Izuku: Is... Is everyone ok?

Katsuki: All right over here, Deku.

Tanjiro: That could have ended a lot worse if it weren't for Blackwhip.

Nezuko: Brother! Izu! Everyone!

They all looked to see Nezuko running to them.

Nezuko was hugging him so tight, he felt like she might break his spine.

Nezuko: I was so worried about you all!

Izuku and Tanjiro hugged her back.

Tanjiro: It's ok, Nezuko. It's over now.

The gang looked around. The entire district was completely destroyed by Gyutaro's last ditch attack.

Shoto: We would be part of that place had Izuku not protected us.

Zenitsu: WHY DO I HURT ALL OVER?!

Katsuki: Aaand he's up.

Izuku: Calm down Zenitsu. There's nothing to fear. There aren't any demons here.

Nezuko: Inosuke. Are you alright?

Nezuko could feel his heartbeat getting weaker and weaker. In panic, she transformed into her awakened form and her horn started to glow. It then released a bright beam of light at Inosuke and after a few minutes, he was healed. Nezuko transformed back and was shocked at what had happened.

Izuku: That was...Rewind!

Tanjiro: Eri's quirk?!

Izuku: I guess in her awakened form, she's able to use Rewind from her horn like Eri does.

Katsuki: Hey, Boar-face, how are you feeling?

Inosuke: ...I'm starving! Give me something to eat!

They all sighed in relief.

With Uzui and his wives, Suma was freaking out about how Uzui was about to die because of how beat up he was. The others were crying.

Suma: The antidote still isn't working! How are we supposed to deal with demon poison?! Why is God so cruel?! Why?!

Uzui: Listen closely, for these are my last words. My life, up until this very moment...

Suma was crying a lot and Makio was incredibly angry that she was talking over his final words. The three were arguing.

Uzui: 'You're kidding. Am I gonna die without saying my last words? The poison's starting to make my tongue stiff. What am I suposed to do? I could've left those last words, but... seriously?'

Izuku and Nezuko then show up.

Izuku: It's going to be alright. Now that Nezuko is here, that is.

Nezuko transformed into her awakened form and began to use Rewind on Uzui. Bringing him back to full health, AND bringing back his hand. This surprised Uzui and his wives.

Suma, Makio, and Hinatsuru: LORD TENGEN!

All three hugged him while crying.

Uzui: Sorry, you three, for making you worry. What was that?

Izuku: Rewind. Eri's and apparently Nezuko's quirk. It allows the user to rewind a living being back to a previous state of existence. Eri used this quirk to turn Nezuko back into a human. Although it led to some side effects for unknown reasons that fused her DNA with Nezuko and gave her a quirk. Or in this case, two.

Izuku then notices Tanjiro looking around.

Izuku: Tanjiro? What are you looking for?

Tanjiro: I need to find the demon's heads so I can obtain some of their blood to give to Yushiro and Tamayo.

Izuku: May I ask why?

Tanjiro: To make a cure for the people who were turned into demons.

Izuku: Then I'm coming. Let's go.

The two rush off to find Daki and Gyutaro's heads. Eventually they come across a puddle of their blood. Tanjiro threw a rock at the puddle to see if it was dangerous. It was not. He then collected the blood with his tool...thing.

Cat: Meow.

Izuku: A cat? Where did-

Just then, Nezu pops out of the cat's pouch.

Nezu: Why thank you for giving the blood of an Upper Rank, Tanjiro Kamado.

Izuku: NEZU?!

Tanjiro: You know him?

Izuku: He's the principal of my school.

Tanjiro: ......What?

Izuku: Nezu's quirk gives him incredible intelligence. He can really come through in a fight, despite his size.

Nezu: Now, if you'd be so kind as to give that blood sample.

Tanjiro: Oh, uh...s-sure.

He gives Nezu the blood sample.

Nezu: Thank you very much.

He then goes back into the pouch and the cat leaves in a reddish smoke.

Izuku: So...that just happened. Anyways, let's keep going.

Tanjiro continues to lead the way to the decapitated heads. However...

Gyutaro: I CAN'T BELIEVE YOU GOT BEHEADED BY A COUPLE OF AMATEURS!
Daki: SO YOU WERE WATCHING AFTER ALL! WHY DIDN'T YOU SAVE ME, THEN, HUH?!

Izuku: Are they...

Gyutaro: I WAS TOO BUSY BATTLING A HASHIRA!

The two were arguing while they were starting to disintegrate.

Daki: I DON'T CARE IF YOU WERE! YOU SHOULD HAVE FINISHED HIM OFF WHEN YOU HAD THE CHANCE! YOU COULD HAVE JUST SPLIT HIS HEAD WIDE OPEN!

Gyutaro: AND I WAS ABOUT TO!

Daki: YEAH, RIGHT!

Gyutaro: BUT THOSE KIDS WERE SOMEHOW STILL ALIVE, SO I FIGURED I SHOULD KILL HIM OFF FIRST! SINCE YOU WEREN'T DOING A DAMN THING TO HELP OUT, YOU SHOULD HAVE BEEN THE ONE TO FINISH OFF THE HASHIRA!

Daki: WELL, MAYBE YOU SHOULD HAVE JUST CONTROLLED ME SO I COULD DO THAT! BUT INSTEAD YOU WENT AND LET YOUR GUARD DOWN AS USUAL!

Gyutaro: SHUT YOUR MOUTH!

Tanjiro: They're still alive?

Izuku: So THIS is what siblings fighting looks like.

Tanjiro: You've never seen that?

Izuku: I'm an only child, so no.

Daki: YOU'RE THE ONLY IDIOT HERE!

Gyutaro: WHAT'D YOU SAY?!

They were panting and out of breath from all the insults. And then...

Daki: A hideous person like you couldn't possibly be my brother.

Izuku and Tanjiro started to feel bad now. Not about decapitating them, no. But what Daki just said. Izuku then started to walk towards them.
Daki: I mean, just look at you. I bet we're not even related by blood, not with how ugly you are! AND NOW YOU'RE USELESS! YOUR ONE SAVING GRACE IS YOUR STRENGTH! AND THAT'S ALL YOU EVER HAD! YOU'RE COMPLETELY USELESS IF YOU END UP LOSING, SO YOU'RE JUST A WORTHLESS, UGLY FREAK NOW!

Gyutaro was in shock at what she just said. He then became angered.

Gyutaro: DON'T GIVE ME THAT CRAP! IF YOU WERE ON YOUR OWN, YOU'D BE DEAD NOW! HOW MANY TIMES HAVE I SAVED YOU?! You're the worthless one, and you know it. You're too weak to stand on your own two feet. I can't believe I wasted my entire life protecting someone as useless as you. IF IT HADN'T BEEN FOR YOU, MAYBE I WOULD HAVE DONE SOMETHING WITH MY LIFE! MAYBE I WOULDN'T BE DYING RIGHT NOW! IF ONLY-

But then...

Gyutaro was experiencing unbearable pain. Daki looked in Izuku's eyes to see that he showed no remorse for it. Without thinking, she yelled at him.

Daki: STOP IT! LET GO OF MY BROTHER!

Izuku just looked at her and talked in an emotionless tone.

Izuku: I thought you said that there was no way he could possibly be your brother.

He began to jab Gyutaro's head with more Blackwhip.

Daki: PLEASE! JUST LET HIM GO!

Izuku: Why do you care? I thought you hated each other. I thought you'd be glad to see your "brother" being tortured like this.

Daki: WE WERE JUST FIGHTING! DON'T YOU EVEN KNOW HOW SIBLINGS FIGHT?!

Izuku: I wish. But how would I know?

Daki stopped talking and began to listen.

Izuku: I'm an only child. I never had a sibling. I always wanted a brother. Someone to play with. Someone to cry on. Someone who would support my dream instead of almost everyone else who made fun of me for it. But I don't have one. And it's not like I can expect one anytime soon. My father works overseas. So I never had another guy to bond with until high school. I would love to have a brother. Maybe a sister. But I don't. I actually envied you two.

Gyutaro: Wh-What?

Izuku: I envied you. I saw you two had such a strong bond with each other. I was envious of that sibling love you shared. Are you two really just going to throw it all away? Over this?

Izuku lets Gyutaro's head go.

Izuku: Let me ask you...what you've been saying to each other, do you really mean it? If that's the case...

He then stomps on Daki's head. Multiple times. Despite her screams of pain.

Izuku: Then you won't mind me doing this.

Gyutaro could only watch, enraged. And then...

Gyutaro: LEAVE UME ALONE!

Izuku stops.

Izuku: "Ume"?

Gyutaro: ...That's right... My little sister's name was never Daki. It was...Ume.

Daki: I had...forgotten...how could I have forgotten...my own name?

Izuku: ...

He takes his foot off of Daki's head.

Izuku: ...Because your past as humans was erased from your memory. You forgot everything about your life except that you two were siblings. Are you still going to throw that away?

Gyutaro and Daki...no...Ume looked at each other.

Gyutaro and Ume: NO!

Izuku: Then what are you going to do? You still have a bit of time before you go to hell.

Ume and Gyutaro look at each other again.

Gyutaro: Ume...I'm sorry. I didn't mean the things I said.

Ume: I'm sorry too. I didn't mean it. You are my brother.

After saying those words, the two fully disintegrated. But not before they saw Izuku's face one last time. And what they saw made them feel relief.

Tanjiro came up to Izuku.

Tanjiro: Did they make up?

Izuku: Yeah. I didn't like having to go to the extreme...but I had no choice.

Tanjiro: So...it's finally over. I've never been so tired.

(Meanwhile with Uzui)

Iguro: Unfortunately that would be the lowest of the Upper Ranks. Well, Six or not, you still defeated an Upper Rank, so I believe congratulations are in order. Though it was Six...I guess you've earned some praise.

Uzui: I don't know if that was a compliment or not, but thanks.

Makio: You took your sweet time getting here.

Suma: Y-Y-Yeah, you showed up after all the fighting! How convenient!

Iguro's snake hisses at her and she screams.

Iguro: What exactly do you plan on doing now? You'll need a replacement while you recover from this. Any ideas of who can fill in for you until then?

Uzui: I'm actually retiring. There's just no way I can still fight. My organs are pretty mashed up. I'm sure the master will understand that much.

Iguro: Don't be ridiculous. I don't allow it. Too many swordsmen have fallen for you to consider retiring. You'll fight until you perish.

Uzui: Nah. I know just the two swordsmen to replace me. Do you remember those new kids that you love to hate?

Iguro: What? You're joking. You mean they survived? A battle like this? Tanjiro Kamado and Izuku Midoriya survived?

(Meanwhile with Kagaya Ubuyashiki)

Kagaya: You're positive? They defeated two Upper Rank demons? You have my thanks, Tengen, Tanjiro, Nezuko, Zenitsu, Inosuke, Shoto, Katsuki, Izuku!

He starts coughing in pain.

Kagaya: One hundred years. It took 100 years to finally change, and it actually happened. Amanae...

Amanae: Yes?

Kagaya: Don't you see? This must be an omen. Fate is about to take a dramatic turn for us. The effects will be widespread. Everything will be shaken to its core. And eventually, he will feel it as well. Muzan Kibutsuji... we will defeat you. Our generation... and our superpowered friends from the future, will put an end to you without fail, and then you, the sole blemish of my family, will be gone.

(Meanwhile)

Akaza was there.

Akaza: The alternate dimension... The Infinity Castle. The fact I was summoned here can only mean one thing. They managed to kill an Upper Rank.
