Ch. 6 Enter Eri an orphan with the Rewind quirk

After Izuku and crew talked to Tenya and Ochcako the school day ends with Izuku, Ochcako, and Tenya walked to the train station.

The three heard some noises from a dark and spooky alley.

"What was that?" ask Ochcako

"I don't know. But let's check it out!" said Izuku who ran into the alley.

"Midoriya wait!" Tenya yelled.

As Izuku ran deeper and deeper into the alley he found a little girl with white hair.

"Hey, you okay?" ask Izuku who ask the child before the child replied a man came out.

"Oh, thank God! Eri you're okay!" said the suspicious man

"Oh? Is she your child?" ask Ochcako as she caught up to Izuku.

"Yes, good sir. Is she your daughter?" ask Tenya who also caught up

"Well...Um Yes I am." said the man.

"He's...not...my...daddy." said the little girl as she whispered those words to Izuku which scared him.

"If what Eri said is true then I got to do something!" Izuku thought

"Uhh...We should get her to a doctor." said Izuku

"N-no thanks my boss is a doctor." said the man

"Are you sure sir? She looks like she hasn't eaten anything." said Ochcako

"Yes, my friend is right good sir if she has injuries, we must contact proper authority." said Tenya but made the man mad.

"You WILL NOT! CALL ANYONE!" yelled the man as he attacks with his quirk which was lighting base.

Izuku intercepted with a Crossfire attack

"Guys! Protect Eri! Take this! Firefly and Firery Doll!" Izuku yelled as tiny green balls come out of Izuku's hands and exploded around the stranger

"YOU BRAT! I DON'T CARE IF I HURT THE GIRL THE BOSS WILL PUT HER BACK TO TOGETHER LIKE HE ALWAYS HAS!" yelled the stranger.

But then a blonde-haired man wearing a suit came out of nowhere and kicked him

"Mutton Shot!" yelled the man

"Who are you?! / Wow awesome! /Scary!" yelled Tenya, Ochcako, and Eri

"Sanji!" yelled Izuku

"WAIT?! "Black Leg" Sanji Vinsmokes?! Cook of the Straw hats Pirates….I out a here!" the stranger trembling in fear and tried to run away.

"SMASH!" Yelled All Might as he stopped the stranger from escaping

"ALL Might!" yelled the U.A. Students

"Are you kids okay?" asked All might

"Yeah/ Yes, Sir! / We're okay!" Izuku, Tenya, and Ochcako replied.

"Are you okay Mademoiselle?" Sanji said with a gentleman tone.

"Uh, yes!" Ochcako exclaims.

"Sanji should I tell the wife you're hitting on underage girls or should I call on "them" Izuku threaten Sanji.

"Oh, is this girl your GIRLFRIEND?" asked Sanji as Izuku and Ochcako blushed

"NO! SHE/HE NOT MY BOY/GIRLFRIEND!" yelled Izuku and Ochcako as they blushed

"Ah, young love. Now let's bring this guy to the police station." Sanji stated as he dragged the guy's body to the police station.

At the police station

"So, who's this guy? Old friend." asked All Might

"Apparently he just a small-time thug and knows almost nothing. Yagi." said Naomasa Tsukauchi

"So, who is the girl?" asked All Might

"Her name is Eri but there are no official records of her it's like she doesn't exist," Naomasa stated

"What?" All Might questioned

". And we got more problems the girl is the granddaughter of the former leader of the Eight Precepts of Death. But she has taken a liking to Izuku and Ochcako as her "parents" and identify her quirk as an age affecting one called "Rewind". To a point that the target didn't exist." Naomasa stated.

"What are we going to do Detective? Where on earth are we going to find a person who can handle a permeant age affecting quirk." All Might state.

"Izuku's mom can teach her," Sanji stated.

"Are you sure? Vinsmokes." asked All Might

"Hey! Do you know whose mom Izuku is she is Jewelry Bonney the "Glutton" and the one who ate the age-age fruit, if you need a trainer, I bet she would train her." Sanji stated

"Hmm...that actually could work and since Jewelry Bonney lives within Straw hat and the Four Emperor Alliance territory Eri would be safe," Naomasa stated

"So, it's decided then I'm going make some calls," Sanji said as he pulled out a snail phone.

"purupurupuru...purupurupuru... ...click!" the snail ring

"Are right who dares to call Yonko Achilles when he's sleeping!?" Achilles yelled on the other line

"Who is it dear?" a sleepy wife asked

"It's Sanji! VIVI CHAN!" he replied

"Sanji?! Nice to hear from you again. How are you? And on a side note, you're dead meat if you flirt on my wife again." Achilles said

"I'm fine though Izuku protected a little girl from a minion and I need you to find any information on the guy and who he works for," Sanji asked

"I'll get right on it just send the info via transponder snail with a white one attached to it! Or Else someone shall walk the plank with the black spot HAHAHA! kaa...chink!" Achilles ended the call and the snail went back to sleep.

Sanji called Jewelry and got a replied then left to go to his family.

Meanwhile in another room

"So, what do you think will happen to Eri, Midoryia san?" Tenya asked

"Yeah, Eri seems so scared when the police took her" Ochcako stated

"Maybe, they're deciding who will take care of her" Izuku stated

"That's correct young Midoriya!" All Might replied as he entered the room.

"It's All Might!" Tenya and Ochcako yelled

"What do you mean?" Izuku asked

"We been talking about who will take care of her and train her, then your "uncle" gave us an idea you will take care of Eri while your mother will train her to use her quirk!" All Might explain with gusto

"NO WAY!"Izuku, Ochcako, and Tenya yelled

"Did you ask my mother yet?" Izuku asked

"Yes, we did by via Transponder snail by your uncle and she said yes!" All Might replied as Eri came out.

"Mommy! Daddy!" Eri jumped out and knocked over both Izuku and Ochcako while they were blushing.

"Umm...All Might why did Eri called Izuku "dad" and Ochcako "mom"?" Tenya asked

"It's because that Izuku is the first boy that Eri met that protected her while Ochcako is the first girl to care for her also." All Might explained. Izuku recovered from his shock

"Umm...does that means we can go home?" asked Izuku

"Yes, though you and Ochcako must go together since she sees you two as her "parents" Naomasa explains.

One an hour later Tenya went home while Izuku, Ochcako, and Eri made it to Izuku's home.

"We're finally home. Oh, Ochcako, Eri my family can get insane once you enter just be careful." Izuku said with worried looks.

"Mom I'm home!" Izuku said.

"Oh, dear, you're late. Why are you late?" as Jewelry Bonney looked at Izuku there was a girl with brown hair and a child with white hair and a horn.

"Umm...why is there a strange girl in my house and why is there a little girl?" his mother asked

Izuku explained it to his mom and she was both proud and mad at Izuku that she hit Izuku on the head with a frying pan and then hugged Izuku.

"Oh!? If you're the "dad" and Ochcako is the "mom", does that mean? Are you Izuku's girlfriend by any chance?" Jewelry asked

Both blushed and before Ochcako replied

BOOOMM!

Out of nowhere two kids were fighting each other one is a black hair kid holding a pipe while the other is a blonde with a toy spear.

"Take THIS! Blue flame/ Tremor infusion... BLAST!/ SLASH!" both the kids yelled as they were about to clash Rouge hit both in the heads.

"STOP YOU MORONS WE HAVE GUESTS! I'm sorry for my idiot brothers' behavior" Rouge said as she bowed.

As Roger looked up, he saw a girl behind Izuku's leg.

"Umm... hello, I'm Roger what's your name." Roger asks

"I'm E-Eri" Eri replied but was stilled scared

"Looks like there is fresh meat! That means I get to pick on Roger more!" Edward sneered.

"YOU WANT A FIGHT?! LET'S GO!!" Roger yelled and Edward responded as a fight cloud covered them. While Rouge groan at their fighting.

"What are they fighting for this time?" ask Izuku.

"Today is for a stupid juice box again!" Rouge said with anger.

"All right, ENOUGH!!" Jewelry yelled with stopped the two fightings.

"We're sorry, mommy." Roger/Edward said at the same time

"So, who's hungry?" Izuku asks to break the ice.

During dinner with Ochcako was fine they discuss how they met during the exam and how she discovered Izuku's secret. But she has one more question.

"So, umm...how did Roger, Rouge, and Edward are 6 years old? Because didn't Ace died 10 years ago, if you don't mind answering." Ochcako asked

"Well 10 years ago after Ace died, I found out I was pregnant. So, after Izuku came home we went into hiding I held those little munchkins for 4 years." Jewelry said as Ochcako interrupted.

"Wait? FOUR YEARS?! But how?!" Ochcako asked

"Well I used my devil fruit powers to change their embryos' age and after the hunt for Izuku finally ended I gave birth within Strawhat territories and that's their origin story." Jewelry explained

"Cool!" Eri and Ochcako yelled with stars in their eyes

"Deku! Your life is amazingly crazy!" Ochcako said

"Thanks, Ochcako-chan let's finish our food and rest for school tomorrow although there was an attack you might want to contact your parents to stay here due to reasons." Izuku explained

Later Ochcako called her parents to tell them what happens and what's the situation and they agree to it.

"Good night mama. Good night papa...ZZZZZZ" Eri said then fell asleep

"Um, Deku." Ochcako getting Izuku's attention

"Yeah, Ochcako?" Izuku whispered

"Um, I really wanted to thank you what happens at Marineford island 10 years and I wanted to do one thing." Ochcako blushed

"Oh? And what's that?" as Izuku ask her Ochcako kissed Izuku on the lips while in the background Izuku's mom and his little siblings recorded the entire thing with devious smiles.

When they broke the kiss Izuku was so embarrassed that steam came out of his ears.

"Umm...Uhh..." Izuku confused and embarrassed

"After I woke up after the battle, I wanted to thank you, but you disappeared after I was knock out by your haki. I wanted to find you, but it was rumored that you were dead. Until at the exams the fire in your eyes reminded what I saw in your eyes 10 years ago." Ochcako tears up and cries.

"It's okay, Ochcako-chan. Hah, you 10 years ago I actually developed a crush on you when I saved you. Even if it was just a split second before I went unconscious. Heh, you know destiny really does has a way to bring people together." Izuku stated as he smiles and had some tears in his eyes.

"Umm...Deku do you mind me being your girlfriend?" Ochcaok blushed

"Sure! In fact, I was going to ask you the same thing but with an actual date." Izuku smiles

"Sure, Deku a date it is. Good night...ZZZZZ" Ochcako said as she fell asleep

Izuku fell asleep as well. When Izuku fell asleep his mom and little silbings had plans to spy and/or mess with them during their date.
