A year ago, Dosuke found his chakra was too low when he first arrived in this world. He could not rely on ninjutsu, so he decided to focus on taijutsu. He knew Might Guy's kicks were powerful enough to nearly end the story in the future.
Dosuke acted quickly. That night, he sneaked to the Konoha Forest. He stayed near the training ground by the Forest of Death, avoiding deeper areas. His small house was fine for chakra training, but taijutsu needed more space.
At the training ground, someone was already there. A figure kicked sandbags tied to trees.
"One thousand one hundred twenty-seven."
"One thousand one hundred twenty-eight."
"One thousand one hundred twenty-nine."
"One thousand one hundred thirty."
Tap. Tap.
Dosuke stepped from the shadows and raised his hand to greet.
The figure spun around.
"Leaf Whirlwind!"
Bam.
Dosuke flew backward, faster than he had come.
Crash. He hit a tree.
He groaned.
Under the moonlight, Dosuke spat blood. It stained his short-sleeved shirt red. A large footprint marked his light blue top.
Might Guy ran over and saw his classmate. "Dosuke, it is you! Are you okay? Can you stand?"
"Do I look okay?" Dosuke spat more blood before finishing.
"Why are you staring? Get me to Konoha Hospital!" Dosuke glared at Guy, who seemed stunned by his mistake.
"Oh, oh!" Guy moved to lift Dosuke.
"Wait! Carry me on your back. You probably broke my ribs. Do not hug me," Dosuke snapped.
"Okay, okay, Dosuke-kun. I will be careful," Guy replied.
Guy slid one arm around Dosuke's waist and the other under his legs, lifting him in a princess carry. Even with Dosuke's weight, Guy moved fast, used to running around Konoha for exercise.
At the hospital, a medical ninja in a white uniform checked Dosuke. "You came early. Only two ribs are broken, and no organs are damaged. You still need surgery. Call your family to settle the medical fees."
"Wait. Treat Dosuke-kun first. I kicked him, so I will take responsibility. I will get my father now," Guy said, panicked.
"No need. I am alone. My parents died in the Second War. I am a martyr's child. Lord Third's policy says I get free treatment. My father's ninja number is 754264945. Please check," Dosuke told the medical ninja.
"Wait a moment. I will verify your information." The medical ninja wrote in a register and left.
"Dosuke, I am sorry. If you die, I will die too," Guy said, kneeling by Dosuke's bed, tears falling.
"Can you wish me well? I will not die," Dosuke said weakly, eyes closed. He tried to pull Guy up but could not move.
"Where is the patient?" a strong female voice called.
"Here, Tsunade-sama," the medical ninja replied.
Creak. The door opened. The medical ninja stepped aside, letting a woman enter.
Tsunade walked in, her blue top tight, blonde hair in twin ponytails.
"Tsunade-sama!" Guy shouted.
"You kicked your classmate like this, kid?" Tsunade glanced at Dosuke, who lay with closed eyes.
"Yes, it is my fault," Guy said, head down, hands behind his back.
"You, gather the medical ninja still in the hospital. His treatment is free, so I will demonstrate," Tsunade told the medical ninja who brought her.
"But, Tsunade-sama—"
"Just go! What is wrong with free treatment?"
Dosuke sweated on the bed, * Is it pain or nerves? * , he thought.
Soon, the room filled with medical ninja.
"Watch. There are no external wounds. First, sense the broken ribs with chakra. Then move them back to the fracture," Tsunade said, using the Mystical Palm Technique. "Next, speed up bone regeneration with the same technique."
"Pay attention. The Mystical Palm Technique must be precise. If your chakra is not pure, you cannot stimulate bone growth correctly, and the bones will misalign."
"Done. Move him to rehabilitation and observe him for a few days," Tsunade said.
She was truly a Sannin, famed from the Second War and praised by Hanzo of the Salamander.
"Thank you, Tsunade-sama," Dosuke said weakly.
Tsunade waved and left the ward.
After treatment, Dosuke spoke to Guy. "Be careful next time. Tsunade-sama healed my injuries, but hidden damage from intense training cannot be fixed."
"I understand, Dosuke. My body is strong, and my youth burns hot!" Guy posed, left hand on his hip, right hand forward, teeth glinting.
"Enough for today. The school's ranking battle is in a week. I may not come here for a few days. Practice safer moves," Dosuke said, patting Guy's shoulder with a strange look.
"I know. I will beat Kakashi in the ranking battle. It makes my blood boil!" Guy's eyes sparked.
"Fine. Let us go," Dosuke said, turning to leave.
"Dosuke, wear a green training suit! It works!" Guy shouted after him.
Dosuke stumbled, waved without looking back, and leaped onto a tree branch, heading home.
At the Okamoto house, Dosuke lay in bed. * The school's ranking battle is soon. Kakashi is five. In the story, he graduates after this, becoming Konoha's youngest genin, then chunin, and a jonin at twelve * , he thought.
* This ninja world values lives so little. My chakra is too low for long fights. I need to reach chunin to protect myself. In the ranking battle, I must show my skills to catch the leaders' eyes, maybe even become a disciple * , he thought.
* Kakashi's graduation means the Third War is near. I have little time. I must survive and make my name in this world * , Dosuke thought, clenching his fists under the blanket.
