This takes place when they are all 10 so obviously much older than they where in Naga unleashed 
Nagisa wakes up in the morning unfortunately the bright optimism has since disappeared his once bright blue eyes have turned dull but he puts on a happy looks for his mum and a strong look for his brother 
Nagisa exits his room 
Inko: good morning Nagisa 
Nagisa fake smiles: good morning mum 
Nagisa climbs onto a chair and eats his breakfast quickly 
Izuku: morning mum, morning nagisa 
Inko: good morning Izuku 
Nagisa: good morning bro how are you feeling 
Izuku looks a little saddened: I'm alright I got too see all might beat up some villains last night 
Nagisa: hey don't worry bro I'm sure you'll get your power soon enough 
Izuku: What but the doctor 
Nagisa gives Izuku a look:just remain hopeful izuku 
Izuku smiles slightly: ok 
Inko smiles at this 
Nagisa: (great I made him smile I wonder if katsuki is going to bully us today)
Much later at school 
Izuku is on the ground protecting a kid 
But stands back up 
Katsuki: so Deku still wants to fight 
Bully1: like he can he's just worthless 
Bully2: yeah he doesn't have quirk 
They all charge Izuku but 
Nagisa: HEY!
They all look at him 
Katsuki: oh if it isn't deku's little freak of a protecter
Nagisa: hey katsuki you still bullying people weaker than you that isn't very heroic 
Bully1: shut up you freak katsuki is the strongest 
The bully that can make his fingers longer charges Nagisa but
Katuski: don't go near him only I'm allowed to fight him 
Bully1: r...r...right 
Nagisa: so you've got some sidekicks that do whatever you say but I'd call them minions you probably don't even consider them friends do you 
Katsuki: SHUT UP
Katsuki goes right for Nagisa but using his original reptile quirk is able to manoeuvre around katsuki's attacks without much effort he got a bit burned in the process 
This carried on until Nagisa had katsuki pinned 
Nagisa: how does it feel to lose 
Katsuki however uses his quirk to blast Nagisa off of him 
But Nagisa lands comfortably 
Izuku: please stop Nagjsa I can protect myself 
Nagisa: please Izuku I'm your brother its my job to protect you
Katsuki: tch come on guys there's no fun here plus that stupid snake is a nuisance 
The two bullies however ignore him 
Bully1: let's show him that we aren't just katsuki's minions 
Bully2: yeah we are just as strong as him
