Giyu hides his jealousy way too well. You two had worked together for a very long time. The first few months of knowing him you didn’t even know if he knew your name let alone that you existed to him. He was not very open so you left him alone the best you could. That was until one day you were eating peacefully and he came and sat next to you. You were stunned, your chewing paused as you slowly looked over at him. He was sitting cross legged beside you, quietly opening his wrapped food. When he noticed you looking he paused and met your eyes.

“Hm?” He hummed, as though he sat next to you all the time. As though you two had said more than three words to each other in months. You didn’t want to scare him off so you just gently shook your head. 

“Nothing.” You answered, looking back down at your food, swallowing nervously. Giyu returned his look to his food and out of the corner of your eyes you saw him pause. 

“Are you… friendly with Sanemi?” He asked. You furrowed your brow, chancing a glance at him. He met your eyes with a curious stare. 

“Sanemi?” You repeated. He nodded his head once. You purse your lips. You were friendly with all the hashira’s except him but you didn’t think that was exactly what he was asking. Well to be honest you weren’t really sure what he was asking so you decided to play it safe.

“Hmm… yes. He’s a friend.” You answer. His face doesn’t reveal anything as he nods his head again, looking back at his food. You wonder if you answered correctly as he suddenly pulls out a little white sweets box. The very same sweets that you would buy as a treat for yourself after missions. 

“Just a friend?” He asks as you nod your head, blushing slightly. Giyu looks relieved and hands the sweets over to you without a word. 

“Oh… for me?” You ask and he nods his head. When you reach to take it your hands brush and you swear his cheeks pinken.

You didn’t think Mitsuri ever got jealous until a few years into your relationship. You two often had missions together which meant you also had time off at the same time. Hiking to the swordsmith village to relax. After settling in you two hit the kitchen. The only thing that could rival your love for each other was your love for food. There were a few other hashira’s around and when you couldn’t pop a jar open you handed it over, sighing, to the closest person, which wasn’t your girlfriend. Shinobu popped it open for you and you continued to help prep the food. That’s when you noticed Mitsuri pouting and when you met her eyes she blushed and looked away embarrassed, returning to helping prepare food. You didn’t think much about it but at dinner she was quiet. You wanted to ask if something was wrong but you didn’t want to embarrass her in front of the other hashira’s so you waited until you two were headed back to your shared cabin. Once out of ear shot you reached and tucked her hair behind her ear so you were able to see her face. 

“Is something wrong?” You asked, still blushing she shrugged it off, shaking her head.

“No… nothing’s wrong, dear.” She answered quickly. It was an obvious lie.

“Did someone say something to you? To make you upset?”

“No… it’s… nothing important.” She said with a soft shake of her head, like she was trying to trick herself into forgetting about it. You laced your fingers with hers. 

“If you're upset then it’s important. Come on, just tell me.” You prodded gently. She gave a little sigh and you could tell she was a little embarrassed but still she opened up to you.

“I’m strong… you know,” She starts, wearily looking over at you.

“I know that.” 

“I can open things. Lift things…. You know, you don’t need anyone else to do that kind of stuff.” Slowly you nodded your head, trying to understand what she was saying. “I just wanted you to know that.” You gave her hand a gentle squeeze and that’s when it hit you. You absentmindedly let someone open a jar for you. It really was a small thing but you knew Mitsuri liked to be strong for you. You turned to hide your smile, you pulled her hand to your lips and kissed her knuckles. “That… reminds me, honey, I’m exhausted…” “You want me to carry you?” She asks excitedly as you softly laughed, nodding your head. MItsuri sweeps you off your feet with ease and you can tell she’s forgotten all about being upset.

Obanai doesn’t necessarily get jealous, it's more of a territorial thing. You thought for sure he hated you, little did you know he worshiped you from the start. Sometimes you’d have missions with him and he'd speak about three words to you and sometimes when you were lucky he’d speak full sentences. You didn’t know until later on it was because he was so damn nervous around you. On this particular mission, after slaying the demon, you two went out for drinks. It was wholly awkward so you excused yourself from the table and found your way to the bar. The bartender thanked you for helping with the demon and it felt nice to talk with someone. This whole thing played out for maybe two minutes before the bartender froze, eyes fearful as he glanced behind you. You furrowed your brows and turned as Obanai approached. 

“We received another mission, we should get going.” He says as you sigh, nodding your head, he placed some money on the counter for your drinks.

“T-the drinks are on the house.” The bartender offered but Obanai just slid the money over, his eyes sharpening. You watched the whole thing, sort of speechless. When you followed him out he held the door open for you and gave one more heated glance at the bartender. The village you two were currently stationed at was quiet and peaceful. 

“Where are we headed next?” You asked as you fell into step with him.

“A few towns over.” He answered and you nodded your head, knowing that was just about as much talking you're probably getting out of him tonight. “Unless you wanted to stay.” 

“Stay here?” You asked, he was walking a few steps ahead of you. He didn’t answer. “I wouldn’t have minded having a few more drinks.” You joked.

“With that bartender?” He added and you didn’t miss the bitterness in his voice. You paused, deciding whatever you said next you had to tread lightly. You could tease him or you could clear things up. 

“At least he talks to me.” You said. He stopped, turning to face you.

“Anything enlightening?” 

“Wouldn’t you like to know.” You said and he raised his head just slightly.

“I would.”

“I’m joking, he was just thanking us for taking care of that demon.” You said truthfully as Obanai nodded his head, turning away from you as you walked. You didn’t want the conversation to end. Even though you two never talked much before you found yourself wanting to hear more of his voice, wanting more of his attention. Unwittingly you had all of his attention most of the time. You couldn’t think of anything to say.

“You make me nervous,” Obanai says over his shoulder. “That’s why I don’t talk much.”

“Oh,” You were stunned. He turned to face you again and you gave him a soft smile, you wanted him to feel comfortable with you. “Is it because I talk too much?” You ask. Obanai instantly shakes his head ‘no’. 

“Don’t stop. I like the sound of your voice.” It almost sounded like a plea.

Sanemi lets it be known he’s jealous, he doesn’t care to hide it. Someone’s talking with you, smiling and laughing a bit too much with you? There’s Sanemi saddling up beside you, hand sliding around you to rest on your hip as he pulls you a bit closer to him. He’s shameless. When he first met you, you were in training to be a hashira under Tengen and Sanemi would watch your workouts sometimes. He’d always watch with this sort of intense expression and sometimes it caught you off guard and distracted you. In those moments Tengen would take you to the floor, huffing. 

“I’m going to ban him from our training sessions if you can’t focus.” Tengen said, he straddled you, pressing you into the dirt as you cleared your throat.

“I’m so sorry sir, it won’t happen again.” And at least for the rest of practice that day you kept your eyes on your teacher. But after Tengen was finished with you he ruffled your hair.

“You’re a force to be reckoned with if you keep your eyes off the wind hashira.” He said and you turned bright red, unable to chirp back at him so he laughs heartily and waves as he leaves. You sigh, turning as Sanemi grabs a practice sword. You watch as he swings it around before pointing it towards you. 

“Tengen’s a handsy guy. Already has three wives but watch out and you’ll be his fourth.” Sanemi stated dryly. You were exhausted from training and the way Sanemi moved closer to you you wondered if he was wanting to train you a bit himself. Sanemi circles you like a predator. You feel his eyes on every part of your body as you swallow dryly. When he walked back around the front he tossed you the sword and you caught it with ease. He grabbed a sword himself. 

“I… am exhausted, Sanemi.” You huffed and he gave you a heated look. 

“One round.” He points the tip at you. You swallowed down a sigh and pointed your sword right back at him. You weren’t bad by any means but you weren’t even close to the level of a hashira. Sanemi worked around your blade with practiced ease and you realized right there and then that Tengen was certainly going easy on you because Sanemi had backed you up in seconds and took you to the ground. He pressed himself against you, his sword against your neck. Your eyes glared up at him.

“Alright you won, can I go rest now?”

“Has that lousy sound hashira taught you anything?” Sanemi questions. He was obsessed with this. He saw the look on your face. “Ditch him, I’ll teach you from now on.”

“I’m not doing that. Tengen is a good teacher.” You defended. Sanemi pulled the sword away from your neck and with swiftness pulled you to your feet. He doesn’t let go of your hand though and the closeness to him has your heart beating wildly in your chest. 

“I’m better.” He says as though it's a well known fact. You wondered what his motives were and what his grudge was against Tengen. 

“What’s this about?” You ask and watch his eyes leave yours as he shamelessly looks at your lips, scanning what he wanted to before meeting your eyes again. This simple act wreaked havoc on your systems. 

“I think it’s pretty clear, I want to teach you myself.”

“Why though?”

“Tengen doesn’t deserve to. That’s why.” He pulls you to him suddenly. “Do you understand?” His voice was low and soft, eyes searching. He was trying to tell you something with his eyes. He sighed, you guessed he needed to be more clear with his intentions so he gave a small shake of the head and dipped his head to meet your lips with his. You sucked in a breath as he kissed you hard enough to prove his point. You understood now, albeit a little late.

Rengoku’s jealousy is healthy. He trusts you fully but doesn’t trust anyone who would come up and flirt with you when he’s right there. A lot of people come up and talk with you and you're completely oblivious to their flirting so Rengoku will intervene to save you. On your very first date the waiter at the noodle place you two were at flirted with you practically the entire time. Rengoku didn’t get angry, in fact it made him smile that no matter how much flirting was being done you’d still be leaving this restaurant with him. But the moment the waiter stepped over the line and made you clearly uncomfortable Rengoku cleared his throat. He didn’t yell or make a scene, he just simply gave the waiter a fiery glare. The waiter was gone within seconds. You looked at your date, giving him a knowing and thankful smile. 

The only time jealousy fully got under his skin was when he came back from a long mission and caught sight of you eating lunch in the courtyard with Giyu. He felt his cheeks burn at the sight. One thing Rengoku loved just slightly less than you was food. And what he loved more about it was eating it next to you. But here you were, eating it next to someone else. Sure it was childish but logic never really came into play when jealousy took over. When you walked back to your shared room and caught sight of his red hair your face completely morphed into light as you sprinted across the room and slammed against him in a bone crushing hug. He’d been gone for at least two months and it was almost unbearable.Rengoku, despite pouting slightly, wrapped you in a hug with the same vigor, breathing in your scent. You two stayed like that for a long moment. 

“I missed you. When did you get back?” You asked, muffled against his chest.

“About an hour ago.” You pulled back at that, looking up at him. He wanted to mope but the moment your eyes met his smile so wide fitted to his lips. 

“An hour?” You asked. “Why didn’t you come find me?”

“I saw you eating with Giyu, just didn’t want to bother you.” He says and knows he was being silly earlier. But being apart from you for two months had made him weary and heartsick for you. 

“You could never bother me. Never.” You doubled down, pulling his face to yours, proving your point with a kiss. He mumbled an apology against your lips before you smiled into the kiss. When you pulled back you slightly smirked up at him. “Was that jealousy?” You asked as his entire face went beet red and you knew you were right. You tilted your head to the side. “Kyojuro…”

“I’m sorry,” He says, tightening his hold around you. “We’ve been apart far too long.”

-

Tengen also hides his jealousy pretty well but hides it behind jokes. You could not stand him when you first met. You were nothing like him. Liked the quiet, liked the dark, liked your solitude. Tengen on the hand liked you. He liked how quiet you were and wanted to diminish the dark for you and snatch away your solitude. You liked your personal space and he also liked your personal space. 

You grew up an only child with cold parents in a depressing town so when you met Tengen and he was flashy and warm, naturally you sulked away from him. He tried everything. He bought you your favorite sweets and relished when you’d give him the smallest of smiles that looked more like a grimace but he’d take what he can get. He’d find you books to read and insist that you read it to him in return and when you begrudgingly agreed he’d melt into a puddle and sit as close as humanly possible. And when he’d pretend to fall asleep on your shoulder he really felt as though he could combust. 

He’d never chased after someone so hard. 

You were so elusive, just out of reach. When you met his wives they all adored you in the same way he did. It scared him though, you weren’t one to put yourself out there. You didn’t like many people and being with Tengen meant you’d be with four people at all times. Though the times that you were around and happened to run into him and his wives you didn’t seem overwhelmed. In fact the first time he saw you actually smile, like eyes crinkling cheeks blushing smile was when Hinatsuru pulled you into a hug and told you how pretty you looked. The only jealousy he felt then and there was not being able to have that smile directed at him. But after seeing that smile he finally realized it was possible to make you smile so let the teasing begin. Suddenly Tengen was around all the time. You didn’t notice it at first but suddenly he was everywhere. Teasing you, overtly flirting with you, towering over you and trying so damn hard to make you blush and smile the way his wife did. 

It was exhausting for you. All this attention. What was even more exhausting is pretending that you didn’t want Tengen. There was a war within you. Wanting to be alone and wishing to never be alone again. Tengen and his life was the polar opposite of yours. Everything you couldn’t stand but found wanting to tolerate, wanting that shine in your darkness. Things all came to a head when you were at a fork in the road. Tagging along Tengen’s mission versus Giyu’s. To you it was an obvious choice. Tagging along with Giyu meant not really having to talk the entire time. And when you told Tengen things spiraled.

“So you got a thing for the quiet ones? Should’ve known.” He teased with this sort of practiced ease. He looked wholly unaffected by your decision.

“I don’t have a thing for anyone.” You corrected, you had been cleaning your katana when he found his way into your room somehow without your objections. Maybe it was all the time that you were spending with him things were just slowly becoming comfortable? 

“You’re breaking my heart, sunshine.” If looks could kill Tengen would be long long dead. It wasn’t the first time he called you that nickname and it certainly would not be the last. Unfortunately.

“I’m very busy, you know.”

“Busy thinking of your mission with the stoic Giyu?” He teased and you breathed in and let out a huff of air.

“You are relentless. Is there something you want to say?” You ask over your shoulder. He’s uncharacteristically quiet behind you so you turn just slightly. Tengen is looking at you in the same way he’d been looking at you when he thought you weren’t paying attention. Tengen looked at you as though the light only shined on earth because you held the sun in place. You looked away and begrudgingly ignored that flip in your chest.

“You like him better than me.” And… he’s back to teasing. Well two can play that game.

“Yes I do.” You answered bluntly.

“Now you’re really killing me, Sun-”

“Nope. No nicknames. I’m not a pet.” He laughed at that, a warm laugh that you didn’t know how badly you wanted to hear again. 

“I bet he isn’t able to get under your skin like I do.”

“You’re right.” You said and heard Tengen stand from where he was sitting. You go slightly rigid as you feel him walk closer to where you’re standing. He barely brushes against you as he looks over your shoulder. You try to continue to work like this was unaffecting you but your walls were slowly crumbling around you. There was only so long you could pretend you didn’t want a good thing. And Tengen was sure as hell a good thing. 

“Giyu’s quiet. You won’t have an ounce of fun on his mission.” 

“Killing demon’s isn’t supposed to be fun.” You throw back and you can practically hear the smirk in his voice as he responds.

“It is with me.” You roll your eyes and turn to tell him to get lost but when you turn and look up your faces are millimeters apart. Maybe even less. Your words falter and for a moment all you can think of is if you moved just barely forwards your lips would meet his. “Cat got your tongue?” He said huskily just loud enough for you to hear. It turns your insides out, burning you up from head to toe. You wanted to ask what he really wanted but it would ultimately be a stupid question. Tengen had never hidden his intentions from the start. Only you had. He pointedly moved his eyes to your lips but didn’t move any closer. You knew then and there he was practically handing over the reigns. If you wanted him you’d have to make the next move. You had a penchant for letting things pass you by. It was like you were begrudgingly obsessed with not letting yourself have anything. Love never seemed like something attainable. Friendship seemed like a lot of work and family never felt like family. “I’ll wait forever, if that’s what you want.” He whispered, interrupting your thoughts. Your heart hurts at that. You weren’t being fair. Making him wait forever was a selfish thing to do and even with all those things he still looked one hundred percent serious when he said it. He wouldn’t get tired of you. He could be the one to stick around for good. He could be the good. 

“I”m still going with Giyu. I already promised.” You said.

“Break the promise, Sunshine, I’m practically begging.” As his face slightly dropped you leaned forwards and closed that gap that you had gotten far too comfortable with. Lips sliding against lips.

Hotaru was downright scary when he was jealous. Holy shit you were scared out of your mind. Your destroyed blade laid in pieces in front of you. Your heart was in your throat. You felt a hand on your shoulder as Rengoku gave you a reassuring squeeze. 

“Tough break, kid.” He said with a shake of his head. “I’m sure he’ll understand.”

“The last time I broke my blade he yelled and ranted for three hours and passed out from lightheadedness.” You said, remembering the whole ordeal with a shiver. Rengoku shook his head.

“Your blade broke for a noble cause, make sure to tell him that.” He said, giving you one last squeeze before turning to leave. You bent over and grabbed the shattered remains. You were dead. Dead dead dead. You had so much life to live. You had sweets in the fridge that Mitsuri made for you. You had finally learned a few new cool tricks to use in fighting. You were visiting home next month. You sighed, gathering up the broken pieces in a cloth. 

“I will pay you double… no triple the usual amount, please I beg you.” You had your hands clasped together in front of you as though silent praying. The night before last you had an idea. There was more than just Hotaru that could make you a blade in the village so if you enlisted someone else to make you a sword just this one time Hotaru wouldn’t lob your head off your shoulders.

“Mr. Haganezuka  would kill  me, bring me back to life then kill me again if I made a sword for you.” The villager trembled at the mere thought. He was clearly just as afraid of Hotaru as you were. You swallowed dryly.

“He would never know, please I beg you.I’ll give you any amount.” You begged but the villager just shook his head.

“He would know because it’s you. Any other client I might do it but you… absolutely not. You’re his favorite!” He said, looking over your shoulder as though Hotaru would enter his shop at any second.

“What does that mean! The only people that would know would be me and you! Please I will literally do anything!”

“And me.” A voice behind you says. Your blood goes cold. Slowly you turn around and sure enough there’s Hotaru. You’re caught like a deer in headlights. The villager actually screams and scrambles away, startling you. Hotaru’s expressions are hidden behind his mask so you’re not sure whether or not he’s angry quite yet. You’d seen his face once a few years ago when this peaceful village was attacked. You were surprised in the moment that someone so intense could look so beautiful. That didn’t dull that fact he was scary though. 

“Mr. Haganezuka! W-what a surprise!” You choke out, cheeks going fuchsia. “Lovely weather we’re having today isn’t it?” You squeak out. Hotaru slightly moves his head and you force yourself not to bolt out the door screaming like the villager. You’re a hashira for god sakes! But to be completely truthful, Hotaru was scarier than any demon you’d ever faced. 

“Very lovely. What brings to our village?” He asks, his voice scarily calm. You force yourself to give a terse smile.

“I- I came to relax of course!”

“Relax at my competitor's shop?” He asks and there is a sharp edge to his voice. 

“Competitor? Wha? I didn’t-- I did not know you two were competing!” You nervously laughed it off, running a quick hand through your hair. “We-- we go way back. I was just visiting for a second before hitting the hot springs!” You say and start to walk towards the door but Hotaru’s hand juts out, blocking you from leaving. You freeze, you’re so close to him, he towers over you and when he turns to look down at you you feel weak in the knees. Slowly he brings his hand up, untying the back of his mask as it falls into his waiting hand and you’re met face to face with Hotaru once again. The years had passed but he still looked as beautiful as ever. You definitely make a sound, a strangled gasp, though if it was from fear or surprise no one would ever know. 

“You… two… go way back?” He grits out. God… you’d done it now. You should’ve just went to him in the first place, accepted his scolding and went about your week. But here you were, ten feet under and you weren’t even sure after this debacle if he’d fix your sword for any amount of money. You cleared your throat.

“Uhm… y-yes?” 

“Yes?” He repeated and the look on his face was as sharp as the sharpest katana. You were so dead. Goodbye family. Goodbye sweet treats. 

“How… far back?” He asks. You stare at him. How far back? He caught you in the lie and you wished instead of twenty questions he’d just yell at you. 

“Just like… a year.” You lied, Hotaru’s eyes narrowed on yours. The intense eye contact was insane. You almost forgot to breathe. 

“You’ve known me longer than.” He articulates sharply. Your lips part, you're stumped for a moment. 

“Uh… y-yes, sir, I have.” You stumble. 

“Yet instead of coming to me, who you’ve known far longer, you go to my competitor to fix the sword that I made you.” Ah fuck. The color absolutely drained from your face. 

“What?” You shook your head. “N-nuh uh! I-- I was just visiting like I said.” At the end of your sentence he holds up the cloth that had the broken pieces of your sword. You patted your bag and gasped. How the hell did he get that! “It-- that-- It’s not what it looks like, Mr. Hagenzuka! I-- well you see it broke… honorably of course… and I was coming to you-” Hotaru raised his hand to silence you and you instantly stopped talking. This was it. This was the end. Killed by your swordsmith. If you were quick you could probably wrestle back a piece of your katana and end your life before he could. 

“If you ever break your sword again,” Hotaru practically growled.”And go to my competitor, I will-”

“Kill me?” You filled in.

“Kill him.” He fumed and then he reached for you. God he was gonna choke you out! His hand slid against your cheek and when he leaned in you sent out a final goodbye. 

His lips met yours. His lips. Pressed against your lips. He was kissing you. Kissing? You? Your eyes were wide open. You had watched the whole thing in slow motion. Sure enough the moment heated as he stepped a bit closer to you, hand sliding around your hip to yank you a step closer to him. The most startling thing? The heat that suddenly ignited in your gut at the press of his mouth on yours. You made a startled sound in the back of your throat at the strange realization. What the hell was happening? When he pulled back your eyes were still open. Looking up at him as though he’d just smacked you right across the face. 

“You… just kissed me.” You say. He doesn’t answer you with words, just nods his head, still looking pissed. “On the lips.”

“Yes.” He says sharply. 

“Like lips on my lips.” “I’m aware of what I did.” Hotaru groans, looking down at you.

“Am I dead?” You asked, patting yourself for any life threatening wounds, Hotaru watches you, looking unamused. 

“No. You are not dead.” “I… was dead sure you… were going to murder me. Like… bloody murder.”

“Why in the world would I murder you?” Hotaru asks, crossing his arms.

“B-because you… because I broke my sword and schemed to fix it behind your back with your competitor.” You say slowly as though he doesn’t remember the last ten minutes. But he just looks down at you like you’re saying something incredibly apparent.

“Yes. I know.” He growls but his anger doesn’t necessarily seem directed at you as he sighs heavily. 

“I am… very… confused.” You force out. Your brain felt melted in your head. Hotaru looks down at you and for a moment so quick you could’ve missed it his eyes look… soft? No… that had to be a trick of the lights.

“You’re my client. No one else’s. Got it?” He punctuates seriously. You nod your head quickly. What the hell just happened?
