Chapter 18: Non-Uniform Response

The bell rang, sharp and precise, cutting cleanly through the last line of the lecture like a blade.

Chairs scraped in a controlled wave, fabric rustling, books closing, voices rising in polite layers rather than noise. The room went from stillness to motion in seconds.

I finished the final note in my notebook before closing it carefully. The habit had become automatic: finish the thought, align the pen, stack the pages.

I like the routine.

Misaki had slipped out a few minutes before the bell — some “obligation” she hadn’t bothered to explain. That meant I was on my own for the walk back, which I didn’t mind. Being alone in a crowd felt different from being alone in silence. Safer, somehow.

I slid my bag over my shoulder and stepped into the hallway with the rest of the class.

The corridor was bright with afternoon light, tall windows casting long rectangles across the polished floor. Students flowed around me in orderly clusters, conversations already drifting toward homework, tea plans, committee duties.

And then—

The air prickled.

I slowed instinctively.

Leaning against the wall near the windows, arms crossed, looking both completely out of place and perfectly confident about it, was Misaka Mikoto.

She wasn’t trying to blend in. She never did.

A few students passed her with wide arcs, precise distance maintained, whispers trailing behind them. Tokiwadai Level 5s weren’t just celebrities — they were weather patterns. You didn’t ignore them; you planned around them.

Her gaze lifted and locked onto me immediately.

So she had been waiting.

My stomach tightened, but not from fear. Anticipation. Curiosity.

I walked toward her.

“Hi,” I said, stopping a few steps away.

Direct felt safest.

She pushed off the wall, straightening. Up close, the air around her felt denser — not actively threatening, just… charged. Like standing near an electrical transformer; you could almost hear the buzz.

“We need to talk,” she said.

No greeting. Just blunt intent.

“Okay,” I replied.

Her eyes flicked past me briefly, scanning the hallway, then returned.

“Not here.”

I nodded. “Lead the way.”

We walked in silence.

She moved quickly but not hurriedly, taking turns with the confidence of someone who knew exactly where she was going and didn’t feel the need to explain.

Out of the main building. Across a side courtyard. Past a row of practice fields that were empty at this hour.

Finally, she stopped near an open training ground — one of the reinforced areas used for ability development. Concrete surfaces, metal structures, minimal decoration.

Safe for destruction.

She turned to face me.

Up close, her expression wasn’t angry.

It was intent.

“I’m just going to ask this once,” she said. “What are you?”

Not who. Not what’s your ability.

What are you.

I considered my answer carefully.

“A student,” I said.

Her eyebrow twitched. “You know that’s not what I mean.”

“I figured.”

A breeze moved across the field, tugging at our uniforms. The space felt too open, too exposed — like the world had stepped back to give whatever was about to happen room.

She studied me for a long moment.

“When we touched yesterday,” she said, “you felt like an Electromaster.”

My pulse quickened despite myself.

“Only for a second or two,” she continued. “Then nothing. Like someone flipped a switch.”

I didn’t respond.

“If you’re hiding your ability,” she said, “fine. Lots of people do. But you didn’t hide it — it disappeared.”

Her eyes sharpened.

“That doesn’t happen.”

I swallowed. “Maybe you were mistaken.”

“I wasn’t.”

No hesitation. Absolute certainty.

Silence stretched between us, thin and tense.

Then she exhaled sharply, running a hand through her hair.

“Look,” she said, tone shifting. “I’m not here to report you or anything. I just want to know what I’m dealing with.”

That phrasing again.

Not hostile. Cautious.

“I don’t fully understand it myself,” I said quietly.

Which was the truth.

She searched my face, probably looking for signs of deception. Whatever she saw seemed to satisfy her, because her shoulders loosened slightly.

“…Fine,” she said. “Then we do it the simple way.”

A small spark snapped between her fingers.

“Show me.”

My breath caught.

“You want me to demonstrate?”

“I want to spar,” she corrected. “Lightly.”

Lightly. From a Level 5.

“I won’t hurt you,” she added, misreading my hesitation.

That wasn’t what I was worried about.

I was worried about hurting her.

Not because I thought I could overpower her — that would be ridiculous — but because my ability didn’t always care about intent.

Still…

This was Misaka Mikoto.

If anyone could handle it, it was her.

And a part of me — a very large part — wanted to see her power up close. Not through secondhand memory or distant observation, but directly. In motion. Real.

“…Okay,” I said.

Something like approval flickered across her face.

She stepped back, creating distance, posture shifting subtly — weight balanced, knees loose, hands ready. Not a formal stance. A practical one.

Experienced.

“Rules,” she said. “No lethal attacks. Stop if I say stop. If you can’t control something, don’t use it.”

I nodded.

“Same for you,” I added quietly.

She smirked. “Fair enough.”

The air stilled.

For a heartbeat, nothing happened.

Then—

Static crawled across my skin.

Not touching me. Surrounding me.

Her power was ramping up, not explosively but steadily, like a generator spinning to life. The electromagnetic field around her thickened, invisible lines bending the environment in ways only an Electromaster could feel.

My own ability responded instantly.

Resonance.

Patterns forming. Structures mapping. Possibilities unfolding like blueprints in my mind.

Electricity.

I let it in.

A faint crackle danced along my fingertips, weaker than hers — imitation, not replication.

Her eyes widened slightly.

“…So I wasn’t imagining it,” she murmured.

She moved first.

Not a full attack — a test. A small bolt snapping across the distance between us, fast but controlled, aimed to miss unless I failed to react.

I raised my hand instinctively.

The electricity bent.

Redirected — grounded into the reinforced floor in a scatter of blue sparks.

Surprise flashed across her face.

“Okay,” she said softly.

She stepped forward, faster this time, another discharge following, then another — probing, mapping my responses the way I was mapping hers.

I moved without thinking, body guided by patterns more than decisions. Each strike felt predictable a fraction of a second before it happened, like seeing the lightning before actually hearing the thunder.

I redirected. Deflected. Dissipated.

Not perfectly.

But successfully.

Her expression shifted from curiosity to focus.

A third bolt came — stronger.

Pain flared through my arm as I grounded it, muscles locking for a split second. My knees bent instinctively to absorb the shock.

Okay. That hurt.

Good to know.

She noticed.

“You can stop anytime,” she said.

“I’m fine,” I replied.

And I meant it.

Because beneath the pain, beneath the strain, something else was rising.

Clarity.

For the first time, I wasn’t reacting to random stimuli or uncontrolled contact. This was structured input. A system I could analyze in real time.

I took a breath.

Then stepped forward.

Electricity flared around my hand — brighter than before, denser, compressed. Not at her level, not even close, but far beyond what I’d shown so far.

Her eyes widened again.

“Oh,” she said.

Not fear.

Interest.

And just like that, the spar stopped being one-sided.

She smiled, unmistakably excited.

“Now we’re getting somewhere.”

She moved first.

Not a single bolt this time.

A spread.

Electricity erupted from her in a fan-shaped burst —  aimed at everything. Branching arcs forked through the air like a living net, each strand snapping toward a different trajectory, converging on the space I occupied rather than my body itself.

My brain didn’t even try to calculate a safe block.

There wasn’t one.

If I stayed where I was, at least three of those would hit. Grounding one would leave me open to another. Trying to absorb them would overload my nerves.

Electricity wasn’t the answer anymore.

So I dropped it.

Resonance shifted.

Kinetic self-adjustment.

At most Level 3.

It only affects me, but that was more than enough

The moment it engaged, my body stopped feeling like a single object moving through space and started feeling like a collection of vectors I could nudge independently. Tiny corrections layered on top of normal motion.

I stepped sideways.

My center of mass shifted mid-step, momentum redistributing before my foot even touched the ground. Instead of planting and pushing off, I slid laterally as if friction had been briefly edited out of existence.

The first bolt passed where my shoulder had been.

I dropped low.

Not a crouch — a sudden vertical collapse, like gravity had doubled for half a second. My knees hit the concrete hard enough to sting, but the momentum bled away before it could transfer into my spine.

Two arcs cracked over my head, close enough to burn the air.

I pushed off the ground.

Except there was no push.

My body accelerated upward without the usual coiling of muscles, inertia rewritten just enough to convert stored kinetic energy into vertical lift. It felt like being yanked by invisible strings attached to my bones.

Pain stabbed through my ankles anyway.

It was a hard power to control.

The landing was worse. I came down too fast, internal dampening lagging behind the sudden mass correction. The impact rattled my teeth, shock shooting up my legs before the field caught up and bled it into the ground.

Another bolt hit where I’d been standing an instant earlier, concrete exploding into dust and fragments.

Mikoto’s eyes narrowed.

“You’re not speeding up,” she said, almost to herself. “You’re… shifting inertia.”

A second wave came, tighter this time.

I pivoted.

My upper body rotated first, hips following half a beat later as angular momentum redistributed across joints that weren’t meant to move independently. It felt deeply wrong, like twisting out of my own skeleton.

The electricity skimmed my sleeve.

Heat lanced through fabric, skin sizzling beneath it.

Too close.

Too many trajectories.

Each adjustment cost something — muscle strain, joint stress, micro-tears accumulating faster than my body could compensate. My breathing grew sharp, ragged, chest burning from oxygen debt.

It wasn’t graceful, but it was working.

A wide bolt struck the ground beside me, detonating into a shockwave that lifted me off my feet. I twisted midair, dumping rotational energy into forward motion, converting what should’ve been a tumble into a sliding landing.

My palms scraped raw against the concrete.

Blood smeared across the surface.

Mikoto stopped.

She was thinking.

"How are you changing your movement like that? are you using some kind of magnetism, but how?"

I forced myself upright, legs trembling from accumulated strain.

Does she still think I'm only an electromaster? Anyway, that is basically what I'm doing anyway, just not with electromagnetism.

“Something like that.” I said

She stared at me — Intrigued.

Then she smiled.

“Okay,” she said quietly. “That’s actually cool.”

Her expression hardened.

“But let’s see how long you can keep it up.”

The air pressure shifted.

Static crawled across every exposed surface as charge density climbed sharply, the field around her thickening into something almost tangible. My skin prickled as ions in the air polarized, hair lifting slightly from the buildup.

Oh.

That was bad.

Multiple attack vectors formed simultaneously, each one compressing into a discrete discharge point. A coordinated burst, timed to eliminate escape windows.

I moved before she released it.

Because I could feel the structure forming, AIM patterns tightening like muscles about to contract.

The ground under my feet fractured as I launched sideways, inertial compensation pushing past its safe limit. My vision tunneled briefly, blood pressure lagging behind acceleration.

The bolts came anyway.

A storm.

Electricity tore through the space I’d occupied, then chased me across the field, arcing unpredictably as magnetic fields bent trajectories mid-flight.

No clean path.

Only less bad ones.

I zigzagged, momentum shifting violently between directions, joints screaming in protest. My shoes shredded against the concrete as friction spiked and vanished in alternating bursts.

One arc clipped my thigh.

Pain detonated instantly, muscles locking, leg nearly collapsing out from under me. I forced a correction, dumping forward momentum into a stagger instead of a fall.

Another bolt grazed my back, heat searing through fabric.

I couldn’t keep this up.

Prediction only worked when there were gaps.

She wasn’t leaving any.

So I switched again.

Resonance shifted violently, kinetic patterns collapsing as I reached for something flashier.

Pyromancy.

Flame ignited in my palms, oxygen ripping into combustion in a tight, compressed sphere. High-temperature plasma, shaped by instinct more than finesse.

I thrust both hands forward.

Twin fireballs roared outward, aimed at the ground in front of her. The explosions sent superheated air and debris upward, distorting line of sight and disrupting the conductive path her electricity preferred.

She didn’t expect it.

Her stance faltered for a fraction of a second — enough to break the rhythm of her attack pattern.

Surprise flashed across her face.

“Fire !?”

That was when it happened.

Reflex.

A stronger discharge surged from her hand, compressed tighter than the others, drawn from deeper reserves before she consciously reined it in.

Too much power.

The bolt crossed the distance instantly.

It hit my shoulder and exploded through my torso in a blinding flash of white-blue light.

My body lifted off the ground like a rag doll, nerves overwhelmed by a surge far beyond what they were designed to transmit. Every muscle contracted simultaneously, spine arching violently as current forced its way through the path of least resistance.

Pain didn’t register as sensation.

But as a blank, searing void where normal perception should have been.

I hit the ground hard enough to drive the air from my lungs, skidding across the concrete until friction finally stopped me. The world snapped back in fragments — ringing ears, burning skin, the metallic taste of blood flooding my mouth.

My arm wouldn’t move.

Neither would my left leg.

Somewhere nearby, electricity crackled weakly, residual charge discharging into the ground.

Mikoto stood frozen.

Her eyes wide.

“…I didn’t—”

She stopped herself, horror replacing the adrenaline high.

“Hey,” she said sharply, stepping forward. “Hey. Stay with me.”

I tried to respond.

Only a broken gasp came out.

My vision blurred, darkening at the edges as shock set in. The pain arrived late but all at once, a tidal wave of burning agony radiating from the impact site through every nerve in my body.

And beneath it—

Something else stirred.

My skin prickled as warmth spread outward from the center of the damage, like countless microscopic threads knitting tissue back together whether it wanted to cooperate or not.

Mikoto’s eyes widened further.

“…What is that?”

Light flickered faintly beneath my skin, not bright enough to illuminate the ground but unmistakable against the dusk.

Healing.

I sucked in a shaky breath as sensation returned in jagged pieces, muscles spasming as they restarted one by one. My fingers twitched, scraping weakly against the concrete.

Barely Alive.

Mikoto didn’t move.

For the first time since I’d met her, she looked genuinely unsure of what she was seeing.
