little thing i want to point out while i was writing that meta. why izuku keeps calling katsuki “ kacchan ” .
i think izuku keeps calling katsuki with that nick because of full respect / admiration towards the other guy. now i think it’s obvious to think that nick means a lot more than we actually think of because as i said before katsuki doesn’t let people call him by nicknames less by “ kacchan ”, so here it comes the respect izuku got for katsuki’s quirk / force ( & maybe inside himself, katsuki sees that respect izuku got for him but being the proud hoe he is he would rather die than admitting something like this, but the again he is letting izuku call him with that nickname which i think is a sign ). as i said in the meta i just wrote, izuku admires katsuki’s strength & abilities & he thinks he is way cooler than him of course & we all know how izuku was such a sucker for those heroes he admires when he was in middle school & he was still a quirkless boy ( though he is still the biggest nerd ever with pro heroes / & quirks in general ). i guess this is the main reason izuku keeps calling katsuki with that nickname or maybe izuku just got used to that nick, since katsuki called him deku back in the days, & he, himself keept calling izuku “ deku ”, i think izuku just followed katsuki’s “ adressing thing ” somehow.
