The Kuchiki Clan's Forbidden Blade-Universe

Hōgyoku.

Aside from Kisuke Urahara, Aizen, and others who have already defected, Mayuri Kurotsuchi is probably the only one in the Seireitei Mayuri Kurotsuchi knows of this thing's existence.

When Kisuke Urahara was suddenly arrested, many of his experimental reports were left unprocessed.

No sooner had Kisuke Urahara been ordered arrested by the Central 46 Mayuri Kurotsuchi made copies of Kisuke Urahara's reports, both overt and covert.

Soul Reaper's limit is the common goal of all researchers.

What is the Soul Reaper Limit?

For nearly a thousand years, it has been widely believed that the top-tier Captain-level is the Soul Reaper Captain-level.

At that time, only one person exceeded this limit.

Genryūsai Shigekuni Yamamoto.

Kisuke Urahara, on the other hand, took a different approach, attempting to improve by breaking the limitations of Soul Reaper and Hollows, namely Hollowfication and Arrancar.

The technological achievement originating from the soul of the Soul Reaper is called the Hōgyoku.

Although Kisuke Urahara did not leave behind the most detailed data, he had a concrete idea. As a top scientist, he already had enough information. Logically speaking, after decades of effort, he should have been able to replicate it.

Scam.

Mayuri Kurotsuchi ultimately concluded that Kisuke Urahara had been deceiving everyone, concealing the most crucial element that constituted the Hōgyoku.

"His Hōgyoku material couldn't possibly be from Dōsan Hanyū, could it?" Nirvana chuckled self-deprecatingly, then softly uttered a single word, "Soul King."

His Hōgyoku could not take shape because it was missing a certain element related to the Soul King.

What could it be?

What is the relationship between Dōsan Hanyū and the Soul King?

I'm becoming more and more interested in you.

"Great Sage Hanyū, I am hosting a banquet at my home today. I cordially invite you to join me."

"Great Sage Hanyū, please wait a moment."

"The Great Sage Hanyū..."

So, when he has nothing to do, Dōsan really doesn't want to come to Central 46. "Sorry, I have something to do today."

"Great Sage, you are busy."

Dōsan Hanyū nodded in acknowledgment and left using Shunpo. To others, the Central 46 was high and mighty, but to Dōsan Hanyū was so humble.

Everything stems from strength.

"Looks like we're going to be late." Dōsan shook his head and sighed, then pointed to the space in front of him and drew a line. Immediately afterward, a dark space that seemed to be from another dimension appeared in front of Dōsan.

Dōsan stepped inside and appeared in a courtyard the next moment.

The courtyard grounds were covered with pink cherry blossoms, their fragrance intoxicating and irresistible.

"Your Space-Time Kidō is getting more and more proficient." A cool voice came from the side. Soi Fon, leaned against a cherry tree, cherry blossom petals swirling and falling on her shoulder.

"I apologize, the previous trial took quite a while."

"No need to apologize, you weren't late." Soi Fon stated the facts, then hesitated for a moment before adding, "Thank you for your hard work."

Dōsan sat opposite Soi Fon. Soi Fon pushed a prepared sake cup next to Dōsan. The cup contained not sake, but a beverage with a special sweet taste.

It was so awkward, the atmosphere was supposed to be incredibly awkward, but the two of them weren't awkward at all, they drank one glass after another.

This is how they've lived for the past thirty years.

"How is Hisana's health?"

The fact that the current head of the Kuchiki Clan married a commoner from Rukongai shocked the noble lords of Seireitei.

With the complete cessation of the turmoil, Hisana Kuchiki's name became a household name in Seireitei.

Of course, Soi Fon and Hisana Kuchiki became acquainted because the cherry blossom trees in the Fon Clan were gifts from Hisana, and the two became friends as a result.

Dōsan shook his head. "It's not good. His body can no longer withstand the power of spacetime, and I'm powerless to help unless a more powerful spacetime force cooperates with me to completely fix Hisana's body in a certain spacetime."

Well.

It's easier said than done.

In fact, many people find Dōsan Hanyū's Space-Time Kidō to be inconceivable.

The ability of Barragan, the former King of Hueco Mundo Baraggan, to age people is child's play for Dōsan.

If Hisana an inanimate object, he could control Hisana body to remain in the timeline where she was healthy.

However, Hisana a living soul, and a soul without Spiritual Pressure, so while reversing time and space, Hisana is protected from harm.

Dōsan Hanyū alone is simply not up to the task.

Upon hearing this, Soi Fon seemed to recall something, hesitated for a moment, but then spoke directly, "The Kuchiki Clan once sealed away a Zanpakuto through generations, which is said to possess inconceivable spacetime power, and its name is— Universe."

Universe?

This was the first time Dōsan Hanyū had heard of the fact that the Five Great Noble Clans possessed five Zanpakuto through generations. After Aizen defected and took Miroku from the Miroku Shiba Clan, the news had spread among the upper echelons of the Seireitei. At least among the Commander of the Punishment Force, it was no longer a secret.

"Universe, universe... universe."

Dōsan muttered softly, "If that's the case, perhaps we can really save Hisana. Her time is running out."

Soi Fon shook her head. "These Soul King Blades have extremely severe side effects. Although I don't know what they are, if they could be used freely, the Kuchiki Clan wouldn't have chosen to seal him away."

"I believe Byakuya will definitely choose to use it."

Because of love?

A strange unspoken understanding arose between the two, and Soi Fon softly hummed in agreement.

The wind was a little noisy, and the flowers smelled sweet.

"Speaking of which, do you know the name of the Zanpakuto that the Shihoin Clan Zanpakuto through generations?"
