Kusari
By the sixth day, the house had learned us.
Or perhaps we had learned it.
The floors sounded different under each person’s step. The sliding doors told on the people who opened them too quickly. The main room carried morning light in a wider band than the side hall. The bathside path held the night’s cool longer than the training yard. The kitchen always smelled faintly of tea even before Hijema-san entered it.
And the people—
The people had become worse.
Not worse in truth. Worse in familiarity.
I woke before dawn to the house around me and knew, without needing to listen long, who was already awake.
Rias first.
Akeno shortly after.
Asia would be the next soft step in the corridor.
Issei would drag himself out of sleep loud enough to imply suffering.
Yuuto would already look composed.
Koneko would appear when she meant to and not one breath earlier.
That was dangerous.
Even more dangerous was that the thought had formed like that at all.
Not Rias-Buchou
Not Himejima-senpai.
Not Argento-san or Kiba-san or Toujou-san.
Only names.
No polite distance.
No reasonable excuse to keep them away.
I sat up too quickly and rubbed a hand once over my face before standing.
The room remained as spare as ever. The danger did not live in the room.
It lived in what my mind had begun to do inside it.
By the time I reached the main room, the morning was already moving.
Buchou stood near the opened veranda with a list in one hand and her hair still partly unbound down her back. Hijema-san was arranging cups. Kiba-san was stretching one shoulder beside the wall, expression calm enough to be irritating. Toujou-san sat with a bowl in her lap, eating in the slow, exact way she did everything. Argento-sanlooked awake in the soft, earnest way she always managed, no matter how hard the previous day had been.
Hyoudou-san looked like the sixth day of training had personally offended him.
That was typical.
“Kusari-chan,” Akeno-san said as I entered, smiling over one shoulder. “Good morning.”
“Good morning,” I said.
Rias-san looked up next. “You’re on time.”
There were many possible responses to that.
I chose the safest. “Yes, Buchou.”
Koneko-chan’s gaze flicked toward me once.
Yuuto-san’s did too, though less obviously.
Perhaps I had answered too quickly again.
Breakfast was brief and functional by necessity, though Issei-san still found time to mourn the fact that meals no longer counted as sanctuary between rounds of suffering.
“This is psychological warfare,” he said around rice and complaint. “The food is too good. It makes me think life is worth continuing, and then training starts.”
Hijema-san smiled. “I’ll take it as a compliment to my cooking.”
“It’s evil.”
“We’re Devils,” Koneko-chan said.
“I’m aware!”
Argento-san hid a laugh in her cup.
Kiba-san didn’t quite manage to hide hers.
I kept my eyes on my bowl.
Every small thing had become dangerous.
After breakfast, the house emptied into the mountain air and the day began properly.
The first hour was formation work.
Buchou had them drilled through movement lines, retreat lines, exchanges, and support position changes again and again until the patterns became second nature, enough to be useful. Issei-san still wanted to push too directly. Asia-san still favored him when the lines split. Kiba-san corrected with exact precision. Toujou-san corrected with impacts. Akeno-san corrected by making everyone else more nervous simply by smiling when they got it wrong.
My place in the structure had changed over the last few days.
Not in title.
Not in rank.
Rias-san now set my position in the line with confidence instead of caution. Yuuto-san began choosing routes that assumed I could place Stillmark where she needed it. Koneko-chan no longer looked surprised when I took an angle she expected. Asia-san had started glancing toward me in transition moments not because she feared something was wrong, but because she expected I was part of the answer.
That was all dangerous.
Stillmark had improved enough to be useful without ceremony now.
I set one in the dirt ahead of Toujou-san and felt the familiar reaction answer under my breastbone: a cold, spreading numbness working outward from the center of my chest like a slow ring beneath the skin.
Smaller than Baleful Bolt.
Sharper than it looked.
Easier to use because of that.
Koneko-chan—
Toujou-san crossed the marked point, adjusted, struck, and drove Issei out of line hard enough that he almost tripped over his own recovery.
“That one was almost mine” he protested.
“No,” Toujou-san said. “It wasn’t.”
Kiba-san, passing just behind him with her sword lowered, added mildly, “You’re figuring it out.”
“That sounds like an insult.”
“It is mostly approval.”
Issei-san looked annoyed.
I turned away before any expression could form on my face.
Later, while Himejima-san and Argento-san worked support timing under Buchou’s eye, Yuuto-san joined me for the next run.
“Again,” she said.
I nodded.
Stillmark took more cleanly against packed earth than stone. Better in transition lines than directly under a standing target. Best when set where certainty would become commitment.
I placed it.
Yuuto-san moved.
Her strike line corrected itself through the marked point almost invisibly, turning a decent angle into a better one.
She lowered the practice sword. “There.”
“Yes.”
“You can place it faster.”
“It degrades if rushed.”
“You can still place it faster.”
That answer fit her.
Annoyingly correct.
I set the next one before she finished speaking.
The cold numbness spread again, a little farther this time, brushing the ribs before retreating.
Yuut—-
Kiba-san noticed my hand touch lightly once at the center of my chest.
“Worse?”
“Not enough to matter.”
She gave me a look.
Not severe.
Not soft.
Just the exact sort of look that meant she had understood both the answer and the evasion at once.
“Then let it matter when you need to,” she said.
Before I could decide whether that counted as concern or instruction, Hyoudou-san made a noise from across the yard that suggested either injury or dramatic resistance to instruction.
With him, both were possible.
We looked over.
Himejima-san had him back at the low worktable.
There were vegetables on it again.
Of course there were.
He caught me looking and pointed accusingly across the yard.
“She’s doing real magic and I’m still getting bullied by potatoes!”
“That sounds pitiful.” I said.
His face did something outraged and wounded at once.
Yuuto-san’s mouth curved.
I did not focus on that either.
The training blocks broke and reformed through the morning, then into early afternoon. Rias-san drove pace into everyone. Akeno-san drove Issei-san forward, he was determined but making an odd face. Koneko-chan continued reducing him to useful pieces. Asia-san was better than she had been three days earlier and knew it just enough to be embarrassed by that too.
And Issei—
Hyoudou-san was changing as well.
Not enough.
Not gracefully.
Not in a way anyone could admire from a distance.
But changing.
His stance under Kiba-san’s correction was cleaner. He no longer lost himself quite so easily the second Toujou-san broke his rhythm. His demonic control still behaved like a bad joke told by a hormonal idiot, but it had stopped being completely useless.
That was probably the true problem with training.
It made even slow improvement visible.
By midafternoon, the drills shifted.
Akeno-san declared that Issei-san had “finally reached a stage worth inflicting on other people.”
No one should have been reassured by that phrasing.
No one was.
She gathered us to the wider side of the training yard where one of the old practice posts had been fitted with a borrowed shirt and outer layer tied around it in a parody of a clothed target.
Hyoudou-san stood in front of it, red-eared, trying to look proud and not indecent at the same time.
He was failing in exactly the way he always did.
“What is this?” Koneko-chan asked.
Akeno-san folded one arm beneath her chest and smiled brightly. “A milestone.”
Buchou looked less convinced. “This is what you’ve had issei working on? Is he ready?”
“He wont fail,” Himejima-san said. “I think.”
That last part did not improve matters.
Asia-san’s face was already pink.
Kiba-san stood to one side with her arms folded, looking practical and faintly resigned.
Toujou-san looked ready to call the entire thing disgusting before it began.
I stood near the outer edge of the group, close enough to see, far enough to leave if the scene became stupider than I could bear.
That last part was a mistake.
Akeno-san tilted her head toward Issei-san. “Go on, Issei-kun. Show us your progress.”
He swallowed, then straightened with all the doomed pride of a boy about to prove himself with a spell born from shamelessness.
“It’s not perfect yet,” he said. “But I got the shape of it.”
Koneko-chan’s expression flattened. “…That sentence is already bad...”
He pointed at the dressed training post. “The idea is stripping away the outer layer with focused demonic power. Removing it.”
“Like the potatoes,” Asia said softly.
“Yes,” Issei said, then looked at her and turned red for reasons that had nothing to do with magic. “I mean—yes, like the potatoes.”
Akeno-san laughed.
Yuuto-san looked away.
Koneko-chan made a sound of quiet disgust.
Rias-buchou folded her arms and sighed. “Issei-kun…. Fine. Do it.”
Issei-san inhaled slowly.
The air around him shifted.
Not dramatically at first. Just enough that I could feel his demonic power gathering into a thinner, stranger edge than usual. Not built for impact. Not built for raw force. Something more specific and more embarrassing than that.
Akeno-san’s eyes sharpened with interest.
“Good,” she murmured. “That shape.”
He thrust one hand toward the training post.
“Dress Break!”
The spell took.
For one instant the magic flashed in a narrow wave, pale and violet-red at once. It crossed the distance between him and the post in a clean line, caught the outer layer, and—
Stripped it.
Not burned.
Not peeled away.
Burst it.
The borrowed shirt and outer layer was shredded from the post and fluttered down in humiliatingly small pieces.
Silence.
Then Akeno-san clapped once, delighted. “There.”
Issei-san’s entire face lit.
It was the proudest I had seen him look all week.
“I did it,” he said, a little breathless. “I actually did it.”
Asia-san looked shocked and impressed at once.
Yuuto-san nodded once, practical as ever. “The control looked good.”
Koneko-chan looked unconvinced by the utility and deeply convinced of the indecency.
Rias-san’s expression stayed exasperated, but I could see the calculation in it now. Something that stripped away equipment, uniforms, or protective layers without damage had combat value whether one liked the origin of it or not.
Hyoudou-san, drunk on success and female attention in equal measure, made the obvious mistake.
“I can do it cleaner,” he said.
Himejima-san, being Himejima-san, should have stopped him.
Instead her smile widened. “Then show us.”
That was the moment the test should have ended.
It did not.
Issei-san shifted, still flushed with victory, still feeding off the thrill of having made something real. His power gathered again, rougher this time because the success had excited him more than the concentration had steadied him.
I felt it change before the others did.
The first cast had been narrow.
This one was hungry.
I stepped half a pace sideways to clear the angle.
Another mistake.
He threw the spell.
“Dress Break!”
The wave left his hand.
It should have gone to the stripped post.
Instead it broke wide.
Not a complete wild cast. Not enough to miss everything. Enough to lurch when his attention flickered, enough to catch on the nearest valid line of cloth and body instead of the target he wanted.
Me.
The impact was not painful.
That made it worse.
One second I was watching the spell split wrong.
The next, the top portion of my training clothes pulled open and away with a sharp, unnatural release of tearing fabric.
The world did not stop.
I did.
It happened too quickly for thought.
Too quickly for anger.
Too quickly for embarrassment.
Too quickly for anything that belonged to the present.
The clearing disappeared.
Not physically.
Only in meaning.
The mountain air.
The training yard.
The peerage.
The sixth day of camp.
All of it fell away beneath something older and more efficient.
Clothing loosened.
Order given.
Decisions made for me.
Continue.
My hands moved before I told them to.
To obey the logic already set in motion and finish what had begun.
Somewhere very far away, someone said my name.
I only heard the memory of a command I had been given.
I remembered what was expected of me and what would happen if I did not obey.
My fingers found the remains of my clothes automatically.
The shape of the world around me had gone thin and white and wrong, every sound distant except the one that mattered most:
what happens next when you are expected to continue.
I looked up.
Rias was there, standing close to me.
No, not Rias.
The answer arrived from a place deeper than choice.
“Mistress,” I heard myself say.
The voice did not sound like mine.
“Should I continue?”
Everything in the clearing died at once.
Only the silence after the wrong question remained.
