Naruto: You Call This A Medical Ninja?

Faced with Reiki's sudden and overwhelming assault, Ōtsutsuki Urashiki was momentarily stunned. But as the pain of Reiki's punch sent him flying, a wild thought emerged in his mind.

This is my chance!

Urashiki's mind raced. If he could kill Reiki here and uncover his secrets, he could surpass all the Ōtsutsuki, becoming the supreme god of Takamagahara.

Fueled by this ambition, Urashiki charged forward, ready to fight.

Boom!

Before he could act, Reiki's fist landed squarely on his chest again, sending him crashing into the ground with bone-crushing force.

The ninjas surrounding them seized the opportunity. Wave after wave of attacks poured down on Urashiki—ninjutsu, taijutsu, and even chakra weapons battered him relentlessly.

Despite his attempts to escape using his space-time abilities, Ōtsutsuki Kaguya ensured his entrapment by manipulating the surrounding dimensions. With no avenue for retreat, Urashiki was forced to endure an unrelenting onslaught.

For six days, the attacks never ceased.

Every time he attempted a counterattack, Reiki or one of the ninjas would thwart him. Even the occasional mistake by the ninjas allowed no real reprieve; the group would recover quickly, thanks to Reiki's presence, and continue their relentless assault.

By the sixth day, Urashiki's famed Ōtsutsuki resilience was the only thing keeping him alive. His body, battered and broken, hung on the verge of collapse.

"The Ōtsutsuki are tough," someone remarked, marveling at his survival.

"Unbelievable," Orochimaru added, licking his lips. "I'd love to study him..."

Tsunade shook her head with a smirk. "No need to waste more energy. Reiki will finish this."

Reiki finally approached the battered and broken Ōtsutsuki Urashiki, who lay on the ground, breathing heavily. Naruto and Sasuke stood silently behind him, watching the scene unfold.

Urashiki, seeing Reiki approach, mustered what little strength he had left.

"You might be strong now, Reiki," Urashiki sneered weakly, "but the Ōtsutsuki clan will never stop hunting you. If not me, then another. One day, we'll erase you before you even realize it."

Reiki looked at him calmly. "I'm not here to kill you. Let's make a deal instead."

Urashiki blinked, caught off guard. "A... deal?"

"Yes," Reiki said, summoning a long blade that emanated a deadly aura. "Of course, if you'd prefer to die here, I'm happy to oblige."

Seeing the sword, Urashiki's arrogant facade cracked. "What kind of deal?"

Reiki crouched down, looking directly into Urashiki's panicked eyes.

"Leave your contract in the ninja world," Reiki said. "From this moment on, you'll become part of this world. No more destruction, no more invasions. Just live here peacefully for eternity."

Urashiki's eyes widened in disbelief. "You want me to... surrender my freedom?"

"It's your choice," Reiki replied nonchalantly. "Accept the contract or die. Either way works for me."

Urashiki hesitated. "Why do they—" He pointed weakly toward Kaguya and Tate—"get to stay freely?"

Reiki's gaze turned icy. "They earned my trust. When you prove you're no threat to this world, you'll regain your freedom too."

Urashiki scoffed weakly, but inside, his mind churned. He hated the idea of submitting, but the alternative was death.

"I refuse!" he finally spat. "If that's your deal, then just kill me!"

"Alright." Reiki didn't hesitate.

Before Urashiki could retract his words, Reiki swung his blade, slicing through the Ōtsutsuki's body in one clean motion.

"Wait—no!" Urashiki shouted, panic flooding his voice.

"It's too late," Reiki said coldly. "Even if you agreed, I planned to destroy your body. You don't deserve it."

With another swing of his blade, Reiki severed the connection between Urashiki's body and his chakra, leaving his essence adrift.

"Shisui!" Reiki called out.

Uchiha Shisui appeared at his side instantly. "Yes?"

"I need your help," Reiki said, pointing toward Urashiki's chakra essence. "If you're willing, I want you to become his Jinchūriki."

Shisui's eyes widened. "What?!"

Reiki nodded. "It's the best way to ensure he's contained and can't harm the ninja world."

After a brief hesitation, Shisui extended his hand. "If you trust me to do this, I'll do it."

Reiki's eyes glowed with the power of his Pure Eye, a technique capable of erasing even the most powerful Ōtsutsuki entities.

"Urashiki," Reiki said, his tone devoid of emotion. "This is your final chance. Enter Shisui's body willingly, or I'll erase your existence entirely."

Urashiki hesitated, his essence trembling. He could feel the overwhelming power of the Pure Eye—a force capable of obliterating him.

Faced with annihilation, Urashiki reluctantly complied, merging into Shisui's body.

The process complete, Shisui exhaled slowly. "It's done."

"Good," Reiki said, the glow of his Pure Eye fading. "Keep him in check. If he causes any trouble, I'll deal with him myself."

Shisui nodded, his faith in Reiki unwavering.

As the dust settled, the ninjas around them let out a collective sigh of relief. The nightmare of Urashiki was finally over—at least for now.
