Goku stepped forward in his black gi, the torn fabric hanging loose over his scarred, muscular frame. No smile. No friendly chatter. His eyes were cold, sharp like a predator that had grown tired of playing games. He cracked his neck once, slow, and scanned the streets of Shibuya. Power hummed in the air here. Twisted, cursed energy mixed with something he could use.
Zeno floated beside him, still giggling like none of it mattered. "This place is noisy! Lots of little fighters. You gonna play, Goku?"
Goku didn't answer. He just moved.
The giant spider curse charged again, bigger this time after feeding on the panic. Goku blurred. One punch ripped straight through its face. Black smoke exploded outward, but before it could fade, Goku grabbed a chunk of its core with his bare hand. He squeezed. Dark energy flowed into his palm, thick and bitter, mixing with his own ki. His muscles swelled slightly. The ache from the space battle faded a little more.
Gojo appeared in front of him instantly, Infinity up. "Hold on. You're not from around here. That power... it's not cursed energy. Who are you really?"
Goku stared at him. No words. He threw a simple punch. The air screamed. Gojo's Infinity stopped it for half a second before the force cracked through, sending the strongest sorcerer sliding back twenty meters, shoes carving grooves in the concrete.
Gojo's grin widened, but his eyes were serious now. "Okay. You're strong. Real strong."
More curses poured out from the shadows, drawn by the chaos. Yuji, Megumi, and Nobara arrived, breathing hard. Yuji stepped up first. "Gojo-sensei, we got this!"
Goku ignored the kids. They were too small, too weak. Wasting time. He flashed past them like a black shadow. His fist slammed into a curse the size of a building, bursting it apart. He absorbed its energy again, pulling the cursed power straight into his body. It tasted nasty, but it fed him. Every kill made the Omni God spark inside him burn hotter.
A special grade curse with long bladed arms tried to slash him from behind. Goku caught the blades with one hand. He twisted. The curse screamed as its limbs snapped. Goku drove his fingers into its chest, ripped out the core, and crushed it. More energy rushed into him. His black gi fluttered as his power rose.
Gojo teleported in close, trying Unlimited Void. The domain opened. For a moment, infinite information flooded toward Goku.
But Goku just powered up. White-gold aura exploded outward, shattering the domain like cheap glass. He grabbed Gojo by the collar with one hand and slammed him into the ground hard enough to crater the street. Gojo coughed blood but still smiled.
"You... don't talk much, huh?"
Goku said nothing. He lifted Gojo again, studying him. This one had real power. Worth taking. He punched Gojo in the gut, deep and brutal. As the sorcerer doubled over, Goku placed a palm on his chest and started pulling. Streams of blue cursed energy mixed with raw strength flowed into Goku's body. Gojo's eyes widened in pain and surprise.
"Not... bad," Gojo rasped.
Before Goku could finish draining him, Mahoraga appeared from Megumi's shadow, summoned in desperation. The giant shikigami swung its sword. Goku turned and met it head-on. The clash sent shockwaves through Shibuya. Buildings swayed. Glass rained down.
He fought in silence. Every move was efficient, deadly. A kick broke Mahoraga's arm. A elbow drop cracked its head. When the shikigami adapted, Goku simply powered up higher, his hair flashing between black and that new white-gold. He grabbed Mahoraga by the neck and slammed it into the ground over and over until the divine general exploded into dust. Goku absorbed what he could from it too. The energy felt cleaner, stronger.
Zeno clapped. "Yay! Stronger again!"
Yuji ran in, Sukuna's markings spreading across his face. "You bastard! Leave Gojo-sensei alone!" He threw a Black Flash.
Goku blocked it with his forearm. The impact pushed him back only a step. He looked at Yuji with flat eyes. The kid was angry, but young. Goku backhanded him lightly—enough to send Yuji crashing through a storefront. Not dead, but out cold. He didn't kill the weak ones unless they annoyed him too much.
Nobara and Megumi tried to jump in. Goku ignored them completely. They weren't worth the effort.
A group of curse users and higher-grade sorcerers arrived, drawn by the destruction. One woman among them, tall with sharp eyes and long dark hair, stared at Goku with a mix of fear and something else. Her cursed energy was thick, seductive in its own way. She had been fighting alongside the others but now stepped closer, curious.
Goku felt it. The heat in his body after all the fighting. The need. He blurred to her in an instant. Before she could react, he had her pinned against a half-broken wall, one strong hand around her waist. No words. He kissed her hard, rough, the kind that left bruises. She gasped but didn't push him away immediately—part shock, part the raw power rolling off him. His free hand roamed, tearing at clothes. Right there in the ruined street, with dust still falling, he took her. Hard and fast. Her moans mixed with the distant screams of the city. Energy flowed both ways. Her strength poured into him while he used her body. When he finished, he dropped her gently enough. She slid down the wall, breathing heavy, eyes glassy with pleasure and confusion.
Goku wiped his mouth and turned away. Refreshed. Stronger.
Gojo had gotten back up, wiping blood from his lips. "You really are something else. Not good, not evil... just pure want."
Goku finally spoke, voice low and rough. "Strong ones. Bring them."
He powered up fully. The black gi strained against his body as the white-gold aura erupted. The ground around him shattered. Cars flipped. Every curse left in Shibuya felt it and either fled or charged straight at him like moths to fire.
Goku moved through them like death. Punch after punch. No flashy moves, just brutal efficiency. He killed dozens, absorbing their cursed energy each time. His power kept climbing. A curse user tried to bargain. Goku broke his neck and took his energy too.
Zeno watched from above, swinging his legs. "This is getting fun! But don't break the whole planet yet, Goku!"
Sirens wailed. Helicopters hovered in the distance. More jujutsu sorcerers were coming—stronger ones. Goku stood in the middle of the destruction, breathing steady, black hair wild, eyes glowing faintly. He could feel bigger prey approaching. His body ached for more fights, more power, more release.
He cracked his knuckles once and waited.
The night in Shibuya had only just started burning.
