Izuku is seen walking towards the Butterfly Mansion, beside him is his harem... Kota holding Mitsuri's and Shinobu's hands, while Eri is riding in her father's shoulder, while holding Kanao's and Nezuko's hands for support...

Tanjiro: Hey Izuku, How come you were not surprised about meeting the other you?

Izuku: Well, our world has quirks so it is possible to do that

???: He has a point

They looked for the one who spoke.

Izuku Y.: It's me...

Izuku: Yo, what are you doing here?

Izuku Y.: I forgot to give you the gift for passing the final selection, here.

Izuku: What is this?

Izuku Y.: The nine-seals.

Izuku: So I can unseal the seals?

Izuku Y.: Unfortunately, No... But it gives you a sacred breathing.

Izuku: Wait what?!

Izuku Y.: Yeah the Life Breathing... You have access to whether kill or revive someone...

Izuku: What's the catch?

Izuku Y.: Nothing, everytime you revive someone you will meet Death or the Grim Reaper... Just tell them you have the seal and they would understand it...

Izuku: Okay... But why give this to me?

Izuku Y.: I'd rather give it to you than keeping it locked in somewhere... Keep it safe and don't worry about losing it, it'll comeback to your wrist if you dropped it.

Izuku: That's so cool!

Izuku Y.: Well then, I'll have to leave now Momo is searching for me, and we both know not to make her wait...

Izuku *shivering*: Don't remind me...

Izuku Y.: Bye!

Shinobu: Darling~ we should hurry up it's almost noon.

Izuku: Let's go

When we arrived, Shinobu pulled me towards her office to be checked, and the rest of the girls followed us, while tanjiro was taken to the clinic along with Eri and Kota.

Shinobu: Okay darling, let me see your body.

Izuku: W-what?!

Shinobu: I need to check if you have broken bones

Izuku: Okay

I saw them blush, and Shinobu composed herself to examine my body.

We visited the clinic after she finished examining and feeling my body... When we reached we were met by a loud scream...

???: NO! I DON'T WANT TO DRINK IT!

???: YOU HAVE TO, IF YOU WANT TO BE CURED!!!

Tanjiro: Zenitsu! Just drink it!

Zenitsu: No!

Izuku: Yo! Tanjiro, so how is your body?

Tanjiro: Just some bruises and broken ribs

Zenitsu: You! You're the one who has a girlfriend aren't you, you lucky bastard!

Izuku: I don't have a girlfriend... I have girlfriend'S'

Zenitsu: HUH?! HOW MANY DO YOU HAVE?!

Izuku: 4

Zenitsu: HUH?! AND I GOT NONE YOU! WILL BE PUNISHED IN THE NAME OF THE PEOPLE WHO DOESN'T HAVE LOVE!!!

Izuku:

Zenitsu fell asleep, after being hit by the thorns.

Shinobu/???: That was helpful thank you Izu/Mister...

Izuku: It's fine Shinobu... And who are you Miss?

Tanjiro: I see adding another one... Huh? More niece for me then...

Aoi: I'am Aoi Kanzaki... And what do you mean by that Tanjiro?

Izuku: I'm Izuku Midoriya, The Nature Hashira but just call me Izuku, and Just... Don't mind him...

Aoi: I'm sorry, Hashira-sama, I didn't know there was a new Hashira.

Izuku: It's fine, I don't like others to feel inferior to me... So just treat me like a friend, Okay?

Aoi: Okay...

Izuku: Where's Tanjiro?

When I looked at Tanjiro I noticed him talking to the girls...

Tanjiro: Right, so you're okay with this?

All 4: Right!

Izuku: Tanjiro, what did you talked about?

Shinobu: Ehem... We have decided to add Aoi to your Harem.

Izuku/Aoi: What?! Do I have a say in this?!

Shinobu: No...

Izuku: *sigh* Anyways where are Eri and Kota?

Tanjiro: Their asleep in the bed...

Izuku: Okay...

Aoi: Does this always happen to you, when they saw a new girl?

Izuku: More or less...

Aoi: And you don't argue with them?

Izuku: I learned from experience to never argue with a woman, it's bad for me...

Mitsuri: Hey Izu, can you help me buy clothes for Eri and kota?

Izuku: Okay, when?

Mitsuri: When they woke up... So we can be sure to their sizes...

Izuku: Okay.

Shinobu: After that help me with moving a few equipments

Tanjiro: Oh, Inosuke is here too.

Izuku: Inosuke?

Tanjiro: He's a demon slayer, a noisy one that is... He always likes to fight...

Izuku: Where is he?

Tanjiro: there, feeling depressed that he lost a fight...

Izuku: I know! Hey! Inosuke!

KOTA

We left and I went to Shinobu's office to move the equipments which didn't took long, and after two days, I'll help Kanao and Aoi in the Rehabilitation.

It was night time and I saw Nezuko went up to me with a pout...

Izuku: What's the problem Nezuko?

Nezuko: Cuddles!

Izuku: Okay... Come on

e snuggled each other in her bed, A few minutes later the door opened and Shinobu, Kanao, Mitsuri and Aoi all entered the room...

Izuku: Hey, girls! Let me guess cuddles?

All of them nods, Aoi was a little hesitant...

Izuku: Come here then.

Izuku: We need a bigger bed...

Girls: Yep...
