It's Yarmiko!

as of currently, i'm not really sure how the other units will work, but i do know that it will be based on the separate station masters of the real life collab:

kirby for tokyo

dedede for osaka

mk for nagoya

& with station masters comes units, & with units comes staff, which is where our favorite allies come into play:

in kirby's unit is magolor, who's only interest appears to be the fame it will bring him. despite being part of the most popular unit throughout japan, magolor wishes to be recognized, unhappy that he is simply regarded as another employee of japan's top unit, with kirby taking all of the press & fame

within dedede's unit is taranza, who finds trains to be a great solace after applying to the osaka train station as an internship during his stay at osaka university & since then has become a full time employee, working as the assistant station master. he appears to be romantically interested in a woman named sectonia who frequents the station. it's unknown how she feels about him though.

& in mk's unit...IS SUSIE, WHICH IS WHERE I'M GOING TO TAKE A HUGE DETOUR TO JUST TALK ABOUT (because i legitimately do not have this entire thing fleshed out despite it being over several months since this ask was sent in --again, i apologize.)

so, let's talk about susie! (best girlfailure 😍)

susie is an employee of the nagoya station, currently working as assistant station master. she's built her entire way up to her current position, initially working as a humble customer service worker to within several months the position she is currently after proving her worth through helping during dire situations at the station with her extensive knowledge in engineering

she got this job from taranza, an old high school friend of hers that she managed to keep in contact with. aware she was going to graduate from tokyo university soon & wanted to continue living there afterwards, he told her that job applications for all the train stations were opening up soon & recommended she start there in order to get some good experience or at least build a stronger resume for the future, even doing her the favor of recommending her specifically to kirby. although it didn't really seem to entirely work out unfortunately --good job on taranza for at least trying though, we all need a friend like him frfr 💯💯

unfortunately, even after climbing up the ranks, she's still somehow considered a nobody, often relegated as another typical staff member of the station. to add to her frustration, there's a frequent rumor regarding whether mk even has an assistant station master as he's known as "the lone station master" (DO YOU GET THE REFERENCE 👁️👁️). they assume that whoever they are, they seem to rarely make an appearance (despite susie's near perfect attendance, even in comparison to mk himself)

well, now that i've mentioned mk, let's talk about him too:

unlike susie, mk is simply said: the literal face of the nagoya station. everyone knows about him & likes him--he's charming, he's eloquent, knows class, & although he can be overly elaborate at times, people like that about him --he's just a very DEMURE man in general (I WROTE THIS PART WHEN IT WAS STILL FUNNY PLEASE LAUGH 😭)

on the other hand, susie DOES NOT like him very much!!!!!! she finds him EXTREMELY annoying, a HUGE attention seeker, & VERY irrational

because of this, mk enjoys picking at susie as a pastime activity, especially over the fact that instead of getting a job for kirby's unit, she ended up working at mk's unit due to her father's address being in nagoya, the cause of it all

even though mk's a frequent dick to susie, he DOES see the effort she puts into her work & greatly respects as a result. after all, how did she get promoted to assistant station master? vul could've taken it as the longest standing senior member of the crew but mk chose susie instead

generally said, these two essentially have this rivalry on who can piss off the other most, evolving from "i hate you, i cannot stand you & i want you to know that all while NOT losing my job ^-^" to kaguya-sama: love is war type shit as they're both DEFINITELY into it & DEFINITELY into each other

small detour for those who haven't watched or heard of kaguya sama: love is war, it's a great romantic comedy anime/manga & i recommend watching/reading it if you ever find the time & you're into that kind of stuff, very cute & very funny

anyways, going back to susie, despite susie's attempts to piss off mk herself, unlike mk's more...elaborate ways of pissing her off, she typically has to go for the low blows which typically never works or if they do, he immediately gets back at her or if it really pisses him off, he will straight up pull the "i'm your boss." card which is a line susie wishes to never cross as long as she lives!

outside of mk, regarding her relationship with the rest of the nagoya station unit, she's relatively neutral as she doesn't really talk to any them much outside of work, the only person breaking that rule being sailor dee, a junior staff member who she currently supervises with vul who, as stated previously, is a senior staff member. she enjoys spoiling sailor dee a lot & views him a lot like a younger sibling. she finds his passion for engineering inspiring & she can see a lot of herself in him

however, she does know others outside of her unit, such as magolor, who she met through taranza. as an interesting tidbit, out of the three, magolor is the youngest (& shortest), being 20 as he went to study abroad & graduated early before returning back to japan. taranza meanwhile is the oldest (& tallest) of the three, being 23. susie meanwhile is 21. (for anyone curious about mk's age, he's 24 in this au, which would mean susie & mk have a 3 year age gap)

mk really doesn't like magolor & doesn't want susie to be in a 10m radius of him, & although he doesn't know much about taranza's relationship with susie, he still doesn't want to take any chances

in terms of mk's own relationships, besides the wave 3 trio, he's basically buddy buddy with the rest of the nagoya station unit, absolutely adoring him. in terms of the other two station masters, he's best buds with dedede & views kirby as a younger brother, similar to how susie views sailor dee

going back to susie once again, although she does enjoy her job, she does wish she could maybe transfer to other units because they include closer friends such as magolor & taranza. however, whenever she looks for the transfer applications, they never seem to be there despite mk's claims of restocking them every single day. furthermore, whenever she goes to print out one out instead, the file is also corrupted to a degree that even susie can't save.

even more suspiciously however, the one day mk forgets to hide the transfer appliations & witnesses susie take one (he definitely had heart palpitations after witnessing her actually do it), he has never received the application back from her.

now...i've been waiting for this part for a really long time now as this has practically been in the back of my mind ever since i received this ask...THEIR BACKSTORIES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

since susie's isn't all that interesting since she already gets tortured by mk, i'll start with hers first:

ever since she was born, susie has lived comfortably in nagoya, practically surrounded in wealth. however, this was all without her mother, who had shortly passed away after giving birth to her, thus the only parent she's ever had is her father. she's only heard snippets about her mother, but because she's never actually met her mother, she doesn't feel particularly close to nor all that curious about her

going into the logistics of her wealth: it is primarily old money, both of her parents--similar to her--born into wealth inherited from past generations. however, in spite of primarily consisting of old money, haltmann would eventually manage to hit it big through an ice cream machine & other similar appliances business he called the "Haltmann Works Company," thus the haltmann family would become a combination of both old & new money, so now…they've just gotten richer!!!!!!!!!!!! however, in terms of their ways & methodologies, they are VERY old money

despite the company's large success however, haltmann & susie would over time become much more distant: haltmann focusing on taking care of the company over his daughter & susie rarely ever able to see haltmann

however, as a still young & naive child, in order to feel some sort of closeness to her father again, susie would be inspired to share similar interests with her father, & would begin to secretly attempt to create inventions on her own

this would eventually cause her to get into a freak accident, leading her to retain a large scar on forehead hidden beneath her bangs & experience mild nerve damage on both arms that she would fortunately completely recover from after several months of physical therapy

however, at the moment, haltmann--fearful of what the press would say & the potential decrease in profits--would close her off from majority of the world, forcing her to keep her distance around others & a relatively low profile, even long after her recovery

that did not mean that he completely did not care for susie though, as during her slow recovery, haltmann would gift susie her mother's favorite silver pocket watch, "Star Dream," within it an old photo of him & her deceased mother carrying susie when she was around two months old.

unable to normally interact with others beyond the haltmann household now, susie would develop a large inferiority complex as she grew up, feeling the constant need to appear flawless & perfect. this would culminate into her often masking in many social situations, especially business related ones

regarding susie's school career, she lived her life going to the best private schools, receive perfect scores all across the board, took multiple extracurriculars --she was essentially your stereotypical perfect student

as stated previously, in high school, she would meet taranza, who was two years her senior & had similarly came from a wealthy background of old money. he would be the only person susie would ever consider a friend, her first real friend even (TARANZA SNATCHED THE TITLE FROM MK, WE LOVE A QUEEN LIKE THAT 💅💅💅)

however, despite being the supposed perfect student, susie was extremely emotionally stunted & very socially awkward, often keeping everyone at an arm's length & unwilling to let her walls down to anyone, not even taranza. she would get by through masking, using it as a defense mechanism--as if it were her against the world--& as a result, unintentionally isolating herself further.

after graduating high school, thanks to her extremely successful high school career, she would be immediately accepted into tokyo university, graduating with a bachelor's degree in mechanical engineering

susie found tokyo university to be a breath of fresh air, a place where she felt she could just be: normal. she felt free during her time there, especially free from the constraints of her father. even though she still felt the need to keep up her prim & perfect persona--as the effects of her past basically already taken root deep into her identity--she nonetheless felt...free.

unfortunately, after graduating tokyo university, haltmann despite his success had been significantly dwindling in health, his health finally reaching a peak immediately after susie's graduation, falling into a crippled state

susie would be forced to go back to nagoya in order to take care of him & the haltmann household, frustratingly postponing her desires to pursue a life in tokyo but also causing her to feel an unreasonable sense of extreme guilt over the fact that she even wanted to abandon her responsibilities in nagoya to pursue her own aspirations in the first place (i specifically state "unreasonable" as it is not her fault for her father's poor health despite how she may feel, there is absolutely nothing wrong with pursuing your aspirations, even if they might be different from what is expected of you by parents & peers)

however, over time after being hired & continuing to work at the nagoya train station, she would eventually find her job to be a blessing in disguise as despite losing opportunities to pursue a life in tokyo, she would be able to reconnect with her father & finally let down her walls (THANKS TO MK), developing genuine relationships for the very first time (HER FIRST ONE BEING MK --lowkey i feel like this is how mk would act, just a huge egomaniac, but he does so as half joke, half who he really is)

as a semi un/fortunate little tease: susie will eventually move on from her job as assistant station master to fulfill the new aspirations she's found after working at the train station. the good news however, is by that time, she'll be in a romantic relationship with mk (MAYBE EVEN MARRIED WHO FUCKIN KNOWS!!!!!!!!!! (i don't)) & still live in nagoya…with him. :DDDDDDDDDD

however, unlike susie's backstory, mk's is much sadder...because he's mk & there seems to be a large consensus that the fandom must torture him in some way 👍👍👍 (ALLEGEDLY ALLEGEDLY ALLEGEDLY, IN FORTNITE, IN MINECRAFT):

mk came from a middle class family with the typical stay at home mother & breadwinner father, thus living a fairly decent life in nagoya

however, while mk was still in middle school, his family would suffer a horrific car accident that would only leave him as the only survivor of the tragedy

this would quickly worsen as immediately after his parents' funeral, he was siphoned of all of assets, including his own house & essentially abandoned by the rest of his family

this would cause mk to become bitter & resentful of others, & he would establish a negative outlook of the world

with no money or home to go to, he had to immediately drop out of school after completing his middle school education in order to find a job --being just barely eligible enough to apply for any sort of occupation

fortunately, he would eventually find work as a full time janitor at the nagoya train station

there, he would meet gk, the current station master at the time --though during the first few months, they did not know each other very well--gk barely aware of mk's existence--only aware that they humorously shared the same surname despite not being related

however, one day, due to extreme exhaustion from working overtime literally every day & obviously not in the right mindset as a high school dropout who essentially lost everything, mk would nearly fall in front of an upcoming train, gk being just there enough in the nick of time to save mk

from that point on, gk would learn more about mk, primarily using vul as his main source of information (as mk would only talk to him out of everyone else in the unit)

through this, he came to the decision that he would help mk out, acting as his guardian, especially after learning about his orphan status

as his new guardian, gk would send mk back to school. however this would not be an easy task as mk didn't want to lose his job due to school (fearful that gk might abandon him like the rest of his remaining family did as well as potentially siphon all his money). thus gk would compromise, changing mk's schedule to part time during the weekends as well as personally pushed to pay for mk's expenses until mk was financially stable enough to move out as mk could barely afford any sort of rent or even groceries--but most importantly of all--afford a normal life again.

in addition, after graduating high school, gk & the rest of the current nagoya unit of that time would pitch in to help mk go to a junior college where he would pursue a major in mechanical engineering & achieve an associate's degree

living with gk would really change mk's initial negative outlook of the world to something much more positive. he can attribute some of his current eccentricities from gk such as his charm & borderline irrationality/overly elaborate nature as well as enjoyment for picking at susie (as gk teased him A LOT, though in a much more lighthearted way than what mk does to susie)

once finished with his studies, mk would move out & slowly climb up the ranks until he became assistant station master himself & eventually the new nagoya station master after gk’s retirement (who was at that point in his mid 70s, my man just enjoys trains yk)

after becoming the new nagoya station master, gk would gift mk his old gold pocket watch called "Galactic Nova"

he would work as the new station master for a bit over 3 years before meeting susie

funny little tidbit about gk since we've practically reached the end:

gk likes to call susie "mk's girlfriend," even before they were in a relationship (HE CAN SMELL LOVE FROM 1000KM AWAY)

he initially did this as a joke, but when it became real, he switched it up to "mk's wife." idk what he's gonna call her when she actually does become mk's wife. maybe just susie.

furthermore, when he learned susie called mk "Yumeta," whenever he refers to their relationship, he calls mk "Yumeta-chan" to get under his skin, but normally, he calls mk "Meta-chan" --unironically. he really enjoys using the "chan" honorific for mk & when i think about it, probably everyone. (this is a big headcanon of mine that goes beyond just this au)

eh, he's a retired old man, he can do whatever he wants as long as it's not illegal
