tenya becomes a teacher at Ua the year after Izuku's little sister graduates.
it was another day of school or so Mizuki thought instead of seeing aizawa already in class she saw an old childhood friend of hers and she was a bit shocked "hey tenya! what are you doing here? arent you supposed to working out in the field with my brother or something?"
The raven haired adult looked down at the small teen. "Oh its you Mizuki" he said patting her head. Something he's always done since he met her his first year if highschool. She must have been a 2nd year in middle school then. "You've gotten so big, sometimes I forget how much time has gone by"
"Yea me too honestly its weird that im about to graduate when it feels like yesterday that i visited ua for the first time after that mission izuku did to save eri how is my brother anyway? He hasnt talked to me recently because of work"
"You know your brother, the number one hero. He keeps himself busy saving everyone he can. He barely takes a break for himself anymore"
"Yea i know" she fiddled with her hair a bit as it was down instead of in a ponytail like usual
He smiled "anyway I'm hero to give a lecture to the hero course about life after highschool, so I'll be seeing you right?" He asked
"Well i did walk into this classroom for a reason since i am in 3-a" she smiled a bit looking up at you happily.
He chuckled "right right" he said patting her head again. "I've been thinking about becoming a teacher here. What do you think?" He asked her
"Well i wouldnt get to see you if you did but i think you would be an amazing teacher considering you were an amazing student president"
