Naruto: You Call This A Medical Ninja?

Although Onoki and Rasa arrived at the negotiation site two days early, delays from the other villages caused the meeting to be postponed.

By this time, Tsunade and Reiki, having left the battlefield, were en route to the Land of Rivers.

Preparations in the Land of Rivers

"Sensei, I'll head to the local Chamber of Commerce to restock medicinal supplies first," Reiki said. "You can take a break or head to the casino nearby if you like."

Tsunade raised an eyebrow but didn't think twice. Knowing Reiki's meticulous nature, it made sense for him to prepare for future battles. As for her, a casino nearby offered the perfect opportunity to unwind after the grueling conflict. Without hesitation, she made her way to the casino.

Reiki, however, had a different objective. After entering the medicinal shop, he activated a barrier, ensuring privacy.

"Black Zetsu, you called for me?" Reiki said flatly.

Before him stood a man with dull eyes, slowly overtaken by creeping black tendrils. Black Zetsu revealed himself fully.

"I want to discuss our cooperation," Black Zetsu began cautiously.

"Cooperation?" Reiki chuckled, his tone sharp. "What exactly do you think we have to talk about? I don't need your help for anything. It's you who should state your intentions."

Realizing his precarious position, Black Zetsu didn't hesitate. "My goal is to rescue my sealed mother, Otsutsuki Kaguya!"

Black Zetsu went on to reveal his plans and the history surrounding Kaguya, sparing no detail. While the information sounded fantastical, Reiki listened carefully, piecing together the fragments of truth.

"So, you're telling me that breaking the Yin-Yang seal is the only way to release her?" Reiki asked.

Black Zetsu nodded earnestly.

"Interesting. But what about the origin of White Zetsu?" Reiki pressed.

Caught off guard, Black Zetsu hesitated. "White Zetsu... they were created by my mother, but the specifics are unclear, even to me."

Reiki leaned back, his gaze piercing. "Your mother created them for a reason. Let's figure that out together. You're coming with me to the Five Kage Summit. There, we'll exchange information."

Reiki handed Black Zetsu a scroll filled with ancient knowledge about the Otsutsuki clan, material he had acquired through dimensional means. The archaic nature of the document added to its credibility.

Black Zetsu's expression shifted as he read. "You're saying that releasing Kaguya will expose the ninja world's coordinates to the Otsutsuki clan? And that the clan will come for us afterward?"

Reiki nodded. "If the ninja world isn't prepared, it will face annihilation. Decide wisely."

After a moment of silence, Black Zetsu attached himself to Reiki's hand and left.

A Familiar Casino Scene

Inside the casino, Tsunade was in her element.

"29 again? Too big!" she exclaimed, slamming her money down.

Reiki approached, placing his own wager beside hers. "I'll go with you on this one, Sensei."

Tsunade grinned. "See? With you around, I might actually win this time!"

The dice cup was revealed: "One, one, two, four points!"

"Yes! We won!" Tsunade cheered, grabbing her winnings. "Reiki, you're my lucky charm. Let's go!"

With their winnings in tow, the two left the casino, Tsunade visibly refreshed and ready for the summit.

The Five Kage Arrive

At the neutral site in the Land of Fire, an unassuming wooden house served as the meeting place. Mizukage Yagura and his guards arrived, greeted by the stern presence of the Third Raikage and his team.

"You're here, Mizukage," Raikage said gruffly. "Finally. Took you long enough."

Yagura responded diplomatically, but Raikage brushed off further pleasantries, storming into the meeting room.

The Raikage's irritation was palpable. His earlier preparations to counter Konoha had been rendered meaningless. Not only had Sunagakure fallen, but even Iwagakure's intervention had ended in humiliation. Seeing Onoki and Rasa subdued by Madara had shaken him.

Yagura, still piecing together the situation, followed the Raikage inside.

The Start of the Summit

The Kage and their guards settled into the room, tensions high.

"Mizukage-sama, you look unwell. May I treat you?" Reiki offered as Yagura entered, stepping forward with a professional demeanor.

Yagura hesitated, startled by the unexpected gesture. But before he could reply, Reiki's calm presence diffused the moment.

As the Kage exchanged wary glances, the Five Kage Summit began, and the true stakes of the ninja world's future came into focus.
