Hi there, thank you all for the nice messages and the support for this fic. I really want this one to take off and how impactful the world of My Hero would be if the stuff from One Punch man existed, I mean after the crap Empty Void could do then I would say most of the heroes of Japan that don't have plot armor would be dead. Hey, lets see the life of the Midoriya family now that their baby brother is born, yeah it will take a while for Izuku get to the hero school, I guess around 5 or 6 chapters after this.
Also, I wanted to give my opinion in the fanfic on the Strongest Hero Deku story, which is one of the top My Hero x One Punch stories. I don't buy it, like I can believe Izuku getting all the powers of One For All is strong but not as strong to get S Class position 1, even if you take off Blast and Saitama out of this world there are a ton of other people stronger than him. Sorry for this, now back to the main story.
At the Midoriya Household.
It was the middle of the night, and the family was all sleeping in their room, when suddenly the newborn Izuku started to cry a lot.
"AAAAAAAH!' Scream the baby.
"I got this.'' Said Tatsumaki getting out of the bed all tired and going to take care of her baby brother.
The older sister went to Izuku cradle and hold him to see if he was ok.
"For a baby you've got some lungs.'' Said the girl all tired.
Tatsuki could sense that Izuku had a nightmare, this was very common, and she had seen her mom make sure Fubuki was also calm when she had something similar to this when she was a baby also. The elder sister rocked the baby back and forth, making sure he was peaceful and happy.
"Don't worry Izuku, I am here.'' Said her.
The nice movements and humming music that she was making made Izuku fall asleep in record time, Tatsu then put her baby brother back on the cradle all happy that he was all fine.
"There.'' Said her kissing him in the head.
Tatsu then gave her baby brother one last look before going back to her room.
"Good night Izuku.'' Said her.
Tatsumaki closed the door quietly as she saw her mom standing near her room.
"Is Izuku ok?'' Asked Inko.
"Yes mom, I put him back to sleep. Now go back to bed.'' Said Tatsumaki.
"Oh thank you Tatsu, you're such a good daughter.'' Said Inko.
This was a norm around the Midoriya house, Tatsumaki was taking care of her siblings on her off time from hero school and also to give Inko some time to relax, after all rising 3 kids by herself is not an easy job.
A few days later
It was a nice sunny day, and it was also a weekend, Inko decided to go out and have a walk around the park with her children.
"Girls, put your shoes we are leaving in a few minutes.'' Said Inko.
"Yes mom!'' Said the two.
The girls went to check if Izuku was ok and if he had his blanket and a nice diaper, but he was still looking a little upset, that is until Tatsu brough his All Might plushy.
"Here Izuku.'' Said Tatsumaki.
"Yaaaaha.'' Said the baby all happy.
The girls bought that toy in a shop down the street for a few bucks, it turned out to become Izuku favorite toy.
"He really likes All Might.'' Said Tatsumaki all happy.
"I think he is going to love heroes even more when he grows up.'' Said Fubuki.
"Ok girls, I am ready let's go.'' Said Inko.
The family left as Inko stroll Izuku on his baby cart
At the park
The family was having a nice day, having some sun and showing the park to the newborn who appeared to be enjoying.
"Its nice to have some quiet time like this.'' Said Inko.
"Yes mom, I've been pretty busy lately with my Pro Hero training but with my talent I will be out of school in no time.'' Said Tatsumaki with a smirk.
"Tatsu, that's not nice. I want you to graduate from high school like a regular kid, be hero or not.'' Said inko.
"Oh don't worry mom, against my classmates I am no question the strongest person on my entire year. I am pretty much just killing time until the sports Festival.'' Said Tatsu a bit arrogant like always.
"Big sis, what about the pro heroes of today? They are pretty strong and then more appear every year.'' Said Fubuki worried.
"I don't worry about this, all the upcoming heroes are such weaklings. I can kick their ass in no time and come back for more, I have nothing to worry.'' Said Tatsumaki with just a little bit of a smirk.
"Oh look who is there, Mistuki!'' Said Inko seeing another mom with a baby cart.
The two saw her, she was a nice-looking woman around late 20s like their mother, she had spiked blonde hair and a nice skin. She and Inko were friends for a long time ever since the girl's mother introduced her friend Masura to Mitsuki and that would end up in a marriage and finally a baby.
"Mitsuki-chan.' Said Inko.
"Inko-chan, Tatsu-chan, Fubuki-chan!'' Said Mitsuki.
"Hi aunt Mitsuki!'' Said the two.
The two moms stopped their baby carts and started to hug each other.
"So how is motherhood going for you?'' Asked Inko.
"We have some rough parts here and there but overall is a wonderful experience. However, I have to admit that one is enough for us, kudos to you about raising three.'' Said Mitsuki.
"Its not easy being a mother, but I can tell you are doing a good job in raising your osn.'' Said Tatsu seeing that Mitsuki didn't had a single dark circle in her eyes.
"Thanks dear and this must be little Izuku.'' Said Mitsuki seeing the green hair baby.
"He is adorable isn't it?'' Asked Fubuki excited to talk about her baby brother.
"He is Inko-chan knows how to make the prettiest of babies.'' Said Mitsuki.
"Oh thank you.'' Said Inko blushing.
"What about your aunty?" Asked Tastu.
"I've been pretty busy with mine too.'' Said Mitsukii
"Well, I hope they can grow up to be great friends.'' Said Fubuki.
"Thanks, so aren't you going to introduce your little one?'' Asked Inko.
"Oh yes, Midoriya's this is my little son Katsuki. Say hi Katsuki.'' Said Mitsuki showing off her baby son.
The family saw Mitsuki son and while inko just saw a cute baby, the girls saw how he was acting like he was totally pissed off to be there.
"He looks angry.'' Said Fubuki a bit scared.
"Like he is possessed.'' Said Tatsumaki.
"Tatsu!'' Said Inko embarrassed.
"What?'' Asked the older sister not carrying.
"it's common, I was also like this when I was a baby. Come on Katsuki, say hi to your new friend.'' Said Mitsuki.
The baby then raised his arm and showed of his middle finger to the other baby, much to the shocked of everyone.
"Did he just flip my brother!'' Said Tatsumaki all pissed.
"Katsuki no!'' Scream Mitsuki embaresed.
"Yaaah!'' Said Izuku also copying the other baby smiling thinking this was a good thing.
"Izuku!'' Scream Inko in shock.
"How did he learn that so fast!'' Said Fubuki in shock.
"That kid is a demon from hell!'' Scream Tatsu looking at Katsuki pissed.
"I'm so sorry for this, I better go home. When we get there you are going to learn something Katsuki!'' Said Mitsuki pissed at her baby as he started to scream.
"AAAAAH!'' Scream the baby.
The Midoriya family felt a little nervous as Izuku kept the middle finger position and other people were looking at that scene, wondering what was going on.
"Is he still with his arm up?'' Asked Inko.
"Yes!'' Said the two girls nervous.
"Let's go girls!'' Scream Inko going a little bit faster.
The family tried to get out of the park as fast as they could, Tatsumaki already disliking that kid Katsuki.
"That baby is going to pay!'' Said Tatsumaki all pissed.
"Tatsumaki, you're glowing!'' Said Fubuki worried.
The family went a little bit faster so they could get home as soon as they could.
A little later
The family finally arrived at their home and Inko put Izuku to sleep, hoping that he would stop the middle finger movement. Meanwhile Tatsumaki was fuming in anger while Fubuki worries that her sister would go berserk.
"That little brat is going to pay!'' Said Tatsu.
"Big sister he is just a baby!'' Said Fubuki.
"What, he might be a bully! You know what happens when I see my little siblings get bullied!'' Said Tatsu all pissed.
"Please, I don't want our brother to go through what you did to me!'' Said Fubuki.
The poor girl had to move from school because once Tatsumaki found out she was getting mocked and bullied she went there and tossed the bullies to the other side the state. Needless to say it was a embarrassment event and apologies were made.
Inko soon arrived and went to calm her older children.
"None is going to do any harsh things; I don't want any harsh treatment to Mitsuki child. She is my friend and the one who will decide if they will be friends with little Katsuki will be Izuku himself.'' Said Inko to Tatsu who calm down.
"Sorry mama.'' Said Tatsu.
"Good girl, now are you excited for the UA sports festival?'' Asked Inko.
"Well, I would if I was having difficulty in using my quirk, but I can already lift a tank so what I would be worried about?'' Asked Tatsumaki.
"Are you sure? There might be someone in your year that might bring a challenge to you.'' Said Inko hoping Tatsu would have some sympathy.
"Please mom, I am the best in what I do and soon Japan would know.'' Said Tatsumaki with a smirk.
Tatsumaki Midoriya was sometimes a bratty and temperamental person, Inko sometimes think she reminds her of Mitsuki. The mother thinks because of her imprisonment while young Tatsu develop this idea of being on the top, so if she had to be aggressive, she had to be. Inko tried to make sure Tatsu apologized for humiliating people or not go overboard, sometimes it worked and sometimes it didn't, still she was never insulted by her own daughter and was very proud of her achievements as a hero students.
A few weeks later
The UA Sports festival arrived and it was like always a huge celebration to see the next generation of heroes showing off their powers.
After a long day of trials, hard work, tactical plans and battles one person won the festival in the end.
"And we have a champion! The winner of this year, first year UA Sports Festival First Years is…Tatsumaki Midoriya!' Scream the announcer.
Tatsumaki just looked bored as her opponent is being carried away to the infirmary.
"Is that all?'' Asked her with a smirk.
The stadium goes nuts as everyone started to celebrate the now victorious esper hero student, who many saw going many places.
At the Midoriya household
Inko decided to watch the event on TV, so Izuku wouldn't be scared by the stadium or the fireworks. They just saw Tatsumaki win the sports festival and be declared the first year ultimate winner.
"Yeah! Tatsumaki did it!'' Said Fubuki all happy.
"That's my baby!'' Said Inko crying as she saw Tatsu as the champion.
"Taaa!''Said baby izuku seeing his sister on TV.
"That's right Izuku, Taaa won the sports festival. Isn't this great?'' Asked Inko.
While Inko played with Izuku the other Midoriya saw her big sibling on TV, showing off their power and being proclaimed an upcoming sensation.
"She is amazing.'' Thought Fubuki.
The young girl knew her quirk hasn't fully developed, she could do a good amount of psychic powers that were better than her mother, but she was no near the starting point that her sister was. Fubuki could bend a spoon with no problem, Tatsumaki could bend 1000 spoons in just a second. The young girl has been having a lot of thoughts recently and she had an idea.
"Maybe I can be like big sis someday.'' Thought her.
So yes, we have a nice chapter about the Midoriya family today. Not the biggest one, but hey it's a nice chapter and we see Tatsumaki win the UA sports festival, so we can add that for this world lore and how it will be worked out. I need to establish some things before going out, but I am having fun so far with this.
I need to give more details on why Tatsu is still a bratty person even tough she was raised properly and how is Fubuki going to become the way she is at the moment.
Fubuki has an inferiority complexity, something that Izuku will also inherit so we can see how they want to be on top when they have a sibling that is on league or to be honest above All Might.
Next chapter will be a explanation about the Hero Association and the HPSC and how heroes in this society work when going to one place or another. Thank you all.
