The sun shines beautifully on an island far from U.A all of class 1A is doing their part sero and tokoyami closing off a beach itsuka stops a couple of creeps from perving on some girls thus making them like her instantly to her surprise and they begin to want to hang out with her shoto making ice for a slushie place while else where flames and lights form out as a crowd has been watching a battle between eri and izuku

Izuku:come on snowball show your dad what you got

Momo:GO ERI

Mina:MAKE YOUR MAMAS PROUD

Eri:ok papa here i go Dragon claw

As she emits a sharp clawed aura from her hand she rushes at izuku who flips over her dodging her attack

But she spins quickly and begins to attack over and over leaving izuku to defend pushing him back little by little

Izuku:good job snow ball you're getting much better than before

Eri:this time I'm gonna win

Izuku:hehe then let's see it

She goes in for another attack but is leg swept

Izuku:low sweep

Eri then lands on her hands as she spins and attacks

Eri:Dragon tail

This knocks izuku back as she gets some claps and cheers from the crowd which makes eri more determined to beat her father in combat as she jumps at him and begins attacking once more with him blocking each attack she had thrown at him she flips back and attacks

Eri:Flamethrower

Izuku:aura sphere

As they both launch their attacks causing a huge blast the battle is halted

Mina:sorry to stop the battle love but we're needed there's a kid missing

Izuku:duty calls

Eri:can i come papa

Izuku:of course snow ball come on

As the students begin searching for the missing kid izuku and eri finds him

Izuku:hey there are you katsuma shimano?

Katsuma:'a hero...'

Eri:papa and i heard you were separated from your sister so we cab hel-

Mahoro:TOO LATE

As they look to see a girl sliding down to them

Mahoro:Who are you what's your name

Izuku:deku

Mahoro:How could you take an entire hour to find a lost kid i think we're much better with the old heroes we had and not some inexperienced ones

Eri:hey leave my papa alone he's doing as best as he could

Mahoro:and who are you supposed to be huh kid

Eri:you aren't just looking at another kid you're looking at eri midoriya and future student of U.A and even if you're being rude it's nice to meet you

Mahoro:.....hmph whatever come on katsuma

Katsuma:o-ok

As he goes near the two of them

Katsuma:thank you both it's nice to meet you

Mahoro:come on katsuma what was the point of thanking them

Ochako:deku is everything ok

Izuku:yeah

Eri:that other girl tried to scold papa over her testing the heroes

Izuku:I'm not bothered by that eri I'm just glad he's with his sister

And so as the night came to the island the students are eating the food the kind islanders had brought to them due to the kindness and hard effort they put into their work with katsuki being put on night patrol for his lack of work and eri going out by herself for a walk as she knows her parents trusts her to handle herself all alone she notices katsuma running to the hero students as she runs over and meets up with him as he explains that they need a hero as a monster had emerged from the forest eri doesn't waste any time as she jumps up high and attacks it a dragon claw only for her to go through it and land on her face

Eri:Ow huh wait this thing is fake-

Mahoro:hey what're you doing here you're ruining the plan

Eri:plan? Wait are you faking a monster attack just to prove that my papa and the others aren't gonna come help you guys

Mahoro:and did they even come no.l they didn't did they

Eri:they're all busy trying to eat they're people too you know

Mahoro:whatever our father is better than that

Eri:hmph

Mahoro:hmph

After their little squabble with izuku and bakugo coming by with the same results and the next day

And like the movie nine and his gang attacking the harbor and causing mischief and everyone trying to evacuate and help the civilians with katsuma and mahoro being attacked by nine

Nine:there you are i found you both

Mahoro:g-GET AWAY

Nine:not the quirk I'm looking for meaning that kid there is my target

Suddenly a quick blur grabs them running through the forest

Eri:are you both ok

Mahoro:you? What're you doing

Eri:i was given permission by my moms to do a bit of rescue myself you both need to get to safety

Nine:you aren't going anywhere

Eri:'ok papa will sense my aura soon and theirs i just need to stall him for now this is my moment now' yes we are you aren't doing any bad here

Eri launches a huge blast of flames at him nine blocks it with an air shield she runs at him and attacks only to be forced back she stands back up and rushes at him

???:Dodge child

Eri:Huh

She jumps behind a tree dodging laser blasts

Eri:' what the what was that voice and why did it help me' double team

As nine begins walking through the woods a bunch of eri copies begins to jump at him and attack from all over but nine makes quick work of them grabbing eri by her head and begins to glow only for it to be a double team and she appears frim the top of the trees with a mega punch ready only for electricity to form around it as she attacks with her new move

Eri:THUNDER PUNCH

The attack slams nine down into the ground or so she thought as he defended himself and launched her into one of the trees

Eri:AGH

Nine:why don't you just quit a brat like you will never beat me overhaul made a terrible mistake not moving you earlier you test subject

As he begins to walk past her to the kids who are nearly out of the woods eri thinks about her life back then how she was left by her mother used as a guinea pig for overhaul and how nothing she ever did mattered

Overhaul:be quiet eri a kid like you doesn't understand what the importance of my tests are for

How she escaped and ran into izuku and mirio and was taken away once again

Overhaul:you made a mess of things brat you better be lucky i don't reassemble you to teach you a lesson

Mom:YOU CURSE YOU MONSTER GET AWAY FROM ME

Eri:m-mommy

Mom:STAY AWAY FROM ME YOU AREN'T MY DAUGHTER I DON'T EVEN WANNA LOOK AT YOU

Eri:I'm tired....

As her tail lights a blaze as she stands up

Eri:I'm tired of people thinking of me as a pest I Am Not A Mistake and I'm tired of being called a test subject

She turns around with a shadowed face as a gleam from her eyes shines nine who feels an intense heat turns around only to be met with eri

This slams nine into the ground as she is extremely agitated by his words and her memories and the trees begin to burn

*Charmeleon the Flame pokemon when agitated in battle it's flames becomes more intense burning the surroundings

Eri doesn't let up as she then hits him with a thunder punch and grabs his hand ending it with a flame thrower

Nine who is extremely pissed uses his hydra quirk as he grabs the young girl slamming her into a hill near the kids

Nine:That kid is Dead

As he launches a bunch of blasts at eri they all vanish as he is attacked

Izuku:AURA SPHERE

Izuki:I'm sorry I'm late snowball

As he hugs the injured girl whose horn is nearly broken off and is bleeding

Izuku:leave this to me katsuma mahoro you both are brave for giving me a good enough signal to get here thank you both now take eri safe

As izuku stands at looks at nine who is getting up

Izuku:You Messed Up Now Cuz Now I'm Mad You'll Pay
