Midoriya Inko gradually begins adopting various kids and vigilantes into the Midoriya family
it starts with Toga Himiko.
Izuku is 8 years old and allowed to go out by himself to play at the park. (the benefits to being in good terms with most of the vigilantes and even some heroes in the mustafu prefecture)
Toga Himiko is 10. She’s been living in an orphanage for as long as she can remember after her parents were jailed for villainy. She happens to be at the same park as Izuku the same day.
Izuku is approached by a gaggle of bullies looking to beat down on the kid who’s been becoming a nuisance lately.
Izuku’s been getting self defense lessons from his mom’s friends for a year now, but he’s still small for his age and his twiggy arms can only do so much against the bigger children.
Himiko sees this: she remembers how kids used to bully her for having villain parents and a quirk seen as gross. She decides to Not Tolerate this happening to that kid.
cue Himiko walking up and throwing a punch at the ringleader of the group. After that one goes down, the rest of the group scatters.
Izuku is in awe of this girl, who defended him from the pretentious local children.
Izuku and Toga talk and play, cause who cares if they were two years apart, they’d found kindred spirits in eachother!
Izuku takes Toga home for dinner (and to beg a sleepover).
that night is Inko’s night off, and she made a good meal and had a movie set up for when Izuku gets home.
Izuku and Toga arrive, and Inko is understandably delighted because up until now Izuku’s only friends were the frequenting vigilantes, her, and a long time ago, Katsuki Bakugou. (Inko nipped that in the bud. Katsuki was given counselling and it was determined best for the two boys to be separated as much as possible)
Dinner shenanigans ensue.
After dinner, Inko is begged by the two kids to have a sleepover. Inko agrees, but asks for Himiko’s contact information to check with her guardians.
Himiko tells inko she lives in a local orphanage.
Inko has a steady(ish) income, an extra room, and a lonely son. so, she calls the orphanage, gets permission for a night’s custody, and sets an appointment for the next day to discuss options.
Inko talks with Himiko that night, after bathtime and the movie, and asks if she would like to stay.
Himiko agrees.
The next day, they’re given a month to settle in as a trial, and then they can sign the adoption papers.
