Chapter 42: Chapter 42: Kamado Tanjiro Template

"I didn’t expect to still lose to you."

Nawaki sighed.

A year ago, during their first spar, Natsuki’s kenjutsu had shocked him.

To avoid being overtaken, he had spent the past year diligently mastering Chakra Enhanced Strength and Water Release.

He had thought he could maintain the gap between them—but it had only lasted a year before he was defeated.

For someone who had been called a genius since childhood, the realization was disorienting.

"I had the advantage of self-created techniques."

Natsuki sheathed his wooden sword. "That’s not a fair comparison."

"Self-created techniques are still a manifestation of strength."

Nawaki shook his head.

Losing to Natsuki stirred complicated feelings—but a loss was a loss. He wouldn’t make excuses.

"Both of you performed very well."

Orochimaru interrupted their conversation.

The current Nawaki had mastered Chakra Enhanced Strength and multiple Water Release ninjutsu. His strength was comparable to an elite Chunin.

And he was only eleven years old. His future was limitless.

Natsuki needed no further explanation.

Creating kenjutsu, ninjutsu, and secret techniques at age eight—given enough time, becoming the second Senju Tobirama wouldn’t be a problem.

Most importantly, both of them were his students.

For a moment, Orochimaru felt deeply satisfied.

"We’ll fight again next time."

Nawaki quickly recovered his spirits and grinned. "I already understand your shadow techniques now."

"Maybe I’ll have a new one by then."

Natsuki blinked.

"...?"

Nawaki’s mouth twitched.

Why does creating secret techniques sound so casual when you say it?

[You have awakened the Kamado Tanjiro Template.]

Who?

Natsuki’s heart jolted—then excitement surged.

Kamado Tanjiro was the male protagonist of Demon Slayer: Kimetsu no Yaiba.

Why had he awakened this template because of Nawaki?

Natsuki quickly examined the details.

[Name: Kamado Tanjiro]

[Era: Pre-Natagumo Mountain]

[World: Demon Slayer: Kimetsu no Yaiba]

[Rank: B-Rank]

[Ability 1: Water Breathing — Unlocked]

[Effect: A fusion of the original breathing style and Water Release. Enhances physical abilities while also amplifying the power of Water Release techniques.]

[Ability 2: Water Breathing — First, Second, and Third Forms — Locked]

[Effect: The first three forms of Water Breathing.]

[Unlock Condition: Achieve beginner-level Water Release chakra nature transformation.]

[Ability 3: Water Breathing — Fourth, Fifth, and Sixth Forms — Locked]

[Effect: The middle three forms of Water Breathing.]

[Unlock Condition: Defeat three Chunin or Tokubetsu Jonin who excel in Water Release or kenjutsu.]

[Ability 4: Water Breathing — Seventh, Eighth, and Ninth Forms — Locked]

[Effect: The final three forms of Water Breathing.]

[Unlock Condition: Achieve proficient-level Water Release chakra nature transformation.]

[Ability 5: Water Breathing — Tenth Form: Constant Flux — Locked]

[Effect: Like a coiled dragon, launch a continuous series of rotating slashes.]

[Unlock Condition: Completely master Water Breathing and unlock Total Concentration: Constant.]

After reading, Natsuki nodded to himself.

As expected.

Kamado Tanjiro knew both Water Breathing and Sun Breathing—but the template only provided Water Breathing.

This was undoubtedly related to Nawaki’s Water Release.

Natsuki stood in place, digesting the information flooding his mind.

The essence of the breathing styles in Demon Slayer was strengthening cardiopulmonary function—absorbing massive amounts of oxygen in short bursts to enhance physical abilities.

When combined with various kenjutsu, it produced styles like Water, Thunder, Flame, Stone, and Wind.

Although they appeared to have elemental properties, they were primarily physical attacks supplemented by sword aura.

But after the system’s modification, Water Breathing had become true Water Breathing—fusing Water Release with the breathing style.

It could enhance physical abilities and amplify Water Release power.

This meant Water Release techniques in the ninja world could benefit from Water Breathing’s enhancement.

Because of this, after awakening the template, Natsuki had automatically acquired the Water affinity.

Combined with his previous Earth and Wind affinities, he now possessed three chakra natures.

An unexpected but welcome surprise.

And with the Water affinity, achieving Ability 2’s unlock condition would be much easier.

It required beginner-level Water Release chakra nature transformation.

Chakra transformation was divided into two categories: shape transformation and nature transformation.

Shape transformation referred to the form chakra or ninjutsu took.

The Rasengan, for example, was known as the pinnacle of shape transformation because its form wasn’t fixed—it was an irregular rotation.

Nature transformation meant converting inherently neutral chakra into elemental chakra—Earth Release, Lightning Release, Wind Release, and so on.

Natsuki already possessed the Water affinity.

Beginner-level transformation required converting his chakra into Water Release anytime, anywhere.

Proficient and mastery levels had higher requirements—molding Water Release chakra into any shape imaginable.

That was also the unlock condition for Ability 4.

Among the four locked abilities, Natsuki felt Abilities 2 and 3 had the simplest conditions.

They could be completed given enough time.

Although defeating three Tokubetsu Jonin who excelled in Water Release or kenjutsu would be troublesome.

The most difficult to unlock was undoubtedly Ability 5.

It required achieving Total Concentration: Constant for Water Breathing.

Simply put—maintaining Water Breathing active 24 hours a day, thereby improving baseline stamina.

Difficult as it was, mastering Total Concentration: Constant meant training his body around the clock.

Both taijutsu and kenjutsu would receive corresponding enhancements.

In combat, that was a massive advantage.

"Nawaki-senpai, can you teach me Water Release chakra nature transformation?"

Natsuki composed himself and asked.

"Why do you suddenly want to learn Water Release?"

Nawaki blinked, caught off guard.

"Creating two shadow techniques—which are Yin Release ninjutsu—is already my limit."

Natsuki spoke half-truthfully. "My next goal is creating Water Release ninjutsu. You know the Second Hokage is my idol."

Nawaki opened his mouth—then closed it, speechless.

Although learning Water Release was simpler than Yin Release, creating Water Release was an entirely different matter.

Moreover, given Natsuki’s age, learning Water Release at all was extremely difficult.

Normally, proficiency in two chakra natures qualified someone to become a Jonin.

"Then can I learn whatever Water Release you create?"

Nawaki recovered and asked curiously.

"If there’s something suitable for you, I’ll teach you."

Natsuki replied.

How should I put it?

Nawaki definitely couldn’t learn the ten forms of Water Breathing—he didn’t know kenjutsu.

But he might be able to learn Water Breathing itself. 𝒻𝑟𝘦𝘦𝘸ℯ𝒷𝑛𝘰𝓋ℯ𝘭.𝘤𝘰𝘮

Natsuki could use this opportunity to verify whether the abilities he acquired could be taught to others.

"Then I’ll teach you the Water Release I learn too."

Nawaki said.

He had always been fair.

Natsuki nodded.

Senju Tobirama’s Water Release was genuinely excellent.

With Water Breathing amplifying his Water Release power, learning a few additional techniques wouldn’t hurt.
