Slice of Life AU where Touya, Tenko, and Keigo are AU students and the big three
Tenko is Izuku's adopted older brother. He has his original quirk and encouraged Izuku to go to UA to study to be a quirk analyst. Tenko is the main reason why Bakugo and Izuku are "best friends" still (As Izuku insists they are much to Bakugo's annoyance). He sorted out that misunderstanding at the river pretty early on and gets Bakugo to back off by saying Bakugo has a crush on Izuku and is just pulling his metaphorically pigtails
Bakugo denies this. Izuku thinks it's funny. Is generally just happy that him and Kacchan are on good terms
Both are friends with Shoto (Izuku says they are but Bakugo refuses to acknowledge this) through Touya and Tenko being friends
Touya is studying to be the number 1 hero purely to spite his father and shit on his career. But also because he wants Shoto to have a REAL hero to look up to (Their parents are divorced)
Keigo is still under the hero commission. He's an orphan but he works hard to be where he is now because he wants to be a hero for kids who were just like him. Though he says he wants to be a hero cause he wants to build a society where heroes have more free time
Oboro teaches class 3A and has dubbed Tenko his favorite student. Sees great potential in the kid though he's upset that Tenko's favorite teacher is still Aizawa from his first year. Aizawa finds the kid annoying but also saw great potential in him, but he cannot stand Tenko being his biggest and only fan cause he's so cringe about it
Izuku is in the general course and is pretty popular purely because he knows the big three. Tenko brags about his little brother being a genius quirk analyst and it inspired a lot of hero students to visit the general course and support course more often
Shouto visits Izuku often to talk about his quirk and how he can utilize it better. Brings his new friends along. But every time, without fail, Bakugo is always there first, already yelling at Izuku for one thing or another and arguing with him. Shouto tells his friends that it's normal and that those two are his bestest friends (Touya thinks it's hilarious when he says it ironically)
Keigo and Touya are pretty popular, Tenko is popular by proxy but likes to hang back away from the spotlight. He's not embarrassed by his cringe he is, shame means nothing to him. He just doesn't like the attention cause it takes focus away from what's important: League of Ledgends
He's been trying to convince the other two to call their trip the League of Flier or something along those lines, and he gets shut down every time
