Chapter 8

Konoha, Ninja Academy

Today, Rimuru has taken the duty of picking up tsunade and bringing her home. He stood at the gates of the academy with the other parents or guardians and occasionally heard some of their gossips.

"Have you heard that war is about to start?"

"Yeah… but isn't Lord hokage protecting Konoha right now? Lord Hokage is the younger brother of the first hokage who suppressed a tailed beast, you know? he isn't weak."

"I know he isn't weak but… isn't the first hokage the deterrence of the village? If he's… dead then wouldn't the deterrence disappear?"

When he heard the somewhat interesting remarks from the civilians, his eyebrow was raised a bit.

'isn't the villagers supposed to be ignorant and stupid? How did they know these kinds of stuff?'

Rimuru rubbed his chin in thought.

From what he knew, the villagers in the original timeline beat child naruto who looked almost like a carbon copy of the fourth hokage with only the addition of whiskers.

Question: Why do they know the death of the first hokage which should be a secret, an S-class secret right now?

If their IQ or gossiping skills are so high then why wouldn't they know that child naruto is the child of Minato Namikaze?

Answer: The villagers are blinded by their hatred. Violent emotions like hatred leads to distortion of the rational mind leading to false conclusions that originate from flimsy evidence brought by their outside observation and untrustworthy rumors with no further investigation.

Though the third hokage may or may not be fanning the flames in this rumor but that is just speculation with no prove or evidence whatsoever.

As rimuru was having a random thought, a small figure run up and hugged him. a fragrant smell of flowers appeared and when he looked down, he found it was tsunade.

"Brother Rimuru, I'm here!"

Her voice attracted the other parents and guardians, who were gossiping, and they looked at the two in surprise.

"Is that Rimuru-sama?"

"Yes, I think so too."

"I heard he was engaging in some… disgusting relationships with his students."

"That's probably true, man. You could see that princess tsunade has fallen in his clutches."

Their muttering voice could be heard by rimuru who is a bit embarrassed at their statement.

'Hey! The last one is completely false and slanders my good and kind nature.'

Rimuru held tsunade's hand and quickly walked away from the unkind rumors gossiped by the civilians.

He doesn't want to continue hearing more slanderous words from the civilians.

It's just looking for abuse.

"Ne Ne~ Brother, where are we going? Gambling house? The bar? Or a love hotel?"

Rimuru suddenly stopped walking when he heard the last part.

The gambling house is fine because he often goes with her to the gambling house because she likes gambling.

The bar is also fine because he likes drinking and when he's drunk, tsunade always picks him up.

Where did she get the idea of going to a love hotel? I mean where did she get the term of love hotel?

Wait… wait, wait, wait. Did tsunade began reading ero-manga because that still exist though in its infancy.

'f*ck' was all rimuru thought when he began thinking about tsunade's words.

A big blush appeared on tsunade's face when she said her words, though rimuru was still in a daze.

"Brother~ Let's go! You said you were going to teach me something!"

Tsunade changed the topic as she suddenly remembered that rimuru is going to teach her some important things.

Returning to his calm expression, rimuru nodded at tsunade's words as the two quickly head to the nearby training ground in the academy.

In a few minutes, they arrived at the training grounds where a kid just 1 year younger tsunade was training.

He has thick eyebrows, a bowl haircut, and wore a green jumpsuit.

When the kid saw the two coming in the training ground, he walked up to them, showed a thumbs up and a big smile, and said: "Hello, I am Might Duy. Nice to meet you! Do you want to join me in my training of Youth?"

"No thanks, Duy-san. I'm here to teach my student something. By the way, I'm rimuru and my student here is tsunade." Said rimuru with a smile.

Tsunade nodded at rimuru's words while Duy is a bit disappointed but quickly showed a bright smile and left to continue on his own training.

Rimuru then turned towards tsunade and began explaining to her what he's going to teach.

"Tsunade. Today I'm going to teach a technique that perfectly complements your chakra enhancement jutsu."

Tsunade curiously looked at rimuru when she heard his words.

The chakra enhancement jutsu enhances her physical power which allows her to break the ground and crack a boulder.

If there is enough chakra then breaking a mountain isn't impossible.

What technique could complement this behemoth of a jutsu?

"This isn't a chakra technique, tsunade. As for the name of this technique, it is called Haki." Rimuru said. "There are 3 different types of Haki in this world. Mainly, Observation Haki and Armament Haki. The third kind is a very rare Haki that only those with enough qualifications as a king can have."

He then continued.

"What I'm going to be teaching you is armament Haki which would greatly increase your power and defense."

After finishing the explanation, tsunade still looks confused as the explanation only gave her meager information and doesn't explain the principles of Haki at all.

Rimuru sighed at this but said in a very simplified manner.

"You just need to master yin chakra and wrap it around your hand or any parts of your body to greatly enhance it."

A look of enlightenment appeared on tsunade's face.

When Madara explained the principles of Susanoo to tsunade, he said that Susanoo in a simplified term is an extreme use of Yin chakra with the addition of a tiny amount of yang chakra to support its form.

Although yang chakra isn't needed to form the first four stages of his Susanoo, the last stage would need it because the scale is too big for the yin chakra to handle.

Theoretically, you could use yin chakra to wrap at any points of your body part and it'll be greatly strengthened.

The best part of it all is that it doesn't need to much yin chakra and could last hours for an average jonin.

The only problem is that controlling yin or yang chakra isn't an easy task.

Although it is possible to use yin or yang chakra as you could see from low-level illusions and medical jutsus, high-level yin or yang chakra is needed for the principle of armament Haki is needed.

Tsunade felt the feasibility of this armament Haki and looked at rimuru with admiration.

"Wow! Brother, I didn't know you would invent new jutsus. Not to mention your principle of using high-level yin chakra to greatly enhance the physique!"

When seeing the admiration of tsunade and hearing her statement, rimuru felt a bit embarrassed. He scratched his head and showed a rather stiff smile.

The admiration of tsunade came from the novel use of yin chakra at a very high-level which no one in the ninja world could think of.

But…

Rimuru just took the principle of armament Haki in the one piece world and made his out own interpretation of the armament Haki equivalent of this world.

Basically it is copying from other world's principle.

Telling a white lie to his younger sister makes him feel guilty.

Suppressing his inner guilt, he said to her: "Then let's start. I'll teach you a method to quickly transform attributeless chakra to yin chakra, but you only need to convert a bit of your chakra, not half or all of it."

"Yes brother rimuru!"

Tsunade readily agreed to rimuru's words.

Rimuru walked closer to tsunade and tapped her forehead, transferring chakra that contains the information directly to her brain.

An easy way to transfer techniques without having it leaked.

A trace of surprise flashed in her eyes when seeing another unique technique of rimuru but quickly went to the information in her brain.

"Ah~ So it's like this…"

Feeling that she understood the technique, she began converting 1% of her chakra to yin chakra and followed the method in her mind.

Rimuru looked quietly at the peaceful tsunade.

"Cute."

His nimble hands moved towards tsunade's cheeks with slight baby fats.

He began squeezing and stretching it a bit, feeling the softness and fluffiness of it.

Tsunade's eyebrow twitched a bit, feeling the unpleasantness of her cheeks being squeezed and pulled.

Just as she was about to finish following the method, the unpleasantness disappeared.

When she opened her eyes, she saw rimuru sat on the grass near her, reading a book about algebra.

"Hm, I was sure it was brother rimuru who was bullying me…" she muttered.

She thought she found the culprit who pulled and squeezed her cheeks. Now her cheeks had turned red, so she knows it wasn't an illusion.
