The Null Zone pulsed with tension. What was once a realm of stillness—of echoing silence and unbreakable void—now trembled. Three figures floated in its center: Goku, Luffy, and Yuji. Around them, the space cracked and warped as if rejecting their presence.
Yuji tightened his fists, Sukuna's markings burning faintly along his cheek. "Something followed us."
"No kidding," Luffy muttered, his eyes darting toward a spiraling tear in the darkness. "It doesn't feel like cursed energy. Or haki. Or ki. It's… something else."
Goku's gaze sharpened. "It's the Beast."
The rift widened, and from it emerged a creature unlike anything they had seen. It was vast, shifting between forms—part shadow, part flame, part machine. Its many eyes blinked in chaotic rhythms, and its body pulsed with stolen energy: cursed symbols etched into a Saiyan skeleton, armored with chakra-forged plates and trailing haki mist.
"It's absorbing power from every system," Yuji said grimly. "It's not just a beast. It's a fusion."
The Null Beast roared—a soundless tremor that shook the zone. Fractured echoes of other realms blinked behind it: the Hidden Leaf burning, the Grand Line sinking, planets crumbling in flashes of silver.
"We can't let it leave this place," Goku said. "If it escapes…"
Luffy cracked his knuckles and grinned. "Then we hit it hard enough it forgets how to exist."
Yuji flared with cursed energy. "Let's go."
Goku launched first, vanishing and reappearing above the beast's head. A strike of Ultra Instinct landed clean—but the beast reformed instantly, its body folding inward and sprouting a second set of arms.
"Right. It adapts," Goku muttered.
Luffy activated Gear Fifth, laughter warping the void. He grabbed the air itself, stretching a black hole into a slingshot and launching himself at the creature. His punch turned the Beast inside out—only for it to reverse time briefly and reform.
Yuji summoned Rika.
The monster surged forward. Yuji and Rika met it head-on, clashing with cursed fists and spectral jaws. For a moment, the Null Beast faltered, snarling as Sukuna's power tore into its core.
But then it retaliated.
A beam of burning void split the zone, hurling Luffy across the horizon. Goku barely caught him. "You okay?"
Luffy grinned through broken teeth. "Best vacation ever."
Yuji knelt, panting. Rika flickered.
"We need to end this," Goku said. "Fast."
He floated higher, eyes closed.
"I remember now. What I was. What this thing is."
The beast lunged. Goku raised one hand. Light exploded.
A blade formed in his palm—shaped like a memory, burning with the power of lost gods.
"The Sword of Suns," he whispered.
With a scream, Goku charged. The blade carved through the creature, cutting deeper than energy, deeper than matter—severing memory itself. The Null Beast screamed as its form unraveled, peeling away layers of stolen power.
Luffy wrapped his arms around what remained, yanking it back into the fracture.
Yuji summoned a cursed seal and locked it.
With a final pulse, the Null Beast vanished.
The zone fell still.
"Nice sword," Luffy said, panting.
Goku didn't answer. The sword dissolved in his hand.
"It's not mine," he said. "It belonged to the First Guardian. The one I used to be."
A voice echoed from the void: "You are ready."
A new rift opened—stable, glowing with all five energies.
Home.
They stepped through.
But behind them, something stirred in the cracks.
Watching.
Waiting.
