Katsuki is now doing a hero course and studying at the world famous hero high school called "UA", He made friends and stuff and also kinda has anger issues, hes now 16, And he also just kinda stays miserable ever since Izuku "died"

All Might sent the whole class 1A to a night mission to defeat a villian from one of the league of villians, the students are a bit hesitant bc it's a villian from the league of villians which is one of the most powerful villian groups but they agree to try and defeat one of the villians anyway, All Might sent them to just finish one villian from the league of villians, not the whole league of villians, and All Might told them that the villian is quirkless so it'll be easy bug be careful cuz he's really trained, when All Might said "quirkless" it reminded Katsuki of Izuku...

The whole class 1A changed into their hero costumes and started flying with their quirks to the secret hideout base where the league of villians are, the go inside the base and make sure to be real careful cuz they don't wanna get caught, everyone keeps looking at where the villians are finally Kaminari finds one villian, turns out, the other villians went somewhere else to steal some snacks, so they'll get them later, but there's one villian that Kaminari found...and turns out,its the quirkless villian that all might assigned them to defeat, perfect!

Kaminari does sign language to the other students that he found the villian they were assigned to defeat, everyone cheers quietly without making a sound and they sneakily go in where the villian is,they see that he has green wavy hair and black highlights but Katsuki gets shocked a bit bc Izuku is quirkless and also has wavy green hair and black highlights...some students are about to make a move when katsuki stops them and quietly whispers to them that he'll make a move instead

Katsuki: "...OI!!!YOU!WE FINALLY CAUGHT YOU, HAHAHA!PREPARE TO DIE." make explosions from his hands and makes them a bit bigger from his bomb-type gauntlets from his hero costume
