time to giddy tf up y'all

the majority of my daydreams revolve around fight scenes/battles + feature some sort of skilled MC cause i looove fighting choreography. so i kinda always write about an MC who is competent in some way, shape, or form. but unfortunately, fighting doesn't translate the best to writing. and demon slayer has like, some of the best animated fight scenes, so i think abt KNY a lot even tho i didn't like the story that much

i so badly want to write some sort of jjk and LU crossover, featuring a sorcerer!reader. kinda obsessed with maki, hakari, and kashimo atm. just, OP power system mind go brrr. thinking of them trying to understand "cursed energy" and how it's not actually cursed or bad

and then i'm also kind of in a spiderman zone rn?? and also i still have omegaverse thoughts, so all of this shit is just getting rammed together like a horrific car accident, none of it making sense outside the context of exactly one (1) scene

ANYWHO!

one of the first things that comes to mind with demon slayer!reader, is that the swords are completely different. what the LU boys use is suited for heavy armor, thrusting, and powerful blows (going w/ general longsword). and—although unrealistic—they have their scabbards on their back

katanas are really for unarmored/lightly armored enemies. and a recurring detail in KNY is that the katana is very weak when used improperly. they're made for deadly sharp cuts and slashes with only one edge of the blade. striking or getting hit on the wrong edge will lead to a decent chance of it breaking. their scabbards are on their hip, making their draw quicker (typically longswords are also like that, but media puts it on the back cause it's cool and sexy)

so how does demon slayer!reader fare in an LU context?

fine, probably. you have a new sleep schedule since you can now rest at night lmao. the LU monsters aren't armored, and the ones that are have very notable gaps/weaknesses. so there's no issue with striking them down.

in these lil thoughts, i like to imagine that reader is a hashira. you'd need them to be skilled with the blade, cause now you're literally screwed if ur blade breaks here. whatchu gonna do if it breaks? learn how to use a longsword? not impossible, but hardly desirable

another point, reader is probably fast af, and stronger than them. demon slayers are all fast, and in most fighting situations, speed tends to beat power. combined with the sometimes inhuman strength your breathing technique provides you with, reader is going to be perfectly alright in this world

i'm not gonna go too in-depth, but these are the things i'm thinking of from the top of my head

Four is obsessed with your sword and fighting style. it's so incredibly unique and different, and whoever crafted your blade was clearly a skilled swordsmith

they all looove to see you demonstrate your skills or duel them

in a duel, Time is troublesome because of all his armor, but it's easy to target his elbows and legs that are unguarded

his blows are very powerful though, and parrying him is not the easiest thing in the world

duelling with Warriors, Wild and Sky is always fun, because i consider them to be the fastest/quickest amongs the nine for the most part (excluding Legend's boots)

but i do consider reader to be faster since you won't have all that armor and gear weighing you down. and your breathing technique is literally giving you a mega power boost

speed beats power!! and their armor is unfortunately made for looking and not using; they have weaknesses that can be exploited pretty easily

speaking of speed, the pace at which they travel bothers you a little, because you're used to going both faster and alone

Wind would think you're the coolest person if your clothes weren't so weird. socks and sandals is an interesting fashion choice around these parts. and why are your pants so fluffy?

surprisingly, Sky is succesful-ish at mimicking your breathing! it's not very good, but with what he's gotten down, his asthma has improved and fighting is now easier. if he wasn't already their top swordsman before, he most certainly is now

you suggest to him that a different breathing style could be good. to you, it seems like a compatibility issue for the most part

you've beaten Twilight a few times (but not always) in arm wrestling. you two once had an impromptu wood cutting competition, and you won by a landslide from speed

they're all interested in learning about your world and the foes you have faced. you tell them about how you earned your hashira ranking and the kizuki you killed for it

assuming pre-infinity castle, Muzan is still around and you talk about the demon slayer corps' mission, how you're dedicated to eradicating him and his followers to hopefully rid the world of demons for good

they all think you're incredibly brave and courageous. it takes a certain kind of will and soul to be able to dedicate your life to such a service, especially when most of the known world remains oblivious to the threat

not all of the enemies you've face have attack patterns that you can exploit, unlike their ones. you need to understand their techniques and see how to outmaneuver them

in that sense, fighting monsters is easier here. so much so, that Warriors often treats you like a one-man team when they need to split up
