wait shoot i accidentally deleted a frame where wbc says “sorry for 4989 the inconvenience” damnit. 

anyway, a request (kinda) from deviantart, we were discussing the “inside-out” complex which is kinda like....do cells have....their own immune system? (probably not but then how do they heal up?)

Red Blood Cell, Sighted! Chapter 1

https://www.fanfiction.net/s/13022702/1/Red-Blood-Cell-Sighted

Guys...I don’t know how to say this, but I think I made a reverse harem fic for Cells at Work/Hataraku Saibou. Partially based off @lunchtimerushin​‘s beautiful fanart and my need for more neutrophil content.

U-2001 is too old for this.

If anyone were to ask him how the whole thing started, he would merely shrug, knock back a drink of barley tea, and sigh. He's not an old neutrophil, but he sure likes to stay away from the immature adventures his close colleagues like to embark on. Days for him, other than the occasional bacterium or a virus, pass by slowly while time seems to meander without much reason for worry. One would think that 2001 would have gone mad, or at the very least, bored without the lack of any activity.

That was simply not the case.

Most of the time.

"2001," U-1146 greeted casually. Like most neutrophils, 1146 was dressed in the standard uniform of a white blood cell, but he was covered head to toe in cytosol. The dark red shade contrasted starkly against the usual white color that it had 2001 recoiling in shock. Usually 1146 would have enough sense to clean himself up immediately after a mission before seeking out a friend.

2001 definitely was not expecting his colleague at all.

"1146," 2001 answered in kind. He raised a pale eyebrow, although it wasn't apparent due to his wearing of a hat. "What brings you to this marginating pool?"

Normally, 1146 would bring up a topic that could be easily answered, 2001 would offer some insight relative to the question, and they would sit in companionable silence. It was a habit that had originated back in their youth as myelocytes. Over the course of the maturation, they kept up with the tradition and it had benefited them both; for 2001, it offered a sense of companionship that he didn't always receive due to his aloof nature and as for 1146...well, 2001 hoped that his friend also received the same sense of security and friendship.

1146 seemed to frown under the visor of his hat before vaguely commenting on the state of affairs within the body.

2001, not sure how to take this unexpected turn of events, remarked that all systems within the body were doing well.

And, for a few minutes, that was that.

Until—

"The normal cells do a fine job of replicating copies of themselves," 1146 said casually. "I wonder what their lives must be like, to continuously make copies of themselves, train their copies their ways, and finally let them go. Wouldn't that make life seem so boring and fleeting?" 1146 paused before continuing. "But they also seem so close knit; they're always playing games with each other. It's admirable, honestly, given that they're usually the ones who are targeted under bacterial or viral infections."

1146 stopped. Clearly, it was the time for 2001 to say something—anything that could provide validation or add on to 1146's observation, but 2001 didn't know what to do with this information.

Normal cells? Replication? Having fun? What was his colleague insinuating?

Shrugging, 2001 murmured, "It's their job and their nature, regardless of how mundane or trivial it may seem. All cells serve purpose; you should know this. We protect and the others serve."

1146 hummed thoughtfully as he processed those words.

"And the red blood cells...carrying those packages of oxygen or carbon dioxide continuously with little to no breaks…"

Was it 2001, or was 1146 looking wistful?

"They're always running around, destination to destination with no end in sight. Do they ever truly stop? We white blood cells are permitted breaks here and there; bacterial invasions or infections are frequent, yes, but not to the point where we never stop."

"They're born to do that," 2001 shrugged as he relaxed against the vessel wall. "At the bone marrow, they're trained so that they could travel great distances without feeling tired." Really, what was 1146 getting at with this inane conversation? Truly, it was thought provoking to think about the occupations of other cells, but this was elementary. All myelocytes knew why certain progenitor cells differentiated to become monoblasts, erythroblasts, promegakaryocytes, and so on.

2001 happened to glance at 1146 at that moment.

His colleague appeared lost in thought; his eyes were furrowed and covered in shadow, his body was hunched over as he contemplated. His dead stare, which was typical of all neutrophils, seemed even more probing and blank than normal. Typical 1146 pose, atypical cause for it.

"Why are you so interested in the erythrocytes anyway?"

"Oh. I met one who kept getting lost recently. You probably saw her in that one abrasion incident."

"Hmm, yes. That incident was definitely scarring."

1146 stared deep into 2001's eyes and barked a short note of laughter. Gone was his look of contemplation; it was now replaced with his favorite companion of the neutrophil bunch.

Finally. A reaction that 2001 fully calculated and expected.

"Well, 1146, I think we should head back to work."

"Noted."

He was patrolling an area near the foot—probably the ankle if he remembered correctly—at a capillary. Here, the roads were thin and crowded with red blood cells busy delivering the oxygen to their designated recipients. As 2001 observed from a narrow passageway, he thought back to 1146's words from earlier.

From an objective standpoint, it made sense that immune cells were allowed to have breaks every once in a while. They expended incredible amounts of energy defeating bacteria; therefore, they needed time to regroup and refresh. On the other hand, red blood cells ran around all the time, but they were trained to endure. They could withstand resistance longer and were allowed to walk on their way back on the circuit back to the lungs. For practical reasons, it made sense; different jobs yielded different needs.

So deep in thought he was, that he was completely blindsided when he heard a sudden crash and several curses from a group of passing red blood cells. Even though this situation could have been handled by others, he casually strolled from his hiding spot to see if there was any trouble. It appeared that one red blood cell (one with brilliantly red hair befitting of her cell type) had mistakenly bumped into another red blood cell (this one not as ostentatiously colored or differentiated). The situation looked like the red blood cells could deal with affairs within their circle (the redhead was already apologizing and gathering up the boxes of oxygen) so 2001 merely shrugged and moved back.

For several minutes, 2001 contented himself with his thoughts while he passively observed the red blood cells and a few platelets walking or running to their destinations. One of those who were running was a red blood cell (the very same who was the inciting incident for that accidental crash) who walked past him. Nothing interesting.

Well that in itself wasn't interesting until he saw that the clumsy red blood cell had walked past him again.

And again.

And...again.

After seeing that the red haired erythrocyte had passed by his hiding spot twenty-two times in a span of fifteen minutes, 2001 decided to step in.

Literally.

On the twenty third attempt, the erythrocyte had neglected to tighten her shoelaces. The result was, and this should have been obvious, was halfway disheartening to any aspiring red blood cell.

The scene was halfway disheartening because 2001 didn't want any cells under his watch to end up getting hurt—even if it was her own undoing.

Due to his quick reflexes and ideal spot, 2001 managed to grab her by the back of her shoulders and righted her up in record timing. For a moment, her eyes were dazed and confused; her mouth gaped open in a shrill scream that had 2001 wincing because of the pitch and frequency. Heavens above, such a sound at such punishing decibels shouldn't have been possible. However, she quickly turned to him and began apologizing—all of which he managed to deflect with the proper "oh's" and "mm-hhms".

"—orry, Mr. Neutrophil! I didn't—I mean, I'm kind of clumsy and I'm still trying to learn all my routes and—"

2001 held up a hand, which immediately quieted the red blood cell.

"Turn left on the main road and go straight for 100 micrometers. There, you'll see a checkpoint that has a reliable map and plenty of red blood cells who could help you." After observing the package of carbon dioxide that the red blood cell was carrying in her arms, he immediately deduced that her next destination was for the lungs.

Gobsmacked, the erythrocyte looked from the main road to 2001 and back. Was she dreaming? Was another neutrophil helping her out? Were all immune cells this nice?

Gratefully, she bowed again and thanked him graciously. However, when there was no reply, she found that he was no longer there. A little confused, but still overly grateful, she saluted the deserted area and headed off the main road. For now, she was content that she was back on track.

She hoped that she would find that kind, aloof neutrophil again in the future.

U-2001 couldn't help but...soften at the sight of the red blood cell saluting and then leaving with a smile so bright, that it could rival that of Dendritic Cell's. It wasn't every day that 2001 managed to see such a happy smiling cell in person. It was rare that cells would approach him, rarer still to see one so willing to thank him for such a trivial action.

Was it a habit of red blood cells to be so emotional and helpful?

Or was it just a trait of this particular red blood cell?

Briefly entertained with this thought, 2001 idled away until he heard his transceiver inform him that help was needed elsewhere.

This time, it was 2001 who approached his friend 1146 in a marginating pool. After the usual greeting and pleasantries, they lapsed back into silence. Again, the atmosphere felt safe and companionable; a far cry from the heat of battle and the call of bloodlust. It was soothing and for once, 2001 relaxed and let his back touch the wall of the blood vessel, fully at ease and a micrometer away from taking a nap, germs be damned.

"Something good happened today," 1146 commented as he watched his colleague sag against the wall in uncharacteristic tiredness.

Not a question; it was an observation.

"Depends on perspective."

"Then let me rephrase, from your perspective, did something good happen?"

2001 could have said anything. He could have said that he had a quiet time patrolling the foot. He could have said that he spent his entire patrol philosophizing and that he came across some great discovery before it disappeared like plasma. He could have said that his day was relatively peaceful other than that allergen that happened to run amok. If this were any other day, he would have said any of the above, but for some odd reason, images of a sweet smiling red blood cell who looked so earnest and trusting made him want to-to—

"I stopped a red blood cell from tripping." 2001 stared resolutely forward—no, he wasn't avoiding his companion's eyes. "It was all in a good day's work, I suppose."

Even without looking at his right, 2001 knew that 1146 was staring disbelievingly at him. Looking back, 2001 knew that this was a weak way to explain the feelings that were circulating throughout his nucleus. But really, what could he say? It wasn't a particularly big achievement or anything worth remembering. Heck, the only reason he remembered the event was because it was jarring to be thanked so honestly and with such vigor.

"It's our job to help all cells, regardless of circumstances." 2001 tried to justify. " If it was a platelet, you would do the same. It's our job."

1146 hummed in assent.

2001 could hear an underlying current of sarcasm, but he didn't mind. After all, he technically wasn't lying.

After a while, they said their goodbyes and left the marginating pool together before going their separate ways. Like any other meeting with his fellow white blood cell, 2001 was left with a sense of...not exactly loneliness, but an awareness that once again, he was alone with only his thoughts to keep him company.

On most days he was quite all right with that.

Today...today, he felt too old, too tired to be alone.

[heckthis-heckallofthis]

I thought it was 2048 kicking his teacher while 4989 was going just as wild as 1146 on the costume? X D Either way 2626 proves once again he's carrying the only brain cell in the group.

He stole all of their brain cells the moment they were born and never gave them back, he would give them back to 46 but once 3803 was in the picture he decided to keep them for just a bit longer

[lazyflan]

Since it's canon 4989 is a chaotic cell yet he showed a more gentle and sensitive side with 3803, I personally hc he acts like a perfect gentleman with 3803. When she's gone, he's back to being a wild child with a dangerous temper. 1146 is both grateful and annoyed. X D

OMG YES!!!! He gives me the same vibe as those friends that your parents love but when the adults/parents aren’t around they just go wild???? Like, I feel that at one point 1146 is gonna complain about him and 3803 will just go ??? what do you mean??? he is such a gentleman???? and be completely confused

[shiny-armin]

I saw the ending scene. It was really cute how embarrassed 1146 was to admit he got stepped on by BK and 4989 kept teasing him when 3803 wasn't buying his excuses. It's also funny how much 1146 does adore 3803 a ton but he can tell he has a easier time opening up to his friends or the Platelets about his feelings then he does her. She makes him so flustered by how perceptive she really is over him. I bet he always wants this certain tough image of him to be in her mind while she's just sees him-

2 as a sweet helpful guy who's dependable but otherwise normal. X D 1146 is totally twice shy with her while she's just so easygoing by comparison (1146 get a handle on your crush already). I also thought the moment between 4989 and 3803 was totally wholesome and they need to be shown being bros more. I could totally see them being sibling like and 4989 teasing 1146 about 3803 like crazy while she's oblivious or cool about it (but gets on him if he's too sassy about it).

3.  1146 to 3803 can be both totally overprotective and think she can handle anything like a champ at the same time and that's so sweet of his dynamic with her. Meanwhile she can read him like a book and understand how he works just as good or even better then his best friends. Ugh, these two slay me with feelings. Relationship goals that bring life (literally). Lets not forget, it's canon that the image of 3803 that exists inside 1146's mind is her cute adorable face smiling and blushing and making only happy faces. 1146 has a type. The type is only 3803.

4. The way 1146 killed that germ in S2 so 1 came off as pretty funny to me. The germ went from thinking 1146 is bonkers to respecting him as he died. That animation of 1146 jumping up and down on the germ like he was a trampoline made me want to laugh for some reason. Bonkers 1146 is my favorite way to describe 1146 in kill mode now. X D Also it's pretty cute how 1146 goes from trying to be heartless to so soft he almost kills over from it. I appreciate it's canon 3803 is definitely his only type.

I definitely see him way more embarrassed in the anime than in the manga. I was literally crying from laughter when he was cheering for BK but still was very worried for her, and 1146 started stuttering/yelling for a second and I lost it poor man. I loved how he noticed how brave and prepared 3803 had become! Just tell her to her face coward. And of course, 3803 and 4989 interacting made me squeal, I love this stupid family!! Tho I’m starting to see people shipping them, which is also cool!! But my poor boy 1146, 4989 has definitely got better way of words than him.

Honestly two cells having a very healthy (platonic/romantic) relationship makes me lose my mind in the good way. It’s one of the most balanced I’ve seen in anime, and I’ve watched many lol. Many could think 3803 is a damsel in distressed, always being saved by this giant dog guardian... But the truth is she is always saving her ass at the end of the day, while 1146 just keeps.. you know, bodyguarding from a distance. But that’s only because he wants to, she can take care of herself.

OMFG 1146 has a type lol. It’s true he’s like... extra fond of cute things. He’s too sweet. 

YES I ALSO LAUGHED when he started jumping like what was that for lmao ToT In the manga it looks like he’s only T-posing to assert dominance but what in fresh hell. It’s also funny how he can manage to switch between attitudes with that ease, especially him being a very serious and stern guy. He starts off the episode with his eyes bloodshot and ends it flustered and pouting because some platelet stepped on his face and his crush is near him, lol.

Neutrophil Squad with S/O Headcanons

Warnings: Slight fluff, slight angst, death mentions, etc.

@quinn-marie1213 Request: Do you have any headcanons for the neutrophil squad and their respective S/Os

.

.

.

U-1146 with an Immune Cell S/O

Like most of his relationships, his relationship with his S/O is going to start out in the most professional way possible. Perhaps they’ll meet during a mission, a break in between killing pathogens, or maybe in the bone marrow as sparring partners. Whatever the case, his falling for his S/O takes an absurdly long time.

Confronting and telling his S/O about his feelings takes even longer.

So, if 1146 wants to have a relationship with his S/O that isn’t professional, he’s either going to take forever to pursue a romantic relationship or maybe his S/O will be far more courageous.

When 1146 actually starts his courtship, he’ll be bashful at first, but then he’ll start to become more outgoing. He’ll make sure to take his S/O out to the most scenic areas within the body and spend calming walks with cups of tea in their hands.

As for missions, he doesn’t mind if their schedules don’t match up. Since his S/O is an immune cell, he knows what hardships they’ll go through and what it takes to survive. That said, he’ll worry after the dust settles, but in the thick of battle, he has faith that his loved one will be okay.

The thought that his S/O may die while defending the body doesn’t cross his mind that often. Trust and loyalty are things that he doesn’t offer freely so to think that he’ll desecrate his S/O’s abilities by thinking that they might fail… It’s in his nature to think the best of others, that they’re always improving.

U-1146 with a Civilian Cell S/O

Let’s face it, 1146 is going to find his S/O when he’s busy defending them. He’s far too serious and too conservative to seek out civilians on his own, so their first meeting is when 1146 is going to be out on the hunt.

Furthermore, his S/O will either have to be persistent in trying to find 1146 just to talk to him or perhaps a series of coincidences and happenstance will have to make sure that he and his S/O will meet up again. Either way, it will be hard to get a hold of 1146 at the very beginning.

However, once he and his S/O establish a friendship, that’s when he’ll start to grow feelings bordering on romance. Since this is a civilian S/O, he’ll naturally feel curious about his S/O’s work.

What do they do? How can they do it with such ease? As an immune cell, he isn’t privy to having a break that isn’t prefaced with looking over his shoulder every couple seconds in case an attack occurs. He’ll find that the more time he spends with his S/O, the more likely it is for him to relax.

He worries over his S/O from time to time, but he manages to train them to always run away and seek cover in the case of an attack. His S/O dying is something that he would rather not entertain, but even he is realistic about this scenario.

General Headcanons with U-1146

Tea. He’ll make his S/O lots of tea. Doesn’t matter if you’re having a great day or a bad day, tea will always be provided.

He doesn’t sing that often, but if his S/O is willing to duet with him or be subjected to a private serenade… Well, he’s not fully enjoying himself because singing isn’t his passion, but he does feel happy when his S/O lights up whenever he sings their favorite song.

He likes to take long walks around the body once he and his S/O’s schedules line up.

U-2001 with an Immune Cell S/O

This man isn’t all too interested in romantic or sexual pursuits. However, if he does try to go through with this endeavor, more likely than not, his reasoning for it will stem from mutual respect. He’s a competent and calm cell by nature—quite like U-1146 in this respect—but he isn’t as foolish or as slow to act like him. If 2001 knows that he has feelings for a potential S/O, he will be rather blunt and quick about it.

If he’s rejected, so be it. If he’s allowed into his S/O’s life, then there’s that.

Once he’s established a relationship, it won’t seem like anything has changed. To anyone observing on the outside, they probably don’t notice that 2001 and his S/O are in a relationship. However, behind the scenes, 2001 seeks out stimulating conversation and even physical affection.

U-2001 with a Civilian Cell S/O

He is one of the most elusive of the WBC squad. Although he works amiably alongside civilian cells in the body, he doesn’t take time out of his day to actually seek out the presence of civilians. He’s just as professional as 1146, but he lacks the endearing cuteness that he has.

However, what 2001 lacks for in warmth, he makes up for in devotion and loyalty.

2001 likes to walk his S/O to and from work, often parting with a quick, but loving farewell. He’ll use this time to pay attention to his S/O’s interests and perhaps suggest an outing after work or surprise them with a gift that they’ve been wanting.

General Headcanons with U-2001

Deep down inside, 2001 is basically an old man. Therefore, if he isn’t on patrols, his S/O can find him reading in cafes around the body or lounging in the marginating pools. This is the time where his S/O can cuddle up to him.

2001 is also fond of ruffling his S/O’s hair. Honestly, he’ll make it a game where he’ll take the cap off their head while they’re not noticing, ruffle it until their hair ends up like a bird’s nest, and then gently slap the hat back on their head. The messier and more ruffled his S/O looks, the brighter his smile.

He prefers comfortable silences with his S/O. He’s a man of few words, so it’s through his actions that he’ll display his love for his S/O. He’ll more than often communicate with gestures like a brush of the shoulder, a kiss on the brow, and the final squeeze of their hands before letting go.

2001 will never admit this, he has a soft spot for sweets. If his S/O should be so inclined, then they can easily have him wrapped around their finger.

U-2048 with an Immune Cell S/O

For the most part, if his S/O is an immune cell, it probably didn’t start out too well. Despite the fact that he has come a long way from his days as a myelocyte, he is still somewhat insecure and anxious about his capabilities to be a great immune cell. Because of that, it only stands to reason that he may posture too much in his S/O’s presence before an established relationship or he may envy his S/O’s abilities if they surpass his own.

However, once there is a breakthrough—perhaps they are sent on a mission together, they save the other’s life time and time again, etc.—they slowly start to warm up to each other. If 2048 can get over his insecurities and if his S/O gives him enough time to make sure that he takes this relationship seriously, then it would work.

In a relationship, 2048 likes to think himself suave and flirtatious. Turns out, one smile or a cheeky little quip from his S/O could turn him into a puddle of cytoplasm. However, that isn’t to say 2048 isn’t capable of both giving and receiving affections.

He’ll bring his S/O gifts. Anything that they’ll like, anything that looks pretty or something that could suit his S/O’s features, he will make sure that his S/O gets it.

He truly believes that his S/O deserves the world.

Out of the rest of the WBC squad, he is one of the most heavily devastated if his S/O dies in the line of duty. Although he may have resolved most of his issues once he established a relationship with his S/O, he may still be reserved when it comes to admitting his affections. If his S/O dies too soon, then he’ll spend countless cycles wondering if he should have said that he cared more, done more, acted like he cared more.

He’s never truly the same if the inevitable happens.

U-2048 with a Civilian Cell S/O

It’s a bit funny, he supposes, that he might find the civilian cells interesting. He’s not too popular with the platelets (or any of the civilians, to be honest), but he does have a duty to the body. In the midst of a battle or during the post recovery efforts after an invasion, perhaps he’ll stay behind and make sure that the victims are taken care of.

Or maybe one of the victims takes care of him.

Either way, 2048 and his S/O meet while he’s on the field and they’re subjected—quite early on—to what it would be like to hang out with 2048. He can be proud, standoffish, possibly overcompensating for something with the way he acts, but he can also be caring and devoted. Even though he may not know how to deal with a civilian’s stress or tears, he will make sure that his charge is well taken care of.

2048 may be rather curious and forthcoming in his efforts to find his S/O again after his initial meeting. After all, he wants to find out if his attempts to make sure that his efforts at comfort were worth something, you know? It’s not like he cares more than that… (Spoiler alert: he slowly becomes more and more caring).

Meetings become more and more frequent, meetings become outings, outings into something more.

A relationship is formed and 2048, for once, seems whole and complete. He doesn’t have to prove something if he doesn’t have to.

But—

If his S/O dies while in battle or during an attack… It’s all over and he just might retreat into himself. What’s the point of becoming secure and more honest with oneself if it’s all taken away because the nature of the body is to be cruel on a whim?

General Headcanons with U-2048

He is a bit of a show off. If his S/O is caught off guard, then it’ll be easy for 2048 to sweep them off his feet. However, his S/O isn’t simply just his S/O because it would be easy. No, 2048 actually likes it when his S/O trips him up from time to time, giving him a taste of his own medicine.

2048 likes to think himself suave and one of the more handsome cells in the body, but he’s quick to worship his S/O. If someone so much as thinks his S/O isn’t that attractive, he’ll definitely get on the offender’s case and will reassure his S/O in the same breath.

Tease him. Keep him humble. His S/O will marvel at how cute he looks when his normally white pallor becomes flush with a bright red hue.

U-2626 with an Immune Cell S/O

If he’s not out fighting, he’s an on-call medic with abilities that rival that of a macrophage. So, if he comes across a particularly attractive immune cell who just so happens to be wounded, he’ll patch them up and see them on their way.

And, perhaps, the story about 2626 and his S/O might end there, but it simply doesn’t.

2626 has a way with words, a presence that most would take for granted, but some would find refreshing like a fresh glass of water. When he treats his patients (aside from scolding 1146), he can be calm and authoritative, always knowing what to say and how to say it.

And perhaps… it’s more than likely that it’s his S/O who seeks him out.

Accidents and injuries aren’t unheard of, but the rate of injury—just for you!—it’s almost remarkable. Pretty soon, 2626 knows to expect you more times than not and because he’s more in tune with your presence, he becomes more and more frantic about your state.

Soon, he basically calls himself your personal medic and gives you advice on how to keep yourself from injury. Eventually, though, 2626 and his S/O start meeting outside of the battlefield and that’s when 2626 starts realizing that maybe… just maybe… his S/O wanted to meet with him because he is genuinely a good person.

It’s a shocking discovery for 2626, but he does end up teasing his S/O for it later on in their relationship.

If his S/O dies while defending the body, he’ll be quiet and withdrawn. He’s not exactly resigned to the idea, but he does know that one day injuries can’t be healed, bodies can’t be so easily restored.

Sometimes, cell bodies will take a hit too deep, scarring is no longer an option… and it’s time to say goodbye.

2626 will move on, but his heart aches a little every time he treats a cell who might share a trait with his S/O.

U-2626 with a Civilian Cell S/O

To be frank, 2626 doesn’t know if he has medical jurisdiction over civilian cells. Well, management hasn’t said anything about it and civilians haven’t complained about his methods, so he’s going to assume that this civilian is more than likely his responsibility for the time being.

Or, perhaps he’ll meet them while he’s out playing with the platelets or hanging around some of the scenic locations in the body.

Whatever the case, 2626, is very kind and caring towards them. He also understands that a lot of civilian cells aren’t too comfortable with the immune system and that it may take time for them to become used to him.

He’s loyal, but he’s also very persistent.

He’ll be good friends with his S/O and make sure that they’re comfortable. After spending so much time with his crew, it’s safe to say that he has a lot of humorous stories to tell, jokes to recount, and a lot of secret passages and forgotten paths to exploit so that he can entertain his S/O.

Like with his immune cell S/O, death is inevitable. However, he also knows that since his S/O isn’t an immune cell, their death should be avoidable at the very least. It’s one thing to know that his S/O will die once they outlive their usefulness to the body, quite another to realize that they died while he was on duty.

He’s a worrier and a mother-er at his core. If he suspects that there is anything wrong with his S/O, he will do anything in his power to provide for them and make sure that they are whole and whole—physically and mentally. (His S/O shouldn’t be surprised if he starts throwing gauze, bandages, and ointments around if there is anything amiss).

He’s also a great shoulder to cry on. Seriously, his shoulder isn’t bony at all and if his S/O rests themself on him, he’ll run his fingers up and down their back, against his scalp, and kiss their brow if need be.

He can be a bit of a prankster. If his S/O thinks that he’s hiding something or it may seem that he’s being too quiet… It's probably because he’s going to surprise them with something romantic or something horribly funny.

Brushing his bangs aside is a special treat because A) his S/O will realize just how fluffy his hair is and B) they will see how wide, expressive, and beautiful his eyes are.

U-4989 with an Immune Cell S/O

4989 may or may not have permanently borrowed his S/O’s standard issue equipment at one point. Or may have interrupted an intense climax during battle only to wave around a tray of steamed buns in front of both ally and enemy eyes.

To put it simply, 4989 makes a name for himself. Management and administration takes notice and so does his S/O. 4989 can be a bit flighty, but that’s all right with his S/O. It’s easy to track down 4989 he has an impressive track record floating the rules concerning weaponry, equipment, and the customization of contraband items.

Once he and his S/O meet, he’s also curious about them as well. What kind of cell would seek him out? That starts a conversation between the two of them and pretty soon, 4989 invites his S/O out on missions so they can see his inventions in action. (And if his S/O wants to start helping or creating their own contraptions then he’s not going to judge. He will, however, smile proudly).

In the end, both his S/O and himself become a bacterium’s worst nightmare.

As the youngest member in the squad, it’s hard for him to truly grasp what death is like. Sure, he’s a killer and he has known many veterans to commit apoptosis when they’re too old or give out in the midst of battle, but he doesn’t know how to describe how he feels when it’s his S/O’s fate to die. Could he have done something to help prevent their death? An invention that could have catapulted that bacterium off their back? A contraption that would have served as a great distraction? It haunts him and if he cuts back on inventing new weapons for a few cycles, no one really questions it.

U-4989 with a Civilian Cell S/O

When the higher ups realized that 4989 had stolen and abused your trays of steamed buns to defend the body, they were more than pissed. They were pissed because 4989 had flouted their orders once again. They were embarrassed because it seemed like they didn’t have the funding to equip their immune cells with the proper weapons and gadgets. And they were determined to get it through his nucleus that he couldn’t simply take and modify any sort of equipment from any cell—especially that of civilian cells.

So when his S/O finds out that an immune cell has been forced into community service for a couple cycles, it’s a bit jarring to say the least. True, it was weird to find out that the reason why they were short on steamed buns was because an immune cell had seen fit to use it for defense. It intrigues his S/O, so while 4989 is enlisted in service, his S/O begins to strike up conversation. First, out of curiosity, but then…

They both want to learn more about each other.

At first, 4989 indulges in his S/O about all of his inventions, ways to get around management, and being an all around fun guy, but then they start to connect on a deeper level. Once his S/O starts rooting underneath the surface, 4989 practically becomes putty for them.

And once he’s become putty… he’s practically head over heels for them.

He’ll sneak them away for different outings around the body and regale them with stories about his squad.

As for death, he simply doesn’t want to think about it. Childishly, he knows that it’s always possible: endothelial cells could crumble, bacteria wilts, and the body is a volatile environment at times. At best, he’ll spend what time he can with his S/O, trying to memorize their laughter, smile, and whatever else he likes most about them.

General Headcanons with U-4989

This man will literally do anything to make his S/O happy. Administration, management, the higher ups? Doesn’t matter. He’s already probably on their blacklist anyways, so what’s more non-issue, non-standard tinkering with a regulation weapon or item? (Yes, he will make stupid inventions just to watch his S/O laugh and smile at the sheer ridiculousness of it all).

He’s a bit of a crybaby underneath his immune cell exterior, so his S/O should always have a couple of handkerchiefs on hand to wipe his tears. His S/O should also be understanding and willing to help him through moments of weakness as well.

Please ruffle his hair. And pat his cheeks. And nuzzle his nose. Physical affection is main love language and he will swear that his S/O giving him love is ten times as healing as 2626’s medical care.
