A/N: Usually I would have a second chapter ready to go but I have been busy so here some fluffy to tie you over... and a kind of preview to a subplot you will see in the next chapter.
Sometimes people seem to forget what Izuku has been through, sometimes it seems that they don't care, but he was with someone who had been with him throughout it all. Now… now they shared something that would turn out to be unbreakable, a bond with someone who they will do absolutely anything for. This is a story from a month and a half ago when some wounds were fresh, and both were in for a new experience, a new twist to the dangers of a hero and his agent, a child that needed them both. "Eri Midoriya... Eri Midoriya, the doctor will see you now."
Midoriya... Midoriya was not right, at least not yet. Izuku had rescued this girl from a truly horrific outcome, her previous guardian was someone using her Quirk to his own ends, a man who would use his own child's flesh as ammunition against a world he hated, a type of person that Izuku hated, but that was a story for another time. Now however he had no time to think of the past, he had a terrified six-year-old too scared to see her pediatrician without him or his future lover Nanami Fujiwara, the person who adopted her after that incident when he couldn't. The girl clung to him as she walked with the soon-to-be couple, using them as a source of strength as she got her first round of shots. "Yes, that's us." Izuku relied on the receptionist, not looking forward to the appointment after her check-up and the discovery that the girl had a deathly fear of doctors.
The woman at her desk noticed the girl's fear and offered her a lollipop, Eri took it with some hesitation and words of praise that made her blush and hide behind Izuku, a far cry from the first time, she would not respond to anyone but Izuku and Nanami. That changed with the introduction of Nanami's oldest sister Makina. This older sister had a child of her own and had been taking care of Eri where the teens couldn't, that was a trying event in its own right. Makina had taken in Eri so that her sister would find some stability in her new job before really being able to take care of the six-year-old, she would have to spend time at her sister's at first to help Eri transition to not having her or Izuku around the whole time. That was a whole ordeal of its own, she had to take time off, and Izuku had to come over on the first weekend, all with Eri being a mute since the three met.
The walk to the room where Eri would get immunized was silent as Eri took both teens' hands, it was something neither had told her about hoping that the girl did not fear needles. Once they were in the room Izuku helped the six-year-old on the bed and sat next to her while Nanami sat at a chair across from them. It did not take long for the doctor, an elderly gentleman, to come in and cause Eri to embrace Izuku's arm. "Well, I'll be." The man said, looking at the pair. "I knew that I recognized the name… you look a lot like your father, is this your sister?" He asked, kneeling in front of Izuku and a shaking Eri. "Are you sure this is going to be okay?" He questioned noticing the fear that Eri had, him not being the physician that made this appointment in the first place. Despite it all the man had dealt with fears of needles before but the patients that had those fears never looked this pale.
"I honestly don't know… this is a first for us. But you shouldn't have a problem with Eri-chan with us here…" Izuku paused thinking over the first question. "Oh she is not my sister by the way… she is umm…" He looked at Nanami with a pleading glance.
"Oh… that's the fun part, I am actually her foster mother. The Midoriya part made things easier for us so that we aren't bothered by it later." Nanami said with a grin at the flushed face of Izuku Midoriya. "It's been a while and I didn't want her getting any special treatment from your staff, old man. But you know how that story went." She finished looking at Eri, shaking like a leaf.
The doctor took his time to process the information in his head, only to have his face brighten up at it all. "Well, darn. To think that rambunctious little girl from a while ago has grown up. And to think that a Fujiwara would fancy a Midoriya when I first started this clinic." The man stroked his chin being hit with a bout of nostalgia. "And of course, leave it to a Midoriya and a Fujiwara to take in a stray. I hope that today won't scare you off, I am in both of your families' debit and am more than happy to take in a third generation of you punks."
Nanami laughed as she remembered herself, she was a handful, to say the least back then, something that she would blame on her older sisters Makina and Rumi despite not knowing Rumi Usagiyama until late childhood. "I wasn't that bad, was I Kogusuri-sensei." She spoke to confirm with the older gentleman, who gave a look of dissatisfaction, that got a giggle from Eri.
The little girl watched as the doctor interacted with her two pillars of support and in that moment she had forgotten where she was, but she was quickly brought back to reality. "That's fun that you think you weren't… So…" Dr. Kogusuri looked in Eri's direction. "How about you do this quickly and not torture the poor girl any longer."
That said, Eri buried herself into Izuku's arm further. She hid her face from her surroundings in an attempt to make herself disappear from the world, which did not work. The next several minutes were a blur, and although it wasn't as bad as her 'time' with her previous guardian she could not help but feel her eyes water at the pricks in both arms as she got the first two of her immunizations. After the man was down she took comfort in the attention she was getting in Nanami's and Izuku's touches. It was a foreign but very welcoming affair. Ever since Izuku and his mentor took her from that place, the place that she was before, a place she would like to forget, she was scared that she would have to go to another place like that one. She was scared that she would be thrown away again, and forgotten. Though those thoughts plagued her that was no longer the case, like her new aunt Makina said she had a Papa and Mama who would protect her from all the bad things in the world.
Eri did not have to worry anymore, she didn't have to worry about bad things happening to the people who wanted to take care of her, and though she did not want to be a bad girl she did not have to worry about messing up even when it scared her to. Her Mama and Papa wouldn't hurt her like that man did. That man that her Papa saved her from, the man that her Mama hurt badly, the man that she will never see again. That's why she was here, that is why even if she felt scared she would go through whatever this doctor would do to her. All because she loved her Mama and Papa.
