My Sign-in System in Naruto

After the commotion ended, Haru returned directly to his room.

Although the process had been a bit convoluted, he had managed to obtain a sheath.

The one he got from Ikkaku was a traditional Japanese-style sheath, simple in design but effective in protecting the blade.

Haru sat cross-legged on the tatami mat, placing the Asauchi across his lap. Slowly, he drew the blade from its sheath.

From what Haru understood, whether the Asauchi awakened into a Zanpakutō depended entirely on its user.

Perhaps interacting with it in this way could speed up the awakening process.

However, the moment Haru drew the Asauchi from its sheath, the tatami beneath him, the floor, and even the surrounding walls and ceiling began to erode at a visible rate until they completely disappeared.

"Where is this…?"

Haru stood up, only to find that the Asauchi in his hand had also vanished.

Looking around, he saw an endless desert.

Clearly, this wasn't the inn in the Land of Iron but a strange, otherworldly space.

"The inner world of the Zanpakutō," Haru muttered, frowning slightly.

He vaguely remembered that when Ichigo Kurosaki, the protagonist of Bleach, awakened his Zanpakutō, he entered an inner world. There, guided by Zangetsu, he found his Zanpakutō and achieved its Shikai.

However, Haru wasn't trapped here. He could feel that if he focused, he could leave this space at any time.

"Speaking of which, when Ichigo first entered his inner world, Zangetsu was there to guide him."

As Haru muttered to himself, he looked around. The sun blazed overhead, and there wasn't a cloud in sight. Aside from the endless expanse of yellow sand, there was nothing here.

"Is anyone here?"

Haru took a deep breath, infusing his voice with chakra, hoping for a response.

The moment Haru's voice echoed, the desert beneath his feet began to tremble.

"So…"

Haru looked down. The sand beneath him seemed to awaken, rising rapidly and carrying Haru with it.

Although this was the inner world, it didn't strip Haru of his abilities.

Because of this, Haru didn't need to hold back. He unleashed his full chakra, causing the sand beneath him to twist and writhe in a bizarre manner.

"It's alive."

Haru's brow furrowed. Before destroying this massive entity, he wanted to see what his inner world would manifest.

With a light tap of his foot, Haru leaped backward, putting distance between himself and the rising sand.

At the same time, Haru got a clear view of the massive entity beneath him.

It wasn't just sand it was a towering earth giant, awakening from the desert.

Even its skin tone seemed out of place against the yellow sand.

"But… why is my Zanpakutō's manifestation this image?"

Haru couldn't help but sigh, feeling slightly disappointed. He had expected his Zanpakutō's manifestation to be more impressive.

Although he didn't fully understand the principles behind Zanpakutō, before entering this inner world, he was a ninja proficient in all five nature transformations and swordsmanship. He also possessed the Wood Release and Byakugan kekkei genkai.

"The five nature transformations…"

As this thought crossed his mind, Haru's expression grew serious.

"Could it be that because of the five nature transformations, my Zanpakutō has awakened five different inner worlds?"

Haru took a deep breath, deciding to focus his attention to test this theory.

However, just as Haru prepared to explore other inner worlds, the earth giant below suddenly opened its massive maw and let out a deafening roar.

"Who dares disturb me?!"

Although this was Haru's inner world, it was also the inner world of his Zanpakutō.

After all, the Asauchi became a Zanpakutō when the user infused it with their soul and beliefs.

Of course, almost every Zanpakutō was inherently proud. Their relationship with their wielder was more akin to that of a Jinchūriki and their tailed beast.

Before becoming friends with their wielder, entering their shared inner world would only provoke resistance.

While tailed beasts were bound by seals, Zanpakutō could move freely within the inner world.

In other words, a fight was inevitable.

However, Haru wasn't worried. Like the earth giant before him, he wasn't restricted here either.

Clap!

Haru took a deep breath and brought his palms together. "I don't want to hurt you."

"Heh."

Haru's words elicited a cold laugh from the earth giant. It raised its massive arm, clenched its fist, and swung it toward Haru.

"Are you saying you can easily hurt me?"

The earth giant's fist, carrying immense force, hurtled toward Haru.

In truth, the moment Haru entered this inner world, the earth giant had recognized his identity.

But it had no intention of submitting to someone it deemed weak.

In its mind, it was the master of this world.

Haru was merely an intruder.

And now, it would expel him.

Either leave or die here.

"You're quite arrogant," Haru said in a low voice, unleashing the Wood Release: Deep Forest Emergence.

This was his inner world. No matter how much power he used, it wouldn't affect the outside world.

So, at this moment, Haru held nothing back. He unleashed his full chakra, creating the most powerful Wood Release technique he had ever used.

Boom!

The ground shook violently, far more intensely than when the earth giant had awakened.

Massive trees sprouted and grew at an alarming rate, even shocking the earth giant.

The giant's fist, aimed at Haru, was blocked by a colossal tree. Branches, like vines, quickly wrapped around its arm.

In a matter of moments, the earth giant's massive body was completely restrained by countless trees.

The once endless desert had transformed into a dense forest.

"I am the master of this world."

Haru stared directly at the earth giant, using the forest to pull at its legs.

Crash!

With a deafening roar, the earth giant's legs buckled, its knees and shins slamming into the ground, causing the earth to tremble once more.

But just as Haru prepared to force the earth giant into submission, a thunderous crack echoed from the sky.

A lightning dragon, carrying the force of a thousand storms, descended, its maw wide open as if to devour Haru.

If the earth giant represented earth release, then this lightning dragon likely represented lightning release.

"So my Zanpakutō is multi-attribute."

Haru's gaze sharpened.

In his understanding, Zanpakutō typically had only one attribute.

Haru looked up at the sky. "Is there more? Why don't you all come at me together!"
