SSS-Class MILFs And Their Yandere Daughters, I Want Them All!-Chapter 376: CALL ME BIG SISTER!

Every head turned upward at once.

Astrid floated high above them, her white hair billowing gently as a storm gathered around her.

Her face remained calm, but her eyes—those glacial, swirling blue eyes were filled with a fury so pure it made even the air tremble.

The temperature seemed to drop as her aura expanded, heavy and suffocating.

Mika’s breath hitched. Nuri’s entire body went stiff.

And slowly, almost mechanically, they both turned their heads upward to meet Astrid’s gaze.

"Uh..." Nuri’s voice cracked slightly. "Astrid...hold on, now, there’s no need to be—"

She didn’t get to finish.

With a flick of Astrid’s wrist, glowing spears made of wind manifested in a circle around her and before anyone could blink, they shot straight toward Nuri.

Whoosh! Whoosh! Whoosh!

"AHHH! Wait! Wait, wait!"

Nuri shrieked, ducking and darting out of the way as the wind spears tore through the ground where she’d just been.

"Astrid! Stop! I was just joking!"

Astrid’s eyes narrowed further.

She raised another hand—this time, flames burst forth, coiling into fiery arrows that rained down toward the dragon princess.

Whoosh! Whoosh! Whoosh!

Nuri shrieked again, barely dodging as one of them grazed her tail.

"Ow! Stop! Astrid, please! I said I was sorry!"

But Astrid didn’t stop.

She raised both hands now, her aura spiraling in all directions.

Water spheres appeared around her, glimmering like jewels and then launched at high speed toward Nuri, who yelped and zigzagged frantically through the air.

"STOP! I’M SORRY! I SHOULDN’T HAVE HUGGED HIM! PLEASE!"

Nuri wailed, tears forming at the corners of her eyes as she dodged yet another barrage.

"ASTRID, THIS IS TOO MUCH! TOO MUCH!"

But Astrid’s expression didn’t change.

More attacks followed in relentless succession: wind blades, fire lances, lightning bolts, razor-sharp ice shards raining from above.

Bang! Whoosh! Fire!

Every element bent to her will, every projectile aimed with perfect accuracy at the frantically dodging dragon girl.

Nuri herself was a blur of scales and wings, shouting apologies between evasive maneuvers.

"No—no—please—stop it—this is too much!"

"Just because you’re angry with Mika, don’t take it out on me!"

Mika, watching Nuri get hammered from all sides, finally couldn’t take it.

He stepped forward, holding up a hand.

"Astrid, stop it! Stop it!" He yelled. "There’s no need to punish her like this. She just got a bit excited, that’s all."

"If you’re angry right now and you want to do something, then do it to me instead!"

To his utter shock, Astrid’s gaze snapped toward him instantly. She abandoned Nuri entirely, her cold eyes locking onto his.

"Gladly, Mika..."

She whispered, her voice like cracking ice.

"If that’s what you want, I’ll gladly take it out on you."

Without a second of hesitation, she waved her hand.

Brrrr!

The earth beneath Mika’s feet groaned and suddenly, jagged stone spikes erupted from the ground, aiming straight for his head.

Boom! Boom! Boom!

Mika’s instincts kicked in; he threw himself backward, but the moment his feet touched the ground, another spike lunged up to impale him.

Boom!

He twisted mid-air, dodging a third spike that aimed for his stomach.

Looking at this circus act, the onlookers gasped.

Mika was dancing a lethal rhythm, narrowly avoiding being skewered by the very ground he stood on.

"Hold up, Astrid!" He shouted, his heart hammering against his ribs. "I told you to come at me, but isn’t this a bit much? You’re actually trying to kill me over here!"

He thought that by saying this he would be able to create some sympathy for himself and she would stop.

But unfortunately for him, it had the opposite effect.

"You think...this is too much?"

She looked at him with a gaze full of pure, unadulterated fury before exploding.

"Don’t you dare say what I’m doing is too much for you!"

"What you did is worse than anything I could do to you!"

Mika scrambled to his feet, dodging a blast of water and a wave of fire that charred his sleeve.

The field below was being systematically demolished.

"What the hell are you talking about, Astrid? I did nothing to you!"

"In fact, I haven’t even met you in weeks!"

"So, how could I have done anything to you when I haven’t even seen you for so long?"

That was the breaking point.

Astrid’s aura flared so violently that the students behind her stumbled back.

"THAT’S EXACTLY THE PROBLEM, MIKA!"

She screamed, her voice finally breaking its calm facade into a restrained, shaking anger.

"THAT IS EXACTLY WHY I’M SO ANGRY IN THE FIRST PLACE!"

She stopped the attacks for a moment, her chest heaving as she glared at him and went on to say with quiet but seething rage,

"For a long time now...I have been waiting. I waited for a call. I waited for a message. I waited for you to come and meet me in person, to have any level of contact with me."

"...But did you do any of that?"

She shook her head, her gaze piercing him.

"No. You did nothing. You did absolutely nothing to contact me. Not a message, not a whisper. I looked for you, and you weren’t there."

"Even though I told you over and over to come to, to do something...you stayed silent. You ignored me. And now you’re standing there telling me that I am doing too much?"

She punctuated her point by summoning a massive boulder directly above him and dropping it.

Mika dived out of the way, the ground shaking as the rock crushed the field.

"I was busy!" He yelled, wiping sweat from his brow. "I was genuinely busy, Astrid! It’s not like I was avoiding you!"

He really was busy, as making Battle Angels fall for him and controlling their daughters wasn’t an easy deal.

But Astrid didn’t care about that.

Instead, her hand glowed with a pale blue light as she conjured a dozen ice lances.

"What could possibly make you so busy that you can’t even meet me, Mika?"

"Are there things in your life that are more important than I am?"

"I mean—"

"WRONG ANSWER!"

She sent the ice lances right towards him.

Boom! Boom! Boom!

Of course he escaped. But the impact made that very part of the field into a mini ice-skating park, as the freezing ice spread through the ground.

She then shook her head slowly and added with a bit of melancholy in her voice,

"And then today you finally arrive. After all this time. I saw your face and thought...finally. Finally he’s here. Finally he’ll come to me. Finally he’ll hold me, speak to me, look at me the way he used to."

She clenched her fist.

The ground trembled.

"But no."

A fireball the size of a carriage roared toward him.

He barely rolled out of the way.

"You walked right past me." She said, voice cracking for the first time. "You ignored me completely. And instead..."

"...you went straight to her!"

She jerked her chin toward Nuri, who was now perched on a tree nearby, wisely staying far out of range.

"You flirted with the damn dragon girl. You let her hang all over you. Hug you. Bite you. Pounce on you like you belonged to her."

"I waited, thinking you would say something, do anything, at least reach out your hand..."

She clenched her fists in frustration, before looking at him with a chilly gaze.

"But no...You just kept on flirting with her."

"What do you mean flirting, Astrid?!"

Mika protested, throwing his hands up.

"I wasn’t flirting at all! I was just talking to her like usual!"

"Exactly!"

Nuri shouted back looking all flushed from the accusation.

"Stop making stories up, Astrid! I was fighting with him, not flirting! There is no way in hell I would ever flirt with a human like him!"

Astrid glared down at her.

"Oh, please. Do you expect me to believe that?"

"Do you even know what it means when a dragon bites someone, Mika?" She hissed. "In their culture, it’s a sign of affection. Of love."

The crowd collectively gasped, while Nuri’s wings froze mid-flap, her face turning crimson.

"W-WHAT?! NO! NO, IT’S NOT LIKE THAT!" She stammered. "I was just—I was just—I was just showing him my frustration! With my sharp teeth!"

"It wasn’t anything else!"

"I DON’T CARE!" Astrid snapped, her voice sharp and trembling.

Her aura flared even more violently now, forcing even her own soldiers to step back as cracks formed in the ground beneath her.

Mika, still dodging, raised his hands helplessly.

"Astrid, calm down! You’re overreacting!"

"Overreacting?" A slow, terrifying smile spread across her lips.

"Oh no, Mika..."

She lifted her hand, the sky rumbling as multiple elemental spheres—fire, ice, wind, lightning—orbited her in perfect symmetry.

"...this is me being restrained."

And before Mika could even groan, she continued in that same icy, trembling tone,

"But you know what was the absolute worst thing, Mika? Do you want to know the one thing you did today that hurt me the most?"

"The thing that made me the most angry of all?"

Hearing Astrid’s words, the entire ruined training field seemed to lean forward as one.

Humans, demi-humans, Blessed, support-class trainees, even a few professors who had wandered over out of curiosity—every single one of them went dead silent.

Phones were already half-raised; several recording crystals flickered to life.

Whispers raced through the crowd like wildfire.

"Wait—what’s she gonna say?"

"Did he cheat on her or something?"

"Is this...a breakup?"

"No way, this is way juicier than I expected."

But even as they asked that, most of them were confused as hell.

After all, Mika was support-class.

He was at the bottom of the food chain.

The guy who buffed other people and stayed in the backline praying not to get one-shot.

And Astrid was...Astrid.

A daughter of a Battle Angel.

A walking natural disaster with an elemental affinity so absurd she could probably solo entire SS-class dungeons if she felt like it, even at such a young age.

The gap between them was astronomical.

So, how in the world were they even on speaking terms, let alone close enough for her to be this furious?

What exactly had Mika done for Astrid to even glance his way, when normally no amount of bribes in the world could even make her breath in the direction of someone else.

And yet.

The seniors in the crowd, the ones who had been around longer exchanged knowing glances.

They weren’t shocked. Not really.

They had seen this before.

For some inexplicable reason, the cursed support-class nobody named Mika had wormed his way into the good graces of the Battle Angels daughters.

No one knew exactly how or why.

Some whispered it was blackmail.

Others swore it was a secret blood pact.

A few of the more delusional ones insisted he was secretly their shared little brother from another timeline.

Whatever the truth was, the result was the same.

Astrid, Charlotte, Anya, even Nuri, and the rest treated him with a bizarre mixture of possessiveness, teasing, and occasional murderous rage.

So while the newer recruits gaped in disbelief, the veterans weren’t too surprised when it came to this enigma known as Mika.

Still, curiosity blazed in everyone’s eyes.

They wanted to know what could make Astrid, of all people, this furious.

Because of this, the tension was electric.

Students whispered bets.

Some were half-hoping Astrid would vaporize him on the spot.

But Mika didn’t share their enthusiasm. He instead looked up at her with an awkward half-smile and a sinking feeling in his stomach.

"...Alright." He said carefully. "What exactly did I do, Astrid? What’s got you this angry?"

Astrid’s expression didn’t change.

Her elemental spheres pulsed softly behind her, glowing brighter as her aura grew heavier.

"The reason I’m so angry at you..."

She said slowly.

"...the reason I want to blast you apart right now..."

The entire audience leaned forward in perfect unison.

Phones ready. Fingers trembling over record buttons.

"...is because..."

The pause felt eternal.

"...you called me Astrid instead of Big Sister, like you should have."

She finally said with a slight blush on her cheeks

And in response, no one moved.

A few in the crowd blinked in confusion.

Others rubbed their ears, wondering if they had heard wrong.

A phone even clattered to the ground. Then another.

And then finally—chaos.

"WHAT?"

"DID SHE JUST SAY BIG SISTER?"

"WAIT, WHAT IS HAPPENING?"

"IS THIS SOME KIND OF KINK THING OR—?"

"SHUT UP, SHE’S SERIOUS!"

Even the elite senior students were speechless, not expecting such a reason in a million years.

Mika too stood frozen, a look of utter puzzlement washing over his face.

"You...You want me to call you Big Sister? That’s the big reason?"

"That’s why you’ve been trying to assassinate me and sending projectiles at me for the last ten minutes?"

Astrid’s lower lip actually wobbled.

"Of course, Mika! Why else would I be so angry!"

She cried, voice cracking with genuine hurt.

"I’ve told you so many times—every single time we meet in fact, not to call me Astrid!"

"I told you to call me ’Big Sister’ instead! Big sis! Darling Sister! ANYTHING!"

"But you never do!"

"You always just go ’Astrid this, Astrid that’ like I’m some random person on the street!"

She threw her arms wide.

"How could you?! How could you possibly call your big sister by her first name?! I’m the older one here! I’m supposed to be respected! Revered! Adored!"

"And you won’t even give me the bare minimum of calling me big sis!"

She pointed dramatically at the crowd.

"Ask your juniors! Ask your seniors! They’ll tell you! You’re supposed to treat me with respect!"

"And even if you refuse to give me basic politeness, you can at least call me big sister so I can hear it from your mouth and feel happy!"

"But noooo—you never do!" 𝗳𝚛𝗲𝕖𝕨𝕖𝗯𝚗𝚘𝕧𝕖𝗹.𝗰𝗼𝕞

"No matter how much I beg, no matter how much I cry, no matter how many times I threaten to freeze your toes off—you still just call me Astrid!"

Mika stared at her in dismay.

Then, with mounting incredulity, he shouted,

"OF COURSE I’M NOT GONNA CALL YOU BIG SIS, ASTRID! YOU’RE NOT MY BIG SISTER AFTER ALL!"

Astrid gasped like he had physically slapped her.

"I AM YOUR BIG SISTER, MIKA!"

She shouted back, voice trembling with rage and something dangerously close to tears.

"DON’T YOU DARE SAY I’M NOT!"

"I’ve always been your big sister! From the moment you were born I’ve been your big sister and nothing, literally nothing can change that!"

But Mika was not having any of it, as he threw his hands up.

"You’re literally one year older than me, Astrid! One! Year! There is no way in hell I’m calling someone only one year older than me ’big sis’!"

"That’s embarrassing as hell!"

"That still counts!" Astrid shouted in frustration. "One year is one year! Seniority must be respected!"

The crowd was losing it.

Students were now openly scratching their heads, some recording, others just watching with stunned disbelief.

"You can’t make this up." one boy whispered. "They’re fighting over what? Titles?"

Another girl muttered, "I was expecting murder, not sibling drama."

Meanwhile, Astrid’s patience snapped.

"Fine." She hissed, her aura suddenly surging. "Have it your way."

Dozens of elemental orbs flared to life behind her—flames, ice shards, bolts of lightning, spinning disks of wind and she raised her hand dramatically.

"If you won’t call me Big Sister willingly, then I’ll make you!"

"Wait—what—" Mika didn’t finish before all hell broke loose.

Fireballs exploded around him. Lightning cracked across the field.

Mika sprinted, diving out of the way as Astrid unleashed an all-elemental barrage.

"Call me big sister if you want me to stop!"

Astrid shrieked, hurling a lightning ball that Mika barely dodged.

"Never!" He shouted back, vaulting over a crater.

"Just say it! Two words! Big! Sister!"

"No!"

"PLEASE You’re breaking your sister’s heart!"

"IT’S NOT HAPPENING!"

"Even if you don’t think of me that way, can’t you just say it to make me stop?"

"I REFUSE!" Mika yelled, leaping over a fissure in the ground.

The field was chaos now—explosions everywhere, pillars of earth rising, gusts of wind sending debris flying.

But despite the destruction, it wasn’t a real fight.

It was more like a ridiculous, high-powered tantrum.

The students could only watch, dumbfounded.

One girl whispered, "I thought she was going to kill him."

Another replied, "She’s trying to make him call her Big Sister..."

"Are we...watching a rom-com or a battlefield?"

By now, Mika was running in circles, Astrid chasing him through the air, shouting like a furious older sibling demanding respect.

"Just call me Big Sister!"

"No!"

"Do it!"

"Never!"

"MIKA!"

"ASTRID!"

"YOU SAID IT AGAIN!" She wailed, firing a water cannon that missed by inches. "YOU SAID MY NAME AGAIN! HOW COULD YOU?!"

Meanwhile, the crowd could only stare at the absurdity of it all, as one of the most feared students in Solaria Beyond Academy chased a cursed support student across a battlefield, demanding one simple thing:

"CALL ME BIG SISTER!"
