Reborn as Danzō’s Grandson, Must I Offend the Entire Ninja World?

Bang!

The wooden door exploded, sending debris flying in all directions.

Inside the room, a group of thugs who had been drinking and playing cards froze in shock, their eyes snapping toward the entrance.

As the dust settled, a small figure stepped inside, carrying a sword nearly as tall as himself.

"Hello," Yami greeted them with a childlike smile, his tone almost playful.

"I'm here to send you off."

"But before you die, can you at least tell me your name?"

"Consider it a free hospice service from me."

The room fell silent for a brief moment.

Then—

Laughter erupted.

A burly man stepped forward, slapping his knee as he laughed so hard he nearly fell over.

"Hah! Where did this ninja brat crawl out from?" he sneered. "He actually thinks he can kill someone? I'm standing right here, kid, go ahead, try stabbing me!"

Another thug chuckled, waving a hand dismissively.

"Little punk, have you even seen blood before? Go home!"

Had an adult ninja barged in, they wouldn't have dared to be so arrogant.

But a six or seven-year-old? Even if he was a ninja, what could he possibly do?

Yami simply repeated his question.

"What's your name?"

The burly man smirked, puffing out his chest.

"Hah! The name's Uesugi Taro, you little—"

Slice!

A single downward slash.

A thin red line appeared on the man's forehead, running down the bridge of his nose.

Then—

His entire body split cleanly in half.

He collapsed to the ground with a wet thud, his organs spilling out onto the floor.

"Tsk."

Yami instinctively frowned.

The mental impact of his first kill wasn't as bad as he had imagined.

But the physical reaction, the stench of blood and intestines, made his stomach churn.

For a while, he probably wouldn't be able to stomach eating meat.

At that moment, the system notification chimed.

[Host has established a "Life and Death Bond" with Uesugi Taro.]

[Stage 3 reward issued: +0.1 Standard Genin Chakra, minor physical enhancement.]

Perfect.

His guess had been correct.

The Bond System required intense emotional triggers to activate.

And what stronger emotion existed than the moment of death?

"Life and Death Bond"… fitting.

I live, he dies. It's a fair trade.

For a brief moment, the room was stunned into silence.

Then—

The remaining thugs finally snapped out of their shock, grabbing their weapons and charging at him with enraged shouts.

Though civilians were generally afraid of ninjas, these men were trained fighters.

They weren't as weak as ordinary villagers, and two of them were even Chūnin-level rogue ninja.

They assumed Uesugi Taro had died because of a sneak attack, not because this child was actually strong.

They had no idea what they were up against.

Yami didn't even bother dodging.

He met them head-on.

Clang!

A sword swung at him.

It shattered upon impact.

In the next instant, Yami's blade sliced through the attacker's legs, sending him collapsing to the floor, screaming.

Outside, perched on a rooftop, Owl silently listened to the dying screams coming from inside the house.

His expression remained unchanged.

The only thing that mildly intrigued him was Yami's peculiar habit.

It seemed that, before killing someone, Yami insisted on knowing their name.

And if they refused, he would torture them instead of granting a quick death.

A rather… unique quirk.

---

Three minutes later, Shimura Yami stepped out of the house.

The screams had completely stopped.

"Lord Yami, are you alright?" Owl asked.

"It wasn't as bad as I thought," Yami replied, shaking his head slightly.

"But I'll need more practice to fully adapt."

Owl gave a small nod.

"Understood. Danzō-sama has prepared ample resources for your training. If you don't need rest, we can proceed to the next target immediately."

"Let's go."

Yami exhaled deeply, sheathing his sword.

The sooner he finished this training, the sooner he could return home—and see his cute, soft loli again.

Although he wasn't sleeping outdoors, nothing compared to the comfort of his own bed.

"Please wait a moment," Owl said. "We still need to recover assets."

The Root subordinates sprang into action.

The Root wasn't just good at killing, they were experts at looting as well.

Within ten minutes, they had gathered every valuable item in the mansion—cash, gold, silver, jewelry, and property deeds.

Shimura Yami flipped through a pile of documents and banknotes, nodding in appreciation.

"Not bad… this guy was loaded."

The village crime lord had 20 million ryo in cash and that wasn't even counting his land holdings.

Then—

A particular note caught his attention.

Yami stopped flipping and picked it up.

[IOU: I, Princess Tsunade, borrowed 8 million ryo due to a shortage of gambling funds. I promise to repay it before January 1st, Year 54 of the Konoha Calendar. If repayment is overdue, monthly interest will increase by 1%.]

A strange smile crept across his face.

Tsunade's IOU…

Folding the IOU neatly, Yami tucked it away.

Then, sealing 3 million ryo into a storage scroll, he turned to Owl.

"The rest is yours. Do what you want with it."

Owl remained silent.

Although he was technically the team leader, Yami's authority in Root was second only to Danzō.

He had no right to oppose Yami's decisions, only to report them honestly.

---

One Month Later

For the next several weeks, Yami was either killing—or on his way to kill.

His targets ranged from:

Common thugs and ruffians

Large bandit gangs

Even corrupt noblemen in the Land of Fire

As his Kusanagi Blade was soaked in blood, his growth accelerated.

Not just in power but in mentality.

He no longer hesitated to kill.

Regardless of the enemy's age or status, he had learned to strike without mercy.

Finally.

After eliminating a corrupt real estate tycoon who had swindled Danzō's resources, Owl called off the mission.

"Lord Yami, your training is complete."

"From here, you will proceed to poison and trap training, under the Captain of the First Squad."

"Is it over?"

Yami's smile was bright and innocent, almost unbelievable, given how many lives he had taken in just one month.

"Speaking of which, Owl…"

Yami slowly wiped his palm with a handkerchief.

"We've known each other for a while now… but I still don't know your real name."

Owl's cold voice responded.

"Root operatives have no need for names, only codenames."

Yami smirked.

"I'm ordering you as your superior, tell me."

A long silence.

Then—

Reluctantly, Owl spoke.

"Uzuki Shinji."
