"I never thought that one day I would transmigrate to Konoha, and... damn it, I ended up being a trainee teacher."
"Fuck!"
Kanda Kyōichi sat in the office questioning his life choices.
Just the day before, he had been worrying about elementary school kids not liking male teachers.
Who would have thought that the next day he wouldn't need to worry about unemployment or parent complaints anymore, but now...
Looking at the noisy children outside, he couldn't muster any excitement.
The shinobi world was too dangerous!
While Konoha was relatively safe, disasters still struck frequently over the years.
Just recently, the Battle of Kikyō Pass had ended.
Kyōichi had returned to the village injured, and after his wounds initially healed, he was assigned to teach at the ninja academy.
"Ah, it's a pity the Senju clan has declined. Otherwise, I could have relied on them for an easy life..."
Kyoichi sighed.
The Kanda family has Senju bloodline.
The Senju clan was once glorious.
However.
Starting from the First Hokage, the Senju clan began to fragment and integrate into Konoha.
By the time of the Second Hokage, only a few direct descendants remained, and now...
Basically, only Tsunade could truly be called a Senju.
Yet.
Even Tsunade didn't use "Senju" as her surname, so Kanda Kyōichi couldn't benefit from the Senju clan's influence.
He estimated that his Senju bloodline wasn't very strong either—
At least not stronger than Tsunade, who was the first Hokage's granddaughter .
The Sage Mode was out of the question.
As for talent...
At fifteen or sixteen, he was still only a Chunin, and that seemed to be his limit.
Kyōichi was very worried.
At this rate, even living to old age was questionable, considering the future disasters Konoha would face—the Third Great Ninja War, the Nine-Tails' Night, the Konoha Crush Plan, and so on.
A mere Chunin facing those enemies would be like an ant trying to shake a tree.
Even the aftershocks could kill him.
"Maybe I should try to get some Hashirama cells later, then there might be a chance to master Wood Release," Kyōichi thought to himself.
The shinobi world was too dangerous.
Not getting stronger was just waiting to die.
Just as he was pondering this, the bell rang outside.
Class was over.
"I think I have the next class."
Kyōichi mainly taught "Ninjutsu."
He didn't understand why he was teaching this subject.
After asking around, it seemed the previous sensei had died on the frontlines, and they had grabbed him as a temporary replacement for the vacant position.
So, Kyōichi was in an intern position.
Well, might as well go teach.
After all, the academy's ninjutsu classes weren't difficult - just the three basic techniques. The memories in his head were enough to fool the kids.
Kyōichi thought to himself.
Just as he stood up, a strange voice suddenly rang out.
At first, he couldn't hear it clearly.
But.
he understood after the voice repeated itself.
[Mentor System activating...]
[Activation successful!]
[Teaching students wholeheartedly will earn rewards, becoming a life mentor will earn additional rewards.]
[Beginner's package available, would you like to claim it?]
Host:
Mentor System?
Beginner's package?
What is this...
Some kind of onboarding gift?
Kyoichi was stunned for a moment, then thought to himself: "Claim it!"
"Your Three Basic Techniques proficiency has been raised to the maximum."
"You have received a reward: Blood Purification."
"Your bloodline has been purified, upgraded to Senju bloodline, your constitution has been greatly enhanced."
"Your Earth Release and Water Release effects have been enhanced."
In the hallway, Kyōichi's mind was first filled with many applications and knowledge about the Three Basic Techniques, then he felt his blood boiling.
He could tell his body temperature was rising.
Was this the purification effect?
He was confused at first, but then came a wave of wild joy.
Senju bloodline!
Just looking at the immediate effects, the improvements in constitution, Earth Release, and Water Release were obvious.
Moreover.
A stronger constitution meant more chakra as well.
The future benefits would be even greater.
Identity, compatibility with Hashirama cells, and so on - all could be dreamed of.
Furthermore, with this "Mentor System," if the beginner's package was already this powerful, who knows if there might be chances to obtain the Sage Body or even the Rinnegan in the future?
With this system, he actually had a chance of survival in the ninja world.
Kyōichi couldn't help but feel excited.
"I wonder how this Mentor System works..."
He pondered to himself.
From the system prompts, rewards could be earned by teaching students wholeheartedly, but it also mentioned getting more rewards by becoming a life mentor.
However.
What exactly was a life mentor?
After much thought, Kyōichi decided not to overthink it and head to the classroom first.
He wanted to see who his students were.
After the blood purification, he quickly noticed changes in his constitution.
Just walking felt much faster!
At the classroom door, he saw a familiar face.
Uchiha Obito.
This guy...
"Are you Uchiha Obito?"
"Yes, sensei."
Seeing Kyōichi, Obito seemed nervous and fidgeted at the doorway.
"Go take your seat."
No need to guess.
He must be late again.
Inside, he saw several familiar faces.
Rin, Yuhi Kurenai, Asuma.
Additionally.
Shisui, Anko, and Hayate were also in the class.
During wartime, manpower was scarce.
Many teachers had gone to the frontlines, so students of similar ages were combined into one class - this was a temporary policy, something that couldn't be helped—
Including Kyōichi's temporary recruitment.
"Hello everyone, I'm Kanda Kyōichi, and I'll be your ninjutsu instructor from now on."
"Sensei, sensei, I heard you just came back from the battlefield? Can you teach us more practical ninjutsu!"
As soon as Kyōichi entered, Obito shouted out.
This guy really wasn't shy at all.
A pure social butterfly - they'd only just met, but he was acting like they'd known each other for ages.
Kyōichi gave him a speechless look.
However.
Besides him, Yuhi Kurenai, Rin, and others were also curious about their teacher who had returned from the battlefield, harboring some expectations.
They all wanted to graduate early.
Therefore, battlefield experience and new jutsu were things they aspired to learn.
However.
Among the jutsu Kyoichi had mastered, besides the Three Basic Techniques, he only knew Shadow Clone, Body Flicker, Water Wave, and Water Formation Wall. He couldn't possibly teach these to them, and...
He gave a wry smile, looked around, and said: "Do all of you think your Three Basic Techniques are already completely qualified, and you don't need any more practice?"
No one answered, but all the children's expressions showed they agreed internally.
"Alright, then for today's first lesson, I'll teach you the Three Basic Techniques. If you can meet my standards, what's wrong with teaching you a new jutsu?"
Kyōichi smiled.
With his maxed-out Three Basic Techniques, teaching them would be more than manageable.
These kids wanted to walk before they could crawl.
"Let's go to the training ground."
"Alright!"
At the training ground.
Kyōichi's eyes swept across everyone.
There were quite a few prodigies here, but in terms of overall ability, Obito could at least rank in the top five—he just didn't have the Sharingan yet.
Besides him.
There was probably Shisui.
"Obito, Shisui, come forward."
"Yes!"
Obito came to the center with great enthusiasm.
Shisui followed.
Two against one?
"Both of you, attack me with everything you've got!"
