No one's POV

???: You're Naruto's son? I saw you during the sludge Villain. What's your name?

The person asked while stepping inside. A person had come to Sora's home late at night where it was supposed to be a late hour. Sora was a bit bewildered but he managed to get his words out.

Sora: Sora...Uzumaki.

Hinata: What's going on, Sora?!

Then the light that was off was suddenly on, and Hinata went out to see the commotions when he saw Sora and the other person.

Hinata: Is that really you... Sasuke?

The person named Sasuke look at Hinata and asked about Naruto's whereabout.

Sasuke: Is Naruto here?

Hinata: I think he's still at his Hero's Agency...

Sasuke: I see... Sorry to bother you.

Sora was still bewildered by the person in front of him that he didn't even realized that his Mother had come to him.

Sora(mind): This person... He's... Sasuke Uchiha. So this is Dad's Rival.

The man named Sasuke Uchiha started to make his leave, probably towards the Hero Agency that is being run by his Dad, Naruto. Reminded by his own Dad, Sora started to get even more angry.

Sora: Never mind that now... I've gotta go beat up that stupid old man!

Hinata: Sora, please wait!

Sora started to make his way out of the house that he ignored his Mother's call. Just as he was about to leave, Sasuke grabbed the back of his jacket that it surprises him. Sora tried to release the grip, but ultimately couldn't.

Sora: What are you doing?! Let me go!

Sasuke: Your mother just said to wait.

Sora: Mind your own business! This is a problem between a son and his stupid old man!

But Sasuke wouldn't budge either. He was intrigued by Sora's words when he called Naruto "stupid old man".

Sasuke: You said "stupid old man," didn't you? Were you talking about Naruto?

Sora: Who else could it be?

Sora finally stopped struggling when he realized he couldn't win against his opponent. He cooled down and stood there where Hinata gently walk towards him and grab both shoulders gently. Her gentle touch was enough to make Sora feel at ease.

Hinata: Sora...

Sora:...

Both Sora and Hinata just stared at Sasuke who was making his leave. Then surely, the sound of footsteps started to slowly disappear from his Home.

(Timeskip)

At Naruto's Hero Agency, Naruto was laying on the ground exhausted after sorting all of his work that had pile up from the day as a Hero. His assistant had told him to go home for his own daughters birthday, but he just sent a Shadow Clone.

Naruto: I messed up again.

Naruto smiled sadly when he remember what his clone had did. Due to his exhaustion, Naruto unconsciously undid his Shadow Clone that was carrying his daughter Himawari's birthday cake. A cake that Sora had bought for her birthday. Then when he was finishing up, a caught a scroll that was thrown towards him.

Sasuke: A gift from "You know who".

Naruto: Sasuke!

Naruto sat on his desk and open the scroll.

Naruto: I can't read it at all. But is it related to "Him"?

Sasuke: Yeah. Even I can't read it. He is indeed on the move.

Naruto: We better tell Toshinori, Tsukauchi and that gramps about this. Since Toshinori was the one that had defeated 'Him'.

Sasuke then told Naruto about his encounter with 'Him', how he barely managed to escape the place. How 'Him', the person's face was unrecognizable now. After he was done, Naruto sigh.

Naruto: What is that guy planning now.

Sasuke: I also met your kid. He's a lot like you when you were young.

Naruto: He's nothing like how I was. He's a lot more like you when you were young. So stubborn and reckless.

Sasuke: You mean you didn't see the Sludge Villain that happened this evening?

Naruto:...? No... I didn't. Did something happened?

Naruto asked confusingly. Sasuke sigh at Naruto's denseness. He didn't say anything and started to make his leave.

Sasuke: No. Never mind. But let me tell you this, Naruto. The soul of a Hero always remains the same... even if times change.

Naruto just gave a smile.

Naruto: I don't want to hear from a Vigilante like you.

Sasuke: Hmph. You damn loser.

(Timeskip)

As Sasuke was making his leave, he saw a certain figure rushing towards the place. There he met him at the front gate where he saw Sora whom was also surprise to see him.

Sora: Uncle Sasuke?

The reason why Sora was able to make it here was because he had gave the slip when his Mother went to bed. He jumped off his bedroom window and rushed towards the Agency where he knew his Dad would be there. But he wasn't expecting that Sasuke would be waiting him at the front gate.

Sora: D-Did you just see my dad?

Sasuke: My business with him is finished.

Sora: I-I see.

Sasuke: You wanted to beat up Naruto, didn't you?

Sora: Yeah. If you're gonna interfere... I'm not holding back!

Sora went to rush towards Sasuke so he could break through and head towards inside the building. But just as he gets closer to Sasuke, he was already blown back by a single kick by the Vigilante.

Sora: Guh! What the...?

Sasuke: You think you're ready to take him on like that?

Sora(mind): The kick was so fast I never saw it coming.

Sora gritted his teeth. He's even more angry than usual.

Sasuke: Here's some advice. The way you are right now, yo'll never get close to him. Just go home before you get hurt.

Sora: Don't get in my way! Shadow Clone!

Sora created three clones of himself and all 4 of them rushed towards Sasuke. But his clones never even get close to hitting the Vigilante. With just a single kick to each clones, they all disappear in an instant. Then the real Sora was already apprehended.

Sora: So strong.

Sasuke: Satisfied?

Sora: N-Not yet! G-Gah!

Sasuke tighten his grip on Sora's arms that he started to scream in pain. But Sora shows no sign on giving up at all. Seeing his determination and resolve to beat up Naruto made Sasuke let go of him and Sora drop to the ground with his left hand holding his right hand in pain

Sasuke: Now you know... the level of your strength and his?

Sora could only grit his teeth when he saw the big gap within their strength. And knowing that this Vigilante in front of him was his Dad's rival made him realized even more just how naive Sora could be. Thinking he could win against his own Father when he could not even stood up to his Rival.

Sora: I-I know exactly just how strong my dad is! But still—

Sasuke: Why are you so hung up on Naruto?

Sora finally let out his loose emotions. All the times where he would saw his Dad in Television always made an impression on him. How he would see Naruto with his Shadow Clone helping the citizens. How using his Wind Quirk to took down his enemies. He know just how big the gap was.

Sora: If this keeps up. Our Family will truly fall.

Sasuke:...

Sora: He started neglecting us after the incident that happened 5 years ago.

Sasuke: 5 years ago? You mean the Highway Bombing Incident?

Sora slowly nod his head.

Sora: We lost someone precious that day. And ever since then... My dad.

Sora started getting more and more upset with each passing moment. His Dad started doing more work that he started to neglect his own family. He would always late for home. Never paying attention to his own child achievements and growths. Then with resolve eyes, he looked at Sasuke declaring his thoughts.

Sora: Uncle Sasuke! Please make me your student!

Sasuke: Student?

Sora bowed his head.

Sora: Please... I just have to proved my Dad, no matter what it takes!

Sasuke: Why would you go that far to rebel against your father?

Sora: He sent a Shadow Clone to my little sister's birthday! Mom always told me, that Dad "Never go back on his words"! But, he broke our sacred man-to-man promise! There's no way I can't forgive him!

Sora continues to bowed his head towards Sasuke. His hand were gripping tightly that blood started to drip.

Sasuke: Being a Hero is a difficult job. There are circumstances beyond his control.

Sora: I know. But I'm sick of it! All he ever does is treating me as a Kid that he never realized just how grown I've gotten... But also—

Sasuke: Also?

Sora: If this continues on. Our family will truly fall into ruin. My mother, my little sister, including myself are already reaching the limit of our patient. So please, I— No, none of us want to grow up without knowing what its like to be loved by a Father! If words are not enough, than I have to show him by actions! Please, I beg of you!

Sasuke could feel the weight of every words that Sora had put into it. He could sense Sora's determination and resolve in order to make his father regret ever neglecting them. Seeing him like that reminded him of how both him and Naruto were like when he was little.

Sasuke: Can you do the Rasengan?

Sora look up surprise before looking down at his hand where blood flows out after gripping his hand tightly.

Sora: The Rasengan? It's not complete yet. Since my Dad never try to teach me how to do it.

Sasuke: I saw you do it during the Sludge Villain. It looks perfect to me.

Sora: That was the first time I ever made it that big. Normally its smaller.

Sora started to perform his usual Rasengan. And just like he suspected, the Rasengan didn't come like he did during the Sludge Villain.

Sasuke: It's awfully small... I'd be hard pressed to call that a Rasengan yet. The one that you showed this evening is more bigger.

Sora looked down saddened.

Sora: That's what I was trying to tell you. I'm basically self taught here. So I can't become your student.

Sora said resigning thinking he could be Sasuke's student. With a defeat sigh, he threw away the small Rasengan to a nearby tree. The Rasengan disappear into thin air. He started to walk away. But still, he wouldn't stop here until he could beat up his old dad. But Sasuke wasn't done.

Sasuke: You're jumping to conclusion here. I never said no.

Sora: Huh?

Sora stopped and look at Sasuke with hope in his eyes.

Sora: So...? That means...?

Sasuke: Fine... You can be my student.

Sora: Hell yeah!

Sora shouted with excitement.

Sasuke: Meet me tomorrow morning at the forest in the mountain.

Sora: Yes, sir!

(Timeskip)

The next morning, at the crack of dawn, Sora indeed met up with Sasuke to start their training session. At first Sasuke wanted to see his combat ability, so Sasuke asked Sora for a spar. And they did just that, from morning until the evening, all they did was train.

Sasuke: Your right arms tends to move upwards! Lower them even more!

Sora: Yes!

Sora transform his vow to overcome this trial into kindling, and the flames of his spirit roar as he let loose a battle cry that reaches the heavens.

Sora: H​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​a​!

Sora's uppercut with his right hand and unleash a horizontal punch with his left. They are both deflected by Sasuke being spun at high speed like a fan, but still Sora advance.

A thunderous clash of fist rings out. The rhythm of fights echoes across the fields. At some point, the refrain of attack and counterattack composed all around them fades, until only theirs remains. Sora focus every bit of his attention on the opponent in front of him. Sasuke's fierce rush toward Sora with a sharp whoosh.

Sora pull through by slamming it from the side with his elbow. His skin is just barely got hit by Sasuke's strike as its path shifts by the tiniest of increments, and then Sora mount his counterattack, performing a rush that takes full advantage of his speed and number of attacks.

Sasuke: Not bad. But—

Sora: Gah!

While Sora was blinking away the sunlight, Sasuke somehow teleports right in front of him before delivering a magnificent kick right to his stomach. Sora already used every last bit of energy he had left, so he can't defend against it. All Sora could do was crumple and fall to the ground with a muffled grunt.

Sora(mind): Master is the same as always...!

Sasuke: You're being to naive. It's already sunset. Let's take a break.

With that, Sasuke turn his back and began to walk away. Sora stare his back before standing up to his feet and followed him. They started a bond fire and Sora brought up the lunch and drink that his Mother and Little Sister pack for him.

Himawari: Hang in there and do your best, Big Brother! Himawari.

Sora smile when he saw the letter his little sister sent for him. Then after he was done with his meal, Sora look at Sasuke.

Sora: Hey, tell me everything about my Dad.

Sasuke: When he was a kid, all he did was talk about becoming a Top Hero, and he was a total loser.

Sora: A total loser?

Sasuke: And a damned stubborn.

Sora: No, not that at all! What I really wanna know about are his weaknesses.

Sasuke: Weaknesses?

Sora: Yeah.

Sasuke: I don't have enough fingers on my hand to count. He was the stereotypical loser, full of weaknesses. But he overcome them with his own strength, and become the Top Hero of his Dream.

Sora:...

Sasuke: Maybe instead of the Naruto of today, you should study the Naruto who made it this far.

Sora:...

Once again, Sora fell silence. He continued to think what Sasuke's words meant. The Naruto that made it this far is the Naruto Sora needs to learn. Sora couldn't come up with an answer at all. After training for an entire day, Sora made his way home. But he was completely drained from his training. He arrived so tired he practically slump on his bed. Then, he got a message from Izuku that he too was training with All Might. Telling him that he saw Sora training with Sasuke as well. Reading this, Sora smile.

Sora: Like a peas and pod.

(Timeskip)

10 months later.

10 months have passed since Sora had started training with Sasuke. Sora's physical strength and the strength of his quirk has increased exponentially. Normally he could only create 4 clones. Now he could create up to 15 clones. And the strength of his wind also increases. After graduating from middle school, Sora was now on his final day of training with Sasuke.

Sora(15 years old): Thanks for everything, Uncle!

Sora said bowing his head. Today was the day he turned 15 and also the day before U.A entrance exams. He bowed down to Sasuke for all the things he had done this past 10 months.

Sasuke: Be proud. You made it this far thanks to your own efforts.

Sora: Hey...

Sasuke: Hm...?

Sora: Did my Dad also went through such rigorous training to made it these far?

Hearing this Sasuke smile. Sora's dirty clothes and face truly reminded him of how he and Naruto were when they were younger. An eye filled of wanting to become strong for something precious.

Sasuke: Seems you want to know more than just his weaknesses now.

Sora:...

Sora didn't say anything. But his silence was all Sasuke need to know that Sora indeed wanted to know.

Sasuke: But you should ask him yourself. That's not for me to tell.

Sora: I see...

Sasuke: Listen carefully, Sora. Becoming a Hero is no easy job. You'll be face with crushing pain and reality. But knowing that, are you more than resolved enough to risk your life for the sake of people who might scorn you if you didn't do your job properly?

Sora: Um...

Sasuke: You're actually a strong person. I lost to your dad, but if you put your mind to it, you can become the Hero who can defeat him.

Sora: Really?

Sasuke: You definitely can.

Sora: Huh?

Sasuke: Because you're a bigger loser than Naruto ever was.

Sora: A loser? What does—?

Sasuke: I mean that you hate to lose. I'm saying you can do it. Trust my words.

Hearing this, Sora couldn't help but smile. Seeing that his Master had put that much faith in him made him even more determined to beat his dad.

Sora: Yeah!

Sasuke: Good. Here, I have a present for you.

Sora: Present?

Sasuke pulled his right hand out and handed Sora his Present.

Sora: This is...

Sora looked surprised. The present that Sasuke had given him was Sasuke's own headband.

Sora: Isn't this yours?

Sasuke: I threw it away long ago, but your father kept it safe for me all this time. We made a promise then. That I would keep it until the day we could have a real fight. I'm giving it to you.

Sora:...

Sora didn't say anything, but slowly put the Headband on. Sasuke could only smirk.

Sasuke: It's very important to me. Take good care of it. Some day... Return it to me... As a great Hero. It's a promise, Sora.

Sora: Yeah!

With that final words, Sora and Sasuke, the Master and Student. Former Hero, now Vigilante. And the boy who dreamed to become a greater Hero than his Dad, take their final goodbyes and walk their separate ways.
