If Kuroto has to choose between Rank-A and Rank-B Jutsu, then he thinks that Rank-B Shadow Clone Jutsu and Rank-A Multi Shadow Clone Jutsu would be most useful for him.
For a ninja specializing in taijutsu, the Shadow Clone Jutsu can instantly double the combat power, and if used properly it can often have a miraculous effect in the battles.
And according to his guess, there must be a collection of Shadow Clone and Multi Shadow Clone Jutsu in the libraries of the Hyuga Clan.
Therefore, Kuroto had actually planned to ask for the favor of Hyuga Hizashi in learning these Jutsu after providing the vote of confidence for the member of the main branch in the Jonin assessment.
However, he never thought that his plan could not keep up with the sudden changes, and now it was already too late to make a request from the Hyuga Clan.
Despite this, he still didn't want to use the opportunity that Hokage-sama has provided to learn Shadow Clone Jutsu.
This time the opportunity is too rare, it can be said that this is the best chance for him to get into touch with Fuinjutsu openly.
As for learning Shadow Clone Jutsu?
Asking Shisui's help on this matter would be most reasonable.
Shisui owes him a favor for helping out with the matter of the Uchiha Clan so, passing a mere Rank-B Shadow Clone Jutsu shouldn't be big deal, right?
After making up his mind, Kuroto said in a deep voice, "Hokage-sama, I hope to learn advanced Fuinjutsu!"
Hokage-sama frowned hearing Kuroto's request, "Fuinjutsu!?"
The practice of Fuinjutsu has extremely high requirements. If someone doesn't specialize in Fuinjutsu from childhood, then they often need to reach the level of an elite Jonin to successfully start learning it.
Fuinjutsu not only has high restrictions on the chakra volume of the practitioner but also chakra controlling ability.
Some parts of Fuinjutsu even requires a ninjas mental strength to be very high or having some sort of Kekkei Genkai, in simple terms practicing Fuinjutsu has a really high threshold, this is one of the reasons why Fuinjutsu masters are regarded highly.
So, after hesitating a little at Hyuga Kuroto's request, he finally nodded.
After all, it is up to the person himself to choose what Jutsu he/she wants to learn, and even as the Hokage, he doesn't have much reason to interfere in the personal interest of his subordinates as long as it is not harmful to the village.
So, after conforming to Kuroto's request, Hokage-sama turned to look at Might Guy and Uchiha Shisui.
Guy gave up the opportunity to learn advanced Jutsu without hesitation on the grounds of concentrating on Taijutsu style combat.
Sandaime-sama nodded approvingly to Guy.
Precisely because Guy's entire focus is on taijutsu mastery, he becomes 'Konoha's Blue Beast of Prey' and one of the few ninjas who can threaten Uchiha Madara in the 4th Shinobi World War.
Shisui, being a member of the Uchiha has no shortage of Rank-A and Rank-B Jutsu either, so initially, he also thought of giving up this opportunity to learn any advanced Jutsu, however, Kuroto has chosen to learn and if both he and Guy gave up, it would be a little embarrassing for Kuroto, so he randomly opted for a Rank-B Fire Release ninjutsu.
With all this decided, Kuroto and Shisui followed Hokage-sama to the confidential database located under the Hokage Office.
On the way to the confidential database, Kuroto observed every detail with the Tenseigan.
'There are Anbu guards at the corners leading to the basement on the first floor. Two members on each spot, a total of four people. Judging from their Chakra volume, they should be Chunin class.'
'There are sealing technique engraved here, one, two, three… five in total, hmm, these seals should be induction type, if the person entering doesn't have Hokage-sama's chakra signature, or whatever is used for identification, these seals should activate…'
'Hum? There are more seal techniques engraved on each stair step, they kind of look strange, not like the Uzumaki sealing techniques…!'
Kuroto was observing and analyzing all the possibilities of sneaking in.
The overall security of the Hokage Building isn't as strict as one would expect, this may also be due to a shortage of manpower in the village.
Leaving aside the working staff in the Hokage Building, there are probably a dozen Chunin guards on the bright, while there are only four Anbu squads and Hokage-sama's personal guards protecting the Hokage Building from the shadows.
Although the number of guards is small, with Sandaime-sama himself present here, there probably is no need for many individuals.
After all, if someone could bypass Hokage-sama himself, then no matter how many guards there are, they would all be pretty useless.
Moving along the stairs, the three arrived at a door under the leadership of Hokage-sama.
At this time, Sandaime-sama quickly made a few hand seals and then pressed one hand on the door.
...Click...
With a clicking sound, the door slowly opened.
"Come in!"
Giving this instruction, Sandaime-sama took the lead in entering the confidential database room.
As soon as he entered the confidential database room, he couldn't help but sigh… 'The underground database is so much larger than I expected, it goes to show just how much secret information, knowledge, and Jutsu are hidden here!'
Calming his emotions, Kuroto observed Sandaime-sama; skillfully shuttle through the rows of bookshelves, and quickly took out two scrolls that he passed to Kuroto and Shisui each.
Shisui randomly selected a Rank-B Fire release ninjutsu that he didn't know from the scroll and silently stood on the side.
While Kuroto carefully observed the seal, techniques recorded in the scroll.
There are many seal techniques he could choose from, including the Five -elements seal, Four-Symbols Seals, Eight-Trigram Seal, Contract Seals, and so on.
After much deliberation, comparison, and repeated observation, Kuroto found that among these sealing techniques Four-Symbol Seal was the best for him for now, so after a little more consideration, he opted for Four-Symbols Seal.
Sandaime-sama nodded slightly, and then put away the introduction scrolls.
Then from the bookshelves on the front, he selected a scroll that separately records the Four-Symbols Seal along with a scroll of the Rank-B Fire Release ninjutsu selected by Shisui and passed them to Kuroto and Shisui respectively.'
Sandaime-sama also reminded: "The Jutsu you are learning while in the Anbu cannot be passed out to others, both of you should be aware of this!"
Kuroto and Shisui both nodded, of course, they are aware of such rules.
Additionally, "Turn in the Jutsu scroll within 1 month. While you are on official missions, this time will be postponed, and if you encounter an accident, make sure to destroy the scroll and never leak it!"
"Yes!"
With Hokage-sama's nod, both Kuroto and Shisui left the Hokage Building.
As soon as they came out, Kuroto talked about the Shadow Clone Jutsu with Shisui.
However, SHIsui was stunned and looked strangely at Kuroto.
And, why wouldn't he be stunned?
From Shisui's perspective, with Kuroto-san's strength, being able to kill the elite Jonin of Rock Village as well as the fight and suppress the Demon Moryo, Shadow Clone Jutsu should have been mastered long ago…?
Anyone with a little bit of brain and necessary chakra level will at least master it, even if they don't use it much.
Even Kuroto was feeling a little embarrassed about it, obviously, he can't tell Shisui that he was just a cannon fodder class ninja until a few months ago, where can he learn such important Jutsu!
All he could do was to come up with some excuse to hide this embarrassment…
