If the universe wanted me dead, it probably should've sent a meteor.Or a black hole.Or an IRS letter addressed to me personally.
Instead, it sent her.
The third arrival.
And unlike Ami—my overprotective, angelic blade-goddess—or Yergba—the chaotic gyaru of cosmic attitude—this one wasn't here to join the household.
She was here to destroy it.
✦ Act I: The Arrival
It was 2:42 a.m.I only knew that because my phone buzzed violently until I woke up face-first in my pillow, drool still wet on my cheek.
[INCOMING THREAT DETECTED][CLASS: HUNTER][TARGET: SUMMON PAIR]
My stomach turned to stone."Hunter…?"
Before I could even blink—
CRASH.
The entire apartment shook like someone punched the building with a kaiju-sized fist.
Ami shot awake instantly—no disorientation, no hesitation.Sword materialized.Aura surged.
"Aki, get behind me!" she commanded, voice sharp with battle instinct.
Yergba was on her feet even faster, hair messy but eyes blazing.
"The hell was that?!" she shouted, summoning golden chaos energy around her fists.
Another BOOM.
This one closer.Much closer.Like two feet from the front door.
My heart hammered against my ribs like it wanted to break out and evacuate without me.
Ami switched into kill-mode, stance low and perfect.Yergba cracked her knuckles with a grin that said finally something fun.
Then—
The door exploded off its hinges.
Not kicked.Not blasted.Ripped off.
A figure stepped through the drifting smoke.
A girl.My age.Maybe shorter than Ami, taller than Yergba.A tank top. Baggy cargo pants. Combat boots.Short, messy black hair.Freckles.A scar across her jaw like she'd been in real fights, not magical anime stuff.Eyes sharp, wild—like an apex predator who wasn't here to chat.
She looked… human.Completely human.
But the aura around her?
Deadly.Wrong.Predatory.
Ami inhaled sharply.Yergba stopped grinning.
"Hunter," Ami whispered, voice trembling with recognition. "A real one…"
The girl cracked her neck, rolled her shoulders, and spoke in a low, dangerous voice.
"Name's Sam."She pointed directly at Ami and Yergba."You two are illegal summons. And I'm here to delete you."
✦ Act II: The First Strike
Ami reacted first.
"GET BEHIND ME, AKI—!!"
Sam moved faster.
Way faster.
One second, she was standing in the doorway.The next, she was already in front of Ami—right arm pulled back, glowing crimson with some kind of awakened human energy.
Ami blocked with her sword—
CLAAAAANG!
The shockwave obliterated the kitchen table.
I flew backward.Yergba caught me mid-air with one hand.
"Bro, she hits like a satellite crash," Yergba muttered.
Ami gritted her teeth, pushing against Sam's fist.Her knees almost buckled.
That alone was terrifying.A cosmic entity—my level 10,000 summon—getting overpowered by a teenage girl?
Sam smiled.It wasn't a kind smile.It was the smile of someone who loves fighting.
"You're strong," Sam said. "Good. Weak summons are boring."
Then she twisted, elbowed Ami in the gut—
THUD.
Ami coughed, stumbling back.
"Ami!!" I screamed.
Sam didn't even wait.She pivoted, launching toward Yergba next.
Yergba shoved me aside."Sit down and cry later— I GOT THIS."
She coated her legs with swirling gold energy and kicked.
Sam blocked with her forearm.The impact flashed like lightning.
BOOOM—!!
The shockwave blew out the living room windows.
I shielded my face, coughing.
Yergba flew back, slamming into the wall so hard the plaster cracked around her silhouette.
She wiped her mouth and spat blood.
"Ohhh she hits HARD.I like her."
"Yergba, PLEASE take this seriously!!" I cried.
Sam cracked her knuckles."You two talk too much. Summons should die quietly."
"HEY," Yergba barked. "Rude."
Before she could move again—
Ami reappeared like a beam of light, swinging her blade downward with divine force.
Sam grinned and caught the blade WITH HER BARE HAND.
Ami gasped."That's impossible—!!"
Sam squeezed.
The sword cracked.
My heart stopped.
"Your powers don't work fully here," Sam said. "Human realm nerfs you. Me? I get buffed."
Ami's eyes widened with panic.
Sam lifted her, slammed her into the floor—
WHAM.
The entire apartment shook.Ami cried out— a sound I'd never heard from her.Raw.Pained.
I ran toward her without thinking.
"Ami! AMI!!"
Sam grabbed me by the collar mid-run and threw me backward like I weighed nothing.
"Aki!!!" Ami screamed.
I hit the floor so hard stars exploded behind my eyes.
Yergba's voice snapped with fury."Oh hell no— you do NOT touch him."
Golden energy surged around her.Her aura intensified, twisting and pulsing like a living beast.
She charged Sam—
—but Sam ducked under her swing, grabbed her wrist, spun, and launched Yergba straight through the sliding door.
Glass shattered.Yergba flew off the balcony.
My heart collapsed.
"YERGBA!!!!!"
A second later—
A swirling explosion of gold energy erupted outside.Yergba floated back up into view, body wrapped in blazing golden fire.
She wiped her nose, eyes burning like suns.
"Oh it's ON."
✦ Act III: Cosmic vs Human
Ami stood shakily, clutching her cracked blade.Her hair shimmered with panic.
"She's too strong," Ami whispered. "I cannot sense her limits— she has none."
Sam cracked her knuckles.
"You two ready to die together, or one at a time?"
Yergba snarled."Try me, Tomboy Terminator."
Ami tightened her stance."I will protect Aki with my life."
Sam smirked."Oh good. I love a challenge."
Then all three of them moved.
What followed was chaos.
Ami blurred and sliced the air, her blade leaving trails of blue light like falling stars.Sam dodged every hit with terrifying precision—leaning, twisting, flipping.She moved like she'd fought hundreds of summons.
And maybe she had.
Yergba launched golden energy blasts that cracked the pavement outside, each one exploding like miniature suns.Sam weaved between them effortlessly, like she was dancing.
Then Sam retaliated.
She dashed forward, wind exploding behind her.She landed a fist on Ami's stomach—
THUD.
Ami slid backward several meters, nearly collapsing.
Yergba kicked Sam in the jaw—Sam grabbed her leg—Spun—Slammed her into the railing so hard metal bent like cardboard.
Yergba coughed, wheezing."Holy crap— She hits like God playing baseball."
Ami wiped blood from her lip."There is something unnatural strengthening her—some ability…"
Sam shrugged."Yeah. It's called training."
Then she lunged.
✦ Act IV: When Hunters Don't Miss
Sam was unlike any enemy they'd faced.
Hunters weren't cosmic beings.They weren't summoned.They weren't supernaturally blessed.
They were humans.
Humans who fought gods.
And somehow won.
Sam parried Ami's sword with her forearm, punched Yergba in the ribs, elbowed Ami across the jaw, and kicked Yergba through a wall.
"Ami—Yergba—STOP FIGHTING ALONE!" I yelled. "You need to work together!"
Ami froze for a microsecond.Yergba did too.
Sam took advantage instantly.
She dashed at Ami, fist glowing red—
But Yergba blocked the punch, arms crossed, golden aura shielding her.
The explosion rocked the balcony.
Yergba grimaced. "Ow— that HURT."
Ami slashed from the side, forcing Sam to dodge.
For the first time—
Sam frowned.
"Oh? Teamwork?"
Ami exhaled shakily. "Aki is right… We must fight as one."
Yergba smirked. "About damn time."
They moved.
Together.
Ami's blade danced with blinding speed—Yergba's golden chaos energy blasted from every direction—Sam blocked one, dodged the other, but she couldn't keep up with both.
Ami struck her across the leg—Yergba hit her with a spinning kick—Sam staggered, surprised for the first time.
"Tch… annoying."
She backed up, panting lightly.
"You two aren't normal summons. You're… stronger."
Ami pointed her cracked sword at Sam."You cannot harm Aki."
Sam wiped blood from her lip.
"I don't want to harm him."Her eyes sharpened."I want to save him."
My heart froze."What— what are you talking about?!"
Sam looked straight at me.
"You're a Keeper, right? You think that's a blessing?"She shook her head."It's a curse. A leash. The more summons you get, the closer you get to death."
Ami stiffened.Yergba froze.
"What…?" I whispered.
Sam's voice dropped to a near-growl."I'm here because the next arrival won't be friendly like these two. It'll kill you. And then the world."
Ami trembled."…Lies."
Sam looked at her with raw, human fury.
"I WISH I was lying."
The night air chilled.
Yergba swallowed, expression finally losing its smugness."What are you saying…?"
Sam held up her palm.
A symbol flickered.The mark of a Hunter.
"I'm not here to kill you," she said quietly. "I'm here to stop the summon that's coming."
Ami's sword flickered uncertainly.
Yergba's aura dimmed.
I stepped forward, voice shaking.
"Sam… if you're not here to kill them…"
Sam looked at me—really looked at me, her eyes raw and exhausted.
"I'm here to protect you, idiot."
Something in my chest cracked open.
Ami whispered, "Hunter… protecting a Keeper? That is forbidden…"
Sam shrugged.
"Yeah. And?"
Yergba blinked. "Girl, you're insane."
Sam smirked tiredly."You have no idea."
Then she collapsed.
Not from defeat.Not from retreat.
From exhaustion.
Face-first onto the balcony.
I ran to her.
"SAM!!"
She groaned."Don't shout… I'm tired… and your apartment sucks…"
And then she passed out completely.
Ami stared.
Yergba stared.
I stared.
My life was falling apart like a wet tissue.
And yet—
I gently lifted Sam's head into my lap.
This girl risked her life fighting monsters stronger than gods…just to protect a boy she didn't even know.
Ami whispered, voice trembling, "Aki… what shall we do with her…?"
I swallowed hard.
"We take care of her."
Ami blinked.
Yergba stared at me like I'd grown a second head.
"She's dangerous, Aki," Ami whispered. "More dangerous than either of us."
"I know," I said softly.
Sam slept, breath shallow, bruises blooming on her skin.
"But she protected me.She risked everything."I looked at Ami and Yergba."We can't abandon her."
Ami lowered her gaze.
Yergba sighed dramatically."Bro, we're gonna need a bigger apartment."
And just like that…
A new chaos entered my life.
A Hunter.A warrior.A human stronger than gods.
And whether I wanted it or not—
She was now part of us.
