hi! i'm rumi (she/they) 25+ in pst. i haven't tumblr rped in a loong time so please bear with me 🙏 also thank you to those who have dmed me it's so welcoming here already! i'll be replying to you all soon once i've read all your muse info but please don't hesitate to lmk if you have any ideas from this post!
my muse gahyeon is a firefighter with phoenix mimicry, her background is under the cut! you can also find her about here (this also has her background that's below) and her power description here! at the very bottom are some connection ideas, please like this post if you'd like to plot and i'll slide into your dms! (also if you can't tell already i'm a huge yapper sldkf)
background
the daughter of two very well known retired guardians, kwang jinah and kwang sungho
gahyeon was expected to follow in their footsteps, especially with her powers — phoenix physiology could be perfect ability for a guardian to have
she began private training with her parents at a very young age, they were adamant on having her reach tier a like jinah or tier b like sungho, and she showed great promise
she was a good kid and did everything her parents told her to do as they put other tiger parents to shame with how controlling they were
her parents would encourage her to follow the news at a young age, thinking this would give her more passions about being a guardian but this did the opposite as she saw how the humans were living compared to the mutagens back home
her passions began to shift as she wanted to help her people rather than humans, she just had to find a way to stand up against her parents
she didn’t tell them until it was one day before she had to apply for the guardians
they weren’t happy when she told them but they didn’t push back as much as she thought they would, almost as if they too felt compassion about how district x was being treated by the korean government. though this didn’t stop their one off comments
instead she applied for the district x fire department
the pay isn’t the best but she feels fulfilled and happy, like she’s actually making a difference for the people she cares about
due to this she still lives with her parents at the villas and even if she never hears the end of her parent’s subtle comments about a career change (so she could at least have a better wage), she endures it in order to have a nice home and a stable flow of money
she tries to justify her compliance by using her parent’s money for work supplies, since the fire department doesn’t have much funding
there are only a couple people at the fire department who know who her parents are as she tries to keep that knowledge to herself
she loves to go out, finding freedom in the nightlife. often goes home with others, especially if that means she doesn’t have to go back home to her parents nagging at her
she’s always thinking of getting a second job so she can move out, but being a firefighter means you’re almost always on call so she can’t. however, the thought of finding a rich partner has been crossing her mind lately
wanted connections (can be mix and matched!)
friends
clubbing friends
gym/workout friends
shopping friends
current/past fwb
current/past situationships
exes
enemies/don't get along/frenemies
bad influence (either she is a bad influence or they're both girls who say exactlyyyyy to each other)
neighbors(ish) she lives at the east side, brick stay villas apartment complex building #c201 with her parents
childhood friends (would know who gahyeon's parents are)
your muse knows how gahyeon's parents are, not childhood friends
she helped/saved your muse from a fire, could be interesting to have a white knight syndrome connection!
your muse privately trained with her when they were both young and they are now in very different places professionally, or maybe they both didn't want the guardian life
your muse is rich (or just richer than her) and often spoils her so she hits them up often
your muse is a huge fan of her parents and keeps talking to her about them, begging for a meeting with them
gahyeon has begged your muse to pretend to be their partner to get her parents off her back. depending on your muse's job they might have to have a fake one to impress her parents
your muse and gahyeon often meet late at night (either twice or once a month) and just talk about life. things they wish were different, things they're happy with. anything to just get off their chest. the thought of running away together is always brought up but never pursued. by the end of it gahyeon always falls asleep since they talk for so late and has to be woken up by your muse. sometimes they'll see each other in passing outside of their rendezvous but they don't say much besides a quick hello.
your muse and gahyeon are always talking about moving in together but they need the money first
gahyeon is the personal trainer to your muse either for self defense or just for fun. either way, she doesn't ask questions and only cares about getting paid
also very down to brainstorm if none of these match your muse(s)!
hi hi hi, and happy opening!! so excited to be here with you all! i'm sage (she/her, 25+) and i'm here to introduce you to my lovely zyra! (i also have jae over at @jaedx and luce at @lucedx, intros for them coming shortly!)
mizuno akari aka zyra is a tier d guardian with the power of floral physiology. which kind of means her body is somewhat like a plant! her powers are heavily inspired by zyra (league of legends), poison ivy, flora (winx)! her profile (including background) can be found here, but i'll leave a short tl;dr under the cut along with some connection ideas because i've been too scatterbrained to make a page. please leave a like if you'd like to plot with zyra, and i will find my way into your dms!
tl;dr
born mizuno akari, from the outskirts of kurayoshi, japan, only daughter of a couple of rice farmers.
a quiet but lonely child. spent most of her time playing in the fields and forest near her parents' farm.
her powers manifested when she was in 2nd grade, and despite having parents with relatively weak powers, her turned out to be quite strong. she couldn't control them, which led to an incident at her school: during a stressful moment in class, she started releasing pollen that made everyone else in the classroom fall asleep. this had her permanently branded as a freak at school.
her parents didn't really know what to do bc like things were kind of bad for mutagens in japan?? so they decided to give up on the farmer life (rip) and move to seoul instead, because district x seemed like the best place for them to raise their daughter.
took a few years for her to feel comfortable in a new country and the new language but once she did, she actually made friends??? for the first time in her life?? so akari felt like she was having the time of her life i'm ngl.
started idolizing guardians during her teenage years.. like they were soooo cool to her and she just wanted to be like them, especially the tier a ones!! took her parents a lil time to fully be on board with the idea, but they eventually agreed and let her enroll in the heroes of tomorrow academy.
started going by zyra when she was accepted into the pinnacle institute at age 19!! and started training to become an a tier guardian once she graduated, which she was ecstatic about
she's on track to be promoted within the next few years, after having been a d tier guardian for five years now. though at this point she's realized being an a tier guardian wasn't all she thought it would be, but she still doesn't really see herself doing anything else, at least for now.
plot ideas
friends from high school?? like they would have been the first friends she ever made potentially... she's a bit of a hag tho since she's 29 so would have to be someone around the same age.
classmates from the pinnacle institute! she graduated in 2020! (i think, don't quote me on it i'm terrible at math and timelines)
any fellow guardians hmu... especially the ones in a and d tier — for the a tier one, she might look up to them? and the d tier ones i imagine she sees quite a lot.
neighbors, she lives in top view towers! but on the first floor bc she doesn't want to be too far off the ground... she's a good neighbor i promise like she'll water ur plants for u if u need to be away... or she could just help u keep ur plants alive in general?? maybe start a rooftop community garden with her?
past relationship(s)... for now i think she's probably had about 1-2 somewhat serious partners in the past, and potentially a one night stand or two but she's not really made for casual. open to exploring this tho!!
in addition to the previous relationships mentioned above, i want her to have one super devastating past relationship like. soul crushing. totally up to brainstorm what went down but i'm thinking it was like, a formative heartbreak for her, that taught her how much love could hurt.
maybe someone who admires her idk. big fan of her work w the guardians idk like since she's training to be an a tier guardian i'd imagine she's at least a little bit known to those who care about guardian business at least.
idk i'm kind of good at brainstorming sometimes i promise... pls plot with my girl 🤲
ahaha aye its ya girl, nana (25+, she/her, gmt+0)
bringing you an unstable high achiever detective constable kang hyunwoo!
26, leo sun&ascendant, virgo moon
district x born and bred
detective constable at the district police
proud display of physical attributes from his ability
if youd liked to plot, hit that heart or slide in my dms x
dc available @ nanathingz
cw; mentions of anxiety, aggression, anti social behaviour
hyunwoo was expected to join the police force as soon as his ability manifested, too similar to his dad's to go to waste
so his childhood was pretty much guided by both his mum and dad, making sure he was going down the right route
he had very few issues growing up, the biggest ones being aggressive behaviour which he was quickly enrolled into therapy for that; he still goes to this day whenever his anxiety and aggression seems to spike, just to keep a lid on it, but he had grown into some healthy coping mechanisms
he joined the police academy as soon as he could, doing extremely well, graduating at the top of his class, but nothing less was expected of him
he is a workaholic, like, heavy workaholic, he was the kid that would do extra work and extra activities to get those stupid credits he didn't really need
his days as a patrolling officer have had their ups and down, he has had his fair share of injuries that left him bed ridden for weeks, only a handful of failed cases; he was doing really well for himself really
developed multiple secondary abilities due to how stressful his time as a patrolling officer got, especially because he was often send around the lesser favourable districts and he really just wanted to do well and survive
he has done all sorts of dirty work for the police force,
he works even more nowadays, especially because his anxiety and antisocial behaviour grows when he is restless
he recently passed his detective exam and hopes he no longer has to see the examination committee for a good while; his parents are very proud and hyunwoo feels that as well to an extend
possible plots;
someone who he arrested while an officer?
someone he helped while an officer?
colleagues from the police station? course mates? childhood friends?
first aid responders or fire brigade people he has made friends with because their cases have overlapped
he has a surprisingly good work life balance and large groups of friends; he has met a lot of people in the most random situations and places and has managed to make friends with them
someone who doesn't like his physical dog like features? he doesn't care, will try and use your arm as a chew toy if you annoy him enough
someone who doesn't like the fact that he is in the police force
someone who calls him about anything and everything they think hyunwoo can help with bc he is a police guy
running/gym buddies please its his bread and butter
ahaha aye its ya girl, nana (25+, she/her, gmt+0)
bringing you mildly traumatised power amplifier and c tier hero kim jimin!
24, capricorn sun&rising, pisces moon
district x born and bred
c1 tier hero, was on a 6month sick leave
slowly being integrated into the workforce again
if youd liked to plot, hit that heart or slide in my dms x
dc available @ nanathingz
both parents have technology based abilities, own a rather successful tech company
had a very quiet and happy childhood, wasn't extremely social but was well liked
she didn't really know what she wanted to be when she grew up
eventually, she went to the pinnacle institute of mutagenic excellence at age 16
a lot of things clicked in for her at that point, her power, her role, her lack of identity
she really struggled to make any actual friends, and connection during her stay there
most of her friends are from tutors pairing her with unstable classmates or classmates that needed an extra boost of morale
she is indeed practically useless on her own
she graduated with good grades and within a few years she was put under c tier heroes
she loves it tbh, the lack of publicity, the lack of dealing with anything that makes her a public figure
she was doing really well, enjoyed her role and her job, was getting out of her shell and actually making an effort live
tw: mentions of death;
about half a year ago, she had a very bad mission that went to shit. a pure failure with a few trusted and dear teammates not making it out;
end of tw;
she developed her secondary ability during that encounter which due to the stress and trauma, she was out of work for a few months, fighting with brain fog, struggling to control her new ability and going on a bit of a self destructive behaviour
she is doing better now, only recently allowed to come back to work but is still kept under a watchful eye in case she starts deteriorating again
possible plots;
people from the institute that she had to help stabilise their powers, physical abilities or just needed some time with someone who could balance them out
work colleagues? old or new teammates? those who think she is to the incident and think she should still be out of commission? those who pity her and help her get back on her feet?
random people she made bad decisions with for a few month while not working and she suddenly vanished after that
she has her own mentee, but she doesn't mind having another one on the side; or maybe your muse really wants her to be their mentor?
other c tier heros who have mixed opinions of her, some thing she is the shit, others think she is shit. fun work dynamics!
hello, friends! here to present to you (my final muse) ivo michiels, a mutagen pacifist who’d rather use his gifts for art and protecting people. as of late, he serves as an art instructor for the local community. on the side he’d paint and busk as well. he’s inspired by real painters like renoir and gogh, how he applies his powers is very reminiscent of sai. i have a not-so tldr version of his background below the cut. additional stuff like playlist and pinterest board should be on my pinned post, if you want to have a look. as far as connections/plots goes, i prefer to brainstorm. now, if you want me to pop in your dms, just leave a heart!
born in 2002 on the cornish coast of england, where the sea was both playground and teacher.
his mother, claire michiels, a registered telepath with psionic resonance, worked as a consultant for the early british mutagen observation program.
his father, thomas michiels, a hydrokinetic, taught him that “water remembers every touch”—a phrase that became his life’s mantra.
the family lived quietly near the shore, away from the politics of london, tending gardens of sea grass and collecting driftwood.
ivo’s childhood was gentle but isolated—no neighbors, few friends, only the rhythm of the tide and the quiet hum of his parents’ abilities filling the air.
his mutation surfaced at twelve, during a school field trip: a girl fell into the current, and ivo, without thinking, reached out. witnesses said the water “rose to meet him,” forming a shimmering cocoon that lifted both to safety.
the mutagenic oversight board classified his hydrokinesis as stable yet advanced, citing his instinctive control as “an anomaly of inherited synergy.”
his father saw potential; his mother saw danger. he was taught restraint first, creation second.
by fifteen, anti-mutagen protests had begun across the u.k.—waves of fear dressed as patriotism.
during one protest near their coastal home, thomas used his powers to shield civilians. he was killed by extremists who accused him of “playing god.” the footage went viral; the sea turned red that day.
ivo and his mother fled the country under diplomatic protection, arriving in district x months later.
he began teaching art at a small community center—children, retirees, anyone who wanted to create.
his exhibitions, like waterlight and echo tides, combined hydrokinesis and psionics: water forming ribbons of suspended paint that followed his voice and motion.
he uses his powers only for art and protection, never for combat. his philosophy: “creation is defense enough.”
ironically, ivo fears large bodies of water—never swims, never sails. he says, “the sea doesn’t forget what it takes.”
whales often appear in his work, rendered in deep blues and silvers. he says they represent his father—massive, gentle, and always vanishing beneath the surface.
his life now is quiet but filled with undercurrents: grief disguised as beauty, memory disguised as motion.
to the d.m.h.o., ivo michiels is a model citizen—compliant, cooperative, peaceful.
to his students, he is a wonder.
to himself, he is still the boy who learned that even sorrow can move like water—endlessly, and without end.
hello, friends! here to present to you choi wonsik, he ironically has the most destructive potential amongst my roster yet the most controlled. he only started as a d-tier guardian recently. wonsik is actually an amalgamation of scott (cyclops) and sam (cannonball), he borrows scott’s emotional structure and sam’s desire to protect. i have a not-so tldr version of his background below the cut. additional stuff like playlist and pinterest board should be on my pinned post, if you want to have a look. as far as connections/plots goes, i prefer to brainstorm. now, if you want me to pop in your dms, just leave a heart!
born in 2002, remembered not a childhood—but a fire.
at five years old, the orphanage he lived in was destroyed when an unregistered mutagen lost control, causing an explosion that leveled the district.
pulled from the debris after six hours, barely breathing, covered in soot and blood.
the story made brief local headlines—“the boy who lived through the mutagen fire.” when the story faded, so did the sympathy.
no relatives came for him; his file was marked “no known family”.
among the dead was a volunteer and her young son—choi hyesun and the boy she’d brought to deliver supplies. her son didn’t survive.
two years later, hyesun returned—not out of healing, but haunted by the one child who lived when hers didn’t. she adopted wonsik quietly.
home life was precise, wordless, and sterile. she provided food, education, shelter—but no warmth.
she hated mutagens, yet took one in. she reminded him often: “you live because my son doesn’t. don’t waste it”.
wonsik grew up learning to move without sound, to breathe without disturbance. gratitude became a form of silence.
his ability manifested at twelve—subtle tremors under his feet, vibrations that deepened with emotion until walls cracked.
hyesun reported it within hours. d.m.h.o. classified his mutation: seismic resonance generation, the capacity to produce localized shockwaves.
containment followed. tests, gloves, stabilizers. he didn’t resist; he understood it was safer that way—for everyone.
sent to pinnacle institute at fourteen, where “control” became his only goal.
while others trained for glory, wonsik trained not to break the floor beneath them.
instructors admired his discipline, his precision, his composure under stress. peers called him detached, unreadable—“the boy who doesn’t flinch”.
he rarely spoke unless spoken to, and even then, only to clarify instructions.
graduated into d-tier guardians, specializing in containment and urban stabilization—missions that required restraint, not spectacle.
his record was spotless; zero civilian casualties, zero disciplinary marks. he followed orders like scripture.
hyesun never attended his induction, never wrote, never asked. when questioned later, she said, “he’s doing what he should”.
wonsik didn’t argue. to her, his life was a repayment plan, not a story.
to the world, he was stability incarnate. to himself, he was still a fault line waiting quietly under the surface.
hello, friends! here to present to you lee ruri, she’s a sweetheart but she’s someone you don’t want to mess with. she currently works as a park ranger. mainly inspired by shin minah’s classic portrayal of gumiho. i have a not-so tldr version of her background below the cut. additional stuff like playlist and pinterest board should be on my pinned post, if you want to have a look. as far as connections/plots goes, i prefer to brainstorm. now, if you want me to pop in your dms, just leave a heart!
born in 2000, north pyongan province, to parents who were both researchers for the mutagenic defense bureau—a department more feared than respected.
her family carried a rare hereditary mutation known as multi-sensory bio-electric physiology, a trait that blurred the line between science and myth.
her bloodline was the basis of local folklore: descendants of the gumiho—nine-tailed fox spirits said to manipulate life energy.
her powers were no myth. as a child, she could sense electrical impulses through skin, light up the air with arcs of current, and manifest semi-ethereal “tails” that shimmered like aurora threads when activated.
her parents, loyal to the regime, offered their children to the bureau’s child conditioning program—a decision made “for the nation”.
the program trained mutagenic deterrents—children raised as living weapons, conditioned to obey commands without hesitation.
lee haneul, her older brother, was protective and outspoken. his defiance marked him for harsher treatment.
ruri adapted. she smiled when told to, obeyed orders without expression, learned to make stillness look like peace.
her ability to suppress emotion became her survival tool.
the bureau ran drills in isolation tanks—days suspended in water, electrodes attached to her spine to study nerve conductivity. she learned to disassociate from her body to survive the pain.
overuse of her power led to nerve scarring and chronic bio-electric feedback, a condition that causes constant low-level pain and heightened sensory sensitivity.
at sixteen, she and haneul escaped during a transfer. he was shot multiple times shielding her near the yalu river. she made it across the frozen water, alone.
wandered through rural china for years using false names, working as a cleaner, a florist, a translator. avoided registration checkpoints. learned to disappear.
her mutation’s glow dimmed with time, her “tails” reduced to faint light trails only visible under stress.
in 2022, she surfaced in district x, south korea. registered voluntarily in d.m.h.o.
currently works as a park ranger at dream forest nature park, where she maintains trails, guides school trips, and tends to injured animals.
neighbors describe her as kind, quiet, sometimes distant. she never removes her gloves in public.
she declines interviews, cameras, and any contact from the d.m.h.o., who repeatedly offer her recruitment.
her official refusal: “i’ve done enough fighting for one country. i don’t need to do it for another”.
her record since resettlement is spotless. no incidents, no aggression, only stillness—like a storm that chose not to strike.
hello, friends! here to present to you my big softie baek “theo” taeho. formerly a c-tier guardian, now serving as an associate warden. he’s got dex (bullseye) and kaname’s precision with clint’s (hawkeye) moral compass. i have a not-so tldr version of his background below the cut. additional stuff like playlist and pinterest board should be on my pinned post, if you want to have a look. as far as connections/plots goes, i prefer to brainstorm. now, if you want me to pop in your dms, just leave a heart!
born in 1995, at the height of the guardian project’s expansion—raised not in its glory, but in its shadow.
parents, baek jinho and kang mirae, were lower-tier operatives under the d.m.h.o., specializing in logistics and containment.
their abilities—adaptive reflexes and kinetic redirection—were functional, not glamorous; useful but forgettable in a generation obsessed with spectacle.
home life was strict, almost militarized. conversations were debriefings. affection translated into training schedules and error reports.
taeho learned early that control equaled survival; emotion was a liability that could be weaponized.
his ability surfaced at eleven—superhuman accuracy, the instinctive computation of movement, distance, and probability.
could predict outcomes before they occurred; saw patterns in chaos like others saw colors.
his father tested him relentlessly—throwing knives, moving targets, ricochet drills until dawn. praise came only when he stopped missing.
mother watched quietly, never intervening; her silence became the closest thing to comfort he knew.
by the time he entered pinnacle institute (2013), he was already more weapon than boy.
at pinnacle, he stood out not for flash or strength, but for calm precision—every motion deliberate, every silence meaningful.
earned the nickname “killshot” after a perfect marksmanship streak; the name stuck even when the laughter faded.
never sought recognition—only mastery. failure was unacceptable, but victory never felt like joy, only relief.
graduated top of his class in 2018 and entered as a d-tier guardian, quickly promoted to c-tier by 2020 for near-flawless mission performance.
excelled in covert operations—espionage, assassination, suppression.
colleagues said he didn’t aim; he calculated inevitability.
earned the codename “issue” during a blackout mission where he eliminated seven hostiles using ricochet trajectories in total darkness.
from then on, “issue” became a whisper in intelligence halls—part myth, part warning.
despite his loyalty, the system he served began to rot in his eyes—bureaucracy over integrity, headlines over humanity.
retired quietly in 2023, citing “personal reasons.” few believed it.
reappeared in 2025 as associate warden of the mutagenic high-security detention center—a fortress at the edge of district x housing the city’s most volatile mutagens.
runs the prison like a silent machine; every corridor under his watch, every movement predicted before it happens.
prisoners call him “the man who sees before you move”.
staff call him sir even when he isn’t listening.
still wears the posture of a soldier—back straight, tone measured, eyes unreadable.
some say he never left the battlefield—he just built his own version of one.
