No One's P.O.V

Izuku and Tanjiro are walking towards Urokodaki's house, Tanjiro was barely hanging on, while Izuku was walking like nothing happened, they've been walking for two days, but he was still fine...

Tanjiro*panting*:How are you not tired?!

Izuku: I might have been blessed by god...

Tanjiro: Lucky you...

Izuku: Just a little luck of course

Tanjiro: But how can it be a 'little' bit of luck if you're literary a chick magnet? Like now you're going to another girls house after you got yourself a girl...

Izuku: TANJIRO!

Tanjiro even though he is tired, ran for his safety and he is still laughing at Izuku... They arrived after a few hours, they were met by Nezuko waving at them.

Nezuko: Nii-chan...

Tanjiro ran up to nezuko and hugged her.

Tanjiro*crying*: Nezuko! What happened why did you fell asleep for two years!?

Nezuko: Sorry, Nii-chan... I think I need sleep, if i don't want to eat humans.

Tanjiro: It's fine... just warn me next time about it.

???: You've return! Tanjiro...

Tanjiro: Yes Mr. Urokodaki

Urokodaki*crying*: I'm glad, you've return

Tanjiro: By the way Nezuko, Mr. Urokodaki this is Izuku he just went from the north so he has no place to stay...

Urokodaki: How far are your home in the north?

Izuku: W-well, let's just say, really far...

Urokodaki: Well I'm not gonna force more question, your welcome to stay here all you want.

Izuku: Thank you, I appreciate your generosity...

Urokodaki: It's fine...

They walked inside and Urokodaki prepared them food, for their long journey...and he went to sleep to rest his body from finding woods... Izuku always feels that he was being looked at... He looked to see Nezuko looking at him with a blush...

Izuku: DAMN IT NOT ANOTHER ONE!

Tanjiro noticed Nezuko and smirked.

Tanjiro: HAHAHAHA IZUKU YOU WILL BE MY BROTHER IN LAW BY THE END OF THE WEEK! Nezuko... Do you like Izuku?

Nezuko nods with a blush...

Izuku: I'm sorry Nezuko but I already have-

Tanjiro: Fallen for you! Nezuko you don't mind sharing Izuku right?

Nezuko: I... Don't, why?

Tanjiro *looked at Izuku with a smile and a thumbs up*: MY BROTHER!

Izuku grow a tick mark, but was immediately tackled by Nezuko...

Izuku: N-nezuko what are y-

He wad interrupted by a kiss... Nezuko was kissing him and after a few second, he melts into it... Tanjiro was crying tears of joy for having a brother.

Nezuko: Do you love me?

Izuku: Damn it! Call me a two timer but I did enjoyed the kiss... Y-yeah, Nezuko I do love you...

Tanjiro: Yes a brother! Now you have started to make your harem Izuku! First, Kanao, then Nezuko, you became my brother, man I'm happy...

As Izuku sweatdropped at him, he feel a tug on his haori, he looked and see Nezuko pouting...

Izuku: Nezuko, what's the problem

Nezuko*pouting*: Who's Kanao?!

Tanjiro & Izuku: Damn it!

Izuku: She's a girl, I meet from the Final Selection and she is kinda my... Umm... Girlfriend...

Nezuko: We just got together and you're already cheating!

Izuku: N-nezuko please don't be mad at me... Your brother was the one who made us a couple...

Nezuko looked at her brother with a glare: Is this true Onii-chan~

She said with a calm but scary voice.

Tanjiro: W-well m-maybe...

He ran outside and was being chased by Nezuko.

Timeskip

15 days have passed since that... umm... incident... And me and Tanjiro are waiting for his sword outside the house, when Mr. Urokodaki asked me a question.

Urokodaki: Izuku you've stayed here for almost two weeks but I still don't know what breathing style you use...

Izuku: Oh it's Nature Breathing, it allows me to use all breathing that is from nature but I mostly used Ice and Thorn Breathing...

Urokodaki: So how many forms does those two breathing have?

Izuku: I don't actually know... I just use what I know...

Urokodaki: Hmmm... so you only do everything on instinct?

Izuku: Maybe...

After an hour, his sword arrived and a man named Haganezuka told us about the legend of some sort... I don't know...

A day after Tanjiro's Mission arrived.

Crow: Tanjiro! Tanjiro! You must head to a town Northwest from here! Go!

Eagle: Izuku, you are given a task to hunt for the Lower Ranked Demons and kill them immediately!

Izuku: So I guess will see each other someday huh? Tanjiro...

Tanjiro: I guess...

Izuku: Nezuko, I'll see you in a few days if I make it quick.

Nezuko: No!

Tanjiro: Come on Nezuko, it's just a few days or maybe weeks...

Nezuko: No! I'll come with Izuku!

Izuku: You can't, I'm going to fight strong demons... So you can't come with me...

Nezuko: No! I'll come with you! No matter what!

Izuku: *sigh* Tanjiro what are we gonna do no-

I looked at Tanjiro to see him having a somewhat a scary happy smile... having a thumbs up...

Tanjiro: It's fine, And please I want a niece or a nephew.

Izuku: Oi! Too Early!

Tanjiro: Well then, I'll see you guys in a few days!

We left on our own missions...

Nezuko and I, are walking towards Mt. Natagomu, since The last of the lower ranked demons is here.

Over the past few days, We found out that Nezuko can walk in the sun due to an accident... While on a break...

We arrived to the Lower Ranked Demon, defeated by a Hashira... Giyuu Tomioka... The water Hashira...

We went towards him and I thanked him.

Izuku: Thank you for defeating the Lower Rank Demon for me...

Giyuu: So you were the one who was given the mission to hunt down the Lower Rank Demons...

Izuku: Yes, Tanjiro you okay man?

Tanjiro: Yeah just a little scratch...

Nezuko went to him in a worried face

Nezuko: Hmmmm...

Izuku: Nezuko his fine... Just ler him rest a bit okay...

She nods

Giyuu: By the way, Why is Nezuko with you?

Izuku: Oh... I'm her lover...

Giyuu: Okay...

Izuku: Wait just like that?!

Giyuu: Yeah...

Suddenly I felt someone was going to kill Nezuko so I blocked the sword...

???: Ara~ Ara~, why are you interfering with my job.

Izuku: Can't let anyone kill my love...

Then I feel a shiver on my spine. A second voice comes from the trees. A voice, I easily recognized...

Kanao: Izuku... What's the meaning of this?

Izuku: K-kanao... He-hey, Umm... How are things with you...

Kanao: Master Shinobu, please stop attacking her while I talk to my Lover~.

Shinobu: Okay.

Kanao: Talk!

Izuku: H-hai

I told her about what happened and what I discover about Nezuko...

Kanao: Fine... but you owe me a kiss, Mister.

Izuku: H-hai...

Shinobu: Ara ara, so you were the one who made Kanao follow her heart... And Is it really true about her walking in the sun?

Izuku: Yes...

Tanjiro: That's great Nezuko!

Nezuko: Yeah!

Crow: Summon Izuku! Summon Izuku! To the Ubuyashiki State! For a job well done in his first mission, bring Kanao Tsuyuri, Tanjiro and Nezuko Kamado as well!

Izuku: Why would they want with me... I only defeated the lower ranked demons...

Giyuu: Probably make you a Hashira...

Shinobu: That a possibility...

Izuku: But why summon Kanao, Tanjiro and Nezuko?

Shinobu: For Kanao I think to make her take the Position of the Flower Hashira... I requested to Master Kagaya...

Giyuu: For them, I think a trial...

As the sun, rose from the mountains

Izuku: The sun feels nice doesn't it Nezuko?

Nezuko:Hmmm!

Shinobu: It is true!

Giyuu: Let's go, we don't want them to wait for us...

At U.A

Nezu was in his office checking the design for Izuku's statue when a portal appeared...

Nezu: May I know who you are?

???: I'll tell you but you must call Izuku's Lovers, friends and kids here...

Nezu: Why?

???: To give information about Izuku's whereabout...

Nezu: I see you're not lying, so wait a minute.

After the call and everyone who was called arrived, Nezu asked the question...

Nezu: So who are you?

As the man reveals himself.

She ran and hugged him.
