the conclusion
"Katon: Gouka Mekkyaku" Luckily this Jutsu is just a normal type release and Kaoru has seen this Jutsu in his previous life.
so, what Kaoru demonstrated now is not a replica or a rip-off technique like his Gaebolg or other noble phantasm.
this world has chakra so using a Ninjutsu actually is easier but sometimes you want to act cool like those wizard or mages that always say cool or chant to use their power.
Orochimaru who got attacked by such a Jutsu turns frantic, he never thought a person who would use a high-level fire Jutsu inside the forest existed.
he even started to question Kaoru's sanity, whether this guy has some screw loose in his head or not.
"What a crazy kid!" Luckily he still could escape by discarding his fake body and transforming into a small white snake.
but before he could walk far he received a telepathic message.
'Sensei said he wanted to talk about business with you, he is waiting at the tower' and the message ended just like that.
-------
after making sure Orochimaru is gone and the kids are saved Kaoru asks Ino to send a telepathic message to Orochimaru.
"Sensei why do you want to make a business with that traitor?" Ino feels Kaoru has some hidden agenda and she believes him, but she can't help but ask.
"He is a mad scientist, he will pay anything as long as he can get what he wants"
"Do you have something that he needs, sensei?" She always feels Kaoru is a very strange person.
he is strong, but not many people know about his strength.
he is also smart, but sometimes he acts like he has a screw loose in his head, for example, today when he burned the forest just to scare that person.
his Just also very creative and destructive, but he always uses some strange chant to use it instead of a normal hand seal.
and this time he said that he has something that may be needed by a person like Orochimaru.
"Don't think too hard Ino, just believe in me" Kaoru wants to assure Ino that everything is fine.
he also believes that compared to someone like Danzo or Hiruzen, Orochimaru actually is like a docile animal.
what he wants is just immortality, but Danzo, Hiruzen, and those old fools want domination under their name.
and the ending for that kind of person is always death, Of course, if you're a son of heaven or the chosen one your path will be hard but not impossible, maybe except for that certain fake god with a suspicious book.
after waiting for a few minutes the other Jounin arrived together with some Anbu and the second exam proctor, Mitarashi Anko.
looking at someone she knew Anko approached him.
"Did you meet him?"
"Yes, I also burned his tail" Kaoru of course knew who is the one that Anko mentioned.
"HAHAHA, I wish I could see it myself" Anko's relationship with Orochimaru is a bit complicated, he is her teacher, but he is also the reason her life turns worse.
"Can you follow me, Those annoying fellows want to hear the chronology"
"Okay!" Kaoru thinks it's not fair for a beauty like Anko to turn into a pig in Boruto, so he thinks about making a training menu or maybe asking Chifuyu to make it for her.
-----
After making a report about Orochimaru and bringing Karin to Shirou, Kaoru back to the surveillance room.
inside the exam site, Team 10 and Team 7 got a free pass since they already collected both scrolls of heaven and earth.
but the main reason is that just by surviving after fighting against Orochimaru is already enough to not let them stay at Genin.
hearing that statement all of them feel happy except one person, Haruno Sakura, She feels useless because she can't do anything in that battle, even Ino could fight far better than her.
because of this incident Sakura who was just a stupid simp before, now found her resolution to move forward and not to be a burden for her teammates.
She also found the right person to ask, since she knew asking Kakashi was useless, he was one of the laziest people that she knew even more than Naruto.
-------
After arriving at the middle tower they are allowed to open the scrolls and what they receive is similar to the canon, some sermon from their Iruka.
what they didn't expect is that the team Guy and the team from Suna are already there.
this time what they need to do is rest and Sasuke who got the cursed mark from Orochimaru receives special treatment from Kakashi.
but he seemed to haven't noticed or maybe didn't even care about Naruto with a blocked chakra pathway.
that's why Kaoru never likes Kakashi, he is like an ungrateful bastard, what is so hard to recognize Naruto's identity especially since he is the former Captain of the Anbu team.
yellow spiky hair, a Uzumaki, and also a Jinchuriki, As long as you connect those lines you will know that Naruto is Minato and Kushina's son.
"Sorry Naruto, I'm not good at sealing Jutsu, I will try to find someone to break that seal" Kaoru really wanted to destroy that seal but he didn't know how, he also didn't want to wait for that pervert sage.
'It seems like I have to buy it from that snake' Kaoru believed that even if he asked for more Orochimaru would give it to him as long as he told him that shortcut.
"Don't worry Kaoru-nii, I will become Hokage someday and this small thing will not stop me, dattebayo!"
Naruto is a bit stupid but his willpower is something that Kaoru has to acknowledge, if Naruto is born in the One Piece world then he surely will awaken Haoshoku Haki since childhood and become one of those monsters.
"The third exam will be a duel and as long as you win I promise to give you a little surprise, Do your best" Kaoru gave Naruto some encouragement and patted his head.
"I promise I will, ttebayo!"
and the qualification for the third exam is held after every examinee who passed the second exam arrived.
