bro really this fic is beautiful, it's been a while since I read something so nice. You managed to convey the emotions of the characters quite well, in fact you did this first and only chapter so well that you can leave it as it is without continuation and most will be satisfied.

Now speaking of the continuation, in my opinion you should leave this as it is, you do not need to continue it. Stories that only recount the events of an anime by adding only one other character to the mix, become very boring when you already know the plot thread, not to mention that when they recreate the events they rarely come out as exciting or emotional as the original. . I would advise you to leave it as it is now.

Now if you plan to continue anyway, then I would tell you to make Hanako's Story separate from Izuku's but with her own adventures (sending her to another school instead of the UA, like Shiketsu, would be a good option).

You have good thing going here

Adorable story. Needs a sequel showing more of Hanako's adventures. I especially would love to see how the Midoriya family reacts to Eri after Hinako, but I can see Hanako passing on the kindness her family showed her to Eri.

This sounds really sweet. Maybe Izuku can learn to become confident as he will be a big brother and learns to defend his sister by facing the bullies. Izuku isn't strong for himself, but for others. But someone close to him would hate seeing him hurt, and in this process I hope young Izuku changes for the better.
On a side note it would be interesting if frankestein's monster/hanako was in fact an early nomu experiment or the doctor's way of expressing grief and was found by afo for the experiments or something that ties her with the nomu's.

I love it~

A promising story, even with how little I know of the MHA universe, I can tell that having a sibling will be good for Izuku. There is also the fact that using Berserker of Black/Frankenstein's monster open mores possibilities than others Servant (Assassin of Black/Jack the Ripper for example).

With Hanako being made of six differents peoples, she could be a 'failed' prototype made before the Nouma. Plus, there is a chance that she did inherit the Quirks of these poors girls, whiche would be similar to her abilitites as a Servant. There is also the fact that Izuku and her could meet relatives of the victims during their time in UA, like Galvanism coming from Denki Kirishima family.

As for having other Servant joining UA, you'll have to look for which kind of background they would have, like Mordred being a young vigilante forced to go either at UA or in prison.

There may be some usable plots in this review, but it's your choice to use them or not. After all it's your story, not mine.

This is a seemingly good story, I would like to see were you could possibly go with it. Hope that you eventually finish this up.

All I have to say is, WRITE MORE!

if so, say izuko be mordred or astolfo
and why just frankstein? make them also adopt the lovely little jack the ripper

Its nice

D'aww. I mean really. D'aww. This has so much potential as a full series! Even taking away the fact that Fran isn't necessarily the Fran from Apocrypha, she's been adapted the BNHA universe surprisingly smoothly after all, the mere concept that Izuku gets a sister to call his own is heartwarming by itself. I mean, really. Other Fanfiction take the concept of inserting an OC or other universe sibling to the main character's family too far sometimes. Whether it'd be subverting or bashing other characters in a half assed attempt for them to, "fit in", this story made the transition very natural by making it quite clear that Hanako already made some sense lore wise. Then when you consider Izuku was ostracised to some extent because of his quirklessness, having a sibling be next to him at his low points just gives me this cuddly feeling on the inside. Do it. Make it a full series! I'll look forward to what you could come up with.

Oh, I do hope more gets added, regardless of the response. I mean, are you seriously going to be okay with letting something with this much wholesomeness end here? As Edna Mode from The Incredibles would say, "It's too much, Dahling, too much!" I definitely want to see what changes in the Midoriya household, with the addition of Hanako/Fran-chan.

I will be blunt.
MISTER YOU HAD BETTER WRITE MORE OF THIS STORY RIGHT NOW I LOVE IT SO MUCH!

More please

I’m seriously hoping this is continued, but even if it isn’t I’m still satisfied with that ending.
