Naruto: You Call This A Medical Ninja?

After leaving that world, Reiki returned to Konoha. Using his unique system, he scanned the entire village thoroughly. Confirming that no anomaly like Koizumi existed, Reiki breathed a sigh of relief.

After locating Kurenai and Shizune, he took them directly out of Konoha, heading toward the special training camp. Reiki needed to investigate something, making it inconvenient to bring others along for the journey.

Once they reached the camp, Reiki provided Kurenai and Shizune with ample training resources and then set off to find Tsunade.

Tsunade's Residence

Upon arriving at Tsunade's residence, Reiki was greeted by a scene that warmed his heart.

"Teacher."

"Master Jiraiya."

"Master Orochimaru."

The Legendary Sannin of Konoha were enjoying food and drinks together. It was a rare and cherished sight, one that brought a smile to Reiki's face. At least for now, the trio no longer seemed divided or burdened by their past.

His teacher's brilliant smile was something Reiki deeply cherished and wanted to protect.

"Reiki?" Tsunade noticed him and immediately called out. "You came at the perfect time. We're discussing the next phase of training."

"The fourth simulated invasion is scheduled for a year from now," she continued. "So, I think we can adjust our training approach this year. Look…"

Tsunade enthusiastically explained her idea, which involved shifting from individual combat training to combination training. The focus would be on teamwork, emphasizing task-oriented drills to simulate real mission conditions.

Reiki nodded in agreement. "That's a great suggestion, teacher. It will definitely enhance collaboration."

"By the way," Reiki added, "I'm here to inform you that I'll be leaving the special training camp for a while. I need to search for something."

Concerns and Plans

Tsunade's expression shifted to concern. "Leave? Where are you going? Did you encounter a problem?"

Reiki smiled reassuringly. "I encountered someone unusual today and obtained some special information. I need to follow up on it, but don't worry—there's no danger."

"Well," Tsunade said after a pause, "at least stay and share a meal with us before you leave."

Reiki obliged. After sharing a hearty meal with his teacher and the other Sannin, he stepped out of the residence and made his way to the training grounds.

Gathering the Team

Waiting for him outside were Hanyu Asawa, Uchiha Shisui, Namikaze Nozuki, and several others, including members of the orphanage and Kakashi.

"Boss," Asawa began, "what's going on? Are you planning something big? Take us with you if it's a mission!"

Reiki had anticipated their eagerness. While visiting Tsunade, he had sent his shadow clone to summon everyone.

"This time, I've encountered a formidable opponent," Reiki explained. He turned to Kakashi. "Have you mastered the art of summoning yet?"

"Yes," Kakashi confirmed, immediately forming seals. Placing his hand on the ground, he summoned his ninja dog—a small, adorable pug.

"Good," Reiki said. "Everyone who has mastered summoning, stand to the left. Those who haven't, stand to the right."

To Reiki's surprise, Obito hadn't mastered summoning yet, even though Nohara Rin already had her own summon.

The Plan

Reiki assessed the lineup of summoners:

Hatake Kakashi [Ninja Dog] Uchiha Shisui [Ryuchi Cave] Namikaze Nozuki [Shikkotsu Forest] Might Guy [Kelingang]

Satisfied, he turned to the group. "I need your help with something critical," Reiki began. "First, I need the summoning seals of your contracts. Second, those who haven't mastered summoning will undergo specialized training. Do you trust me?"

The group responded without hesitation, their confidence in Reiki unwavering.

"Boss, you don't even need to ask!"

"Whatever you need, we're here for you!"

Shisui added, "If you're planning to visit the Sage Lands of our summons, I can take you directly to Ryuchi Cave without requiring a reverse summoning."

Reiki nodded, gratitude evident in his expression. "Thank you all."

Departure

Reiki started by summoning Mochizuki, his immense summon whose presence alone radiated overwhelming power.

"Mochizuki," Reiki said, "take them to the Sage Lands for their training."

Mochizuki tilted her head in curiosity but quickly understood. "Understood," she replied, her massive tail sweeping up the group before they disappeared.

Turning to Might Guy, Reiki said, "Let's start with you." Taking out a blank scroll, Reiki recorded Guy's summoning technique and prepared for reverse summoning.

"Reverse Summoning!" Reiki channeled his chakra into the scroll. As spatial fluctuations surrounded him, his body dissolved into white mist, vanishing from the spot.

His journey to uncover answers had begun.
