Ryu hovered in the air and smirked "Hold on, old man. Don't die, alright?" Madara snorted, "Show me what you got, little one." Ryu bubbled with laughter and his devil's grin resurfaced as he said "I've always wanted to say this!"
(Author's authority Stereo Saiyan is playing as BGM in universe! You can't complain! I only get one chance to use this!)
He clenched his fists and made a horse stance in mid air, shouting "This is Flame Sage mode!" he flashed and his Susanoo appeared around his body tightly like armor, "And this is Flame Sage Mode and Susanoo armor, or you can just call this Flaming Sage Armor!"
Madara snorted, "Get on with it, boy!" Ryu smirked "Heh. Just wait!" Minato played the role, gasping "Has he surpassed Sage mode?!" Guy was also here, adding "That's impossible!"
Ryu flexed and shouted "And this! IS TO GO EVEN FURTHER BEYOND!" his body lit up and his eyes exploded with light as he roared at the sky and smashed out his limbs!
The air vibrated and the world shook!
Guy said in shock "What is this?!" Minato shouted "Oh no! The whole world is shaking!"
All the flames were snuffed out and black smoke wafted from Ryu's body as his armor split on his face, revealing his eyes!
The shaking stabilized and Ryu stood there with an emotionless gaze, black smoke wafting from the corners of his eyes as his hair swayed behind him without any wind. His arms were wrapped in black wispy smoke as he snorted with a word.
Madara narrowed his eyes and said "Rinnegan ability? Interesting." Ryu looked at him without words, flashing and appearing in front of Madara in an instant!
Madara's eyes widened, "So fast?!" as he blasted into the sky!
Ryu stood in the same spot, turning his head up at the sky before crouching down and saying softly "Come on, old man…"
He jumped off the ground and it shattered into countless pieces, leaving a super massive crater under him!
Madara turned in the air and condensed all his Truth Seeking Balls onto his arms, covering them with haki, condensing pure blue Susanoo armor on his body as he punched down with every ounce of power!
Ryu and Madara collided but there was no sound!
Nothing!
Everyone looked up in shock as an incredibly loud sound buzzed across the world!
A massive burst of air blasted everything around the duo!
Ninjas were thrown several miles away from the impact, getting swept off their feet but not injured!
Black cracks started appearing around Madara and Ryu as the air itself was shattering from their power!
Ryu roared and blasted Madara flying, blowing away half his body! Madara flew through the air and smashed into the God Tree!
Madara shattered the tree around him and laughed "Good boy! In all these years, I, Madara, want to call you the strongest! Hahahaha! Dance more with me, Ryu!" his body reformed in an instant as the white bone on his forehead collapsed!
He blasted the tree behind him and shot into the air, launching himself at Ryu!
He flipped in the air and smashed his foot on Ryu's head!
Ryu blocked with his arms and sank in the air, snorting as Madara shouted "Come on, Ryu! Don't disappoint me!" Ryu looked up at Madara and grinned like a devil as his eyes turned crazy!
"Let's dance, old man."
Ryu swung his arms and blasted Madara into the sky as he blasted after him, kicking Madara in the side, sending him smashing through the God Tree like a shooting star, cleaving a canyon into the Earth for miles!
He flashed after him and dropped his leg on top of Madara at the end of the Canyon!
There was a huge BOOM and a massive pillar of Magma erupted from the ground, shooting out from the core of the Earth!
Madara emerged from the magma and laughed, throwing a fist at Ryu, punching him right in the face, blowing out a bowl shaped crater! He shot after him and clenched a fist, saying "Annihilation!" before throwing it down as a black air surrounded it!
A massive pillar of black energy blasted Ryu in the hole, smashing him deep into the Earth, submerging him in lava!
Ryu shot out of the ground and flickered behind Madara, kicking him in the head!
But!
Madara blocked with his arm and swung around, smashing the back of his hand on Ryu's face before grabbing his leg and smashing him into the ground, leaving the Earth to tremble!
Ryu pushed off the ground and stomped on Madara's face, locking his feet around his neck and flipping him over, smashing him face first into the ground before grabbing his legs and flipping him over, using Madara like a hammer!
He grabbed Madara's head and smashed him into the ground before running towards the God Tree, dragging Madara all the way! He exploded off the ground and smashed through the God Tree, Madara first!
They emerged from the other side and Ryu flipped Madara over, grabbing his arms and stomping on his back, riding him like a sled into the ground!
There were sparkles around the impact and the collision seemed to lag before exploding with square shaped rubble, sending them to the sky before evaporating into nothingness!
Madara flipped up and grabbed Ryu, throwing him into the air before flashing and kneeing him in the back, sending him higher and higher, kicking all the way before flickering above him and smashing down with both fists!
He shot after him, kicking on the air and flipping through the air, gaining momentum before stomping on Ryu's stomach with both feet, drilling him through the ground!
Madara burst into crazy laughter as he was completely covered in blood, slowly regenerating as he was almost completely naked, not even bothering to use any jutsu or Truth Seeking balls except for gauntlets and leg bracers!
Ryu jumped off the ground and dragged Madara through the Earth, flying into the air as they clashed over and over again, blasting out shocks of air, sending Ninja everywhere flying as the rest of the people on the planet could feel the incredible power!
Ryu and Madara collided fists and smashed their foreheads, blocking with their knees as they kicked each other, all their movements blurry to the naked eye!
Ryu flicked his hand and grabbed Madara's wrist, spinning around before slamming Madara into the air and punching through his chest!
Madara coughed up blood and grinned "Yes! This is the excitement! HAHAHAH!" as he grabbed Ryu's arm, smashing his elbow on it, snapping it! Ryu's face twitched in pain as Madara flipped over with Ryu's arm in his chest, kicking Ryu in the mouth, shattering his armor once again, sending him to the ground.
Ryu groaned and flicked his arm, snapping his bones back into place. Madara bubbled with laughter and looked at Ryu with excitement "Good!" as he dropped from the sky like a Meteorite!
Ryu clenched his fist and looked up at Madara, squatting down before shooting off the ground as a blazing black flame burst on his arm, smashing at Madara! Madara's eyes lit up and he clenched his fist, covering it with all his power, a black haze surrounding his black gauntlet covered fist as the other Truth-Seeking Balls merged into the gauntlet, condensing it into a black pattern on his fist!
His arm exploded with black haze as the two fists collided!
In between the fists was a bit of air that was ripped apart, becoming a black void! Madara and Ryu's susanoo armors shattered piece by piece as they roared!
Ryu's arm surged with black flames and Madara grunted with a crazed grin before getting overwhelmed and blasted out of the sky!
Ryu's Super Sage Mode Final Flash Susanoo Form faded and he fell from the sky, landing on the ground without any movement.
Madara closed his eyes and smiled as blood escaped from his lips, landing right next to Ryu.
Noticeably, only Madara's left arm, heart, and left half of his face remained!
Ryu wasn't doing much better as his right arm was gone from the shoulder!
Naruto and Sasuke flashed over with Minato and looked at the duo, unable to speak any words at all!
Minato finally came to his senses and said "Amazing… It's incredible!" Naruto pressed on Ryu's chest and let out a breath of relief, saying "Okay… He's okay!" Sasuke squatted down and took out a small bag.
He poured out 2 Senzu Beans, putting one in Ryu's mouth and holding the other one.
Ryu slowly groaned and opened his eyes, saying "Ah… The Pure Land?" Sasuke looked at him quietly before saying softly "Not yet, old man." Ryu coughed up some blood and smiled "Hey, kid." Sasuke burst into tears and held the other Senzu Bean at his mouth, but Ryu said "Feed… Ma-Madara… Damn…"
Naruto said "But, Ryu!" Ryu coughed and grabbed at Madara's left arm, "G-Grandpa… Wake u-up… Bastard…" Sasuke's face changed slightly and he fed the Senzu Bean to Madara, who groaned as his regeneration increased instantly, recreating his missing parts!
It was a miracle he was alive at all!
Ryu's own arm grew back as well and he sighed at the magic of Senzu beans… Give a few to Kaguya and maybe she really ruled the world?
Madara opened his eyes and said "Ah… The Pure Land?" Ryu chuckled, "What a retard…"
Naruto, Sasuke, and Minato shut their mouths, thinking 'You… didn't you just say that exact same thing?'
