Sasuke Comes, Call Grandma

As Tsunade spoke, she swept her gaze over the surroundings. The sky had grown even darker, yet she still had not caught sight of Kaguya Otsutsuki.

Had Kaguya's Shadow Clone already been dispelled? Tsunade's intuition told her otherwise.

She always lost when gambling with money.

But when she gambled in battle, her instincts had never led her astray. Otherwise, how could she have survived until today?

The sky grew darker still...

Wu Yu was also watching the sky above the forest. The moon was bright and clear. By this time, Naruto Uzumaki should have already found Mizuki's hiding place deep within another forest and learned the Multiple Shadow Clone Jutsu, right?

"I do know quite a few things about her."

Wu Yu withdrew his gaze and met Tsunade's eyes. "But for now, I haven't decided how much I can tell you..."

Tsunade turned serious. "Is it something very grave?"

Wu Yu answered just as seriously, "It's very valuable information. I think that if I reveal it at the right time, I can get a better return."

Tsunade gave him a deadpan look. "..." This brat!

"Then I'll tell you one thing first!"

Wu Yu smiled and raised a finger. "The method she used to create the child in your belly... was Yin-Yang Release."

"..."

Tsunade's pupils contracted, clearly shocked beyond measure.

Her thoughts churned wildly. Yin-Yang Release, Yin-Yang Release Technique...

If she remembered correctly, both the ancient texts passed down within the Senju Clan and Grandfather Tobirama's research notes contained fragmentary descriptions of it... It was said to be the ninjutsu the Sage of Six Paths had used in myth to open up all things and create everything!

"Anyway, that's all for now."

Wu Yu prepared to leave, waving two fingers. "It's getting late. Sasuke said he'd let me stay over at his place. If there's nothing else, we'll be going now. See you~"

Wait, when had I ever agreed to let you stay over?

Sasuke Uchiha stood nearby in speechless disbelief, yet he still unconsciously moved along with Wu Yu.

"Wait!"

Tsunade stopped the two as they were about to leap onto the trees. Pointing at her abdomen, she said to Wu Yu, "This... Spirit Immortal, whatever you call it, has the same nature as a Tailed Beast. It can't simply be left alone. It must be sealed. This is not only to protect it, but also to protect the Jinchuriki herself."

Once a Tailed Beast was extracted from a Jinchuriki's body, the Jinchuriki would immediately die.

The same was likely true for a Spirit Immortal's Jinchuriki.

Fuinjutsu was like a complicated combination lock. Even if something unfavorable happened, an enemy would first have to get past the seal.

"I really hadn't considered that..."

Wu Yu stood sideways against the tree trunk and smiled at Tsunade. "I don't know Fuinjutsu, so I'll leave it to you. Sasuke, hurry up. Aren't you hungry?"

Whoosh! Wu Yu leaped into the dark forest, heading south toward Konoha.

Sasuke Uchiha glanced at Wu Yu from the treetops, then looked back at the spot on the tree trunk where Wu Yu's feet had seemed to stick sideways. After giving Tsunade on the ground one final look, he too dashed after Wu Yu with a whoosh—.

"..."

Tsunade watched the two depart and let out a long breath.

Haotu asked curiously from within her body, [Tsunade, are you worried that Lord Wu Yu might harm you?]

Tsunade replied, "I'm more worried about your 'Mother.'"

Kaguya Otsutsuki... Yin-Yang Release... the Creation of All Things Technique...

Those Byakugan... and the one on her forehead...

Tsunade still vividly remembered Mysterious Kaguya's three eyes. She thought, They say the Hyuga Clan, with their Byakugan, is the most ancient clan. There are even rumors that if one traces the Uchiha Clan back to its source, they too originated from the Hyuga... Now it seems that such an outrageous claim was not without reason, since those proud Uchiha never denied it.

[Tsunade, does the Fuinjutsu you mentioned mean you're going to lock me up?] Haotu yelled by her ear. [I don't want to! I don't want to! Don't lock me up!]

"I won't. I promise."

After saying that, Tsunade also turned into a dark blur with a whoosh—, disappearing into the depths of the forest.

Whoosh, whoosh, whoosh...

Wu Yu and Sasuke traveled through the forest one after the other toward Konoha, moonlight rippling over them in alternating flashes of brightness and darkness.

"What price must I pay to obtain the rabbit-like power you and that Tsunade used?"

Hearing the sudden question from behind him, Wu Yu, who was hurrying ahead, could not help but give a deadpan look.

As expected, he still asked.

Was I supposed to tell him that as long as he waited patiently for another three or four years, he would become strong enough to split all of Konoha in half with a single slash?

Wu Yu glanced back at Sasuke. The latter had his head lowered as he closely followed Wu Yu, darting between treetops—the common way ninjas traveled.

"It's not called rabbit power. It's called Sage Chakra."

Wu Yu said, "The natural environment is filled with Nature Energy that ordinary people cannot perceive. As long as it is absorbed and mixed with a ninja's Chakra in balanced proportions, it can form Sage Chakra. What Tsunade and I used was merely Sage Chakra itself 'coming alive.' It wasn't any stronger than Sage Chakra that hadn't come alive."

Sasuke Uchiha said nothing and silently continued following behind Wu Yu.

Whoosh, whoosh. One after the other, they leaped out of the woods and arrived on the streets in northeastern Konoha. It was already late at night, and there was not a single pedestrian on the road.

Sasuke Uchiha suddenly asked, "You said you explained it to Tsunade because you trusted her. Then why did you let me hear it too...?"

Wu Yu slowed to a stop, turned back, and smiled. "Of course it's because you're trustworthy too. Isn't that obvious?"

"..." Sasuke looked up at him, biting his cheek tightly as he kept his expression taut.

Wu Yu snorted. "If you're touched, then show it. Is your idol image really that important? Also, hurry up. I don't know where your house is, so lead the way."

So Sasuke took the lead, bringing Wu Yu into the Uchiha Clan compound.

This place was close to the eastern woods and training grounds, already on the outskirts of Konoha. Ever since the Uchiha Clan had been exterminated, it had remained desolate for a long time. Walking through the streets in the dead of night felt like wandering through the set of a horror movie. Sasuke living here alone made him seem like the male lead of a supernatural film.

"I forgot to introduce you."

As Wu Yu followed Sasuke toward his residence, he snapped his fingers at the space beside him. "Come on, Sasuke. Call her Grandma."

Huh?

Sasuke was utterly confused. At the gate of his own home, he turned to look beside Wu Yu. In the dim night, an ashen-white figure slowly emerged from the air, like a Female Ghost. It was the horned, three-eyed woman who had previously used what Wu Yu called Yin-Yang Release to create two rabbits.

My grandmother?

My grandmother looked like that?

...Sasuke did not believe it at all, but he had never actually seen his grandmother!

Wu Yu also glanced at Mysterious Kaguya beside him and thought, Now here's the problem. If I dispel Kaguya's Shadow Clone, will her memories return to me... or will they flow to Kaguya Otsutsuki's true body, currently sealed inside the Demonic Statue of the Outer Path?

...Fuck, I'm already a little scared to dispel her and have it all go to hell.
