Kusari
Yubelluna opened with five spells at once.
That was the first useful thing she told me about herself.
The circles appeared around her in a fan of crimson-black light, too smooth to be hurried, too clean to be improvised. Spear. Blade. Blast. Binding line. A second blast held half a beat behind the first so that reacting to one made reacting to the next less clean.
A proper [Queen].
Not the kind of opponent one survived by being proud.
I saw the shape of it before the spells finished forming. Veil Sight bit behind my eyes and the battlefield brightened into ugly clarity—flight path, kill zone, secondary correction, the place she expected me to choose if I dodged like something sensible.
I chose to be elsewhere.
Misstep.
One normal step.
The world rejected the distance for me.
The shift tore worse into my stamina and twisted the air wrong enough that even Yubelluna’s eyes lost me for a fraction. Her first spear went through where I should have been. The second blast crossed the afterimage of my old position. The binding line snapped through empty night.
I came out of the step at the edge of the shattered tennis court, tails spreading behind me by instinct.
Enough of Riser’s peerage had been retired tonight for hiding them to still matter.
Yubelluna corrected her angle in the air and smiled.
“Oh?” she said. “A real little monster after all.”
The sports court behind me was still half-buried in the dead glitter of broken demonic swords.
Yuuto-san’s field of swords had collapsed into fragments.
The paint lines were torn. The fence had been shredded by earlier blasts. The whole place smelled like scorched metal, old ozone, and the remains of too many spells laid over one another.
And under all of that—
Lightning.
Old, clinging lightning.
I narrowed my eyes despite the ache and let Veil Sight deepen just enough to be sure.
There.
Along the inside of her right wing.
Through the edges of two of her still-spinning magic circles.
A drag in the flow between her hands and shoulders.
Residual distortion where Akeno’s power had burned through her earlier.
Not whole, then.
Worn down.
Akeno-san had not lost cleanly.
I planted Stillmark into the broken paint line between us.
The sigil flattened low and dark, almost invisible against the ruined court.
Cold spread beneath my sternum, slower than it once had, a creeping numbness under the breastbone rather than the old sharp spreading chill.
Not for free.
Yubelluna saw none of that.
She came lower, wings cutting the false night.
“Do you know why I’m laughing?” she asked. “Because your little dragon did the smart thing for once. He ran. You’re the one left to be crushed for it.”
“Then stop speaking and do it.”
She stopped for a moment, not expecting that response.
Then she laughed again and dropped another spread of spells into the air.
Faster this time.
No testing.
No taunting.
Real intent.
The first circle spat a torrent of bullets of demonic energy downward to herd me. The second threw a slicing crescent through the space to my right. The third tightened into a spear aimed for my centerline the moment I committed to either.
I used Fox-Glamour first.
Not to vanish.
Only to make the truth of where I stood less exact to the eye.
My outline softened.
The edges of my body breathed wrong in the light.
Her bullets came in half a degree off from where they should have.
Then Misstep again.
The visual wrongness hit her harder now that she was watching for it. I saw the exact instant vertigo touched her—a tiny recoil in the wings, the smallest hitch in altitude, the momentary failure of the eye to trust what the body had just seen.
The space I was at before exploded from her attacks landing.
I came out of the step inside the range she had expected to own and fired Baleful Bolt straight into the half-damaged spell circle nearest her right hand.
The curse-lightning hit with a crack of violet-black force.
Not at her body.
At the structure feeding the rest.
The circle burst.
A shower of red fragments fell away from her magic and the sharp pain answered through my own arm immediately—wrist, forearm, elbow, a bright, punishing line that made my fingers want to curl.
Not locked.
Not yet.
Yubelluna hissed.
A visible twitch of static-ridden distortion ran through the wing Akeno-san had scorched.
There.
She was not only strong.
She was strong and wounded, covering the second part by refusing to concede it in movement.
I smiled before I meant to.
“You’re hurt.”
The expression she gave me after that was no longer amused.
“Everyone is hurt tonight.”
But some injuries mattered more.
She dove.
No more circles floating high and elegant around her. She committed bodily this time, wings folding, one hand driving a condensed spear of demonic light straight toward my throat while the other cast multiple smaller bolts in a low spreading snare meant to catch my legs if I dodged backwards.
Stillmark pulled at the line beneath her.
The mark caught her just enough to drag the timing of the dive wrong.
I moved left.
Not backward.
Left and in.
The snare missed.
The spear grazed my shoulder and tore cloth.
Pain flared hot and immediate.
I answered with another Baleful Bolt from my other hand.
This one at her body.
She twisted hard enough that it only tore through the outside of the damaged wing instead of her ribs, but that was enough.
The bolt cracked through her with a wash of dark lightning and she cried out, altitude dipping again as the old damage from Akeno-san and the new damage from my curse compounded through the same line.
My own arm screamed in answer.
It ached and flexed without my input.
But it was was usable.
Yubelluna pulled back into the air too quickly, rage sharpening every line of her face.
“You insolent little—”
“Quiet.”
I set a second Stillmark where her recovery path wanted to be.
Cold spread slower and broader under my ribs.
My chest had gone numb.
She saw the mar.
She swung wide to avoid it.
Making a strong opponent respect ugly things was its own form of control.
She threw a storm down at me next.
Not precision or elegance.
Volume.
Bullets of explosive demonic energy, slicing wheels of demonic force, each cast meant to turn the ground itself into rubble.
I spread my devil wings and flew through it.
Veil Sight hurt enough now that it felt like needles behind the eyes, but it let me see where the paths were open a second before they would have closed.
I narrowly dodged through gaps.
Some spells clipped my body as I pushed towards her. My already battered body bled more with each spell that landed.
I began to use Misstep when the gaps were too small or sparse.
Misstep tore at my stamina every time I used it, to the point that I was gasping for breath. But every time she watched it happen the disorienting effect touched her just enough to keep her corrections imperfect.
The battlefield got smaller and meaner.
Broken court.
Shattered fencing.
Silver dust from dead swords.
My three tails cutting pale arcs behind me.
Her wings beating overhead, ragged now in the open, even when she tried to hide it.
My wings beating as I hurled myself at her.
I was not stronger than her.
That was not the shape of this.
I was making the fight expensive.
That mattered more.
The first time she actually touched me cleanly, it almost ended it.
A feint high.
A real strike low.
Then the reverse just as I committed to the wrong answer.
Her demonic blast hit my side and detonated.
It threw me down across the cracked tennis court hard enough to take away my breath and stop my thoughts.
I hit the ground badly and rolled through broken paint and debris before stopping on my side.
The world tilted.
For one ugly instant I thought I might not get up.
Yubelluna landed.
That was her mistake.
She thought she had forced me far enough into damage that she could finish it on the ground.
She came in with both hands forward, spell lines already forming to pin and tear and end.
“So all of that and you still ended up in the dirt where you belong.” She scoffed
I accepted the pain.
That was the only choice left.
Not because I am brave.
Because the route to Issei-san and Rias-buchou existed behind me, and if she broke through here then every thing I had used to delay her became worthless.
I had to stop her.
I had to be useful.
So I stopped respecting what my own body wanted.
Stillmark.
Stillmark.
Stillmark.
Three in an instant.
One at her wounded wing.
One half a pace in front of her left foot.
One directly where she would have to drive if she tried to clear all three with a single rush.
Cold spread beneath my sternum.
My chest was no longer just numb.
It now burned when I tried to take a full breath.
Then Baleful Bolt.
Again.
And again.
She was already preparing a spell, but the most impressive aspect of my curse was its speed.
The first blew through the forming spell in her left hand and into her arm.
The second tore the hit the weakened wing harder, crackling through Akeno’s earlier damage until the whole wing limply collapsed.
The third—
The third I should not have cast.
I knew that before I shaped it.
Knew it while my arms shook.
Knew it when sharp pain turned hot enough to threaten the fingers with numb failure.
I cast it anyway.
The bolt hit her center mass just before she crossed the third mark.
The bolt passed through the Stillmark infront of her.
Instead of stringing her, it slammed onto her chest. Far more affective due to it passing through the mark.
Yubelluna screamed..
Her remaining spellwork detonated around her in a shower of broken circles and backlash.
She crashed through the fence, hit the court beyond it, and rolled hard enough that when she tried to rise one wing simply would not answer.
I stood.
Badly.
My left arm hung wrong at my side. Skin red from the overuse of the spell. My had was not fully locked, but close enough that lifting it sent a black flare of pain through the shoulder.
Stillmark’s cold had spread under the ribs and into my sternum until half my torso felt distant and every breath burned.
My eyes ached from Veil Sight hard enough that the whole battlefield carried a bright halo at its edges.
My right leg was painful to move and took more far more effort than normal to use due to the attack that had launched me to the ground.
But I stood.
Yubelluna tried to push herself up.
That meant she was still alive enough for me to finish this properly.
I walked toward her.
Slowly.
Crookedly.
Leaving little flecks of blood on the ground from the wounds she had inflicted on me and the lip I had split at some point in the fight.
She looked up.
For the first time since we began, there was no amusement left in her face.
Only hate.
And understanding.
“You—” She coughed once, hard. “You’re going to destroy yourself before this is over.”
“Yes.”
The answer came easier than it should have.
Because it was true.
Because I had already chosen it.
She tried one more spell from the ground, smaller now, desperate and ugly and nowhere near the work of a proper [Queen]
I pushed the hand she was forming the spell with out of the way as I lowered myself towards her
My one hand found her throat.
Not tightly.
Not enough to crush.
Enough to hold the line.
Baleful Bolt gathered in my fingers one last time.
My arm nearly failed.
I forced it open.
The shot went through her shoulder instead of her heart.
Still enough.
More than enough.
Yubelluna’s body went rigid once, then dissolved into retirement light beneath my hand.
Grayfia’s voice answered over the battlefield.
“Riser Phenex-sama’s [Queen] retires.”
Then there was only me.
And the ruined court.
And the silence after the last enemy in the way had vanished.
I pushed myself upright and stood there for one second too many.
Then my knees almost went with everything else.
No.
Not yet.
I caught myself against the broken fence with my good hand and breathed through the nausea, the cold, the eye pain, th throbbing pain in my leg, the savage line of hurt in my left arm.
Poor shape.
That was the polite phrase for it.
The less polite version was that if anything stronger than a stiff wind met me here, it would finish the work Yubelluna and my own magic had begun.
Still.
The path ahead was open.
I looked toward the new school building and the route Issei-san had taken.
Promotion.
Rias-buchou.
Riser.
The battle had not waited for me to survive this one.
Of course it had not.
I pushed away from the fence, tails low behind me, one hand braced at my side, and began moving.
Not quickly.
Not well.
But forward.
Toward where Issei had gone.
Toward the fight between Rias and Riser.
Toward the next terrible shape the night intended to take.
