''KARA??'', I said with a surprised tone, from what I know they are a powerful organization but they don't even appear on the story until Boruto is born and finished his academy days.
If this is the real KARA then I will have a helluva fight before me, if am not mistaken Jigen was able to defeat both adult Naruto and Sasuke and this was before he resuscitated on his body, yep apparently is quite a pain in the ass to kill an Otsutsuki, they can mark you With Karma that functions like a conscious and DNA back-up so if they die they can revive given then some time.
But at this time Jigen haven't found Kwaki so he shouldn't have a Karma drawn yet, but even with his current body that isn't a total compatible one, he can still defeat adult Naruto and Sasuke besides having a different Dojutsu that permits him to shrink things, see DNA and a bunch of other wacky stuff, this is everything he can do + yes he still comes with a bunch of other dangerous skills.
Jigen as Isshiki's vessel, has a body that is able to channel the various abilities of the Celestial Being. He can produce black rods capable of draining chakra from the victim and can also shrink matter to microscopic levels and just as easily return it to normal so rapidly. He can also manifest various stored objects from a pocket dimension, which he can perform with the most minute of gestures such as a mere wave of his hand or even just a flick of his fingers. He utilizes these abilities to launch the black rods at microscopic size into the bodies of his foes while leaving them completely unaware, before returning them to their original size to instantly inflict catastrophic injuries. He can also enlarge them whenever necessary to counter armed blows from enemies. He can also apply the ability to his own body, allowing him to disappear from sight and maneuver around the battlefield, as if teleporting, fast enough to catch the likes of Naruto and Sasuke off-guard. The limitations of this ability remain unknown, but Sasuke was able to track his movement even at a microscopic level thanks to the Sharingan. Once activating Karma's full power, Jigen became able to use these abilities at an even greater level, able to spontaneously summon large black rods instantly to incapacitate Naruto and Sasuke and even form them from his neck to block Sasuke's sword attack. All of this besides having the already op abilities of Karma(Can absorb and sent back ninjutsu and a bunch of other wacky stuff).
The third Hokage was able to get me out of my musing by continuing with his speech '' We were able to detect this name being called a lot of times during ou investigation but whatever did it is meticulous and is becoming better with time, the only paper trail we found was pretty old so we have some clues right now'', seeing my relieved and preoccupied face the Hokage continues '' But don't go running there this trail could be a trap to so I would like to investigate a bit more before we take action''.
''I understand Hokage-sama, I will try my best to help with utmost caution'' the Hokage seemly satisfied with my answer dismissed me saying we will discuss more our plans later. but I have an idea.
My idea is quite simple actually, my [Observation Haki] has reached such a magnitude that I can expand it beyond the fire country, a pretty big range, but the problem is the sensory overload, no matter how much of monster I am it will take time to be able to see an entire country worth of info into my head at the same time, so can try to sense some abnormalities maybe I can do it. My doubts are not unfounded, the first time I used my [Observation Haki] to the max (Without unconsciously holding back), I almost died of brain damage if it wasn't for the [Sage Body] I would be already brain-dead.
I've done a bit of info dump here, I picked up some parts of the wiki to not say something strange.
The other thing I have to say is that Boruto manga is surprisingly pretty good, is way better than it's shitty anime version.
