Everyone thank Giova2019 for convincing me to publish two new chapters a day early.

NO ONE'S POV:

(Yaoyorozu is currently trying to convince Y/N to stick to the plan.)

Yaoyorozu: (Y/N)?!

(Y/N): ...

Yaoyorozu: (Y/N)?!

(Y/N): [sighs]

Yaoyorozu: Mt. Man?! I know you can hear me!

Years Ago

(A young Y/N is being scolded by his dad.)

(Y/N)'s Dad: Why did you hit Yu's boyfriend, (Y/N)?

Young (Y/N): Because...

(Y/N)'s Dad: Because why?

Young (Y/N): Because he hit her!

(Y/N)'s Dad: He what?!

Young (Y/N): Once he hit me back though, Yu nearly killed him. They broke up after that.

(Y/N)'s Dad: Good girl. But (Y/N), the next time you see something like that, tell your mother or myself.

Young (Y/N): [cries]

(Y/N)'s Dad: What's wrong, son?

Young (Y/N): [sniffles] I just wanted to protect her...

(Y/N)'s Dad: [chuckles]

Young (Y/N): What?

(Y/N)'s Dad: [chuckles]

Young (Y/N): Why are you laughing?!

(Y/N)'s Dad: You know, son?

Young (Y/N): What...?

(Y/N)'s Dad: Your mother and I aren't going to be here forever.

Young (Y/N): Nonsense! You and mom will live forever!

(Y/N)'s Dad's thoughts: I wish that was the case...

(Y/N's Dad ruffles Y/N's hair.)

Young (Y/N): Stop!

(Y/N)'s Dad: [chuckles] As long as you're protecting Yu then your mother and I have nothing to worry about.

Young (Y/N): Yeah!

End Flashback

(Y/N's thoughts): I'm sorry, Dad. I couldn't protect her in the end.

Yaoyorozu: (Y/N)?! Answer me-

(Y/N): Itsuka. If I don't make it back, know that I-

Itsuka: Shut up! Don't talk like I'm never going to see you again!

(Y/N's thoughts): I should've known she would respond like that.

Itsuka: Come back to me.

(Y/N): Okay.

Itsuka: Promise me!

(Y/N): ...

Itsuka: Promise me, (Y/N)!

(Y/N): I promise.

Jiro: He's already in earshot! Geez, he's fast, he'll be here in under 10 seconds!

(Y/N): For Mt. Lady. For my sister. For Yu-

(Yu's voice is heard.)

Drawn/Colored by: Hexamendle from Instagram

(Y/N): Yu's alive?!

(Y/N's thoughts): There's no time for me to be relieved! I've got to buy my friends some time!

Jiro: He's slowed down!! But only a little...

(Y/N's thoughts): Thanks, Sis. Now, let your little brother take over.

Gigantomachia: Ha! Ha! Ha! Ha!

(Y/N): Keep laughing you big bastard!

(Gigantomachia gets closer to Y/N which makes him gigantifiy for an...)

(Y/N): Ascending Uppercut!

*CRACK*

(Y/N uppercuts Gigantomachia right under his jaw but Gigantomachia is still standing.)

Yu: (Y/—Mt. Man?! What are you doing here?!

(Y/N): Protecting my sister.

(Cut to the League on Gigantomachia's back.)

Spinner: How many giants do the heroes have?!

Dabi: How annoying.

Compress: Wait, we've seen him before!

Toga: Potty mouth...

(Cut to the heroes in the forest preparing their plan.)

Jiro: (Y/N) has engaged the villain!

Yaoyorozu: We must hurry!

Itsuka: (Y/N)...

Kirishima: Don't worry, Kendo! (Y/N) is the manliest guy I know! He'll come back to you.

Tetsutetsu: Yeah!

Kirishima: A real man doesn't break his promises!

Itsuka: (gently smiles) Yeah.

(Cut to Y/N right after Ascending Uppercutting Gigantomachia.)

(Y/N's thoughts): Hmm. Back in the Practical Exam, I was able to drop Yu with my Ascending Uppercut. But this guy is still standing after it.

Gigantomachia: ...Takeyama!

Yu: [gasps]

(Y/N): You know me?

Gigantomachia: My former master told me about you.

(Y/N's thoughts): Former master? Does he mean One For All?

(Y/N remembers what All For One was telling back at Kamino.)

Memory

Past All For One: To have the ability to grow as large as Gigan-

End Of Memory

(Y/N): So you're the giant that All For One was talking about? You gotta a name?

Gigantomachia: Gigantomachia.

(Y/N): A bit on the nose don't ya think?

Gigantomachia: You're the only person who can match me in size and possibly grow larger than me.

(Y/N's thoughts): Really?! I'm only a few feet taller than Yu right now...

Yu's thoughts: Just how big can (Y/N) become?

Gigantomachia: Everything I do is for my Master. But when I kill you. It will be for myself!

(Y/N): Looks like we agree on something.

Gigantomachia: Hmm?

(Y/N): A giant dies today!

Spinner: You damn ape! Stick to the plan!

Gigantomachia: [yells]

(Gigantomachia runs towards Y/N.)

Yu: Mt. Man, move-

(Y/N): Come at me!

(Gigantomachia crashes into Y/N.)

Gigantomachia: Master! I'm coming!!

(Y/N): [groans]

(Gigantomachia is pushing Y/N back as he did Yu.)

(Y/N's thoughts): He's so strong! [groans] Would he run me over if it wasn't for Yu & Kamui Woods slowing him down?

Yaoyorozu: Hold on, (Y/N)!

(Y/N's thoughts): C'mon, Mt. Man! Do something!

(Y/N does the only attack he can think of...a headbutt.)

(Y/N): Hampton Headbutt!

(Y/N headbutts Gigantomachia's chest.)

(Y/N's thoughts): Ugh...I feel dizzy. Hitting his chest is like hitting a wall! But I have to-

(Gigantomachia suddenly grabs Y/N's right rib cage.)

(Y/N): [yelps, yells]

Yu: Mt. Man?!

(Gigantomachia starts to squeeze Y/N's right rib cage.)

(Y/N): (coughs blood) [yells]

(Y/N's thoughts): It hurts! But I'm still standing!

(Y/N): You're not getting past me you big bitch!

Gigantomachia: Master!!

Yu: (teary eyed) (Y/N)...

(Y/N's thoughts): I've got to buy my friends time-

Yaoyorozu: (Y/N)! We're ready! Come back!

(Y/N): Finally!

(Y/N shrinks back down to normal size starting at his feet & he flips over Gigantomachia by boosting himself off his shoulders. As he's in the air, he sees...)

(Y/N): The League.
