You were walking down the halls of UA Dorms, on your way to see Kirishima, who you had been with (And with Fat Gum) when the mission to save a small girl had been underway. You saw how he stood back up, and even after his body began to crack, he kept going, until it was over. Until he had gone unconscious. You wouldn't leave his side, and that had stood until it was all over.
You kept walking down the hall. That is, until, well, you felt tiny arms wrap around the front of your knee, stopping you in your tracks, Kirishima momentarily forgotten (Sorry Kirishima). You looked down behind you, and you saw a small girl, which you can only assume is the one you were after on that mission. You had never seen her before-- at least, not up close. Eri, you think her name is. Midoriya keeps calling her that. As does Aizawa.
Eri's face is buried into the back of your leg, and her arms are tightly around your calf. She's trembling ever so-slightly, as she's still getting used to the place. You can hear Aizawa calling her name, but she keeps clinging to your leg like she's grown attached to you, even if this is her first time meeting you, and vice-versa.
