Headcannons for older sibling reader? I saw your one with the really young reader and I give you this; older sibling reader with the brothers being small kids
Oh boy, this is interesting.
Now I’m thinking about more like a daycare kind of situation where the Reader walks past everyday to and from U.A.
One day, you notice there was a spiky haired boy being picked on by some older kids and your immediate appearance scared them away. He yelled at you that he didn’t need your help and that you shouldn’t look down on him, all the while tears streamed over his cheeks.
But he let you wipe his tears anyway, taking care of the little scrape on his cheek with one of the multi-colored band-aids you carried around.
Like the ones that wrapped around each of your fingers and moved down over your arms.
You led him back to his daycare and the both of you talked about your quirks, that and he get super excited that you were going to U.A. and studying to become a hero. You learned his name was Katsuki and he also introduced you to his friends, a little half-haired boy named Shouto and a greenet named Izuku.
From then on, everytime you walked by in the morning or afternoon, they’d rush to you and say hello. You’d always greet them in return, bright smiles and colorful band-aids and all.
After being taken in by Yagi, your health and attitude improved and you came to see them more often. They had taken to following around like ducklings when their teacher allowed you to stay. Vowing to yourself, you’d keep them and children like them safe.
Especially as the words “Mochi” and “Mocchan” slipped from their lips and the term ‘sibling’ was used.
