it's a sunny day and Team 10 already started their training earlier.
"That's good Shikamaru, remember hand seal is not a requirement to use a Jutsu."
Kaoru knows that hand seal is just a trick for those ninjas to focus on using their Jutsu since some people could use a Jutsu with one hand or maybe skip every seal and use the final hand seal.
and he believes that kekkei genkai is just another branch of Ninjutsu, for example, Hiruzen uses the combination of water and earth chakra to create a mud element but Yamato uses the same chakra to create a wood element.
the only difference is Hashirama's cells but even in his world cell transplant is a dangerous surgery especially when the recipient's cells reject the donor's.
that means the next problem is from Hashirama himself, what is the difference between his water and earth chakra and Hiruzen's.
Kaoru believes the reason is Nature energy, Hashirama could use Senjutsu but his brother and his descendants cant use it, the reason is not that Hashirama didn't teach them, but because he is a natural genius that awaken the Senjutsu without learning from anyone and that's why he thinks that Senjutsu is just his inherent talent.
he doesn't have any proof especially since he can't use Senjutsu but he still believes that is the reason.
and kekkei genkai is just a combination of two or more elements plus Senjutsu chakra, of course except for the physical kekkei genkai like byakugan or Sharingan, but he still believes there is a non-genetical factor that creates a Sharingan or any other physical kekkei genkai.
"Okay, it's enough for today's training"
hearing their sensei's words team 10 stopped their training and walked toward Kaoru.
"Today we will start to take a mission, and I will let you guys choose the mission but remember that as a genin you are only allowed to take a D or C rank so I hope you will not become an idiot who asked for an interesting mission"
"hey, Ino why is it that I imagine Naruto's or Kiba's face when sensei talking about an idiot?" Shikamaru whispered to Ino.
"yes I also imagine the same thing"
"Now just go to mission hall, I already told them that you guys will be the ones who take the mission!"
"yes, sensei"
with Kaoru's command, the three of them ran to the mission hall excitedly because they could choose their mission, and since this is the first mission they also want to take a mission that they will always remember later.
-------
looking at the mission details, Kaoru got stunned and can't give any comment.
among so many choices, what they take is the mission to find Madam Shinji's cat, Tora.
in the original story, this cat is like a menace to Genins since she has good hiding skills and is capable to escape easily from a team of Genins.
also don't forget in the original she is even could flee from that emo boy's eyes, she also has higher stamina than that orange Durian head.
"Since the mission is in Konoha, that means you guys should do it yourself, I will not help you also think this is as a lesson, after you complete the mission I will ask what you learn from the mission today"
team 10 is different from the other team, they already have basic teamwork, and this team also has a good balance position.
this mission is also only inside Konoha, in this early stage there are only Danzo and his roots but they are not that idiot to attack a successor of Nara, Akimichi, and Yamanaka clan inside of Konoha.
"Since you guys are ready, the first mission of team 10 is now, BEGIN!"
with Kaoru's command, the three of them disappear and started to search for their target.
--------
in the evening, Kaoru can't hold his laugh looking at his students' miserable state
"HAHAHAHA, you guys look like a loser that lost all his hope and money in gambling"
their face turns sour because the mission that they thought will be easy money turn out to be a trap instead.
------
in a certain casino, there sat a beautiful blonde woman with tremendous 106 assets that focused on a game, the only strange thing is that no matter how much she play she never win even once.
*achoo
"Tsunade-sama let's stop for today, see you catch a cold and we lost too much already" a black-haired woman beside her persuades Tsunade the blonde woman to stop gambling since they already lose several million Ryo.
hearing her student's words, Tsunade's face turns ugly.
she knows that fact but for her gambling is like a sword for those samurai.
"fine, this is the last!" she said, but the one who know her will understand whether she will stop or not.
------
the three of them feel wronged when they look at how their sensei laugh to his heart's content.
"Sensei why didn't you say anything to us about this mission"
"yup, that cat is very strong and I'm hungry now so I demand a meal at Yakiniku Q"
both Ino and Chouji told Kaoru their complaint but there is only one person that still silent since the beginning.
"Okay, okay I will treat you guys later, but Shikamaru what do you think about your mission today"
Shikamaru is a smart kid so he knows the meaning of Kaoru's question.
"yes, we are too excited about the mission to the point that we didn't search for information about it, and we also underestimated this mission, since this is just a D-rank mission and the payment is good we are thinking this will be easy money. I also overlook your expression when we showed the mission scroll to you, looking at your expression earlier I should have a suspicion, but I chose to ignore it instead"
*clap clap clap
"That's right what you did today is the most basic mistake that every ninja could do, but has the greatest consequence, you didn't try to collect information about the mission, even if they have checked it there is still a chance that some strange or dangerous mission included in the lower rank mission"
"And you also underestimated the mission, if you're unlucky maybe you will get an A-rank mission you undertake a C-rank mission"
"Also when you meet the client or maybe someone related to the mission you should always stay vigilant no matter how easy it looks like"
"the moment you make those mistakes, not to mention yourself, maybe your friend or family could be implicated by it, understood!?"
Kaoru likes these three kids that's why he will give his best for them and he will also make sure they could survive in this strange world since he remembers that in Boruto their enemies will be overpowered aliens.
"Yes, sensei!"
the three of them answer simultaneously, they understand this is their first mission and the mission is actually not that difficult if they do it seriously that's also the reason Kaoru only gave them a small sermon.
