakra depletion.Although it's powerful,this technique won't be more than a minor inconvenience for chakra monsters like Hozuki Uzumaki.
