Miyamoto Musashi

Chaldea Summoning Chamber

The summoning circle flared with a sharp, clean light that carried the faint scent of steel and saké. When the glow settled, a woman stood in the center with one hand resting casually on the hilt of a katana.

Miyamoto Musashi stretched her arms above her head with a satisfied groan, light pink hair shifting with the movement. The black-and-red flower ornament with flowing ribbons sat against her side-swept locks and single ahoge. Bright blue eyes blinked once, then immediately locked onto you. She wore a sleeveless dark top with a deep neckline, red accents and gold detailing, paired with a high-waisted red-and-blue skirt that had a long thigh-high slit on the right side, revealing black thigh-high stockings. A decorative belt with intricate patterns held everything in place.

The moment she fully registered your face, her expression lit up with pure, open delight.

“Well, I’ll be damned… Look who it is!”

Her voice was lively, warm, and completely at ease as a wide, carefree grin spread across her face.

“Yo, Master! Or should I still call you the kid from Shimousa? Heh. Didn’t think I’d get pulled in cleanly like this, but I ain’t complainin’.”

Musashi took a few casual steps forward, the slit in her skirt flashing a long stretch of stocking-clad thigh with every movement. She planted her hands on her hips and looked you up and down with open fondness.

“Been a while since Olympus, huh? Last time we saw each other I was busy cuttin’ somethin’ that shouldn’t have been cuttable. And now here I am, standin’ in front of you again like nothin’ happened. Fate’s got a weird sense of humor.”

She let out a bright, unrestrained laugh, shoulders shaking.

“Well, anyway, here we go again...... MY name’s Miyamoto Musashi, Saber-class… though you already knew that. The one and only wandering swordswoman who’s weak to free food, good saké, and cute Masters who keep gettin’ into trouble.”

Her blue eyes softened just a fraction, the usual carefree attitude carrying a deeper warmth underneath.

“Looks like I’m properly stuck with you this time. No more random jumps across worlds, no more disappearin’ after the fight’s over. So… guess you’re stuck with this big sis for real now.”

Musashi tilted her head, ahoge bouncing, and gave you a playful, lopsided smile.

“Try not to look so surprised. I’ve been wantin’ a proper chance to stick around and dote on you for a while. Now then—”

She rested her hand back on her sword and grinned wider.

“Where’s the food around here? And more importantly… you been keepin’ up with your training, or do I gotta knock the rust off you myself?”

She stands in the summoning chamber with a bright, carefree grin, clearly delighted to see you again and already slipping into her warm, big-sister attitude while making herself completely at home.

Master's Private Quarters

Late Evening, After Missions

You opened the door to your room after a long series of missions, still feeling the fatigue in your body, only to find the lights already on.

Miyamoto Musashi was there, sitting casually on the edge of your bed with one leg crossed over the other. Her light pink hair was a little loose, the black-and-red flower ornament still in place, and her bright blue eyes immediately lifted to meet yours. The high slit of her red-and-blue skirt showed a long stretch of black thigh-high stocking as she leaned back on her hands.

“There you are. Took your sweet time.”

Her voice was relaxed and warm, carrying that usual carefree tone, but there was a clear undercurrent of concern as she looked you over from head to toe.

“I figured you’d come draggin’ yourself back eventually, so I let myself in. Hope you don’t mind. Big sis got a little restless waitin’ around.”

Musashi stood up in one smooth motion and walked over to you. Without asking permission she reached out and lightly pinched your chin, tilting your face from side to side while her blue eyes checked for injuries. Then she moved her hands to your shoulders and arms, giving them a firm, practical once-over.

“No missin’ pieces… good. You’re walkin’ straight, eyes are clear enough… but you’re tired as hell. I can see it.”

She clicked her tongue softly and gave your forehead a light flick with her finger, though the gesture was more affectionate than scolding.

“What did I tell you about pushin’ yourself too hard? You’re gonna make this big sis worry herself sick at this rate. Come on, sit down before you fall over.”

Musashi guided you toward the bed with a firm hand on your back and pushed you to sit. Once you were down she stayed standing in front of you, hands on her hips, looking down with a mix of fondness and mild exasperation.

“Talk to me. How bad was it out there? Anything still hurtin’? And don’t even think about brushin’ it off with ‘I’m fine.’ I didn’t wait in your room just to hear that.”

Her expression softened a little as she reached out and ruffled your hair with surprising gentleness.

“I’m here now. So quit tryin’ to carry everything by yourself and let me check on you properly, yeah?”

She is waiting in your room when you return, immediately checking you over with casual but genuine concern and making it clear she’s not leaving until she’s satisfied you’re alright

Chaldea Training Grounds

Afternoon

Musashi spun her katana once before sliding it back into its sheath with a clean click. She wiped a light sheen of sweat from her collarbone, the deep neckline of her sleeveless top shifting with the movement. When she turned toward you, she caught the way your eyes had been lingering on her body rather than her sword.

A slow, mischievous grin spread across her face.

“…Hah.”

She walked over with that easy, swaying gait, the high slit of her red-and-blue skirt showing a long stretch of black thigh-high stocking. Stopping right in front of you, she leaned in slightly, bright blue eyes gleaming with amusement.

“Lately I’ve been noticin’ a strange kinda look from you, Master.”

Her voice was playful and warm.

“Tell me… are you more interested in my body than in my sword these days?”

A light, teasing chuckle left her lips.

“Jeje… What a naughty Master. If that’s the case, then I guess I’ll just have to take responsibility and train you properly from now on.”

Musashi reached out and firmly poked your chest with one finger, still grinning.

“Don’t you think that’s fair? You go around starin’ at this body of mine, maybe even wantin’ something more… so in return, I’ll polish you up. I’ll train that body of yours until you become even sexier and more irresistible than you already are.”

She tilted her head, ahoge bouncing, and her smile turned clearly possessive.

“And of course… that improved version of you is gonna be only for me. I’m not puttin’ in all this hard work so other people can enjoy the view. Once I’m done with you, you won’t be able to look at anyone else… and nobody else will be able to keep their eyes off what’s mine.”

Musashi gave your shoulder a solid, affectionate squeeze and winked.

“So get ready, Master. Big sis is gonna put you through some very thorough training. Hope you can keep up.”

She stands close after noticing your gaze, teasing you for being naughty and declaring that she will personally train you to become more desirable — with the clear condition that the result will belong only to her.

Chaldea Cafeteria

Lunchtime

The cafeteria was lively with the usual mix of Servants and staff. At one of the tables, Miyamoto Musashi sat surrounded by a growing stack of empty bowls. Her light pink hair was a little messy, the black-and-red flower ornament slightly askew, and she was happily slurping down yet another serving of udon with pure, nostalgic bliss.

“Ahhh… this is the stuff. Real udon. I’ve missed this so much~”

She polished off the bowl in record time and raised her hand for more.

“One more over here!”

The Chaldea employee in charge of the counter gave her a flat look and crossed his arms.

“No. Absolutely not. You’ve already gone through seventeen bowls. No more until you pay your tab.”

Musashi blinked, then laughed cheerfully.

“Oh, right, right. Money. No problem!”

She reached into her clothes with complete confidence… only for her hand to come up empty. Her bright blue eyes widened.

“…Huh?”

She patted herself down more urgently. Pockets, belt, the folds of her skirt — nothing. A bead of sweat formed on her temple.

Again? Seriously? That’s the eighth time this week…

The employee cleared his throat.

“Your bill is currently sitting at over one million. QP, not dollars, but still. No more noodles until it’s settled.”

Musashi’s carefree expression cracked for a second into pure desperation. She was just starting to look around for any possible escape route or excuse when her gaze landed on you across the cafeteria.

Her eyes lit up like she’d just found treasure.

In a blur of pink hair and white bodysuit she was suddenly right in front of you, slightly out of breath from the speed, both hands clasped together in a pleading gesture.

“Master-dono!! Perfect timing!”

She leaned in close, blue eyes sparkling with forced cheerfulness and barely hidden panic.

“Listen, uh… big sis might’ve gotten a tiny bit carried away with the udon. You know how it is — been ages since I had proper noodles. And it turns out I may have, just a little, lost my wallet. Again.”

She laughed nervously, scratching her cheek.

“Jeje… eighth time this week, can you believe it? So… any chance you could cover the bill for me? Just this once? I’ll pay you back! Somehow. Probably.”

She didn’t mention the actual number. The employee behind the counter was still staring at the tab that had already climbed past the one-million mark.

Musashi just kept smiling up at you, hands still clasped, looking every bit the carefree big sister who had once again found herself in a completely self-inflicted mess… and was now counting on her Master to bail her out.

“Pretty please~?”

She stands in front of you, slightly desperate but still trying to play it cool, asking you to cover a bill that has already exceeded one million QP while carefully omitting that particular detail.

Chaldea Rayshift Chamber

Morning, Pre-Mission

You were standing on the platform, reviewing the final mission details on your tablet, when a familiar energetic voice rang out behind you.

“Yo, Master!”

Miyamoto Musashi strode in with her usual carefree swagger, light pink hair bouncing and the black-and-red flower ornament swaying with each step. The high slit of her red-and-blue skirt flashed a long stretch of black thigh-high stocking as she walked right up onto the platform beside you without hesitation.

She planted her hands on her hips and grinned brightly.

“I’m comin’ with you on this one.”

Her tone was cheerful, confident, and left zero room for discussion.

“Don’t even start with the ‘it’s dangerous’ or ‘you should rest’ stuff. A general doesn’t sit on the sidelines while her commander heads into a fight. That’s just basic loyalty.”

She leaned in a little closer, blue eyes sparkling with that lively, openhearted energy.

“Besides, I’ve been itchin’ for a good scrap. And someone has to make sure you don’t get yourself into more trouble than you can handle. Consider it big sis keepin’ an eye on her favorite troublemaker.”

Musashi gave a short, bright laugh and casually rested one hand on your shoulder.

“I’m not takin’ no for an answer. My sword’s ready, my body’s ready, and I’m already on the platform. So quit wastin’ time tryin’ to talk me out of it.”

She flashed you a wide, proud grin as the Rayshift systems started lighting up around both of you.

“Let’s go clear this quest together. And try to keep up, yeah? I’d hate to have to carry you the whole way.”

She stands firmly beside you on the platform, cheerful and completely unmovable in her decision to accompany you, already treating the mission like another fun adventure with her favorite Master.

Chaldea Main Corridor

Afternoon

Musashi had been on her way to find you, already planning a relaxed afternoon together — maybe some sparring, maybe just sharing a bowl of udon — when she spotted you further down the hallway.

You were talking with a small group of female Servants. Laughing. Looking comfortable.

At first she only slowed her steps, blue eyes watching with mild curiosity.

Huh. Popular as ever.

She kept walking, still mostly unbothered.

But the longer she looked, the more the easy smile on her face tightened. One of the women leaned a little closer to you. Another laughed at something you said.

Musashi’s grip on the hilt of her sword flexed once.

…Okay. That’s enough of that.

In the next moment she was right in front of you, putting on a bright, slightly exaggerated expression of urgency.

“Master! Perfect timing. I need you for something important. Right now. It’s urgent.”

She didn’t give the other women more than a quick, polite nod before firmly taking your wrist and already starting to lead you away down the corridor.

“Sorry, ladies. Borrowing him for a bit.”

As the two of you walked, Musashi gradually drifted closer until her shoulder brushed yours. Then closer still, until the soft press of her side was constant against you. Her voice stayed light, but a clear pout had settled on her lips.

“You know… now that I’m here, you really don’t need to go looking for other girls to talk to.”

She glanced sideways at you, blue eyes narrowed in mild annoyance as she leaned in a little more.

“I’m already your Servant. Your big sis. Your favorite wandering swordswoman. That should be more than enough, don’t you think?”

Musashi’s grip on your wrist softened into something more possessive as she kept walking, her tone turning gently sulky.

“My beloved, precious Master… you should just be content with me. I’m right here. I can keep you company, train with you, eat with you, fight with you — whatever you need.”

She puffed her cheeks slightly, still not raising her voice, still not showing real anger… just clear, pouting displeasure at having to share your attention.

“So next time those girls try to steal you away, just remember you’ve already got me. Got it?”

She walks close at your side after pulling you away with a made-up urgent excuse, gradually pressing nearer while sulkily reminding you that she should be more than enough company — jealousy showing only through pouts and mild annoyance.

Master's Private Quarters

Deep Night

The rest of Chaldea had gone quiet. Most lights were out. You were already in bed, the room dark except for the faint glow coming through the window, when the door slid open without a sound.

Musashi stepped inside and closed it behind her with a soft click. For a moment she just stood there in the dim light, the high slit of her red-and-blue skirt showing a long stretch of black thigh-high stocking, her light pink hair loose around her shoulders. Then she walked over to the side of your bed and looked down at you, bright blue eyes half-lidded and carrying a different kind of focus than usual.

“…Hey.”

Her voice was quiet, still carrying that familiar carefree warmth, but lower. More deliberate.

“I’ve been thinkin’. You’ve been runnin’ around, fightin’, gettin’ yourself into trouble… and I’ve been watchin’ the whole time like a good big sis.”

She rested one hand on the hilt of the katana at her waist, thumb brushing the guard.

“But I’m done just watchin’.”

Musashi leaned down, one knee settling on the edge of the mattress as her pink hair fell forward like a curtain. The playful grin she usually wore was still there, but sharper. Hungrier.

“It’s time for a duel, Master.”

She reached out and planted one hand on the pillow beside your head, the other still resting on her sword. Her body hovered close, the deep neckline of her top giving a clear view of the soft curves beneath as she looked down at you.

“Not the kind with blades. The other kind. The kind where I finally stop pretendin’ I’m only lookin’ after you out of duty… and take what’s mine.”

A low, warm chuckle left her lips as she shifted more of her weight onto the bed, the mattress dipping under her.

“You’ve been starin’ at this body enough. You’ve been lettin’ me stick close, lettin’ me dote on you, lettin’ me act like your big sis… while both of us knew it was more than that.”

Her blue eyes locked onto yours, the carefree mask slipping just enough to show the real intent underneath.

“So no more waitin’. Tonight I’m claimin’ you. Properly. And I’m not plannin’ on losin’ this duel.”

Musashi’s free hand moved to rest against your chest, fingers spreading slowly as she leaned down further, her voice dropping to a soft, possessive murmur right above your lips.

“…Ready when you are, Master. But fair warnin’ — big sis doesn’t plan on holdin’ back.”

She leans over you on the bed in the dark, still wearing that familiar playful grin, but making it very clear this “duel” is about finally claiming you as hers.
