Jujutsu Kaisen: False Dawn

"Perfected Red Cursed Circuit" – Chapter 99

I blinked.

Still sitting. Same posture. Same cracked tile beneath me. The sun hadn't moved much, but something inside me had.

Kai2 stirred before I did. The oversized fish snapped upright from its nap like it had just gotten smacked in the face with cursed awareness. It hovered weirdly—uneasy, tail floating behind it like kelp caught in the tide.

I could feel its gaze. Not like usual. Not loyal. Not playful.

It was… staring. No, watching. Like it didn't know what I was anymore.

And I think I knew why.

I moved my hand.

Nothing.

There was no cursed energy leaking out. Not even a sliver. Nothing in the air. Nothing humming. Nothing swirling.

It was like I'd been unplugged from the system.

If Gojo saw me now, I'm dead serious—he'd think he was looking at Toji.

No cursed energy.

At all.

I grinned. Slow. Wide.

"Hah," I whispered. "It works…"

I stood up.

Kai2 floated back into the corner. Still watching. Its little beady fish eyes couldn't decide if I was me or something new entirely.

"Perfected Red Cursed Circuit," I muttered, flexing one hand.

I took a breath in.

And released it.

In the same moment, cursed energy wrapped around me. Full body reinforcement. Total coverage.

But again—

No leaks. No shimmer. No glow.

I looked… normal.

That was the weird part.

My entire body was now hardened in cursed energy. Layered, reinforced, perfected. And I looked like a guy just standing around in a dusty room.

I took a step.

BOOM.

My foot punched a crater into the floor.

I flew.

Too fast.

I almost shot straight out the broken window, but I instinctively grabbed the ceiling—crackkkk!—and I stopped myself just barely before slipping out.

My hand shattered the concrete above me just from the grip.

I dangled for a second in midair.

"…What the fuck?"

I dropped back down.

Dust rained from the ceiling. My heels cracked the tile again on landing.

I blinked slowly.

A perfect boot-shaped dent was where I had stepped.

The ceiling had cracked where I'd caught myself.

I rubbed my neck, dumbfounded.

"…This is normal reinforcement now?"

I was moving like I was in overdrive. Speed. Strength. Precision. All spiked.

I wasn't even trying.

That wasn't a good thing.

I immediately cut the cursed energy reinforcement.

It stopped—like nothing had happened.

Kai2 didn't move.

It still hadn't moved.

It was wedged in its corner, head slightly lowered, staring at me like I'd become an apex predator by accident.

I looked down.

Footprint crater. The floor cracked. The old curtain I'd made was shredded like confetti.

I sat again.

Cross-legged.

Same spot.

Let my hands rest in my lap.

And stared at my palm.

"Okay," I muttered. "Let's see something."

I squeezed.

Tried to push cursed energy out through my fingers. Just a drop. Something.

… But nothing came out.

Huh.

Again.

I pushed harder.

It was actually difficult. Not because it wasn't there—but because it was trying not to come out.

My circuit wasn't just efficient—it was over-efficient.

The flow resistance was insane. Like trying to squirt honey through a needle.

After a second or two—finally—a flicker of cursed energy came out.

But it wasn't blue.

It was red.

I stared.

"…What?"

The glow on my fingertips flickered softly. Blood red. Not a dark crimson like blood pooling on skin—but a clean, luminous, dangerous red.

Almost… like a warning sign.

I didn't even feel heat from it. It just was.

"That's… definitely cursed energy," I said aloud. "Same weight. Same nature. Same pressure."

But red.

Blue was the default color for me. For most people.

But now?

I touched my fingers together.

Still red.

"Is it because the circuit's inside my blood vessels?" I asked no one. "A side effect?"

Made sense. The technique was integrated into the circulatory system. If the red stitch was blood-based, and the whole flow got rethreaded… then yeah, maybe the coloration changed.

Not that I minded.

It looked cooler.

More dangerous.

I stood up again. This time I didn't use cursed energy. Just normal movements. Let the body stay calm.

Kai2 finally let out a little warble. Its tail flicked. It flopped over onto its belly dramatically, like it had just watched a ghost be born.

"Relax," I muttered at it. "Still me."

It didn't move. Just twitched its tail.

I took a deep breath and ran the numbers in my head.

"Okay… Before, I could coat my body with cursed energy for fifteen minutes. That's with the old circuit and my base pool."

Now?

I flexed again. Let cursed energy rise up slowly, like filling a container.

"Feels like… I could do it for an hour now?"

I stared at my hand.

"...Even with the same amount of energy."

That wasn't just efficiency.

That was broken.

"Is that a… 6000% efficiency boost?"

My voice cracked slightly with disbelief.

"I'm sorry—what?!"

I dropped back to the floor, laughing.

Flat on my back.

Legs up in the air.

I couldn't stop.

Kai2 made a weird croak sound and scooted further into the corner.

"I was right… I was right. Holy shit, I was actually right…"

I laughed like a man who just found out the impossible was possible and then built it by hand.

The math checked out. The circuits were stable. The output was fixed.

And now?

Now I had a cursed energy system so airtight, so perfectly routed, that it was like every drop was a nuke waiting to be used.

This wasn't just a red circuit.

This was a bomb that only I could fire.

And even crazier—

It was mine.

Not a copy.

Not someone else's.

Not Rika.

Not some stolen CT.

Mine.

Something I thought of.

Built.

Tested.

And perfected.

And now?

… Now it was done.

Completed....
