NO ONE'S POV:

(Inside of Yu's apartment.)

Yu: C'mon, (Y/N). Let's go!

(Y/N): Where to?

Yu: The middle of the city. There's a villain causing a panic.

(Y/N): Just go without me.

Yu: Why?!

(Y/N): I've got to study for the UA Entrance Exam, Sis.

Yu: The UA Entrance Exam isn't for months. Don't you want to see your big sister's debut?

(Y/N): Of course I do, but like I said I have to study.

Yu: Please, (Y/N)?

(Y/N): Do you really need me there?

Yu: (gives Y/N puppy dog eyes)

(Y/N): [sighs] Let's go.

Yu: Yay! Love you, (Y/N)!

(Y/N): Yeah, yeah. Love you too, Yu.

(Cut to Yu & Y/N arriving at where the villain is.)

Kamui Woods: Assault, robbery, and illegal use of powers during rush hour traffic. You are the incarnation of evil.

(Y/N): Well, sis, I guess you're gonna have to save your debut for another day. Kamui Woods seems to have things under control.

(Yu starts running towards Kamui & the giant villain.)

(Y/N): And there she goes.

Kamui Woods: Pre-emptive Binding Lazquered Chain Prison!

(Yu appears out of nowhere.)

Yu: Canyon Cannon!

Giant villain 1A: [groans]

(Everyone is shocked & some fanboys pull out their cameras & start chanting in unison: Money shot.)

(Y/N): Ugh, I've told her that her costume doesn't leave much to the imagination.

Yu: Piece of cake for the world's next hottest hero.

Yu: Hi there, everyone, I'm Mt. Lady. And you don't have to worry about this bum anymore.

(The fanboys continue to take pictures of Yu & chanting: Money shot.)

(Y/N's thoughts): If they don't stop, I swear I'm going to crush every single one of them!

Kamui Woods: Wait, she's getting all the credit?

(Y/N): I'll give it to her, that was one hell of a debut.

(Y/N then over hears a boy talking about his sister.)

???: Gigantification, huh? Well she's definitely got the looks and attitude to be a crowd favorite, and her Quirk is really showy, but it'll be kinda hard for her to get around much in the city without damaging lotsa things. That means, she might not be very useful.

(Y/N): Yo, kid!

???: Huh!

(Y/N): You taking notes on my sister?

???: Mt. Lady is your sister?!

(Y/N): Yeah, pretty cool, huh? Anyway, you are taking notes on my sister, right? And not lewding her? Because if you are, (makes his fist big) you're gonna be sorry.

???: No! I'm not! See!

(The boy shows Y/N his notes.)

(Y/N): Cool. Sorry about threatening you. It's just that, well, you've seen her costume and...

???: No, it's okay! I understand!

(Y/N): Thanks, so I'm (Y/N), and you are?

???: Izuku Midoriya.

(Y/N): Nice to meet you, Midoriya.

Midoriya: You too, (Y/N). So is your Quirk Gigantification like your sister? (pulls out a pencil, ready to take notes)

(Y/N): Yup! But unlike my sister, I can not only grow bigger in height, I can also make any part of my body bigger as well. Like you just saw with my fist.

Midoriya: That's amazing, (Y/N)!

(Y/N): [chuckles] I guess. I'm assuming you wanna be a hero?

Midoriya: Yes. More than anything!

(Y/N): So do I!

(Yu starts to call out for Y/N.)

Yu: (Y/N)! Time to go!

(Y/N): Okay, Yu. I'm coming! I guess this is goodbye, Izuku Midoriya. Hopefully I'll see you around!

Midoriya: Bye, (Y/N)!

(Y/N is now walking with Yu.)

Yu: Who was that?

(Y/N): Just a kid who wants to be a hero like me.

Yu: That's nice. So what did you think of my debut?

(Y/N): Pretty impressive to be honest.

Yu: I know right!

(Y/N): It's just that...

Yu: What is it, (Y/N)?

(Y/N): Some people were taking pictures of you!

Yu: What about it?

(Y/N): Seriously? Just look at your costume!

Yu: Oh, (Y/N), are you jealous that other people are ogling your big sister?

(Yu grabs Y/N's cheeks.)

(Y/N): Let go of me!

(Yu lets go of Y/N.)

(Y/N): I just don't like people objectifying you.

Yu: It's okay, (Y/N). It's all a part of being a hero.

(Y/N): Well, I still don't like it!

Yu: Yeah, I know. But thanks for worrying about me.

(Kisses Y/N's cheek.)

(Y/N) *blush* No need to thank me, Sis.

Yu: Let's go see if we can find any more villains for me to beat up, huh, (Y/N)?

(Y/N): Lead the way, Yu.
