Mother and little sister

The Uchiha Clan Compound.

"Boss, I'm hungry."

The black cat lay on his shoulder, affectionately rubbing his furry head against his owner's neck.

Uchiha Jin: "..."

It hadn't even been an hour since they'd finished those skewers of candied hawthorn.

Yet the fat cat was hungry again.

"Mother should have dinner ready."

Although he was a transmigrator, he hadn't lost both his parents.

Only his father had died.

And he had a little sister five years younger than him.

"Yay!"

The black cat's eyes lit up, his tail swishing nonstop behind him.

"Let's hurry home."

"Big brother, you're back!"

As soon as Uchiha Jin returned home, a little girl rushed up excitedly.

"Quick, give me Little Blackie to play with."

"Boss, no!"

The black cat tried to run when he saw the little girl, but Jin picked him up by the scruff and handed him to his sister.

"Little Blackie, why are you running?"

The black cat was mercilessly squished in the girl's arms and closed his eyes, having lost all will to live.

"Say, how come you've gotten fatter again?"

"Little mistress, I'm not fat. I'm clearly muscular!"

Hearing someone call him fat, the black cat immediately protested, raising his plump, furry paws in the air to show them off.

His adorably goofy appearance made the little girl giggle.

"Izumi, stop picking on him."

Uchiha Jin looked at his sister tenderly, reaching out to ruffle her hair affectionately.

"Big brother, stop touching my head all the time. Mom says I won't grow tall that way."

Uchiha Izumi pouted in displeasure, but didn't actually swat her brother's hand away.

Although she protested aloud, she actually enjoyed having her brother pat her head.

"Did anything interesting happen at school today?"

Today was the day Uchiha Jin joined the Konoha Military Police Force, as well as the day Uchiha Izumi was old enough to start school.

"Big brother, Itachi and I were put in the same class."

At his sister's words, Jin's smile stiffened for a moment.

In the original story, Izumi and Itachi could be considered childhood sweethearts, and she had died at Obito Uchiha's hands on the night of the massacre.

But ultimately, Itachi had been the one to set the massacre in motion first.

Poor Izumi had believed right up until her death that Itachi would come to save her, never knowing that the Uchiha weasel was one of the perpetrators.

"Big brother?"

Uchiha Izumi noticed his expression and asked in confusion.

"What's wrong?"

"Nothing. That kid Itachi isn't a good person. Don't spend much time with him at school."

Uchiha Jin spoke with a serious expression.

"Okay."

Although Izumi didn't understand why her brother would say that, she couldn't go wrong listening to him.

Besides, she wasn't actually all that close to Itachi.

She had only mentioned it to her brother because Itachi was the clan head's son.

"Time to eat."

Uchiha Kazuna came out of the kitchen carrying a dish, looking tenderly at the siblings in the courtyard.

"Go wash your hands."

"Coming, Mom."

The two siblings and the cat washed their hands and came to the dining table.

"Here's your cat food."

Under the black cat's pitiful gaze, Uchiha Kazuna filled the bowl in front of him halfway with cat food.

"Mom, I'm so hungry..."

"No. You're getting fatter and fatter. For the sake of your health, you need to start watching what you eat."

The black cat looked aggrievedly at Uchiha Jin. "Boss, this is way too little, meow."

He normally ate a whole big bowl, but now his portion had been cut in half.

Wouldn't he starve to death?!

"Listen to Mom."

Uchiha Jin also thought it was time Little Blackie lost weight. He was clearly a black cat, yet he was as fat as a pig.

Who knew how he managed to eat so much food?

The black cat: "..."

The thought of his food being halved from now on was unbearably miserable.

The sky had fallen.

He really didn't understand how he was fat. He was clearly muscular!

Didn't they understand muscle under fat?

Watching the black cat hang his head dejectedly, Uchiha Kazuna smiled and spoke gently.

"If you dare sneak food, I'll take you to get neutered."

At those words, the black cat's eyes instantly cleared.

He was still an innocent little virgin kitty who had never even held a female cat's paw.

If he was taken away to get neutered...

He probably wouldn't ever be happy again.

"Don't worry, Mom. I won't sneak food!"

Faced with the threat of losing the two balls he'd been born with, losing weight suddenly didn't seem so difficult.

It was just eating a little less, after all.

"Jin, did your first day go smoothly?"

Uchiha Kazuna looked at her son.

"It did, Mother. The clan head made me a full member right away and appointed me squad leader, leading two trainees."

Uchiha Jin set down his chopsticks and gave a general account of the day's events.

"Wow, you're amazing, big brother!"

Uchiha Izumi looked at him in admiration, her eyes sparkling.

The Konoha Military Police Force had a strict promotion hierarchy, yet he'd become a full member and a squad leader as soon as he joined.

That was a privilege only geniuses enjoyed!

"You're amazing, Jin."

Uchiha Kazuna smiled proudly.

Her son truly was outstanding!

"Jin, you must enforce the law impartially while on duty. Don't let anyone buy you off."

Uchiha Kazuna gave her son a stern warning.

"As a law enforcer, you must uphold the law impartially. You must never show favoritism or engage in misconduct."

"I understand, Mother. I'll enforce the law strictly according to the village's rules and regulations."

Uchiha Jin nodded.

With the Justice System, of course he had to enforce the law strictly.

Only then could he earn large amounts of justice points and exchange them for things in the System Shop.

After dinner.

Uchiha Jin guided Uchiha Izumi's training in the courtyard.

In this world where the strong preyed on the weak, only the strong had a say.

For the weak, even staying alive was an extravagant hope.

The Third Shinobi World War had only just ended. From his knowledge of the original plot, he wouldn't encounter danger anytime soon.

Unless the plot reached the Nine-Tails' Rampage.

Obito Uchiha would invade Konoha posing as Madara Uchiha, snatch Naruto Uzumaki while Kushina was giving birth, and release the Nine-Tails sealed inside its Jinchūriki.

That would lead to the Nine-Tails devastating the village and the deaths of countless ninja and civilians.

The Fourth Hokage and his wife would die too.

Uchiha Jin was only two years younger than Obito and had seen him when he first entered the Ninja Academy.

Sometimes, he would also see the spiky-haired boy in goggles helping elderly women across the street.

It was hard to imagine such a good person becoming so ruthless toward even his loved ones after turning evil.

During the Third Shinobi World War, Uchiha Jin had mostly stayed with the Uchiha Main Force.

He hadn't even taken part in the battle at Kannabi Bridge.

Otherwise, he might have been able to save Obito Uchiha from his tragic fate...

Now that Obito had turned evil, he believed only in Madara Uchiha's "Infinite Tsukuyomi" plan.

He regarded himself as a savior who would create a perfect world.

Ultimately, he just wanted to escape reality.

The ocular abilities of the Mangekyō Sharingan were determined, to some extent, by the wielder's thoughts when awakening those eyes.

Witnessing the death of the person he loved had left him unwilling to accept reality, wanting to escape it.

And so the Kamui Dimension had come into being.

Uchiha Jin planned to test this when he awakened his Mangekyō Sharingan in the future.

Of course, the Mangekyō required intense emotional stimulation.

Under those circumstances, he couldn't guarantee he would be able to control his thoughts perfectly.

But there was no harm in trying.

What if it really worked?
