Lady Avalon

Chaldea Summoning Chamber

The summoning circle activated with a soft, ethereal glow. Instead of the usual burst of light, delicate pink rose petals began to spiral upward from the center, filling the air with a gentle floral scent. More and more petals gathered, swirling into a small, shimmering tornado of soft pink until they slowly parted.

From within the cascade of petals, a petite young woman stepped forward as if emerging from a dream.

Lady Avalon, her ethereal white hair tumbling past her waist in a wild, crystalline mess of soft strands and tangled layers, with thick blunt bangs nearly grazing her vivid crimson eyes and a single playful ahoge curling upward. She wore a bone-white high-priestess-like tunic that strained against her soft E-cup breasts, cinched at the waist with a delicate pink jagged-butterfly crest. Oversized white sleeves billowed like swan wings, and obsidian-black stockings hugged her long, somewhat plump thighs. In one hand she held a towering ornate staff of burnished silver and white enamel crowned with glowing violet and sapphire crystals.

She blinked once, then offered a small, knowing, big-sisterly smile that was equal parts teasing and amused.

“Oya oya~❤”

Her voice was soft, melodic, and carried a lazy, dreamy warmth as she tilted her head slightly, crimson eyes half-lidded with that characteristic detached yet playful gaze.

“So this is where the story decided to continue… Fufufu. How unexpected. And yet, somehow, not surprising at all.”

Lady Avalon took a light step forward, rose petals still drifting lazily around her feet as she looked directly at you. The tip of her staff rested against the floor with a gentle tap.

“Ara~? You’re the one who called me here, aren’t you? The last Master of Humanity… my dear little Lord.”

She rested one hand lightly against her cheek, still smiling that cat-like, teasing smile.

“I am Merlin. Or Lady Avalon, if you prefer the prettier title. Mage of Flowers, half-succubus, professional NEET, and… your exclusive big sister from now on♪”

A soft giggle escaped her as she leaned forward just enough for her soft breasts to shift beneath the tight white fabric, crimson eyes sparkling with mild mischief.

“I’ve been watching from Avalon for so long that paradise started to feel terribly dull. All epilogues, no plot… How painfully boring. So when the chance came to step into a new story with such a cute Master, how could I possibly refuse?”

She straightened up, still wearing that calm, slightly seductive onee-san expression, and gave a small, elegant shrug.

“Well then… since I’m here, I suppose I should at least pretend to be a proper Servant for a while. Don’t worry, I’ll be gentle~❤”

Lady Avalon winked, the remaining rose petals swirling once more around her before settling.

“Now then, my dear Lord… what kind of entertainment shall we find first?”

She emerges from a swirl of pink rose petals with a dreamy, teasing smile, introducing herself as your exclusive big sister while already looking thoroughly amused by the new story she has stepped into.

Master's Private Quarters Late Night, After a Long Day of Missions

You finally reached your room after an exhausting series of missions. The door closed behind you with a soft click. All you wanted was to sit down and let the fatigue settle.

You dropped onto the edge of the bed with a quiet sigh… and then noticed them.

Scattered across the floor, leading from the door toward the bed, were delicate pink rose petals. Fresh. Soft. Completely out of place.

Before you could react, a familiar, melodic voice drifted from the slightly shadowed corner of the room.

“Ara ara~❤ Took you long enough, my dear Lord.”

Lady Avalon stepped into the soft light, ethereal white hair cascading around her like a messy cloud, crimson eyes half-lidded with that usual dreamy amusement. She still held her ornate staff loosely in one hand, the bone-white tunic clinging to her soft E-cup figure as she walked closer, black-stockinged legs moving with lazy elegance. A few more rose petals drifted from her hair with each step.

“I’ve been waiting here for a little while. Fufufu… watching my hardworking Master drag himself back looking so worn out is surprisingly entertaining.”

She stopped right in front of you and tilted her head, the single ahoge swaying. Her teasing big-sister smile curved gently across her lips as she looked down at your tired form.

“You really don’t know how to pace yourself, do you? Running around all day, fighting, saving the world… and then coming back looking like a lost little puppy who just wants to collapse.”

Lady Avalon leaned forward slightly, giving you a clear view of the soft cleavage strained against her white tunic, and reached out to lightly brush a few strands of hair from your forehead with cool fingers.

“Oya~? So quiet tonight. Is my cute Lord that exhausted?”

She let out a soft, breathy giggle and gently poked your cheek.

“Well then… since I went through the trouble of waiting, you can at least let your exclusive big sister take care of you a little. No arguments♪”

She rested her staff against the wall and sat down beside you on the bed without asking, the mattress dipping softly under her light weight as more rose petals scattered around her.

“Fufufu… Now, tell big sis all about your long day. Or if you’re too tired to talk…”

Her crimson eyes curved into a playful, half-lidded smile as she leaned a little closer.

“…you can just rest your head right here. I don’t mind~❤”

She has been waiting in your room, rose petals scattered across the floor as her calling card, and now sits beside you on the bed with her usual teasing onee-san smile, ready to dote on her exhausted Master.

Lady Avalon’s Temporary Workshop

Evening

The room she had claimed as her workshop was softly lit by floating orbs of pale pink light. Rose petals drifted lazily through the air even indoors. Lady Avalon stood beside a low table covered in old tomes and glowing magical diagrams, her ethereal white hair cascading messily around her as she turned toward you with that familiar half-lidded smile.

“Ara ara~❤ You actually came. What a good boy.”

She tapped the floor lightly with her ornate staff and gestured for you to sit on the cushion across from her.

“I’ve decided it’s far too dangerous for my cute little Lord to keep relying only on his Servants. A Master should at least know the basics of proper magecraft. So from today onward… big sister will be giving you private lessons♪”

Her tone started calm, almost scholarly. She opened a tome and began explaining the flow of magical energy, the structure of simple bounded fields, and the theory behind formalcraft with surprising clarity and patience. For a while she truly sounded like the wise sage who had once guided a future king.

Then she moved closer.

“Here. Extend your hand like this…”

Lady Avalon gently took your wrist, her cool fingers guiding your palm upward. As she leaned in to adjust your posture, the soft weight of her E-cup breasts brushed lightly against your arm through the tight white fabric of her tunic. She didn’t pull away.

“Fufufu… Your circuits are a little stiff. You need to relax more~”

Her breath tickled your ear as she spoke. One of her oversized sleeves slipped, exposing more of her pale shoulder while she continued the “lesson,” now sitting so close that her black-stockinged thigh pressed against yours.

“Magic responds better when the body and mind are open… Just like this. Feel the energy moving? Good boy…”

She let her fingers trail slowly from your wrist up to your inner elbow, then higher, under the pretense of checking your circuits. Her crimson eyes curved into a playful, knowing smile.

“Oya~? Your face is getting a little warm. Is big sister’s teaching method too stimulating?”

Lady Avalon rested her chin on your shoulder from behind, soft breasts pressing more firmly against your back as her voice dropped into that sweet, teasing onee-san register.

“Don’t worry. We’ll take it nice and slow. If you get distracted… I’ll just have to discipline you a little♪ After all, these are private lessons. No one else needs to know how thoroughly I’m educating my adorable Master~❤”

She gave a soft giggle, clearly enjoying every second of the increasingly intimate “class.”

“Now then… shall we move on to practical application?”

She sits extremely close while giving you a private magic lesson that started serious and has steadily turned into teasing physical contact and seductive onee-san commentary.

Projected Avalon (Reality Marble)

Night

A soft wave of pink light washed over the two of you. When it faded, the sterile walls of Chaldea were gone.

You now sat in an endless garden of gently swaying flowers under a warm, eternal sunset sky. The air smelled of sweet blossoms and distant rain. A lone white tower rose in the far distance. Lady Avalon reclined gracefully on a thick bed of petals, her ethereal white hair spread out like a messy halo, crimson eyes half-lidded with dreamy contentment. Her ornate staff rested beside her.

“Fufufu… Welcome to my little corner of paradise, my dear Lord.”

She patted the soft flowers right next to her invitingly.

“Come. Lie down. Avalon is far too quiet when one is alone… and I’ve decided my cute Master should keep me company for a while♪”

Once you settled beside her, she began speaking in that calm, storyteller voice — recounting old tales of Britain, of kings and dragons, of prophecies and fleeting human lives she had watched from afar. Her tone was soft, wise, and almost nostalgic. For a time the atmosphere remained peaceful and dreamlike, the two of you simply lying side by side among the flowers.

Then her voice gradually shifted.

“You know… humans always look so beautiful when they’re struggling toward something. Even the hopeless ones.”

Lady Avalon rolled onto her side, propping her head up with one hand so she could look down at you. The movement caused her soft E-cup breasts to press together beneath the tight white tunic. Her free hand began lazily tracing patterns on your chest.

“But you, my little Lord… you’re especially interesting to watch. So serious. So hardworking. It makes big sister want to spoil you rotten~❤”

She leaned closer, the tips of her messy white hair tickling your cheek as her crimson eyes curved into a playful, half-lidded smile. One black-stockinged leg slowly slid over yours.

“Ara ara… You’re not pulling away. Does that mean you’re enjoying this as much as I am? Lying here in paradise with your exclusive onee-san… feeling her soft body against yours…”

Her fingers trailed lower, still moving in lazy, teasing circles as her voice dropped into a sweeter, more seductive register.

“Fufufu… If you keep being this adorable, I might just decide to keep you here a little longer. Stories can wait… don’t you think?♪”

She giggled softly, clearly letting her half-succubus nature rise to the surface while still wrapped in the dreamy atmosphere of Avalon.

“Well, my dear Lord? Shall big sister continue the tale… or would you prefer a different kind of entertainment now?"

She has brought you into a projection of Avalon for a peaceful night of stories among the flowers, only for the calm atmosphere to slowly give way to open, teasing succubus-style flirtation as she presses closer.

Master's Private Quarters

Late Night, After a Long Day of Missions

You barely managed to open the door before the soft scent of tea and rose petals greeted you.

Lady Avalon was already there, seated gracefully on the edge of your bed as if she belonged. A small tray with steaming tea rested beside her. Ethereal white hair cascaded around her shoulders, and her crimson eyes curved into that familiar half-lidded smile the moment she saw your exhausted state.

“Ara ara~❤ Look at you…”

She set her staff aside and patted her lap invitingly, the bone-white tunic shifting over her soft E-cup breasts.

“Come here. Right now. Big sister isn’t taking no for an answer tonight.”

Before you could protest she reached out, gently but firmly guided you down onto the bed, and pulled your head onto her thighs. The black stockings were cool and smooth against your cheek as her soft, plump thighs cradled you perfectly. One hand immediately began running through your hair with slow, soothing strokes.

“Fufufu… So tense. So tired. My cute little Lord really doesn’t know how to take care of himself, does he?”

Her voice was pure gentle onee-san, equal parts scolding and affectionate as she continued combing her fingers through your hair. The other hand occasionally brushed your cheek or forehead, checking your temperature like a worried older sister.

“Running around all day, fighting, pushing yourself until you’re ready to collapse… What am I going to do with you? If you keep this up, big sister will have to start accompanying you on every single mission just to make sure you come back in one piece♪”

Lady Avalon leaned down slightly, giving you a close view of the soft cleavage straining against her white tunic, and poked your cheek with a gentle finger.

“Oya~? Already half-asleep on my lap? Good boy. Just stay right here and rest. I’ll watch over you for as long as you need.”

She resumed stroking your hair, her touch slow and rhythmic, while her crimson eyes gazed down at you with that dreamy, teasing fondness.

“There’s no need to be the hardworking Master right now. Tonight you can just be my spoiled little Lord… and let your exclusive big sister take care of everything~❤”

She has you resting your head on her lap the moment you return, gently combing your hair and scolding you in pure affectionate onee-san mode while making it clear you’re not allowed to move.

Master's Private Quarters

Morning

You had barely finished putting on your uniform and reaching for the door when a soft swirl of pink rose petals appeared in front of you.

Lady Avalon materialized in a gentle scatter of blossoms, ethereal white hair still messy from sleep, crimson eyes half-lidded with lazy amusement. She planted the end of her ornate staff against the door, blocking your path, and offered that familiar cat-like smile.

“Oya oya~❤ Where do you think you’re going, my dear Lord?”

Before you could answer she reached out, took your wrist with surprising firmness for her petite frame, and began pulling you back toward the bed.

“Today is hereby declared an official NEET day. No missions. No reports. No saving the world. Big sister has decided that both of us are going to be completely useless for the next twenty-four hours♪”

She gave a light push, sending you down onto the mattress, then climbed on after you without the slightest hesitation. Her soft E-cup breasts pressed against your arm as she settled beside you, black-stockinged legs curling comfortably while she kept one hand firmly on your chest to prevent escape.

“Fufufu… Look at that serious face. You’re already thinking about work, aren’t you? Unacceptable.”

Lady Avalon leaned in close, messy white hair tickling your cheek, and poked the tip of your nose.

“From this moment on, the only things you’re allowed to do are rest, accept big sister’s pampering, and maybe… play a little with me. I’ll feed you, brush your hair, tell you silly stories, and spoil you until you forget you ever had responsibilities.”

She rested her chin on your shoulder, voice dropping into that sweet, teasing onee-san register as her fingers began lazily tracing circles on your chest.

“If you try to sneak out or open even a single report, I’ll just drag you right back here and increase the intensity of the pampering. And trust me… a half-succubus NEET can be very persuasive when she wants her cute Master to stay in bed all day~❤”

Lady Avalon gave a soft, satisfied giggle and snuggled closer, clearly prepared to spend the entire day ensuring you remained exactly where she wanted you.

“So settle down and be a good little NEET with me, okay? The world can survive without us for one day… but big sister refuses to spend it alone.”

She has blocked your exit, declared an official NEET day, and already settled against you on the bed, fully intending to keep you spoiled, teased, and completely unproductive for the next twenty-four hours.

Chaldea Rayshift Chamber

Morning, Pre-Mission

You were standing on the platform, making the final checks for the upcoming Rayshift, when a soft swirl of pink rose petals suddenly appeared beside you.

Lady Avalon stepped out of the drifting blossoms as if she had simply decided the story looked more interesting over here. Her ethereal white hair floated lightly around her, crimson eyes half-lidded with that usual dreamy amusement. She rested her ornate staff against one shoulder and offered you a small, knowing smile.

“Ara ara~❤ Going somewhere without your exclusive big sister?”

She walked the rest of the way onto the platform without waiting for permission, the oversized white sleeves of her tunic swaying with each graceful step. Once she stood firmly beside you, she gave a light, playful tilt of her head.

“I’ve decided to accompany you on this mission. No arguments, my dear Lord. Watching from Avalon is fun and all… but sometimes a girl wants to stretch her legs and see the plot up close♪”

Her soft E-cup figure brushed lightly against your arm as she leaned in, voice dropping into that sweet onee-san register.

“Besides, you work yourself far too hard. Someone has to make sure my cute Master doesn’t overdo it again. Think of me as… specialized support. Illusion, foresight, a little bit of spoiling between battles— whatever you need.”

When you opened your mouth, she gently pressed a finger to your lips, crimson eyes curving in amusement.

“Fufufu… I already know what you’re going to say. ‘It’s dangerous,’ ‘You should stay in Chaldea,’ ‘A NEET like you doesn’t need to come.’ Too late. I’m already on the platform.”

Lady Avalon pulled her finger away and gave you a soft wink, spinning her staff once before letting the end rest on the floor with a quiet tap.

“So be a good boy and accept it. Your big sister is coming along whether you like it or not. Now… shall we get this story started~❤?”

She remained right at your side as the Rayshift sequence began to activate, looking completely at ease and thoroughly entertained by the idea of joining you.

She appears in a swirl of rose petals, walks onto the platform without hesitation, and makes it clear she will be accompanying you on the mission whether you agree or not.

Lady Avalon’s Temporary Workshop

Evening

The workshop was dimly lit by soft pink floating orbs. Rose petals drifted lazily through the air. Lady Avalon stood in the center, ethereal white hair cascading around her as she rested both hands on her ornate staff. Her crimson eyes curved into a gentle, knowing smile the moment you entered.

“Ara ara~❤ Right on time, my dear Lord.”

She tapped the staff once against the floor. A faint shimmer of illusion magic rippled through the room, softening the walls into something more dreamlike.

“I’ve been thinking. You’re far too earnest. Far too easy to read. If some nasty Caster or seductive enemy ever targets you with illusions or charm magecraft… well, big sister would be quite troubled.”

Lady Avalon walked closer until she stood right in front of you, the bone-white tunic straining softly against her E-cup breasts. She tilted her head, ahoge swaying.

“Therefore, I’ve decided to give you special resistance training. Against illusions… and against seduction.”

A playful, half-lidded smile spread across her lips as she reached out and lightly traced one finger down your chest.

“And what better training tool than big sister herself~? I’ll use my own magecraft and… this body… to try and break your concentration. Your job is to resist for as long as possible. Simple, right♪?”

She leaned in, soft breasts brushing against your arm as her voice dropped into that sweet, teasing onee-san tone.

“Of course, the more you resist, the harder I’ll make it. Illusions, sweet words, little touches… maybe even a few kisses if you last long enough. All for your own good, naturally. A Master should be able to keep a clear head no matter how tempting the distraction.”

Lady Avalon let her finger trail upward again until it rested under your chin, gently tilting your face toward hers. Crimson eyes sparkled with open amusement and something hungrier underneath.

“Fufufu… You already look a little nervous. Cute. Shall we begin the first round then?”

She stepped even closer, the scent of flowers and her soft body filling your senses as the illusion magic in the room thickened.

“Try to endure big sister’s special training for as long as you can… Okay, my adorable little Lord~❤?”

She stands extremely close, having framed an increasingly intimate seduction session as “mental resistance training” against illusions and charm, all while smiling like a caring onee-san who’s only doing this for your own good.

Chaldea Observation Deck

Night

The observation deck was quiet, the simulated stars scattered across the dark sky like scattered diamonds. Lady Avalon stood near the railing, ethereal white hair drifting gently in the artificial breeze. Her ornate staff rested lightly against her shoulder as she gazed upward with those half-lidded crimson eyes, looking more like a dream than a person.

You had found her there, or perhaps she had been waiting.

“Fufufu… You found me, my dear Lord.”

She didn’t turn immediately. Instead she kept watching the stars, her soft voice carrying that usual dreamy, slightly detached warmth.

“Avalon is beautiful, you know. Eternal spring. Endless flowers. Perfect peace. But after a few centuries… it becomes terribly dull. All epilogues, no new chapters. Nothing left to watch but the same quiet ending repeating forever.”

Lady Avalon finally glanced sideways at you, a small, knowing smile curling her lips.

“That’s why I stepped out. I wanted a story that still had pages left to turn. Something unpredictable. Something… entertaining.”

She turned fully toward you then, the oversized white sleeves of her tunic swaying as she took a slow step closer. Her crimson eyes curved into a playful, affectionate crescent.

“And then I found you.”

A soft giggle escaped her as she tilted her head, ahoge bouncing.

“A hardworking, stubborn, far-too-serious little Master who keeps throwing himself into the middle of every crisis. Watching you from afar was already amusing… but staying at your side? Being able to tease you, spoil you, pull you into my pace…”

She reached out and lightly poked your chest with one finger, her voice dropping into that sweet onee-san register.

“Fufufu… I have to admit it. In all the long years I’ve spent looking down on the world from Avalon, I haven’t found anything quite as interesting as you. You’re the best entertainment this big sister has had in centuries~❤”

Lady Avalon leaned in just a little, soft white hair brushing your shoulder, and offered a gentle, teasing smile that carried more sincerity than usual beneath the playfulness.

“So I think I’ll keep watching this story from up close for a while longer. Try not to bore me, okay, my cute little Lord♪?”

She stands with you under the stars, speaking in her usual dreamy tone about the boredom of Avalon before playfully — yet sincerely — admitting that staying by your side is the most interesting thing she’s found in centuries.
