XX-level Hokage

After Tianchen was born, Black Zetsu was placed by Mashiro to be by Tianchen's side.

"Brother Hei Jue, when will I be as strong as Father?" Tian Chen whispered.

“Don’t worry, you are your father and mother’s child. Sooner or later you will reach your father’s level and then inherit his empire,” Black Zetsu said.

“In terms of inheritance, the one most qualified to inherit our father's position should be my younger sister, Yu Zi,” Tian Chen said softly. Heh, don't worry, Tian Chen, only you are qualified. You'll understand later.

Chapter 1: Mashiro

Mashiro opened her eyes and was greeted by an unfamiliar scene.

The sky was a strange grayish-blue, as if shrouded in a thin layer of mist. Faint spiritual energy fluctuations filled the air, and the sound of dripping water could be faintly heard.

The scenery here is completely different from that of the ninja world. There is no sun or moon in the sky, but the light is very abundant, as if the whole world is shrouded in a soft halo.

A faint spiritual energy fluctuation permeated the air, and the surrounding plants also emitted a faint spiritual light. "Is this the Soul Realm?" Mashiro muttered to herself.

"Yes, host, this is the Tokishin World?" A weak voice echoed in Mashiro's mind. Closing her eyes slightly, Mashiro began to recall information about this world.

"In the primordial world where there was neither birth nor death, the Hollows continuously devoured humanity. If this continued, only one incredibly powerful Hollow would remain in the primordial world. As if the will of the world was trying to prevent this from happening, the Spirit King was born. The Spirit King destroyed the Hollows, and then one after another, powerful beings appeared. Among them, the ancestors of the five noble families, because they believed that the world should move forward, used the Spirit Lord to divide the primordial world into three realms. Later, the ancestor of the Tsunayo family ambushed and sealed the Spirit King. Over a long period of time, the four families other than the Shiba family cut off the Spirit King's limbs and heart, crushed the Spirit King's organs, and then sprinkled them across the three realms."

After that, the Spirit King always existed as a wedge to stabilize the balance of the three realms. It is said that the Spirit King did not resist at all during the whole process, and the God of Death was born as a result and has always been the maintainer of the balance of the three realms.

Based on the varying concentrations of spiritual particles within life forms in different worlds, different races have emerged. Humans, located in the present world, are one such example.

Souls: The souls of the dead are called souls. Souls are guided by the Grim Reaper to the Soul Society. If the souls of humans who die in the mortal world are attached to the mortal world for some reason and refuse to go to the Soul Society where souls are placed, they become wandering ghosts. "Souls usually do not endanger humans and will talk to those who can see them. However, "If a soul is not guided to the Soul Society in time due to its deep inner desires, it may become an evil spirit, also known as a Hollow.

Void: In the mortal world, after a period of time, the desires within the soul will corrode the body, causing it to transform into a "void," that is, an evil spirit. The void will devour everything in its path.

They devour the souls of other living beings, especially those they loved in life. Hollows generally seen in the mortal world still retain the ability to communicate with those who can see them, meaning their reason is not completely extinguished. Since most Hollows still have a conscience deep within their hearts, they can still transition to the Soul Society to await reincarnation with the assistance of other spirits. However, most Hollows reside in Hueco Mundo, and their power and size are far greater than those Hollows that have fallen into the mortal world. They are enemies of the Shinigami and humans, and are collectively known as the Great Hollows.

Shinigami: Life forms with extremely high spiritual particle concentration, possessing abilities surpassing those of humans. They can also fight Hollows due to the high concentration of spiritual particles within their bodies, and are also the Hollows' favorite food. Shinigami are responsible for protecting humanity, guiding and purifying Hollows, and returning them to the Tokonome, maintaining the balance between the two worlds to prevent their destabilization and destruction. They are also the rulers of the Tokonome.

An incredibly complex world.

"By the way, System, what is the objective of this mission?" Qi Bai asked softly, "Kill the Spirit Lord and unify the Three Realms," the system replied.

"I knew it," Mashiro said with a helpless expression.

"To be honest, the difficulty of this mission exceeded my expectations. It was only because 086 and 011 recommended you, host, that I was willing to give up on this mission," System 045 replied weakly.

"After all, resetting your stats and starting over is incredibly troublesome, especially since I'm just a clone," Mashiro said softly. One day earlier.

Hyuga Mashiro, the emperor of the ninja empire and the queen of the ocean, once again dreamt of the pale world. This time, it was System 086 who came to her.

"Host, it's been a long time. How have you been?" A pale purple sphere appeared out of thin air, and System 086 spoke. "You suddenly appeared; is there something you need?" Mashiro said calmly.

"Ah, um, well, there's something I need your help with," 086 said somewhat embarrassedly. "It's not some kind of mission again, is it?" Mashiro suddenly realized something.

"Hehe, you explain it yourself, 045. 086 said, and a pale red sphere appeared in the pure white space. 086, is she the top-level host that you and 011 were talking about?" 045 looked at Mashiro and said in an extremely calm tone.

“That’s right, she’s very capable. She’s one of the few who can handle a Ruined-class mission, and she’s done it twice,” 086 replied. Hearing 086’s words, 045 curiously circled around Mashiro a few times.

"Excuse me, would you like to travel to other worlds?" The pale red sphere stopped in front of Mashiro and asked earnestly. Hearing this, Mashiro turned to 086 and said, "Did you all come to me just to say that?"

“There’s no other way. Before you appeared, the completion rate for the Ruined-class missions was 0%. Number 045 is my predecessor. Due to that accident, the mission it drew this time has changed. The original host couldn’t complete it at all, so it contacted me, and then I recommended you to it,” 086 explained.

"Is it another world...?" Mashiro muttered to herself.

"Don't worry, just like last time, once you go to that world, time in your current world will immediately stop until you return," 086 added.

"Can you tell me what kind of world this is?" Mashiro asked softly, looking at 045.

"I'm sorry, but I refuse this time." After 045 finished speaking, Mashiro directly refused. "Um, could you tell me why?" 045 wanted to argue her point.

Upon hearing Mashiro's reason, 045 was speechless.

“However, if you really have no other choice, you can try using her.” With that, Mashiro opened her hand, and a sphere floated out. “What is this?”

"My soul, or you could say a part of my soul."

"086, what do you think?" 045 asked, looking at the soul inside the sphere.

"That depends on you, 045. I'm just recommending someone," 086 replied. In the end, 045 chose to compromise and began a new mission with the disintegrated soul of Mashiro.

"By the way, System, what form will this system assistance take? Is it favorability, recognition points, or something else?" Mashiro asked. (Author's Note)

I plan to post the One Piece side stories directly to the group chat. Posting them on other platforms would require editing and re-editing. Starting tomorrow, I'll post one story a day.

I'll post the White Star chapter tomorrow.

Chapter 2: Yamamoto Shigekuni

“Sorry, there’s no lottery or special reward this time, just some extra points,” 045 replied. “Extra points?” Mashiro asked, somewhat puzzled.

“Just look at your own panel and you’ll understand,” 045 said. Filled with doubt, Mashiro checked her system panel.

"Although I cannot transplant your original abilities due to the special circumstances of this world, I can manifest your power through your Zanpakuto based on the remnants in your soul."

"In short, awaken your Zanpakuto first." 045's voice grew even weaker. "How do I awaken it?" Mashiro asked.

"Close your eyes, search deep within your soul, see that knife, and say its name," 045 replied. Then, Mashiro closed her eyes.

Her thoughts were heavy, sinking into the depths of her soul.

First came complete darkness, then a dazzling array of light, and finally a grayish-white radiance, within which a long, slender katana fluttered.

Looking at the katana, Mashiro felt a resonance with her soul. Almost involuntarily, a name appeared in her mind.

"Zero White" quietly opened her eyes.

A katana with a new gray blade and seven dazzling gems inlaid on the hilt appeared in Mashiro's hand.

"Is this my Zanpakuto? It looks pretty good," Mamoru said softly. 045 did not respond.

"Is it asleep? Yes, it is."

Mashiro, the Shinigami, scanned his surroundings.

This place seems to be on the outskirts of some street, and traces of a village can be faintly seen in the distance. "Anyway, let's find a place to read a book."

Just as Zhen Zi got up and started walking towards the village, a commotion arose. "Make way! Make way!"

A group of wandering spirits scattered in panic, and before Mashiro could react, she ran past her. "What happened?"

Looking back, Zhen saw a tall figure walking towards them.

The man was dressed in a simple shihaka outfit, with an ancient samurai sword at his waist. His eyes were sharp as knives, as if they could see through everything.

Name: Yamamoto Shigekuni (Yamamoto Genryusai Shigekuni) Gender: Male

Zanpakuto: Ryujin Jakka

"Yamamoto Shigekuni..." Upon seeing this name and information, Mashiro instantly had an idea. "Wait a minute!" Mashiro immediately rushed out and blocked Yamamoto Shigekuni's path.

Yamamoto Shigekuni frowned slightly, stopped in his tracks, and stared coldly at the girl who had suddenly appeared. "Who are you? Why are you blocking my way?" His voice was deep and authoritative.

Mashiro took a deep breath and began her performance, saying, "I...I am Mashiro. I know your name, Yamamoto Shigekuni, the holder of Ryujin Jakka."

A flicker of surprise crossed Yamamoto Shigekuni's eyes, but it was quickly masked by indifference.

"What nonsense are you spouting? What future? What Ryujin Jakka?" His tone was displeased.

Mashiro knew that it would be difficult to convince Yamamoto Shigekuni with just a few words; she needed to provide more compelling evidence.

"Your Zanpakuto, Ryujin Jakka, its first release phrase is 'All things return to ashes.' Ryujin Jakka!" "Isn't that right?" Yamamoto Shigekuni's pupils contracted sharply, and his hand involuntarily gripped the hilt of the sword.

"Who exactly are you? How do you know my Zanpakuto's power and Shikai? What is your relationship with the Eye Monk?" His voice turned low and dangerous. "I'm sorry, I don't know any Eye Monk. As for why I know your Zanpakuto's name and Shikai, it's because my eyes can see things that ordinary people can't, including other people's Zanpakuto names and Shikai."

Yamamoto Shigekuni remained silent for a moment, scrutinizing Mashiro with piercing eyes.

“Your ability… is quite special.” He finally spoke, his tone still cold, “but that cannot be a reason for you to stop me.”

“I know this is incredible, but please believe me, I mean you no harm,” Mashiro said earnestly. “I only want to follow you and become your partner.”

Yamamoto Shigekuni frowned slightly, clearly somewhat surprised by the suggestion.

"Follow me? Do you even know who I am?" His tone was laced with sarcasm. "No," Mashiro replied honestly.

Yamamoto Shigekuni remained silent, seemingly deep in thought. "Why do you want to follow me?" he suddenly asked.

“Because there is one thing I am sure of: you are strong, extremely strong, and you can give me power. My parents died at the hands of Hollows, and I don’t want to repeat their mistakes.” Mashiro met Yamamoto Shigekuni’s gaze without fear. “That’s why, even though I might be killed by you, I still want to take the gamble. I want to become stronger, and I want to change my destiny.”

"Change fate?" A hint of doubt flashed in Yamamoto Shigekuni's eyes.

"Yes, I want to become as strong as you. I want to have the power to change my destiny and walk my own path of justice," Mashiro said earnestly.

Yamamoto Shigekuni looked at Mashiro with a complex expression in his eyes.

Even so, what can you do? His tone carried a hint of doubt.

“I can help you,” Mashiro said without hesitation. “My abilities can give you an advantage in battle, and I have great talent. If you are willing, I can grow incredibly fast.”

Yamamoto Shigekuni remained silent for a moment, then sneered, "Do you think I'd believe your one-sided story?"

“I know this is hard for you to believe, but I’m willing to prove it to you,” Mashiro said firmly. “Just give me a chance.” Yamamoto Shigekuni looked at Mashiro, a hint of amusement in his eyes.

“Alright, I’ll give you a chance,” he suddenly said. “Come with me.”

Mashiro was not surprised by the result and quietly walked to Yamamoto Shigekuni's side.

"Is that your Zanpakuto in your hand?" Yamamoto Shigekuni asked, glancing at the katana in Mashiro's hand.

“That’s right, its name is Zero White,” Mashiro replied. “Have you mastered Shikai?” Yamamoto Shigekuni continued to ask.

Mashiro shook her head and said, "Even my Zanpakuto awakened by accident."
