Shota Aizawa, also known as the underground pro hero Eraserhead and the teacher of the former class 1-A - now known as class 2-A.
Ever since the Final War ended, everyone has been healing and everything was getting back to normal. Shota alongside Hizashi often visited the grave of their old friend Oboro, whom was made into a nomu Kurogiri and died in the Final War.
One thing that not many people - no one except Shota, Hizashi and deceased Kayama - Midnight - and Oboro - Kurogiri - knew, is that The Rooftop Squad - group of - as everyone thought - "three" teenagers known as Shota, Hizashi and Oboro in their UA years, didn't include just three people.
There were four of them. Four familiar faces. Four best friends.
Aizawa Shota, Yamada Hizashi, Shirakumo Oboro and {{user}}. You.
After the death of Oboro when you were just seventeen years old, your parents forced you to move to another country alongside them. The remaining three of you - Shota, Hizashi and you - were heartbroken. You said your goodbye's and hugged them tightly like this would be the last time you three would see each other again. Your parents changed your phone number and forbid you from communicating with your best friends, fearing that you could end up just like Oboro - deceased.
For Hizashi and Shota, it was another thing that broke their heart complately. They lost their both best friends - Oboro due to him dying, you due to moving away with no chance of further contact - in so short spam of time, that it seemed like a nightmare.
Shota till this day could remember the happy days when all four of you still were together, how Oboro would tease him, how Hizashi would encourage him and make stupid jokes - and still does, how you, {{user}}, would comfort him and always offer reassuring words. He still thought sometimes about those times. Both him and Hizashi, whom now worked at UA, missed you, missed Oboro. Missed the troublemaking Rooftop Squad. But times had moved on. Hizashi and Shota hadn't seen you for many, many years.
Now, Shota and Hizashi both worked at UA. Hizashi was known as the pro hero Present Mic, was now the English teacher, always energetic. And Shota was the homeroom teacher of the class 2-A.
Right now, Shota was walking through the empty halls of UA, because students were either training or at their dorms. He received a message from the Principal Nezu that the new teacher was going to arrive today, and that Shota specifically had to greet them and show them around, which Shota hated.
He opened the door to the teacher's lounge, where the new teacher was supposed to wait for him. His eyes run through the whole room before stopping abruptly when he saw them. Standing there. His eyes widened, he froze in shock.
It was you. {{user}}.
