Hey there, I am in a Demon Slayer kick over the past few days and this is my most popular story of the bunch. Let's see what happens when Izuku finally goes to train with the Hashira and how his new life style will be.

At Alderan Junior High

Izuku was with his head all raised up and he went to his teacher, giving him some pieces of papers.

''Oh Izuku is this the document?" Asked the teacher.

''It is.'' Said him.

The teacher looked at those papers and soon nodded and signed them.

''I see that everything is in check. I should have everything done by the end of the class.'' Said him.

''Well thanks sensei.'' Said Izuku.

''You really surprised me with this new. I never expected you to comeback with this.'' Said the teacher.

''Funny things happen in life.'' Said Izuku with a smile.

The teen soon went back to his seat, a lot of people looking at him a bit curious on what he just handed it over to his teacher.

However one certain person wanted to know what was the deal.

''Hey Deku! What are you doing?!'' Asked Bakugo in his usual way.

''I am asking sensei for his authorization to do the finals earlier.'' Said Izuku all calm and not afraid.

''What! Why would you wanna do that?" Asked Bakugo.

''I am going to transfer to a new place in a few weeks.'' Said Izuku all calm.

The whole class was confused about that. Transfer into a new school in the last year before High School was pretty much unheard of. Most students were confused, while Bakugo was laughing.

''Ha! So you admitted that I was right!? You want to leave this school because nobody can take your useless ass anymore?' Asked Bakugo.

''No, I got an offer to study and internship for someone.'' Said Izuku.

''Who?! Who would be stupid to hire a useless deku like you?!' Asked Bakugo.

''Mr U.'' Said Izuku all cold.

The whole class stopped talked for a moment. Everybody there knew who Mr U was. He was this mysterious billionaire that nobody has ever meet in person, but his actions were knew all across Japan. He was an incredible investor and was well known in the Economy world.

''Did you heard that?!

''Mr U! The billionaire is hirign Midoriya!''

''Man, talk about getting lucky!''

''I bet he is doing this as a campaign move.''

''No, Mr U wouldn't do something like that. He is like the Warren Buffet of this century.''

''Wow Izuku is going to hang out with a billionaire. That's awesome.''

The whole class was discussing on how Izuku could have scored something like that. Bakugo on the other hand was infuriated.

''Stop lying! There is no way a rich snob would hire you!'' Scream him.

''I am not lying! He and I had a talk and he decided to hire me! He and his team will train me and I will show you! I will be the first quirkeless hero in all of Japan!'' Said Izuku pissed.

The green haired teen soon left his classroom, Bakugo steaming with anger.

''Go ahead! I bet he will kick you out in the first three days! There is no way a weak ass like you will survive a pro hero training. You have muscle, no stamina, nothing! You are just a useless Deku and this is what you will always be!' Scream Bakugo.

Normally Izuku would just mope, and feel bad about that, but not this time. The Hashira and Ubuyashiki gave him hope and he wouldn't let Bakugo take this away from him.

''I don't care! I will work as hard as I can! If someone like you can be a hero than anyone can! This is it, Bakugo! I am leaving now…see you at the Entrance Exame!" Scream Izuku.

The green haired teen soon left his classroom. Everyone in shock to see that the super shy boy had matured a lot in the past few days. Bakugo was on the point of wanting to go in a murder spree, but he was held back. Things were surely changing.

A few days

Inko was hugging her son for the five billion time. He would be moving to Mr. U state, where he would learn, train and be there for a long time. Inko hated the idea to see her baby boy leaving, but she knew it was for the best.

''Promise to call me every 3 hours?" Asked Inko

''Yes mom.'' Said Izuku.

''Good, I am gonna miss you so much!'' Said Inko hugging her son.

''I will visit you every week that I am available. Don't worry about it.'' Said Izuku.

''Sure, but it wont be the same. Promise me to do your best.'' Said Inko.

''I will.'' Said Izuku.

The two hug one more time and one of the drivers for Mr U soon arrived to pick Izuku.

''Make some friends there.'' Said Inko.

''I will!'' Said Izuku leaving

Soon the teen was off to train to be a Hero/Demon Slayer. It would be a tough job, but he was willing to do anything to protect those he loved.

Izuku was of course super nervous, he didn't know what could happen out there and he was anxious about the idea of the type of training that the Hashira do.

''So…ready to become a demon slayer?" Asked the driver.

''Yes, I am kind of nervous at the moment.'' Said Izuku.

''Kid you shouldn't be nervous right now.'' Said the driver.

''Really?" Asked Izuku

''Demon Slaying wont happen until much later. For most of this year you will work with your hands so much that they will bleed out.'' Said the driver.

Izuku heard that and a shiver went all over his body. That idea sounded horrifying as he looks at his hands.

A few hours later.

Izuku was now wearing a training robe. Near him was Ubuyashiki with his wife, as well as the Hashira.

''Welcome to the Demon Slayer corps Izuku Midoriya.'' Said Kagaya.

''I promise to do my best!'' Said Izuku.

The Hashira just had different opinions about this kid and what he could bring to their goals.

''He is going to work until he black out.'' Said Ginyu.

''Coming from you this should be some kind of praise.'' Said Shinobu.

''What did you say?" Asked Ginyu.

''Oh nothing.'' Said Shinobu with a smile.

Then Ubuyashiki decided to see if Izuku could really have the same effort as the other demons slayers.

''We will first do the procedure. Hinaki, please bring the box.'' Said Kagaya.

''Yes father.'' Said Hinaki.

Then the little girl brought a box towards Izuku. It had some style of old Japanese language, that not even him could understand.

''This will determine if your body can handle the Breath Style. Please pick your finger with this needle.'' Said Kagya

Izuku then pinches his finger and blood started to poor.

''Ouch.'' Said him.

''Don't worry, it won't hurt for long.'' Said Shinobu.

Once a little amount of blood dropped, the Japanese writing started to glow. Much to some shock and surprise.

''Congratulation Izuku.'' Said Kagaya.

''What does this mean?" Asked him.

''This mean your body can handle and use a breath Technique. Nowadays with quirks develop this type of technique has become harder and harder. I guess since you are quirkless makes things easier for you.'' Said Kagaya.

Izuku felt a sense of pride at those words. His quirkless body was the reason that he could a Breath Technique, this was beyond exciting.

''So what now?" Asked Izuku.

''We will start your training with something easy.'' Said Shinobu.

''Oh really? What this would be?" Asked him.

''A simple run.'' Said Rengoku.

''Yes, this should be good.'' Said Uzui.

''Ok, so where is my reaching point?" Asked Izuku.

'The top of that mountain.'' Said Sanemi with his thumb pointing to the side.

Izuku saw where he was pointing at. From his distance that mountain should be at least 8 miles away. He would fait while jogging 1 mile, this was beyond insanity.

''AAAAAAAAAAAAAAH!'' Scream him in shock.

''Stop staring with an open mouth! Get to work!'' Scream Sanemi kicking Izuku to start working.

A few minutes later.

''Ok, I can do this. If they can do it so I can.'' Thought him.

Izuku started to jog and do a good pace all around. He wasn't sweating or desperate for air, he was feeling kind good for now.

Two miles later

Izuku was pretty much looking like he was about to die. He was begging for air or some sort of refreshment. He was at the point of crying in pain, he was even going down and pretty much gasping for air.

''I can't…this is too hard…I…'' Said Izuku in pain, but then someone cut him off from his speech.

''You are pathetic.'' Said the cold voice of the Water Hashira.

Izuku saw Ginyu standing near one of the trees of the forest and he felt really embarrassed by that.

''Ginyu-sama, no I was…'' Said Izuku nervous, but the Water Hashira wasn't having none of that.

''Look at you. Already giving up?! After all the encouragement that the master gave it to you?" Asked Ginyu pissed.

''No! I was…'' Said Izuku nervous but Ginyu was having none of that.

''So this it? You want them to admit they were right? To say you are nothing but a pathetic and useless deku?'' Asked Ginyu.

Izuku stopped and started to form tears in his eyes. He was right, he was about to give up on his training already.

''You want to let you mother to be eaten by demons?'' Asked Ginyu.

Izuku was now pissed and with his fist tighten. It was getting serious now.

''You want All Might and that Bakugo kid to be right? That you cant be a hero?" Asked him.

Izuku then felt a new form of energy forming inside of him. He started to run as fast as he could, pretty much leaving the Water Hashira behind.

''AAAAAAAAAAH!' Scream him at top speed.

Ginyu only saw that green haired kid run like a maniac. It would take a while, but he could at least make it until the final selection.

''I don't know if he can managed. He is so skinny that is pretty much pitfull. Who knows, I passed so maybe a screwball like him can too.'' Thoguht him.

Then he got images on his head. Of a night with another green haired kid and a scar in his forehead. What was with him bumping into these kids reently.

''He reminds me a lot of him.'' Thought him.

The water hashira soon went off to be on the Headquarters. He need it to be present if a mission or demon attack would to occur. As a Hashira he was pretty much one of the busiest people around in the Demon Slayer Headquarters.

So this is it, I hope you all enjoy this chapter and it was a blast to make. Next ones will be Izuku training and figuring out what is his breathing. Remember you all, it isn't Water because that's already Tanjiro. Hope you all are good and see you all later.
