Whoosh.
Kakashi formed a one-handed seal. He used the Body Flicker Technique.
He appeared before Dosuke in a flash. His dagger, glowing with chakra, slashed at Dosuke.
Dosuke leaped backward, barely dodging. His movements were quick but unsteady.
"Wind Style: Gale Palm!" Kakashi changed his attack. A sharp gust of wind chakra shot forward.
Dosuke ducked sideways, landing clumsily on the ground.
Dosuke pointed his right index finger at Kakashi's back.
"Water Style: Water Bullet!" A small, palm-sized water bullet fired at Kakashi.
Puff.
It hit a wooden log on the ground.
Kakashi had used the Body Flicker Technique and Substitution Technique.
"How do you move so fast?" Kakashi asked, his eyes narrowed, watching Dosuke struggle to stand. Dosuke's movements were strange, like he was pushed by water. * If I keep attacking, he'll run out of chakra soon * Kakashi thought.
Daisuke, the Hyuga clan leader, watched from the sidelines.
He spoke. "The kid in the orange jacket leaves a blue footprint when he lands. It's a tiny water trap under his feet. It bursts with force, pushing him along. He controls it with chakra."
"His control is good for his age. Even the Hyuga can only control chakra inside our bodies. This outside control is rare," Daisuke said.
"If he were born a Hyuga, he could rival Lord Tobirama when grown," Shoma, a branch Hyuga, said.
"Could his kids learn that control if he joined our clan?" Yuta, a Nara jonin, asked, rubbing his beard.
"Watch the fight," Hiruzen said.
Dosuke faced Kakashi, his face tired. * I need to end this fast. My chakra's almost gone * he thought.
"Lightning Style: Thunderbolt!"
A blue lightning bolt zipped toward Dosuke.
Whoosh.
Dosuke jumped aside, but his leg shook. He barely avoided the bolt.
"Water Style: Water Bullet!" Dosuke shot another water bullet.
* He's slowing down. I can win this * Kakashi thought.
"Wind Style: Great Breakthrough!"
A gust of wind blasted forward, knocking Dosuke's water bullet away.
Dosuke tried to move, but his water trap sputtered. He stumbled, panting heavily.
Kakashi dashed forward, kunai in hand.
"Water Style: Water Wall!" Dosuke raised a shaky water barrier from the ground.
Kakashi's kunai sliced through the weak wall, grazing Dosuke's left arm. A little blood dripped.
Puff.
Kakashi vanished in smoke, using the Substitution Technique.
"Earth Style: Double Suicide Decapitation Technique!"
Hands reached from the dirt beneath Dosuke, grabbing his ankle.
Whoosh.
Dosuke broke free with a weak water burst, but he was gasping now. His movements were sluggish.
"Dosuke, give up. Your chakra's low," Kakashi said, standing tall.
"No way. I can still fight," Dosuke said, his voice faint.
"They're both talented for ninja school students," Daisuke said from the sidelines.
"Konoha's future is bright," Hiruzen said, watching closely.
"Kakashi, take this!" Dosuke shouted, using his last chakra.
"Bring it, Dosuke!" Kakashi said, his eyes sharp.
Dosuke charged, a thin water blade forming on his palm. It was his own technique, Water Fang, made for close combat.
Kakashi spun, lightning crackling in his right hand. He hadn't perfected this move yet.
* His footprints show the real Dosuke. I just need one hit * Kakashi thought.
Dosuke's Water Fang slashed at Kakashi, but it was slow. Kakashi dodged easily.
"One chance, Dosuke!" Kakashi's hand sparked with lightning, chirping loudly.
Dosuke tried to block with a water layer on his hand, but it was too weak.
"Kakashi, here I come!"
Bam.
Smoke cleared. A man with a Konoha headband, ninja vest, silver-white hair, and a ponytail stood between them. He grabbed Dosuke's right hand with his right hand and Kakashi's with his left.
Dosuke's water jutsu and Kakashi's lightning jutsu fizzled out.
Boom.
Dosuke's Water Fang hit the ninja school's wall, cracking it slightly.
"Father!" Kakashi said, seeing the man.
"You both fought well," Sakumo said, glancing at the wall. "I wasn't this strong at your age."
He let go of their hands.
Thud.
Kakashi sat down, breathing hard. His hand stung from the unfinished lightning jutsu.
Dosuke's right hand hung limp, burned by Kakashi's lightning. Blood trickled from his left arm.
"They're strong, but not as great as me," Obito said, adjusting his orange goggles.
"Kakashi, you hurt Dosuke! You're my rival forever!" Guy shouted, gripping the railing.
Whoosh. Whoosh.
Tsunade and Jiraiya appeared.
"Kid, your arm's bleeding," Jiraiya said, looking at Dosuke.
"I'm fine, Jiraiya-sama. I can heal it," Dosuke said. He used the last of his chakra for the Mystical Palm Technique. The wound on his arm closed slowly.
"Jiraiya-sama, it's healing. I…" Dosuke fainted in Jiraiya's arms.
"Tsunade, he's out!" Jiraiya said.
"He overused his chakra. Kakashi's just tired, with a sore hand from his jutsu. They'll be fine. Take them to the hospital," Tsunade said, checking them.
She picked up Dosuke and carried him toward Konoha Hospital.
Sakumo followed, carrying Kakashi on his back.
