Jujutsu Kaisen: False Dawn

Creation theory? - Chapter 136

Ren woke, went through the motions—wash face, brush teeth, rinse, spit—then dropped back onto the bed, elbows on his knees, staring at nothing.

"Cursed energy… or cursed tool?"

He clicked his tongue. "Cursed tool. I already have one—the Inverted Spear of Heaven. Even if it's broken, it might still do something. And I've got no clean way to increase my cursed energy without… darker options. That's for later. For now—cursed tool."

He reached for the half‑broken dagger. The remnant of a legend. He pressed cursed energy into it.

It drank.

Too well.

Cursed energy pulsed back through the blade, responding instantly to every push and micro-adjustment he made. As long as he kept feeding it, it sang. The moment he stopped, it was a dead hunk of metal again.

He frowned. "Yeah… it's still a cursed tool. But that anti-technique nullification is either gone… or so weak it barely matters." He turned it over in his hand, feeling nothing but cold steel. "Useless in its current state."

He set it down and glanced up.

Kai2 floated in the air lazily, as if gravity didn't apply to aquatic idiots.

"Hey, Kai. Come here."

The fish drifted over. Ren grabbed its fin and gave it a little shake.

"Why are you still weak? You've been in my shadow for days. Why don't you have a cursed technique? Why haven't you grown stronger?"

He wasn't asking the fish. He was asking himself.

Panda. A cursed corpse. Multiple cores. Intelligence, a body, a will. Cursed energy control. But no innate cursed technique. Not from the cores alone.

"So if Panda had more cores—he'd be stronger, sure. More cursed energy, yeah. But a cursed technique? … No. Cursed techniques are weirder than cursed energy. Anyone can learn to use cursed energy. Techniques are… a birthright. Or a miracle."

He clicked his tongue again, leaning back, thoughts spiraling.

Then an idea hit.

"…Wait. Could I give my cursed technique to Kai2?"

It was ridiculous. But also… technically possible. Kenjaku passed techniques across bodies—through binding vows, memory overprints, and soul‑level swapping. If he could make a vow with Kai2—transfer the pattern, maybe…

"It should be possible. The freak's already bound to me. Loyal pet clause and all that. If I write a new vow on top of it…"

His eyes shifted to the dagger, then back to Kai.

"Which one, though? Flood Maw. It's simple, structured, and water-based. Fits a fish. But can you handle a cursed technique, you little balloon?"

Kai2 blinked back slowly, dumb as ever.

Ren exhaled and fell back flat on the bed, one arm over his eyes. Worm and Kai2 started "playing" again—meaning Worm launched itself and tried to hug Kai2 into submission while Kai2 bobbed up and down like a drunk balloon.

On the other side of the mansion, Mei Mei sat on a couch, phone in hand, texting the higher-ups: Everything is fine. Ren is not causing trouble. He is resting.

Her expression twisted—annoyance, fatigue, something like acceptance.

"Ren this, Ren that. Always him. This brat hijacked my life and turned it into… whatever this is. A mansion in Congo. No commissions. No missions. Getting paid to exist." She paused, staring at the quiet woods through the window. "…Actually… this life isn't that bad."

Ren rolled onto his side, still thinking.

"Hmm, but can I even do that? Give my cursed technique, which was copied to Kai 2? I should be able to do that, right? Hmm, yes, it should be possible… but it would need to be a fair exchange. I would have to transfer my cursed technique for sure; I can't just imprint it… So I would be giving my cursed technique away to Kai2…" and Ren sits up and looks at the inverted sphere of heaven, and something clicks in Ren's mind…

"Ah! Wait, cursed tools are also able to use cursed techniques, like how Nanami's cursed tool works. Nanami used his cursed technique with his cursed tool so much that his cursed tool was, to some limit, imprinted with the Ratio Cursed Technique. So if that's true, then let's say the inverted spear of heaven had a cursed technique imprinted on it too, but it broke since the spear broke in the battle with Gojo and Toji. The cursed technique, which was in the tool, must have also broken apart…

Or weakened? possible… But wait, does this mean I can use the inverted spear of heaven as a base, and Kai 2 could be the cursed energy core, and Flood Maw could be the cursed technique?"
