Unseal

"Us?" Yamanaka Ryo captured the message in Rikudō Sennin's words. This 'us' shows that not only Rikudou Sennin alone observed what happened in Ninja World, other people also did the same thing. With this in his thought, Yamanaka Ryo's expression became more serious. Rikudou Sennin had no idea that a piece of information accidentally spoken raised Ryo's vigilance. But he thought he was acting that way because of Kaguya.

After a while, Rikudou Sennin urged Ryo, "Indra's descendant, tell me what you're thinking."

"Oh, my bad. I was just thinking about something else. My plan is this…"

Listening to Ryo's plan, the battle-hardened Rikudou Sennin was startled. It took some time to regain his sense back. "Indra's descendant, I have to say your ideas are bold and crazy."

Ryo smiled, "But this way, we can solve the hidden dangers hiding in the Ninja World from its roots."

Rikudou Sennin nodded, "That's right. But I don't think it's very effective. With your own strength, you can't do it. Not just you, even my mother can't."

"So, that means you won't give me your Chakra?"

"Un… Your plan is too bold. I can't believe you just yet. Rather than you, I'd prefer to believe Indra and Asura's reincarnation.

"Of course, it's because they're your own children. They're even more reliable than me, whose bloodline had descended for dozens of generations later."

Rikudou Sennin laughed and didn't argue back. Yamanaka Ryo continued to say, "I understand what you're thinking. It's only natural. But still, I have to say you're making a wrong decision today. The next time we meet, you'll see what I'm talking about."

"Haha! Well, then I'll see what will happen!" After saying that, Rikudō Sennin's Willpower disappeared.

Ryo sighed and entered the building.

...…

A few seconds later, he arrived at Obito's location. The two men meet again after years. Yamanaka Ryo entered Sage Mode as soon as he arrived and felt no signs of Black and White Zetsu. And then said to Obito, "Obito, long time no see!"

Obito wasn't surprised to see Ryo. He had met a couple of times with him. Even in Mizugakure, they clashed using Sharingan. He was even worse at Uchiha extermination night. Pointed directly to the seal in his mind, "Yamanaka Ryo, don't say anything else. You said you would help me release this seal, did you came to fulfill your promise?"

"Of course. But it seems you don't want to cooperate." Ryo said as he saw Obito raised his vigilance.

"I don't know. There's a voice in my head telling me to beat you up. To show you my strength."

Hearing this, Yamanaka Ryo smiled, "Go ahead."

After speaking, Ryo opened his Mangekyou, activated Instant Lightning, and teleported to Obito, punching his abdomen, only to miss.

"Did you activate it earlier?"

"Do you think I will make the same mistakes?"

"You think you'll be safe hiding in Kamui?" After speaking, Yamanaka Ryo showed a large number of ice cubes from the Ice World. The ice cubes filled Obito's doom. Just like when Konan used 600 billion Explosive Tags to bomb Obito in the original manga, Yamanaka Ryo also used a similar technique. Obito's blur could only last for 5 minutes. After that, he must perform the materialization. It's necessary to absorb the ice into Kamui. But once the ice entered Kamui, Obito's blur won't work.

Obito couldn't figure out what Ryo was thinking. He thought Ryo summoned ice cubes to restrict Obito's movement. After a while, Obito realized that he was wrong. Once the blur is over, he will bring those materials into Kamui. He was destined to fail. With the ice cubes, Ryo could teleport inside Kamui and slashed his mask with Ice Scalpel.

"You…"

"Wanna know how I get inside your Kamui? You'll get the answer after I lifted the seal."

After saying that, Yamanaka Ryo teleported in Kamui, holding Obito. Obito felt uncomfortable, but he didn't resist. Ryo laughed and reached out his hand on Obito's head, penetrating Spiritual Strength into Obito's brain. He saw the seal in Mizugakure, so finding it was easy this time.

After some observation, Ryo deducted that the seal planted by Uchiha Madara was mainly his Sharingan, which sealed some parts of Obito's memory.

The seal was enforced by Uchiha Madara's Sharingan. No matter what, ordinary people can't crack the seal unless they also had an Eternal Mangekyou Sharingan. Maybe because Madara was confident that no one could lift it, he left no other protection on the seal. Which was easily lifted by Ryo.

Once the seal was lifted, memories flooded Obito's brain. His childhood in Ninja Academy, friendship with Rin, Kakashi, Ryo, his teacher Minato, and a confession from Rin… After having his memories back, Obito opened his eye and looked at Ryo. His heart was filled with sadness and guilt. What he had done all these years had hurt Rin, Kakashi, Ryo, the village. The shame and guilt made Obito covered his face.

Seeing Obito, Ryo sighed and patted his shoulder, "Obito, it's over now. You did all of these after losing your memory. I think they'll forgive you."

"But sensei… he…"

"Minato is fine."

"Fine? But how? I saw it with my own eyes…"

Ryo laughed and explained to Obito. Hearing the truth from Minato's 'death', Obito relaxed. Obito listened patiently while Ryo explained things that had happened in the village after he lost his memory.

After a while, Obito asked about Rin. This time, Ryo didn't tell him how her condition was, but instead, he said, "Just hearing my words won't satisfy your lovesickness. Let's return and meet her in the village!"

Hearing this, Obito hesitated, "Can I… go back to the village?"

"What do you think?" Ryo asked with a smile.
