It should be uood that while I was certainly not the only sage to exist in Konoha si's founding I was the only oh enough sage chakra to possibly pull off something like this. For all the es of Konoha(which was the First Hokage and Jiraiya) sage mode was sort of like a temporary boost and burhrough their chakra at a rapid rate. For me however I had always been in sage mode and thus teically didn't burn my chakra to maintain it as it was my natural state.-

  I also had enough chakra to match a tailed beast drop for drop all the to the ails. This was both a boon and a curse as so much chakra also meant that if I didn't suppress it within my body the leakage alone would be enough t most in to their knees out of suppressive weight alone. In this case though my chakra pool was a boon as it meant I could effectively work as the battery for the new barrier that stretched over the entire vilge. -

  Obviously not permaly but just during the stru phase of the barrier where the most chakra was wasted. I ended up sitting cross legged in the ter of a seal formation radiating my chakra passively while I meditated.

  "How you holding up brat?" My sensei asked worriedly.

  I opened my eyes and smirked "You may want to tell them to up the drain, I regee the stuff faster than this is taking it." I said smugly.

  "Of course a monster like you would say that, I don't even know why I thought this would make you unfortable at all?" she said with a roll of her eyes.

  "Jokes aside you sure this is enough to work with? If we are doing this I'd like it to be the best possible so o be siderate, take all my chakra if it'll make it stronger." I said seriously.

  "Are you sure about this Kenzo?" she asked seriously.

  I nodded "Yes, lets make a barrier unlike anything the worlds ever seen before." I said with a grin.

  She nods before turning to the group of seal masters w nearby "You heard him, he wants better than your best so make it happen!" she anded and the seal masters took on expressions of determination as they got to work.

  The results of my decision became clear immediately as the drain increased dramatically and finally exceed my regeion by a smidge. This alone shocked the seal masters as well as my sensei because the current drain was enough to turn ae jonin to a shriveled corpse in ten minutes but was BARELY more than my natural regeion of chakra. I was also surprised by this as I likely never would have discovered this aspeyself without this endeavor. Jutsu were sort of oime payment things so anytime I used one I barely felt the amount of chakra needed for them.-

  Due to this finding my actual rate of chakra regeion was rather difficult as I had never had enough of a drain to accurately measure it. While I was gd to finally uand this I couldn't help but feel a bit embarrassed at the envious looks I got from my sensei and the seal masters. While I felt the drain from the formation I had the brilliant idea to begin experimenting with my chakra armor since I'd now have a poteernal source "attag" it. -

  My sensei just looked at me speechlessly as the bright blue chakra struct maed on my body in an unstable manner as the chakra it was made up of was rapidly being ripped away by the formation. I merely grinned and worked to stabilize the armainst the pull of the formation which proved an excellent idea as I was forced to extend the armor over my feet to stave off that oint. Holy this only worked because I deluded my body into thinking I was in a life threatening situation and thus had it pulling out all the stops to save me.-

  'All that's left is to extend the armor over my head and the teique will finally be plete. Best to leave that for when I am not getting drained of chakra so aggressively.' I thought satisfied once I got the hang of c my full body in my chakra armor.

  "From the looks of it you should have the moniker "Konoha's blue beast" rather than Might Guy." my sensei said and I shook my head.

  "I'd rather not have any mo all if I help it, if I joined a battlefield it'd be bullying at this point." I said holy.

  I meant it too as whether it was my chakra reserves, jutsu repertoire, taijutsu or physical durability I was o impossible for ao matot even chakra metal pee my skin so I could literally stand still in the middle of the average shinobi army and take no damage at all. If I fought back I was literally an army of one as I could route aire army by myself. I included the general of that army as well that was either an S rank h elite jonin historically.-

  I had tingly admit that I was an S rank threat at this point simply due to my unkilbleness. There was no other way to see it as the most dangerous sort of shinobi was the ohat wasn't afraid of getting hurt. Sure it could be argued that destructive capability was also an important factor but what's more threatening. A shinobi that burhing for miles but be killed with a kunai or ohat burn a smaller area but is practically immuo physical damage and all jutsu up to S rank?-

  In a short frontation easily the first type but in a long drawn out affair like a battle the sed wins hands down. I roag a perfect fusion of both types as my rge area jutsu were also quite powerful. So yes I was an S rank shinobi and acc to my sensei easily the hardest to deal with for anyone who wasn't the Third Tsuchikage Onoki. Dust release was just that dangerous and not even my defenses were likely to stand up to it at all. I certainly wasn't going tue this fact either knowing how dangerous Shiro's ability that was on the same level was.
