Hey there, since Its been almost a year since I updated this fic I think a double chapter should be good for everyone. This is kind of a small one because its mostly about Izuku birth and Tatsumaki promise. Unlike canon, Tatsumaki is more affectious to her family, she will be a bit brash to her siblings but its on a protective level, because unlike canon she grew up with a happy family and attention, I decided to keep her brashy attitude because she is naturally like this, the idea of even if she was on a different setting she would be like this, plus its fun to write this. Well lets get this done.

9 Months later

At the Streets of Musutafu

Tatsumaki was flying around the street of the city while also lifting the 9 year old Fubuki, the small girl was scared while Tatsumaki (that still looked like a 10 year old) had a look of determination. Her mother had got into labor and she wanted to be there for her. Inko tried to get the girls be with her friend Mitsuki, but Tatsumaki escaped. At the moment the green haired psychic was flying at top speed in direction of the hospital, not carrying if she hits someone.

''Come on! Get out off my way!'' Scream Tatsumaki dodging a car.

''Big sis! Careful we could have been hit.'' Said Fubuki scared out of her mind.

''We need to get to the hospital now, mom is in pain and we need to be there for her.'' Said Tatsumaki.

''But isn't she with doctors?'' Asked Fubuki.

''Oh please Fubuki, I am not letting some no name doctors take care of our mother. I want to see them with my own eyes.'' Said Tatsumaki.

The girls continue to fly with no problem; however a cop stops them in their tracks. Fubuki was all nervous but Tatsumaki wasn't nervous at all.

''Hey! What are you two doing?!'' Asked the cop.

''Uh.'' Said Fubuki with fear.

'You two little kids know that is forbidden to use quirks outside! Plus flying is very dangerous.'' Said

''Little kid! I am 14!'' Scream Tatsumaki pissed, she hated being called Little kid, even though she wasn't too tall and her mood sometimes can be a little bit bratty.

''What! Lolita!'' Scream the cop.

''Please sir, our mom is in labor. We just wanted to be at the hospital.'' Said Fubuki all sweet.

''Yeah, now let us go through.'' Said Tatsumaki still all serious.

The cop wanted to give that girl a lesson, but he could tell she was worried about her mother, so he decided to let that pass.

''Sure, but don't do this all the time. Be careful around traffic.'' Said the cop.

''thanks.'' Said Fubuki.

Tatsumaki just give a ``huff`` and kept flying away at top speed. The cop just clean the sweat on his forehead and commented about the older girl.

''Man, that girl is going to give people trouble in the future.'' Said the cop.

At the Hospital

The place as at full peace, no problems or anything to cause any sort of chaos. Until Tatsumaki came at full force still lifting Fubuki with her quirk. The entire staff was in shock from that and wonder if something horrible happened.

BAM

''Uh!'' Scream a nurse in shock.

''Inko Midoriya, where is she?!'' Asked Tatsumaki all serious still hovering over the nurse.

''Who are you!?'' Asked the nurse.

''Tatsumaki Midoriya, her older daughter. I came with my little sister, tell me where is she.'' Said Tatsumaki still wanting answers.

''Oh miss Midoriya, she has just entered in labor.'' Said the nurse looking at her computer making the two girls be in shock.

''How long has been?'' Asked Tatsu.

''About an hour, the doctors are helping her right this moment.'' Said the nurse.

''Good now where is the room for…'' Said Tatsumaki and the nurse stopped her.

''No teenagers or young kids are allowed in the back. Are your father present with you two?'' Asked the nurse.

Tatsumaki just looked annoyed at that as Fubuki answered for the nurse.

''Papa isn't here, he works in U.S.'' Said Fubuki.

''Apparently the birth of his son is not important enough. Couldn't figure out a way to fly back?! What a low.'' Said Tatsumaki all pissed.

''don't say that Tatsu, papa works hard for us.'' Said Fubuki.

''Miss, I understand your frustration, but you cannot go on the back, the doctors are already in procedure. You can wait in the waiting room with your sister as long as you want, but you need to calm down and stop using your quirk as this might cause troubles for patients.'' Said the nurse.

Tatsumaki heard that and was ready to give some argument, Fubuki hold her older sister hand and had a look of ``please`` in her face. The chibi teen took a deep breath and stopped glowing for once.

''Fine, I am calm. We will be here waiting, but anything informs us.'' Said Tatsumaki.

''Sure, you will find the Wi-Fi password in the walls and there is a restaurant nearby if you get hungry.'' Said the nurse.

''Thanks miss.'' Said Fubuki all sweet.

The two sisters went to the waiting room and just see how their mother would be a few hours later. Tatsumaki brought some headphones, one for her and one for Fubuki so they wouldn't cause any sort of noise in the area.

A few hours later

Tatsumaki was still awaken as the sun was rising up, Fubuki was sleeping on her sister lap taking a rest after a long night. Before Tatsumaki could start a scene again the nurse from early appeared.

''Miss Midoriya.'' Said the nurse.

''uh?'' Asked Tatsumaki seeing the nurse.

''Your mother is out of the room.'' Said the nurse.

''And how did the labor went?'' Asked Tatsumaki.

''The procediment was a success, your little brother is a healthy baby.'' Said the nurse.

Upon hearing that Tatsumaki started to spark with joy, her mom was ok and her baby brother was all normal.

''Fubuki wake up! Mom got out! We can see her.'' Said Tatsu waking the little girl.

''Our baby brother is here?'' Asked Fubuki with a smile.

''Yes!'' Said Tatsumaki.

''Would like to see them?'' Asked the nurse.

''Yeah!'' Said the two.

A few minutes later

Inko Midoriya was taking a good look at her third child and the first born male, she would love that kid nonstop, now she was waiting for her older children to gather around. She knew her daughters would love him. Speaking of the devil, the two girls arrived at her room.

''Mom!'' Said the two.

''Girls be quiet, he is sleeping.'' Said Inko

''how are you doing?'' Asked Fubuki hugging her mother alongside Tatsuki.

''Tired but this is just my third child.'' Said Inko with a little joke.

''Is that him?'' Asked Tatsumaki excited as Inko just smile holding the baby.

''Tastumaki, Fubuki meet Izuku.'' Said Inko showing the little baby face.

The two looked at their baby brother, he had the green hair like all of them, the freckles of their father and looked so cute.

''He is so tiny.'' Said Fubuki.

''Yes, but he will grow one day into a beautiful man.'' Said Inko being careful around the newborn.

Tatsumaki saw her baby brother and just smile with joy, it was the samee sensation when Fubuki was borned.

''He is so cute.'' Said Tatsumaki.

''Yes, but I want you two to promise me something.'' Said Inko.

'''Uh?'' Asked the two girls.

''You two have to promise me that you will take care of him if something happens. As the older siblings you two have to make sure that Izuku is safe, in this world we don't know what will happen.'' Said Inko all serious.

The two girls were a bit nervous, but Tatsumaki wasn't going to let that slow her down. She was going to be the best hero in all of Japan, to make sure that her family wouldn't be attacked like she did when she was a kid. If someone would come after Izuku she would pretty much just destroy them and their life's.

''I promise.'' Said Tatsumaki all serious.

''Me too mom!'' Said Fubuki.

The mother just smiled at her girls, she raised them very well considering she is still young.

''I am glad of that. Would you like to hold him Tatsu?'' Asked Inko.

''Yes mom.'' Said Tatsumaki holding her baby brother.

Tatsu saw Izuku opening his eyes towards her, he had a little smile and showing his no teeth mouth. Tatsu just smile at her cute baby brother.

''I promise Izuku, I will love you and I will make sure you are ok. I will be a good big sister.'' Said Tatsu making a promise as she touches little Izuku forehead.

So yes, this chapter is a small one and very similar to the first chapter of Tornado Siblings. Yes, that fic is better structured but considering the author gave up on that story I am that you all have left. I also like moments like this, showing Tatsumaki soft size, because if she wasn't raised like she was in canon she wouldn't be that bratty, she is still going to be one in the future but not at the maximum as in canon.

Also just to let people know ahead, there are two different hero associations groups in this world. There is the MHA one the Hero Public Safety Commission and then there is the One Punch one which is the Hero Association. I mean I know Horikoshi didn't wanted to be bother to create different Hero Leagues that employes heroes, that would be too difficult to write everything, but if One can do it at his Webcomic than he should have done at least some kind of idea.

Well, we are getting places in this stories. I want to write more chapters in this one and not Omakes. I hope you all enjoyed and have a good day.
