Izuku's P.O.V

???: I'll be sending you to the world full of demons, you must kill the Demon King, Muzan, after you finished him I'll send you back...

Izuku:Okay, I will

???: I'll give you all the knowledge you need, in order to live in this world and I will also give this...

???: That sword on your waste is a nichirin sword or the color changing sword, it will help you in slaying demons, and that haori is something you will wear in that world, it might be ordinary but I made sure that it's indestructible... And I changed your name to Midoriya Izuku and also change your DNA .

Izuku: Thank you, I appreciate your kindness to me.

???: You must first join the final selection for the Demon Slayers, you already know this so, I will not explain more.

Izuku: Yes, you gave me all the knowledge I'll need to live in the other world, but I must go now, so I can finish it fast...

???: Hahaha, no need to hurry my child... Get stronger and find friends and maybe love... In your way, I know what you went through and you have you lovers waiting but you must still enjoy your life in this world, and if you do find love, you make take her or them to your world.

Izuku: I understand.

???: One last thing when you finished your final selection, I will be sending you a gift.

And after that, I woke up in a forest, I walked until I saw a road and decided to follow it, while walking I saw a guy with a mask on the side of his face wearing a blue haori, with a katana. I decided to ask him for directions

Izuku: Um... Can I ask for directions?

???: Sure.

Izuku: Do you know where the final selection will happen?

???: Ah, so your going too?

Izuku: Yes

Tanjiro: Great, follow me, by the way,I'm Kamado Tanjiro, nice to meet you uh...

Izuku: Oh! Midoriya Izuku, you can just call me Izuku.

Tanjiro: Then call me Tanjiro

Izuku: So, Tanjiro what's your breathing style?

Tanjiro: Oh... It's Water, it was so hard to learn I receive so many blows from my master...

Izuku: Eh... So did you learn the Total Concentration Breathing?

Tanjiro: The what what?

Izuku: It's... Ah... How do I say this? Ah! increases the user's capabilities beyond that of a normal human through advanced forms. This expands the user's lung capacity. This allows oxygen to reach every cell in the user's body, increasing their blood circulation and heart rate.

Tanjiro: Oh! Can you teach me that?

Izuku: Sure! After the Selection

Tanjiro: So Izuku since we're talking about my breathing style, it's only fair to say your's right?

Izuku: Oh of course, mine is Nature Breathing, it's breathing that is made from breathing styles that connects with nature, like water, fire, ground, wind and more.

Tanjiro: Wow! So cool! That means your strong right!?

Izuku: Well not really even though, I know that breathing style means I'm strong it only means that I have a power to fight and protect that's all that matter.

We walked until we saw those beautiful flowers, and we reached the top of the mountain and saw all of the participants...

among them is a beautiful girl with pony-tailed hair at the right side , she was quiet, I decided to talk to her...

Izuku: Hello

She tossed the coin and it landed on heads.

???: Hi...

Izuku: My name is Midoriya Izuku, do you decide what you do by the coin?

She tossed it again, and landed to heads again.

Kanao: I'm Tsuyuri Kanao..., and yes...

Izuku:Then let me borrow it for a moment

Kanao*tossed landed on heads*: Okay...

Izuku: Thanks, Now if it's heads you will let your heart decided on what you must do!

I tossed it until, it landed on my hand and walked to wards Kanao to show her.

Izuku:It's... Heads! Yes! Here so a deal is a deal you will listen to your heart from now on.

I saw her looking at the coin with a sad expression...

Izuku: You can keep it if it's important to you, you don't have to throw it.

Kanao: Really?...

As she was trying to decide on her own, and turning a little red?

Izuku: Yeah... And good luck!

I returned to Tanjiro... And listen to the instructions

Timeskip

We walked towards the forest we killed every demon we encounter, I also learned about his sister's problem and told him I'll help him find a cure and kill Muzan.

We also fought a demon that was killing every student of Tanjiro's master... And in the end Tanjiro killed him to avenge his fallen seniors...

On the last day we saw that there were only 5 of us remaining, the twins told us about our messengers, three crows landed on, Tanjiro, Kanao, and Bakugo look-a-like guy and a sparrow... To the yellow haired guy... and I was waiting for my crow when a Eagle landed on my shoulder and it talked...

After Tanjiro and the others chose their ore and I requested to just use my sword, I was sorry for the ones who didn't return, until Kanao walked towards me...

Kanao: I see you made it... Congrats... Izuku...

Izuku: Thanks Kanao, Congrats to you too...

Kanao: Thanks...

???: Oi, you lucky bastard!

Izuku: Who? Me?

???: Yeah, you how can you be so lucky getting a girl in the Final Selection! Huh!?

Izuku*disgusted expression*: What?

:Don't look at me like that!, I'm Agatsuma Zenitsu, and I'll defeat you one day for finding a girl in the Selection.

Izuku: you're a disgrace to human kind

Zenitsu: What did you say!?

He left and Kanao talked again.

Kanao: Um... Can... I ask something?

She said while blushing.

Izuku: Sure

Kanao: You see I was feeling something when the selection started and I decided to ask the other participants on what it is... And they said I'm in love so, um... Can you be my boyfriend?

Izuku: I can'-

Tanjiro: He would love, too. He wont stop thinking of you during the exams.

Tanjiro said while smirking.

Izuku:Damn you Tanjiro! I was gonna decline because of my lovers, I told you that! Damn you!

Kanao:Really!?

She asked looking at me for confirmation, while smiling

Izuku:Damn that's to much, *sigh* I can't decline anymore... She too beautiful... Y-yeah... So I guess I'm your boyfriend Kanao...

She hugged me and kissed me on the lips, after a minute she backed away smiling.

Kanao: I hope we see each other sooner.

Izuku: I'll visit you after a few mission.

Kanao: Looking forward to it and I live in the Butterfly Mansion.

Izuku: I'll just ask direction to where it is... Bye!

As she left and returned home and I was going to but I remembered one thing...

Izuku:WHERE WILL I STAY!?

Tanjiro: Don't you have a home?

Izuku: Really I just told you I'm from another world and you think I have a home here...

Tanjiro: Right, it just hard to believe... You can just come with me in my master's house, he wont question it... Plus I have a sister that you might want to add to your Harem, Oh great Harem King~

Izuku: Damn you Tanjiro! I shouldn't have told you about my lovers!

Tanjiro: Hahahaha, come on let's go so you can meet her.

Izuku:You're really pushing her to me aren't you...

Tanjiro: Yes, I want a brother-in-law.

This guy is impossible...
