Overlaying her knowledge of the human anatomy, she analytically understands Sasuke's Chidori punched right through the false ribs eight, nine, and ten, and part of Naruto's stomach. Sakura gravely notes the specks and splatter of red on the floor, thinking, 'that's a lot of blood.'
Distastefully astonished, Kiba mutters what the other genin are thinking, "damn, Sasuke"
"His own teammate," Chji slowly voices in horrid awe, never in a million years thinking a teammate could do that to another.
Though Kurenai hides her rapidly devolving turmoil behind her glazed mask, her heart is beating painfully fast, and at the reverberating sound of Naruto's scream, she's stopped breathing.
Her body overheats, her knees feel paper-thin, and her toned gut tightened to steel as she mentally screams, 'nonononononono!' Despite being a kunoichi who believes in village unity, especially among countrymen, her angry red eyes land on Kakashi, mentally yelling, 'you let this happen!'
After redirecting what would've been a strike to the heart, Naruto's weakened hand desperately grips Sasuke's bloody forearm as he screams till he's out of breath. With a face of unbridled anguish, his sweaty blond head falls forward, locking piercing blue eyes with Sasuke's three-tomoe Sharingan.
Through the salting spikes of pain drills continuously down to his twitching toes, Naruto's blood leaking mouth gasps, "you really"
"It's over," a stern-eyed Sasuke calmly asserts, roughly removing his arm from the bloody hole he created.
He grips Naruto's neck as he comments, "you may have deflected my attack but you can no longer- NGGH!" Sasuke grunts as Naruto's jittery hand grips Sasuke's wrist before doubling then tripling in strength.
Within the dank depth of Naruto's seal, in the dark room of the flooded grand chamber, and before the tower-tall shoddy gates, Naruto grimly stares up at an impressively irate and growling Kurama.
Feeling just as insanely provoked, Naruto extends two fingers to his orange-furry partner and Kurama chuckles. Red chakra then flows forward with purpose, enveloping a very willing Naruto in the seal as it does in the dueling chamber.
Kurenai was contemplating beating an apology out Kakashi when the atmosphere in the room suddenly spiked violently, nearly instantly fluctuating the displaced molecules in the air so hard the entire room forcefully heats with an odd blueish-white glow.
The audience is unprepared, shocked, and confused, however, none more so than Sasuke.
The energy in the room quickly grows dark, poisonous, sinister, and before Sasuke could react, Naruto punches him meters away harder than he's ever been hit before, to the point Sasuke ignores the skin-scrapping pain of his body skidding on the ground tearing at his shirt, as well as hitting the wall, for the terrifying sensation radiating from his face, like his fractured skull and torn facial muscles were melting off.
Through his disorientation, Sasuke unleashes the full power of his cursed seal, turning his pale skin dark-gray, his ebony hair long light-blue, adding a black four-pointed star on the bridge of his nose, and sprouting wings in the shape of a hand.
Naruto throws out a large red arm, causing a shock-wave too large for the small room, shoving everyone back. Sasuke jumps over the angry red hand.
Not expecting another arm to shoot out from the previous extension, Sasuke's meaty wings flap him out of the way, only to be grabbed by the feet by another red hand before Naruto whirls him through the air like a ball at the end of a string and slams his teammate into the stone floor at the other end of the room, fracturing a three-foot radius of stone around Sasuke's battered body.
With an ear-piercing roar, the large room shudders in the unrelenting hot density waves bombarding everyone. Naruto pulls on the red chakra hand, explosively drawing Sasuke to him with all the abundant strength in him.
The gray skin of Sasuke's bleeding face flaps like paper in a tornado before contorting around Naruto's iron fist as he's punched so hard, the last Uchiha rockets through the wood and stone wall to the room beyond.
After hearing a meaty crunch and snap in the same breath as heavy stone falling to the ground, and rolling rubble, the room stills. For many moments, all that can be heard from the stage below is the sizzling of Naruto's chakra heating the air and his low snarl.
For all who remember Naruto's antics, Naruto's grades, Naruto's thoughtless boasting the chakra-covered genin below was such an impossible sight to witness.
It was unthinkable to see the blond Dead Last of their class stand tall and dominant against the rookie of the year, the genius Uchiha Sasuke, yet, to deny it would be to deny reality and descend into delusion.
For most, it was like the game they've all been playing since their Academy day was suddenly outdated and boring, especially when Rock Lee asks his sensei, "Guy-sensei, are your sure Naruto-kun was the Dead Last of their class?"
Naruto huffs in mild amusement when Sasuke's shaky gray hand grips the broken stone wall and he slowly staggers through the hole and over rubble.
He's hemorrhaging from his nose, mouth, swollen left eye, and unswollen right eye, sweating profusely, dirty, and his heavy breathing causes some twitching of his torso, likely from broken ribs.
Naruto wonders if his teammate has a punctured lung but with three slow hand-seals, lighting erupts from Sasuke's left hand along with the sound Chidori is described after.
Naruto sprints faster than an exhausted Sasuke can physically react, cracking the stone floor with his every sprinted step and embeds his body-launching, overpowered fist into Sasuke's gut, instantly snatching Sasuke's left arm to keep the boy from flying away.
Like a running dog chained to a stake, Sasuke grunts loudly as his withheld arm is dislocated by the explosive motion of his catapulted body.
Grunting loudly, the Uchiha grips his dislocated shoulder as his disheveled hair begins to return to its coal-black color, his gray dirty skin to its pale tone, and his single visible Sharingan deactivates.
When Sasuke feebly tries to remove his arm, Naruto doesn't let go, and instead squeezes his forearm that much tighter, drawing a wincing grunt from the last Uchiha.
