Sasuke's Older Brother

Jin silently refined his chakra. His furious heart was already on the verge of going berserk. Before his eyes, there was nothing but darkness.

Just then, Jin felt something bump against his calf. "Ow! What was that? Damn it, it's pitch-black—I can't see a thing! Could someone outside have bumped into me? You dare hit even a pregnant woman? You must be asking to get struck by lightning! Just wait until I get out of prison, you little punk. I'll cripple you!" Jin kept indulging in wild fantasies.

"Ow, are you done yet? No, that's not right. It seems to be inside this prison. Could it be... Heaven! Don't tell me it's a twin! Then I have to be the older brother! I can't be Number Two! Hehehe, we'll see who gets out first."

"Ow, you kicked me again! Go on, kick me. I'll kick you back too. No, this is a fetus! If I accidentally kill it, I'll get struck by lightning! I'll endure it. Just wait until your brother gets out! You little brat! Whether you're Orochimaru, the Nine-Tails, or Madara, just wait to get crushed!"

"Big Brother! Stop kicking!" Jin kicked him. "The world is finally quiet! Time to train!"

...Several days later...

"Hahahaha, ohohoho! I've finally trained up to genin! Oh no, where did this huge force come from? Why won't my body obey me?!" A sharp pain suddenly shot through Jin's mind. It hurt so badly that he screamed, venting the frustration in his heart.

A baby's cry rang out, rescuing Jin from the pain.

Then he heard a woman say, "Congratulations, madam. They're twins!"

A storm surged in Jin's heart. Am I the older one or Number Two?

A man's voice sounded. "What? Two sons? Twins! Wonderful! I, Uchiha Fuchiu, have two sons!"

A young boy said, "Father, I'm your son too."

Uchiha Fuchiu said joyfully, "Of course. Itachi is my son too. Father is just too happy. Itachi, from now on, you must take good care of your two younger brothers! You're the genius of our Uchiha Clan. I'm sure your younger brothers won't be lacking either. They're six years younger than you, so I'll leave their training to you in the future. After all, the age gap between you isn't that great."

Itachi nodded happily. "Mother, are you all right?" Out of the corner of his eye, he saw the eager look Father Uchiha Fuchiu was giving Mother, so he added, "You should get plenty of rest. I'll leave first." Before leaving, he glanced at his two younger brothers.

After that, Uchiha Fuchiu and his wife began naming the two children.

Ever since Jin heard their conversation, his heart had been unable to calm down for a long time.

He sank into thought. Fuck, I'm actually twins with Sasuke Uchiha! So who the hell is Number Two? Nobody ever mentioned this! What am I supposed to do when the clan massacre happens? I'm only a genin. Even if you gave me another four years, I might only reach chunin, but that would still be useless! What do I do?! It would've been great if I'd been born somewhere else! Then I could have pretended to be someone else. Now, maybe I'll be killed four years from now too. Damn it...

News that Uchiha Fuchiu had fathered twin sons quickly spread. The heads of the major clans came one after another to offer congratulations.

At this time, Jin was devising a plan—a naming plan.

Jin began saying only one word every day: "Jin."

The result was obvious. Jin got his wish, while Sasuke remained Sasuke.

In the blink of an eye, a year passed. Jin finally learned the answer to a question he had been investigating for a long time: he had been born ten seconds before Sasuke. He was the older brother, and Sasuke was Number Two. However, what depressed him was this—Itachi was Number One, Jin was Number Two, and Sasuke was Number Three. Depressed...

When he turned one, Jin felt that his chakra reserves had increased considerably. By all rights, he should have reached level twenty, only ten levels away from becoming a chunin. Yet none of his skills had leveled up! This left Jin deeply confused.

It was not until one night, when Jin saw Itachi Uchiha practicing various hand seals at one of the clan's training grounds, that he suddenly realized—skills were leveled through proficiency.

Thinking of this, Jin muttered to himself, Damn, Itachi really is a genius! But no matter how much of a genius you are, are you more gifted than your parents? They gave birth to three geniuses! Hahaha, I really am a genius.

"Then which one should I practice first?"

Jin thought for a day and a night before finally deciding to practice the Multiple Physical Shadow Clone Technique first!

{Genius! What is a genius?! The parents of Uchiha Jin and Sasuke Uchiha are geniuses!}
