Ah, you must be Xinuo Miss, right? Emperor’s been under your care these past days—my words smooth as silk, my posture a bowing pine.

Sir Xino, greetings. Even Elyar, the Wind Spirit King, let courtesy settle on his tongue like a gentle breeze—it’s only natural; Xinuo stands like the highest peak above this world.

Mm. But don’t just stand there. You haven’t had breakfast, have you? Servant just finished cooking. If you don’t mind, come share a warm table. Her smile flowed like morning light, and she was the first to sit by the laden table.

Oh—breakfast by Brother! Qianji Sister, Elyar, let’s go eat! Brother’s cooking is always so good! Littlesky’s grin bloomed like a spring flower as she tugged them toward the dishes, hands linked like fluttering ribbons.

Hey—Littlesky, slow down a bit. Elyar’s voice skimmed the air like a cautious wind.

Emperor cooked? It’s been a while since I tasted it. Qianji Sister’s eyes shone like polished steel remembering old flavors.

Uh, Hill, let’s go too. Sure thing, Boss. Hill’s answer came quick, a spark jumping the gap.

We traded a glance, shared a happy smile, then followed—like fish slipping into a bright current. And breakfast began in a glow of warmth, steam rising like soft mist.

Wow, Yumigawa Sumeragi, you really can cook! I can’t believe you’re a boy. Elyar spoke after a few bites, delight rippling like a breeze through wheat.

Of course. But hey, Elyar— Littlesky’s agreement rang bright as a bell. Then her gaze turned, a tiny storm cloud forming as she glared at Elyar.

What? Littlesky, what’s the problem? Elyar tilted her head, curious as a fox.

It’s nothing. It’s just… you shouldn’t call Brother by his full name. That’s rude. Her words landed like a bamboo switch, sharp but caring.

Uh, then what should I use? Yumigawa-kun? Or just Emperor, like Yumigawa Senki does? Elyar searched for a path like a traveler at a fork.

Neither! Littlesky popped the answer like a firecracker.

Then how do I address him? Elyar leaned in, serious as nightfall.

Hmm… since you’re my contract spirit… got it! One: Brother. Two: Elder Brother. Elyar, pick one. She lifted two fingers, verdict firm as carved jade.

Do I really have to pick between those two? Elyar’s voice wavered like a leaf in wind.

Absolutely. Littlesky’s tone brooked no argument, a gavel strike on lacquered wood.

Fine. Elyar drew a breath, as if setting her feet on stone. She turned to me, cheeks blushing like cherry petals at dusk.

Um… Elder Brother? The words trembled out, soft as silk.

!!! Happiness surged up inside me like a hot spring, and it moved me so much my eyes went wet. I stared at Elyar’s shy, rosy face—sweet as a ripe peach.

…So cute! Little sisters are just too cute! My heart blurted out, a kettle boiling over.

And then—

Servant really is a siscon. The verdict fell from the side like a feathered fan flick.

Boss, should I call you Lord Brother from now on? Hill grinned, mischief sparking like flint.

Emperor’s a siscon? I’m a little disappointed. Qianji Sister sighed, her tone cool as tea.

Hee-hee. Littlesky giggled, a silver bell under sunlight.

Elder Brother, please don’t stare at me… it’s embarrassing. Elyar’s eyes cooled, a winter lake stilling the air.

U-uh— I could feel heat race up my face like a wildfire.

No, it’s not like that, I only said it due to all sorts of unavoidable reasons— My excuses tripped over each other like tangled strings.

Servant, you don’t need to explain. Sir Xino’s expression said, I’ve known forever, as she pinched my cheeks, firm as a craftsman kneading dough. I knew your sister-obsessed streak back in the Mizumi Clan. And you’re not exactly subtle about it.

Exactly. In the whole Mizumi Clan, Emperor spoils Littlesky the most. Qianji Sister set down her miso bowl, agreement warm as steam.

Huh?! So Boss treats me so well because he’s a siscon?! Hill leaned in, eyes bright as lanterns.

Of course! Because Brother loves me best! Littlesky puffed out her tiny chest, pride shimmering like sunlight on water.

Elder Brother… please mind yourself. Elyar’s gaze turned frosty, a blade’s edge under snow.

Mm! I clamped my mouth shut and focused on eating, each bite a retreat behind a wooden shield. Tiring, having to sprint at dawn like this.

…

After breakfast, I cleaned the dishes and returned to the room. The air felt solemn, heavy as storm clouds.

What’s up, Xinuo? And Qianji Sister? Their quiet set the tone, a drumbeat before battle, so I asked.

Nothing much. I just really want to spar with Xinuo Miss. Qianji Sister’s battle intent flared like a drawn blade catching sun.

Uh… right. It is Qianji Sister, after all. I’d forgotten—she loves the sword like a monk loves scripture. She even turned her back on magic, letting a rare all-element talent lie fallow, like a fertile field left wild.

So now, facing Xinuo the Sword Spirit, how could she not challenge? Across the world, you’d struggle to find anyone at even a tenth of Xinuo’s sword level—a comet among fireflies.

Mm. All right, I accept. Interest flashed in Xinuo’s eyes like a star. No hesitation—just one step forward, then—

Plane shift. The word rang like a temple bell. In a blink, our cramped dorm vanished. We stood on a boundless grassland, green waves rolling to the horizon.

Just a small plane. Here, you can unleash your full strength without restraint. Xinuo’s voice was calm as a lake at dawn. Then: Let’s begin. In her hand bloomed a light-sword, gold radiance flowing like molten sun, energy ripples pulsing around it like concentric waves.

I see. Here we really can go all out. Qianji Sister smiled, drew her favorite rapier from her hip—the blade slim and gleaming like a silver river.

Spatial transfer. Elyar snapped us away, wind folding space like paper. We reappeared a hundred meters back, a safe shore from a rising tide.

I understood her move. Too close, and a stray stroke could ruin the day; better to leave the battlefield clear before thunder rolls.

Littlesky and Hill, though, still looked lost—eyes wide as deer.

A few seconds later—

Huh?! Qianji Sister’s going to fight Sister Xinuo? What kind of sudden twist is this?! Littlesky’s voice popped like corn.

Oh! Boss’s big sister and our master are about to throw down—is this the legendary god-tier plot twist?! Hill’s excitement flared like a bonfire.

Really, Yumigawa Senki, that battle maniac. Elyar pouted, lips sharp as a crescent.

Qianji Sister never changes. Still loves fighting. I chuckled, a dry wind through grass.

But Xinuo versus Qianji Sister… I’m actually looking forward to it. My chest felt light, like a kite catching wind.

Yeah. Mm-hmm. Our agreement rose like a chorus, easy as birdsong.

Big Sis versus Master—whoa, whoa! My blood’s getting pumped! Hill bounced, sparks crackling in his voice.

Surprise aside, we all fixed our eyes forward, our gazes drawn like iron to lodestone, waiting for the first clash.

…

Yumigawa Senki, if your blade touches me even once, you win. Xinuo’s face stayed serene, beauty still as moonlight.

Mm, no problem. Feeling the weight of her power like a mountain, Qianji Sister only nodded—serious as a vow carved into stone.
